I need some help for my dads e60 keys, its the diamond shape key for 2005 model , one of them is not working but before i got a chance he opened up the key and seen a battery inside, i presumed it should not be changed? i can try change it but i dont think its the issue, whats the re initialising procedure for these keys? any advice please
id be curious to hear the answer to this also as i have a dead key on the m5 that id like to get up and running again...seems to be a dead battery ... theres a few videos on youtube of how to tune them back to the car once you replace batteryQuote:
