E90 non CAS fob question

Doseddies · 03-13-2016, 07:25 PM

I have looked and looked. So now I flat out ask. Car is 2010 Sedan,does not have Comfort Access. Both keys start and run the car. One Fob died and would not come back with long drives. Bought replacement batteries and snap together cases. Still dead. How do I re establish connection with the car?
Was it dead too long?
Other one is dying. If I open and solder in a new battery will it lose connection also?

Help?

Try and push and hold the fob in for like 30sec to see if it will resync with the car. That is what you would have to do with a new fob
