Hi
So, to start, watch until the end... there is some interesting findings....
This Toyota Rav4 came to me due to the 2 remotes not working... and only one of them would start the car... by pressing the start button with it...
All wireless/keyless entry & start functions were completely inoperative...
Be easy on me, was the first time for me, working on one of this Rav4 keyless systems... but got there in the end...
Follow me on this video to find out what was the problem and how to resolve it.

Like always, thank you for watching!

Very well done, you would put many main dealerships to shame. Tenacity, skill and perseverance combined with thoroughly completing the job to prevent reoccurrence. Well done.

You are a lifesaver! I took my Toyota Vanguard 2010 (Stretch version of the Rav4) for angine and body power wash, and water entered that place (I didn't know). The car would not start, got stuck on the road. My first thought was something entered water in the engine. I was looking forward to a very stressful and hefty repair bill. When I bumped into this video, I fixed it myself. Just opened that same place, removed the cable connectors, and found it waterlogged. Let it dry. did all you did on yours, and just like magic, the car started, and its working fine. All thanks to you.
😊
That's great!
Check and seal the place where the water it getting inside... to prevent it from happening again...
👍👍👍
@@LMAutoRepairs Done that! 👍
👍👍👍
Hello, I have a similar issue with a vanguard as well. How exactly did you solve your issue?
Read my post above. I had pressure washed my car, and water entered at this part of my Vanguard ruclips.net/video/rsfccv93MPM/видео.html . I disconnected them all, let them dry in the sun, reconnected everything, and my car started.
I had the same issue with the same type of car , toyota rav4 three days ago , but my case was with all the entry and start system working but the key does not start the car except if you touch the start button with it , after a health report generated by my launch x431 , there is no dtc at all so i was by my self with that car and no help at all , i dig into the diagnostic and used that function to check the antennas , and find that the front antenna was not working , found either that i can start the car when i put the key on top of the rear seat , so i was able to realize that my front antenna is not working , i told the costumer to buy a new one or i can swap for him the antenna from the rear luggage comp to the front as a temporary fix . Thanks for sharing that
😊

Спасибо большое за видео! Очень помогло! Мы смотрели разъемы под водительским сиденьем, но там всё было нормально. После просмотра вашего видео проверили остальные разъемы и нашли точно такие же с коррозией, как на вашем видео, но с пассажирской стороны. Всё заработало❤❤❤!!! Удачи во всех ваших делах!
Well done Luis . Logical thinking and a successful repair . For me personally one of your better uploads . I work on a bunch of cars that have been in accidents and I am used to seeing this . Not saying that yours was in an accident but water is always a point of consideration . Great job Luis .
😊
Thanks Belux!
👍👍👍
Toyotas reputation is saved...some jiggerer has been at work on that roof rack causing the issue. And Luis drains the swamp!🤣🤣🤣
😅
👍👍👍
Very helpful troubleshooting video. I have same Rav (US version) and had a no start condition. Thanks to you I found I had same issue with water causing corrosion in the connectors on that same junction block. Source was sunroof. Got it to run, but couldn't get any smart fob functions to work. Don't have a high end scan tool, so I had to take it to the dealer. Ended up that the BMC control module was fried. $1400 later, it's all fixed. PS, my misus moans about helping me too! :) Thanks again for capturing this.
😊
LoL
Thank you for watching!
👍👍👍
Top fix again Luis. Good ole misty Albion and careless people keep electronics soaking wet all the time, keeping you busy 😁
😊
Very true...

Always fun to do some car electrics troubleshooting outside when it is raining!
😅
A lot of fun indeed...
👍👍👍
Sunday morning wake and bake is here again. Cheers for the video bro. 👍👍
😊
Nice and warm...
👍👍👍
Had an issue with a leak all the damage was at the front but the leak was at the back, only explanation is parking on a downward slope and water running with gravity along the roof. Confirmed with customer he parks facing down on a hill outside his house and then flat surface at work.
😊
👍👍👍
I love the way you go about solving the problems.
😊
Thanks!
"Door handles". Nope, LM says crusties, kudos to you bro 🍑👍

👍👍👍
Looks a bit like flood damage at some point in the vehicles life ! (And definitely leaking at the rear )Parking sensor kit has been fitted at the dealership just thrown in ( seen this before ) first class Diagnostic skills once again ...enjoyed The Video ...👍
😊
Thank you!
👍👍👍
Must be a Toyota thing, lots of their OEM options are actually dealer-fitted aftermarket kits. My personal favourite is the towbar electric kit for older models where you basically get another indicator flasher and a big fat green LED to literally drill into the dash. I guess it might be because some options are not very popular in Japan and they do not want to develop a more integrated solution for the EU/UK market.
Very good find. You have the patience of a saint. I've seen the same sort of thing a few months after the Handy Pandy car wash types have been cleaning the interior with a jetwash. It looks like the roof bar fittings have been designed by BMW 😁 The question is how far would you go without the visible signs in the roof.
😅
👍👍👍
Good find. Luis can I link this video to the Toyota Owners Club? It will be mainly for educational purposes and you will get more viewers.
😊
Of course you can...
👍👍👍
@@LMAutoRepairs Thank you.
Another example of going the extra mile great fix
😊
👍👍👍
Congratulations. So with a zafira that even im608 pro could not make the remote coded and 3 other old keys also the remote part would not work. What would you do? I was thinking er? When im608 pro said hold key by receiver but never said turn ignition off first. Key in ignition but wants it held by receiver. A call to vauxhall revealed the receiver was behind drivers kick panel
It always rains at your place ! Greetings from sunny Spain.
😅
👍👍👍
Very good explanation, but the best part was when you say! PÕE... PÕE.... PÁRA 🤣....
🤣🤣🤣
@LM Auto Repairs I have the same.l issue my car is not detecting the key. I don't think there is leak in term of water but you recommend to check the driver side lower area to fix this issue ? I really need some help
I would to start with...
Otherwise check the basics... make sure the battery on the key is good, check fuses etc... scan the car and analyse live data...
👍👍👍
well done, tricky fix, water water everywhere 😉👍
😊
👍👍👍
Uma maravilha, tive mesmo problema e resolvi através do vídeo
😊
Porreiro!
Obrigado pelo comentário!
👍👍👍
Sempre um bom trabalho Dr Luis!
Obrigado!

Hi, you suggested replacing the corroded pins, however i have in the past found it very difficult to buy them, where is the best place to buy just the pins?
Some dealers actually sell them... BMW I know they do... try the dealer first, otherwise online...
Thank you for watching and for your comment!
Great find and repair Luis!
Thanks!
👍👍👍
Good evening. I’ve got the same issue as you did but I’ve cleaned all the plugs but still no joy! Can you advise? Awesome video by the way!
You need to carry one investigating...
It is impossible to guess what might be wrong in your case...
👍👍👍
Very good informative video mate. Explained very well 👍
😊
👍👍👍
I have the same problème but i don't kon the places of (antennes)
My key is being detected but when I hold the brakes down and press the button I hear no starter sound or anything turning over and when they spark it from the front it turns over but wont turn on
Another good lesson 👌 👏thanks
😊
👍👍👍
Perfect job
Thanks!
👍👍👍
This shows crearly why the cars with a lot of electronics have a lot of troubles. The manufacturers treat the inside modules like they would be inside of a house, not inside of a car. What i mean is the manufacturers should invest some money to make the connectors and modules inside the habitacle at least splash proof...
😊
👍👍👍
can i ask what is the reason why the key not work my Car is the same problem
Watch the video...
👍👍
good day bro
thank you
شكرا لك

Como sempre um bom trabalho tu fizest doutor luis👌👍

Hi mate I have similar issue on 2021 Isuzu Dmax. Both remotes work fine. But the keyless entry on both doors doesn’t work and when you try to start the car showing key battery dead but I have changed the key battery twice :(
Perhaps the antennas on the car?
Difficult to say...
Give the car a scan and go from there...
👍👍👍
@@LMAutoRepairs hi mate I did no fault code at all 😢 do u know the location in this car for Antena ?
@jackhewitt8614
You should have at least 5 antennas... Well, I am not familiar with that model, but there is definitely more than one...
According to owner manual 2 at each front doors passenger & driver and one under the centre console I look at the under the centre console it look fine no water or corroded plus my remote works for unlock and lock. And also I can remote start the car but the keyless entry won’t work and I have to put the fob on the push start to start the car. Do you know what fuses I should be checking ? Thank you
👏👏👏
😊
👍👍👍
I have a similar issue to to this on 2007 rav4, my keys work perfectly locking wise the buttons on the doors work, the only issue is i have to point the key next to the start button as you have to start the car, both keys have brand new batteries in, any ideas?
Either the key or the antennas on the car...
You need to investigate...
👍👍👍
@LMAutoRepairs thanks, both keys do the exact same thing, do you no the locations for the antenna's
Usually under the carpets front and rear, and boot...
Have you scanned the car?
Yes no codes on the car, it picks up the key to start the car if i hold the key in the rear seat area
OK...
That supports the theory of bad antennas...
Live data might help as well...
You need to find the antennas and see what is wrong with them...
Ahhh you good. But why would you choose maxysis over the im608? Thanks
What do you mean?
They are different tools...
Thank you for watching!
@@LMAutoRepairs thought with the im608 you can do most diagnostic plus key coding
Correct...
But the IM608 is a recent purchase...
I bought the MS908P years ago...
It is all about the 💸...😅
This is a part time for me... lol
I have the same issue with my toyota voxy, I've checked all the connectors and junctions,no corrosion but the car doesn't communicate with the key when i do the test.what might be the problem? please help
A good scanning it probably your best option...
Obviously providing you already made sure that the key fob batteries are OK...
👍👍👍
Great video 😊.
Thanks!
👍👍👍
Perfect
☺️
Thanks!
👍👍👍
wow no ss 318 medal weather part, wow
He figures it out main issue at 25:30
Not quite... that's when I showed it working...
The "figuring out the issue" is way earlier...🤪
👍👍👍
Haha really? Wasnt the issue those plugs that were green from water exposure??
@ThinkTurkey
Yes... but that was sowed at 24:11...
☺️
@@LMAutoRepairsah yes not to mention the water pool in the trunk you discovered which the root cause was from the roof rail bolts - awesome video very helpful, I’m having the same issue and I have taken it to a mechanic and car key fob specialist to no avail. So with this knowledge will take it again in morning to the mechanic lets see how it goes - thanks again mate will update here again tomorrow 🙏😊
Well done !
Thanks!
👍👍👍
Boas Luis sera que me podes indicar de onde mandaste vir a im608 algum site que recomendes? Eu ando a procura mas nao confio nos sites que tenho visto
Eu comprei num revendedor...
Pagas mais um pouco, mas é como dizes, outros sites são difíceis de confiar...
Google ecotune
👍👍👍
@@LMAutoRepairs obrigado eu acho que sei quem sao eu vou dar uma vista de olhos no site dele entao
👍👍👍
The best ever

👍👍👍
Hi, have you done BSI clone with IM608? I am thinking of buying this device. Regards.
No...
Did programmed a some keys though...
👍👍👍
@@LMAutoRepairs Thank you for your answer. Regards. :)
Thank you so much 💟
😊
Thank you for watching!
👍👍👍
Awesome
Thanks!
😊
Thank god you didn't have to reprogram the keys as it's near impossible what a stupid procedure you have to go through it's crazy to have to program the keys
😊
👍👍👍
I've the same fault code on my rav4 but my car won't start I've checked everything you have would you have any idea what it could be
Have you scanned the car?
Have you checked, fuses etc?
👍👍👍
Yes the only code I'm getting is b2799 and have checked all fuses
Check grounds...
Chassis and signal grounds...
👍👍👍
Will do and thanks what the best place to get wiring diagrams for cars
There is different places... depends on the manufacturer as well... I use HGS as my to go place... bug even there, there is missing stuff on some cars...
👍👍👍
Very nice
Thanks!
What’s up with these dealers not have service appointments? I have a new BMW with less than 400 miles that has a mad front end wobble and I was given the same 3 week nonsense , They said they sold most of their loaner fleet which was normally 40 to 50 cars . Unreal.
😳
Super
😊
Thanks!
👍👍👍
Where did you learn your trade I'm curious to know
This is part time for me...
😊
👍👍👍
@@LMAutoRepairs you are very good at what you do. I'm a 32 year old qualified mechanic I usually do clutches gearboxes, bearings, timing belts/ chains. But want to get more into the electrical I'm struggling to find where to start.
@@thebiker2655
I learned most of it as I go along...
A lot is common sense, and think and understand how it works, to then attempt to fix it...
I have no qualifications at all on any of it...
But I love the fault finding and repairs of this type of stuff... which I do on my free time...
👍
I only follow a handful of channels on RUclips you come to the top of my list. I can tell you have a passion for what you do keep up the good work. Best be said keep your hands dirt. :)

I working on the same fault on 2008 Highlander hybrid. The remote not working,I changed remote battery but still not working,it can’t start the car if I use remote to touch the knob it doesn’t say anything, I do auto scan the machine communicate only smart unit and it gives me dis faults code b2289/b2784/b278A. Pls I need your help to solve this issue
Hi It looks like you have a wiring issue...
Check the antenna coil and communication lines between the power source control ecu and the transponder key ecu...
Obviously check fuses, power and grounds first...
👍👍👍
@@LMAutoRepairs let me know power source ecu location and antenna coil location please
@@LMAutoRepairs I check all fuses and earth everything is fine
@@LMAutoRepairs kindly help me to solve this fault code b1008 on Honda CR-V 2010
B codes are usually for communication issues... check power and grounds of the affected module, if OK, check communication lines...
👍👍👍
That car looks like a hi spec model so why didn't he pay extra for the racks to be installed from the dealership it just doesn't make sense
🤷♂️
Who knows...
👍👍👍
Good. Job 🇲🇽🇲🇽🇺🇸🇺🇸
Thanks!
👍👍👍
Perfect 👍
Thanks!
👍👍👍
I don't get no key detected but won't even try to start/crank
That sounds like a different problem...
Have you tried to scan the car?
👍👍👍
@@LMAutoRepairs Ok, i solved it. seems like even tho battery seems to be good, doors open, radio works and all ,the instrument lightning is good etc. The Security system didin't go off, i changed the battery and BOOM, started right off. no issues now. changed batteris on the keys, no affect but i had some issues with the battery because the fuel heater didin't run, wasn't heating. NO other signs of dead battery. Usually when battery not good the car cranks but no start. This was what was confusing me.
and yeah, outside was like at least -20 degress celcius.
Low battery can cause all sort of issues on different cars...
👍👍👍
Please change the battery in the keys to solve the problem.
😅
Not in this case...
Have got the same model car, the key did same thing all i did was replaced the battery, but i never had water coming inside the car.
you probably have radio receiver issues, powers, ground, communication line needs to be checked, before you replaced the receiver
What receiver you are talking about?
Well on Toyota's smartkey systems, the key normally replies back to the vehicle through the radio receiver module, then the receiver module sends key info to the smartkey ecu, the smartkey ecu talks to the key through antennas or oscillators, so in your case the "no key detected "massage on the cluster, and you have to bring the key closer to the push button to start the vehicle. That's typical key info was not reach to the smartkey ecu,
Radio receiver or door control receiver is the same ecu that monitors tire pressures TPMS
Watch the video... 😉
I'm not saying that you're wrong, I watched already you found corroded pins at the connector Wright? Good 👍👍, my point here was explain that Toyota's smartkey system is one of the most complex system ever, because they split their system to so many modules, certification ecu, power source ecu, body control ecu, id box. Steering lock ecu, radio receiver ecu, oscillators, toyota and lexus has these modules on their smartkey system
Woow good job
☺️
Thanks!
👍👍👍
The water in plugs is a know problem on a lot Toyotas . They make cut corner engineering since 2005 . Failing fuel injector is another one they used 3 us$ injectors on cars to cut cost .
😅

Still raining 🌧️
Indeed...
👍👍👍
How about just buy a car with a physical key, (if it’s not broke don’t fix it). Keyless car is the most stupidest idea.
yawn
