2000s Jaguar XJ8 Problem Resolution: NO START, WON'T CRANK
HTML-код
- Опубликовано: 27 ноя 2019
- It's winter, and my 2003 Jaguar XJ8 (99k miles) has been reacting badly to the cold. First it did not properly auto unlock the other day at the gas station, locking me out. And then I came out the other morning to start it up and it was dead - no crank, no start. After spending some time charging the battery, thinking that either it was failing in the cold weather or there was some other electrical issue, I discovered the key I had been using - my spare key - had mysteriously stopped working. This is the first time I've ever had a failed security KEY be the reason a vehicle would not crank. The keys have embedded security features, but apparently this one has gone bad. Maybe other Jaguar owners will be helped seeing this. Luckily, I had two keys, so I can still drive it, but no fun knowing I'm down to just one key.

I feel you man! Quirks in every car I've owned... Laughed out loud at your error lights. Mine's like a Christmas tree too. All the best to you and yours Brad.
As someone else mentioned...lube the tumblers in the switch...PB Blaster instead of WD. Go online and look up the sequence to reset the security system. For background: the keys have a resistor in them that triggers the security system to allow power to go to starter, when the sides get worn on a primary key, they don't make good contact and will not work. I have bypassed these before and I have also put a small blob of solder on each side of a key to make it work again. Get a resistance reading first or the dealer will charge you huge bucks to figure out which key/resistor you have if you ever need another new key. Since your new key is not working, but the old one is again, I would suspect worn and stuck tumblers in the lock before anything else. Another item you can check since it is an intermittent problem...most of these systems have 2 wires that connect to the back of the lock assembly...those wires turn everytime you turn the key and eventually break off, but may still make intermittent contact whenever they happen to fall into the right position. Since you have defeated your neutral/park safety switch by breaking the shifter assembly...that of course could be the problem also...wiggle the stick while trying to start and see if that helps. You can also bypass the key resistor all together by getting a resistor reading off of the key, buying a resistor of that value or +-10% and finding the two wires that come out of the steering column at the bottom and go into a connector...put the resistor across the two wires/connector going back into the vehicle harness (not up into the column)...you will no longer need a chipped key, though they still will be used, and your security system will be bypassed (Actually circuit completed with right resistor reading going to the alarm control box so completing the circuit needed)so your doorlock problem may go away at the same time.
Mannnn u sound like a life saver! I've tried almost everything to get this pos started! NVR heard about this! I think a lot of us pos jag owners may owe u something!!!
Love the Jag and love the Anchorman "I'm kind of a big deal" t-shirt
Thank you for sharing! I'm Learning a lot and love my jaguar xj8l
I have a Fender Jag that needs to be tuned all the time. Might need to be tuned. Great channel Brad
When I started buying jags someone said you better buy a pair of walking shoes with it and boy that was the truth😂
Not with mine. Definitely depends on the model!
Those keys (like many other manufacturers) have chips in them. If they stop working properly essentially the key is no good. This was a worthwhile video to watch for sure in case you do not know about the keys with chips built in. Hope you and your family had a great Turkey day Brad.
I was ready to say "I'll have two over easy with bacon" and then I realized that this wasn't "shit post fried egg"...
cold weather always fades batteries here, you have to hold the headlight flasher back to pair the key with the car, i would google how to do that.
yes, had a similar problem with the door actuator when it was a bit cold; forget how i got back in the car to start it.
Very helpful…Thank you
I just replaced the guts of my Acura key. My main key just seemed to get tired; not transmit very far, take multiple tries to unlock the door(s), etc. Backup key worked fine. After I replaced the electronic part of the key, the mechanical part had to be re-synched to the ignition, which on the Acura is really easy. At first I thought you had a parasitic drain caused by a defective relay. These things sometimes slowly leak to ground and everything in the car is dead the next time you try and start it ... even though the battery and charging hardware all seem to work just fine. In the Acura it was an AC relay sticking closed which meant I was probably working the heck out of my compressor with the clutch always engaged.
I'm in NY, so when I went to Florida a few years back, my motel had RFID card for the key to get in and if I had too close to my phone when my NFC was on, the card would not work and it cleared the card. Reset the codes or disconnect the battery and press on the brake to get rid of any electrical charge the reconnect it. The key may have to be re-programmed. Your computer or one of them may be failing.
The XJ8 is like a hot girlfriend it looks good but it’s a headache when you get it home.
Lol.
Not if taken good care of
Had a key issue similar with my El Dorado... the key had a little resistor bead that changed its value somehow.
There’s ways to bypass this problem on Cadillacs, but idk about Jags.
Good luck, boss.
Cool Jag! I've got a 2000 S-Type V6 240 HP.
I bought a second key fob for my 2004 Totyota Avalon and you have to go through a bizarre sequence to have the key be recognized by the car - something like turn the key on/off 3 times, hit the brake pedal 6 times, etc but it eventually worked. Can't explain why the key went dead but look up how to reprogram a key to your jag.
What do you expect Brad? It's British! Over here in the UK it is one of those things. The keys are not powered at all, they use induction to operate in the same way as the swipe cards on door entry systems. The Key is passive and the car senses the correct rfid chip and disables the immobiliser. Sounds like your spare has been blocked out by the car and needs to be re-enabled to work.
Reminds me of problems with the"valet" key and keys with a bad chip in them. Was thinking it might have been your transmission sensors, but since the primary key still works, it is a bit baffling.
Is there a battery in the key that powers the immobiliser? If so, could be the spare is dead. Or if a chip, could it have been affected by a strong magnet on the safe?
Thank you! You need a mechanic like mine! Find someone who has been in business a long time, independent shop, cheap and reliable.
dang, Brad. I’ve been subbed to your other channel forever.
if you don’t know what Brad is: he can fix anything electronic & I mean everything, so feel confident in listening to him.
what was the fix here?
The key don t works with the remote control ? perhaps the remote opener need new battery ?
i mean , if the remote don't have battery , the key only don t work ( like a double check )?
There are transponders in the keys that are coded to the ECU. If they are not recognized correctly, the car won't start. Because your car has an autosensing system to unlock the doors, i would also suspect that there is something wrong with them. For an old car like this i would recommend to buy a Jaguar diagnostic system (there are also JLR knock offs) to read the DTCs and check what is wrong. Maybe guys in a Jaguar forum can help.
Brad, you know how electronics work when they get old - grounds go bad. I suspect you have a ground issue at some point, possibly intermittent, and the ECU is not sensing signal correctly. That could explain the low coolant level, low squirter juice level, RFID transponder having sensitivity issues (the possible cause of one key not working) and so on. I'd pull the ECU harness and look for corrosion. I bet you are going to find a common cause for a lot of the electrical issues. Good luck!
did the first key put your ignition lights on .i can see the 2nd did and started it but could not see the first .
First you'll need some eye of newt, some carrot chips and a pan of water. Bring water to a rolling boil and add the carrot chips (as seen on classic Bugs Bunny episodes) add the eye of newt slowly stirring until fully dissolved. Once those steps are done go ahead and forget the crap I just had you make, grab the keys and head down to a mechanic and see what they can do because I have no Idea, :) Happy Thanks Giving Brad, :)
Did you have any issues with the steering wheel adjusting itself when driving, if yes how did you resolve ?
The key has a transponder. It 'reflects' a startup code back to the car, indicating it is coded to that specific vehicle.
Try this first: Try to start the card with the 'bad' key while holding the 'good' key in the same hand.
If it starts, the system is reading the 'good' key your transponder is defective or missing.
If defective, you can have it reprogrammed by the dealer, or any competent locksmith that specializes in automotive repairs.
If missing: Look for a small, round indentation at the top of the key, about the size of a pencil lead. If there is a tiny hole, the transponder has fallen out. (I have never heard of this happening, but I suppose it's possible.)
Tibbes keys are available online, complete with a 'generic' transponder. You'll have to have the key cut by the specialist before it's sent to you. (It is very inexpensive.)
[nice, looking jaguar]👍
There's a chip in the key, that is matched to your car. I think your 'host' of problems comes down to the engine management light which is on. There are obviously some issues with it. Best thing is to take it to a dealer or a garage that you're happy with and get them to put their laptop on it, and reset the codes. I think then, you will probably find that your spare key which came with the car, will most likely work . . .Good luck!
I notice you have an engine coolant low light on. I,m at 62000 miles on my 2003 and I cant get rid of this light？ Any ideas？ Also、I had same starter problem。 Problem was crankshaft position.
I hear alot of chat here..but thanks for the post?..after trying to jump my car... knowing my battery was good....I didn't think of my spare key...which at first only unlocked the the door and trunk....but after the video..I tried it and the car started.....I like my car.... thanks
Seems to me that the transponder in your extra key is bad. Sometimes you can simply put the key with the working transponder directly underneath the lock cylinder while attempting to start the car with the inop key. It might help narrow things down.
Old turntables? You just became interesting . I had a 2000 VDP and I loved it but the transmission went out at 40K and even though it was repaired under warranty I couldn't trust it anymore so i sold it. Where do you live that a cop brought you home to get your key? Don't see that happening to me.
Hmmm I brought a 1998 XJ8L with 109k to NY from Vegas, where it’s spent most of its life in warm weather, but it seems to be doing okay even when it’s 20 degrees or lower.
I'd consider just getting all those error codes cleared. My 01 230SLK has a fun trick of slamming on the front right brake for half a second once in every journey but if you go and get the error codes cleared, not just the main ones but in the sub-menus too then it doesn't do it for months. Could there be a battery in that key? I'm pretty sure not looking at the answers below. I like the idea of checking the physical dimensions of the key, see if it's worn. Looks like a simple resistance check is involved. Keep your lovely Jag mate and get a shitter for just in case. By the time you'd fixed it up so you could sell it you'd have a lovely car worth keeping. Could you imagine enjoying a 300C after an XJ8?
the not shifting is prob the park shift interrupt solenoid, which could be causing the no crank no start issue. Have you tested the battery in your keyfobs? Some cars rely on that to send a signal to the cars security. Might not hurt to blow out the ignition switch cylinder, but be careful spraying liquids in the lock cylinder as it can short the security switch and really cause problems.
I don't know a lot about Jaguars but recently inherited a 2006 Lexus RX330 with 40, 000 miles that has always been maintained and technically it's not even " broken in yet" .
The motor runs beautiful, I had it repainted, detailed, did a complete leather clean and restore.At this age baking in the Florida sun little crap is breaking and as you know especially " Jags" are a fortune for parts on the used market too.I was surprised as well with the" glorified" Toyota parts.I think I could do without some of the luxury and keep it simple.My $.02
[thank, you for you're helpful video]👍
My Dad's a locksmith and he said to take the key to a locksmith and they can reprogram the key. It shouldn't cost as much as the dealership. Every once and a while they lose their programming.
Why did you let everything get so far behind on maintenance?
Ask Scotty, he's an excellent mechanic youtuber. He considers these 'endless money pits'
Scotty's a real hoot but he needs to put out more content...
Scotty Kilmer is one of my favorites: ruclips.net/user/scottykilmer
Yeah he’s a great mechanic, but his videos are fucking ridiculous! The most insane clickbait, that to get any decent info out of his videos I have to go way back.
@@graxjpg scotty even has a clickbait video about clickbait
Scotty wouldn't help, he'd probably tell you not to drive a Jaguar.
I love British cars( Land Rover) and motorcycles (Triumph ,BSA) but, they have always had "shite" electrical systems ,I know this from experience as I am a retired Motorcycle Mechanic and occasional classic car owner. P.S. I hope you had a great Thanksgiving Brad.
Lucas!

Try changing the battery of the key fob on the non-functional key. Maybe the RFID chip is in the fob, not the key.
True.
Idk your situation with the jag video being a yr old. What happened did you figure out what was causing the problems?
Nice one Brad: Maybe get one of those OBD II diagnostic jobby things from ebay about $10 if you have the port for it.
My Ford Focus is 13 yrs old and I filmed it from 99999 to 100000 - still going strong though (it's a diesel 1.8 Ghia) - part of the family.

I had an XJS with a V12 that was nothing but headaches the worst of which was that"Ten" was stuck in the CD player and I was besieged by Pearl Jam anytime I drove it...
That’s hilarious.
I had a 94 mercury cougar I bought off some old guy with a Donny and Marie's greatest hits cd stuck in the player that he did not mention when I bought it. I was 18 and got dumped by my first gf and was so depressed I left in their for a week and actually listened to it. It will be the 12th of never before I buy another used car without checking out the radio first.
"Thinking about boiling the key." 🤯🤣
My car does same thing sometimes, either a solid click or no sound at all
Transponder issue, However since you have engine check light resolve that first. Food for thought Brad, Had a no start prob with my dads car, Mechanic came out with his code reader couldn't get it started.He did say that the code he had was saying the the injectors where in operation as if engine was running, Erasing codes just didn't work, I know its not the same as your problem Also I'm saying it might not work for you, I just disconnected battery for at least a day ,I was thinking Cap's in the the brain/ module holding charge, Connected battery again and it started with no engine check light
The back up key probably needs to be reprogrammed. You can find how-to instructions on youtube. Also, since it's a back up key the battery may need replaced. There is a battery in the key fob and possibly in the key itself. If it's the battery it may not need to be reprogrammed. I wouldn't boil it though.
Your problem is the key module on your second key. You have to reprogram it to a dealer.
The gear shift is because your brake pedal switch is faulty. Fix this and it will be normal again.
Good luck.
Ground issues brad, ground issues, all Jags use a cam bus that sends command based on resistance, once the grounds points start deteriorating the cam bus does not the codes correctly, same for doors and several comfort systems. The Spare key does not have the chip or its damaged, you need to replace it, you can't fix the chip itself (it's tiny) so clean the ground points (same issue you get with cold solder joints)
More than likely, the transponder in the spare key isnt working correctly. The key turns in the ignition tumbler because its mechanical. But, my educated guess is the chip in it has lost it's pairing with the receiver in the dash. I had a similar problem with a 2001 XJ8L. Had the keys reprogrammed and it was gravy afterwards. Also, coolant and washer fluid is cheap. Take care of your ride and it'll take care of you.
i had to do this to our car when i replaced the battery, it wasnt paired with either key as it had lost its memory
The coolant is topped up. It’s just a sensor.
awesome video very helpful i have 2001 Jaguar xj8 i'm having problem with accelerating from standing still can anyone help me with the issue?
Looks like my car keys, 1996 Ford Escort. The car is fine but the keys are a lot of trouble.
Greetings from Germany. Hawky.
Ford owned Jaguar in the 90s, they probably used the same key manufacturer
Maybe try taking it to a locksmith to see if they can reprogram the key to the car. Or you may have to buy a new key and have it programed to the car. Good luck with it anyway.
There's no battery inside. There is a passive transponder and yours is broken. A jag dealer can cut you another key using the working key.
have you had your key reprogrammed
Gotta love this "not boring" *guitar related content* 😯
The antenna receives a signal from the transponder in the key they lose their programming take to your local locksmithto have it reprogrammed and it will work fine I a Locksmith and we do it all the time it happens to all car
It's a chip in the key, high magnetism,weather etc. Simple A/B circuit, that is completed with the ki ey it is low-powered. Your shifter interlock is broke. There is a lever that runs through to the engine bay.
Not low powered lol phones non powered.
There might be a bad transponder in that key. Looks like a time for a new car, take advantage of year end sales if you can afford it...
Have you checked the rectifier valve? :-p
I would not worry about the key but would fill the coolant. I have a Jaguar car channel here on RUclips,
Why coolant?
well thats just great
Jag's are beautiful cars.... to look at.
Have you tried programming the key like they do with an x-type of the same year? Open door Turn from 1 to 2 on ignition four times then push button on key then close door I think .. check on youtube. Could also need a new switch behind the lock but I don't know why it would work with one key and not another, that's why I think the rfid chip is the first place to look. There is a youtube of a taxi mechanic saying he has replaced 10 of the key switches recently and it is an easy fix.
The chip in the second key failed. Use the other "original" key until you can get a new one.
i have had a no start no crank intermittently, and then a couple times i've also noticed what my engines cooling was fan running after i turned the key off... turns out the engine is rather quiet and running too, despite the key bing out of the ignition... both issues are cause by a failing ignition switch i reckon
The fan continuing to run when you turn the engine off is a feature. Mine does that too.
YOU PAY EXTRA FOR THE LUXURY, NOT THE LONGEVITY, IT IS MOST LIKELY
THE KEY FOB BATTERY ?
It probably has something to do with the shifter. I dont think it's the factory key. I'll bet the computer is telling the ignition(when using the factory key), that your car IS NOT in park. Try wiggling the shifter in the park position while turning the key. A good mechanic would know. Just call around
In the manual it says something about what each key. Can do a, b, c
Perhaps the computer is stopping the second key from working because its your back key, not supposed to use it all the time. also other problems sounds like your battery is not holding enough charge ?
Did the key get around a strong magnet? Maybe that messed it up.
You love your British stuff mate. :-)
Jaguar ain't British mate lol - was once, but not for a long time.
@Mark Swarbrick They used to be REALLY British, but now the cars are actually mostly made elsewhere, and in fact are not really jags at all. Take a quick look at what they really are and you might be surprised (and dismayed lol)
My first Jag was a brand new X type in 2004 and have driven Jaguar ever since! Never a problem in all these years! Love my 2016 XF but they are neutering the new ones with 4cylinders!
The X type... a ford taurus with new body panels.
You got 99k miles out of feel lucky. I worked with an English man at one time, he told me that their cars were made to be tinkered with to compensate for the high price of gasoline. It gave them something to do besides drive them.
I had the same key issue and a quick programming qith a capable scanner did it
this is gonna sound weird but change the battery for the key. i found that you have to do that yesterday lol
Sounds like he wore down the ignition switch. Had the same problem with my lexus.
With the key that isn't working in the ignition hold the working key as close to the other key in the ignition as possible then try to start it. If it starts then the chip in the non working key is bad
I mean the key fob takes batteries
What numbers activate my cell phone in my 96 Jaguar
Jag. Nuff said.
I dated a girl who's stepdad owned a Jag repair place. He did very well for himself. Very.
Don't put a chevy in it, the problem is electronics, nothing to do with the excellent engine in these cars. Reset the keys and security system, give the locks a service and lube. Jags of this age can go on forever looked after.
Yeah, people confuse the xj8 with the 6 and 12. These don’t have nearly the same kinds of engine issues as those engines. My engine has been reliable. The car is approaching 17 years old. Of course it’s going to have some quirks.
@@Fixologist1 The straight six engines are bullet proof as well. The V12 was always troublesome though - the cooling system was prone to failing and the engine would cook in a few minutes. Happened to an XJS I had, which is why I now have an XJ6.
I loved my JAG,s and had a couple but have now moved on ..sorry :-)
)
Brad... why would you tell us lmao, that you own a Jaguar?!? hahaha
You never mentioned anything about the plastic chain tensioners which are famous for breaking. They must have been replaced before you bought the car.
I love my VDP.
Is 2003 Jaguar electronics still made by Lucas Prince of Darkness?
Either the key RFID has failed, or it needs to re-programmed
it can happen to any car too, my friend's '06 honda forgot both his keys and had to be reprogrammed.
A no start on a Jag is not a problem , it's a solution . ;) LOL.
Poor Jag owners...need to have two of them so when one is in the shop, you have another you can drive... see a lot of these problems with these cars...🥴
The Truth!
Yup - this is how shit post friday turns into scrap yard saturday 🤔
15 years and 3 brand new Jags and never have had a problem.
@@GearGasms then why did you need a new one every 5 years?
@@GearGasms Their reputation for reliability has definitely improved over the last 6 years and Jaguars are without a doubt some of the best looking, most comfortable, most fun to drive vehicles on the road. But if I am buying for reliability, I will go for a Merc any day over buying another Jag.
Don't boil the key. Why do you think that would help?
Check the Date on the Battery. If it's a 1,3 or, 5 year Battery and the times up, Replace it before it gets any Colder. Old or Expired car Batteries never work any better in the Winter. If it's still got life left in it, check the voltage right across the terminals for reference. Next, check with the engine to read the difference when the Alternator is running. Battery should be 12+vdc if it's good. With the Alternator runing it should read at least 2volts higher. 13.5 to 14+vdc. If those are good, you need to get an engine diagnostics module and read the error codes to find the problem. It helps if all of the known bad or disabled sensors are repaired/replaced before testing. That way you won't waste time chasing those down. Since, everything is read by the EMS or Engine Management System. Eliminating known faults will only save time. And, the actual problem will be more obvious or apparent.
Good Luck!🍀
Meant to say, with the Engine running check the Battery again.
Also, the Key Fob probably has a Watch Battery in it. Check that before Boiling.
You’re confusing the fob with the key. Fob works. Key doesn’t. And it obviously isn’t the battery. Engine starts fine with the other key.
I'm not confused at all. Cold weather is a test for batteries. Just like extreme heat tests your AC. So far this year I've seen below 0°F wind chills. If, your battery hasn't reached it's life expectancy? And, you've had to charge it? Your alternator is suspect. It's a simple voltage check with engine running and engine off. Takes 2 minutes to find out. That's easier than being stuck on the side of the road in your pajamas in -0° weather.
The key looks like it probably has a chip in it. You can go online or phone a dealer to find that out. And, why it's not working.
Getting sufficient power to all of your control modules, sensors and, accessories might clear a lot of your error codes. Think of them as alarms instead.
I bought one for $1500 and I spin it in intersections and abandon lots do burnouts ext You got a big these cars up if you babies them they don’t work
I had a 1989 XJS and in the winter damp used to get into the distributor and it wouldn't start, I had to put a bag of desiccant in there when I parked it up for the night then remove it in the morning and that solved it, It was a bit of messing about but these things are to be expected with old cars.
By the way, Brad what is the purpose of the old 10p English coin under the gear selector?
Maybe need a new battery in your key fob?
