Programming the keyless entry on your BMW key fob only takes a few minutes, so drivers will be back on the Woodland Hills roads in no time. There are 2 basic methods depending on whether you already have a working key and are looking to program additional keys or if you are starting from scratch and do not have a working key. Enter your BMW vehicle with the working key fob and the additional fobs that you wish to program. Make sure that the doors and windows are closed. Insert the original working key into the vehicle’s ignition and turn it position 1. The car’s dash lights and accessories should light up.

I've got a question hopefully somebody can give me some good advice, better than Hyde Park auto. I've got a 05 e90 320d as my secondary vehicle. I lost the spare key a while back and never bothered getting a new one. Now this weekend I misplaced the other and am still looking for it . I hope I still find it however I understand that if I do not find it soon I will need to have the car towed to BMW and by murphys law I will probably find the key afterwards.
I spoke to someone at BMW, i was told that the replacement keyfob is R1300 if you have one key and R4000 - 6000 if you have lost both. My main questions are, can the keys be programmed locally or do they need to be ordered from Germany. I was told the keys can be programmed locally but the locks need to be changed, why ?
Online sources indicate that the laser cut the key thing that slides out of the keyfob used for opening the boot when there is no battery power needs to come from Germany.
Anybody else been through this process with a e81,e82,e87 or e90,e91,e92 that can shed some light ?
