I have a similar problem on my 05 convertable. Picked up a new remote key yesterday which due to a similar problem with the passenger door won't remotely unlock anything. The passenger door won't unloack with the key or toggle switch either, need to pull the inside door handle. BMW Springwood have booked it in for look next week. I seriously hope I'm not hit up with a $500+ bill, I've just spent $600 on the key! |
