Recode them all again and with each key, make sure the immobilizer light blinks a couple of times then goes out, then pull the key out and put the next one in and turn ignition on.
See if single key, no matter what order you adapt them in, makes the immobilizer light flash instead of blink twice then go out. If so, said key has some "isuses". Keeping the other keys in the passenger seat is fine.
Also, you by chance, after adapting them, had them sharing a keyring when trying to start the engine. 2 valid keys on the same keyring can confuse the immobilizer system... engine will start but light will flash.
Rather than starting a new topic, I did a search and came up with a similar situation.
2002.5 Jetta 1.8t with Immob3
I have two keys that came with the car. I recently purchased a key from Ebay, and making sure that the part numbers matched - I tried to match it to the Immob3 using a Vag-Com and the instructions on the ross-tech website "Immo3-key-matching.html" page. The key showed a value "1" in field 3 of group 22.
The new key, no matter what order I adapt them in, makes the immobilizer light flash rather than blink and go out. If we try to adapt the new key last, the other two keys work fine and when we read the value in Channel 21, it only shows two keys were matched. The funny thing is that it still starts the car...but the indicator light flashes. It throws the "Incorrect key programming" DTC.
So based on the information given in the post above, my key has "issues." What are these issues? Can they be fixed? Can anyone offer any suggestions?
