Hi all! I had a problem.. Yesterday, my battery was flat, and today I replace it with new battery. At the moment I connected the new battery, the alarm started sounding. I am able to start the engine. According to the manual, I have to deactivate the alarm before start the engine. I've tried to follow the procedure in the manual to deactivate the alarm (wait up to 15 minutes until the LED stops blinking, but it doesn't work). So what should I do. I do not have the small key (emergency) to stop the alarm. Mine is E36 1996. Thanks for your help....
