Disarming E36 Alarm/immobiliser without remote
After changing the battery on my E36 cabrio 1997 the alarm was activated, but having no remote key for the car I turned to the internet in order to get the necessary instructions for disarming. I searched for many hours until, finally, i found instructions for disarming for later BMWs-but it worked for me so it may help others to know the procedure.
Very simple. Firstly open both doors and boot lid. Turn ign key fully on to last position, prior to starting, and disconnect battery. Wait for 11mins, but do not close doors or alter position of key. Reconnect battery strap and leave vehicle for a further 15mins so system can reset. After 15 mins have elapsed turn the key further onwards in order to start engine. Leave running for a few secs, then off. Hey presto,alarm disarmed.
I have read quite a lot of well intentioned articles about disarming the E36 alarm which has included- removing glove boxes,isolating alarms, grounding pink wires, pulling out wiring harnesses...lets hope this contribution helps someone avoid a lot of unnecessary hastle.
