The keyring is only an antenna with no code involved. The key, IMMO (CAS/EWS), and DME all need to be programmed together if you swap parts between cars.
Assuming that was your fix to the no crank, no start? Currently having the EXACT same symptoms with an E39 manual. Replaced EVERYTHING on the ignition system, including a brand new key from the dealer, and got it working for a couple days. EWS and DME scanned for faults and zero. Im hoping this is my problem cause im exhausting all my options besides tracing the whole harness :(
You removed the ring while the car was already running. The car does not need the ring around the ignition to be connected while the car is running, it's only required to communicate with the correct key which will allow the car to start. Now in you video you switch the car off while the ring was removed already but you were able to start it back up again without the ring connected, this is also normal behavior, once the ignition is turned off, if within 10 seconds you will be able to start the car back up without the ring connected or even the chip in the key, in fact you could start the car essentially with only the key blade with no electronics present, as long as you try to start it again within 10 seconds after turning off the ignition. I believe you did not wait long enough after you turned the ignition off before cranking it again thats why the car started without the ring around the ignition. If you don't believe me you can try it yourself. If you have an after market key that clips together or even if you have the original key that's been cut open, start the car with the key as you normally would then turn off the car, and quickly within 10seconds remove the electronics from the key so that you only have the key blade and you will see the car will start up no problem, but if you wait more than 10 seconds and try and start the car using just the blade it won't crank until the ring senses the correct chip in the which will allow the car to start again
mine is auto transmission. and got Key problem. any solution beside i get a new key? already try bypass from ews car Cranks but no starts. pls help before i have to buy a key
I came in from the store and when I go back to my car it got a no start not crank. The batter is good and I’ve rested the fuses I just haven’t replaced or tested the starter. Should I try this
Hi my friend. Did you experienced any trouble with the alarm, ews or else ? I'm currently having the same problem with my e46 and I'm very tempted to try your technique.
@@waldyxlt hi, thanks for the feedback. Mine is a manual too. I tried your technique yesterday, without success alas. I might have to change the starter.
It has nothing to do with your no crank problem as it works correctly! When you put your key in and the doors were opened I could hear beeping which means immo and code were recognised correctly. By wiggling the cables you accidentally wiggled the whole barrel which wiggeled on the other side the ignition switch were likely your core issue is…
Tengo el mismo problema. Puedo abrir y cerrar con la llave de diamante pero no arranca. Con la llave de plástico si arranca.. Alguna idea de que puede ser? Anillo? Transponder de la llave? Gracias! Buen vídeo
Según he leído, la llave chica o plástica es la llave “Valet” y esa llave tiene chip como la “diamante”. En ese caso puede ser que la llave “diamante” tenga la batería descargada y por eso la antena que mencione en el video no la reconozca.
Good question, the only thing I bypassed on mine was the clutch switch, the key antenna was disconnected and it started without it only after it had started with the replacement key antenna. I didn’t try a “jumper” wire on the key antenna harness. So I don’t know if that could be bypassed.
Apparently those antenna rings are mated to the sensor in a key lm told and to get a new coding and barrel costs 400 bucks in Australia, might have to bite the bullet ahh well
@@billystergiopoulos8025 I simply took a key ring antenna from a parts car that we have and it worked on the car in the video. I believe the key and the EWS are coded alike, and the ring is just there to tell the EWS “yes that’s the correct signal coming form the key”.

I truly hope so, these issues are frustrating!

Absolutely correct. Please consider subscribing.👍🏻

does this apply to auto transmissions?

Is yours a manual one as well?
No automatic
Ok, I think this video may help you sort it out. ruclips.net/video/L1T7u70rog0/видео.html

Hello, I had no issues with the alarm, ews etc at all. Keep in mind this one is a manual.

I had no crank no start noticed a fuse kept popping under the hood followed the o2 sensor wires found a short
Witch fuse?

Hola Alexander, en suyo es manual o automático?
Es manual.
Según he leído, la llave chica o plástica es la llave “Valet” y esa llave tiene chip como la “diamante”. En ese caso puede ser que la llave “diamante” tenga la batería descargada y por eso la antena que mencione en el video no la reconozca.
The problem is simply in the battery. Discharged or too old.
If the battery is discharged - why are the doors locking/unlocking with the remote buttons?
Any ideas on how to bypass the key antenna on a automatic car since with manual you disconnected the clutch?
Good question, the only thing I bypassed on mine was the clutch switch, the key antenna was disconnected and it started without it only after it had started with the replacement key antenna. I didn’t try a “jumper” wire on the key antenna harness. So I don’t know if that could be bypassed.

It was only the reciever ring??
The ring and the clutch switch.
@@waldyxlt do they need to get coded? And they broke just like that or bad recieving and stalling first?
@@E36andE46vlog nothing I did on the video had to be coded. The ring just stopped working. One morning the car wouldn’t crank and that was it.
@@waldyxlt you put in a new ring and it worked again?
Amigo tienes algún whstap no hablo inglés y creo q tengo el mismo problema
Hola, preferiría que platicáramos acá, así todos se benefician de la conversación. Te pregunto, tu automóvil es manual o automatico?
