How to disable alarm on bmw 1998 528i - 1998 BMW 5 Series

Quite often people forget to attach the ground cable that goes under a bell housing bolt , check there first.

Hi it seems like key is not responding. Its been immobilised.
you need to get some one down to get the key to be read by the car. Possibly need the car key reprogram

Check you have not left any wires off or trapped any when putting gearbox back in

Reason I'm even bringing im up is because Ive seen it. Could u possible have a dead battery in your remote?

Disconnect the battery, have the ignition key turned to the "on" position then reconnect the battery.

Your cars Alarm/disabler is on. It's an anti theft device built into CPU. You need BMW or a competent specialty shop to look at it.

I think it's an alarm problem, make sure the alarm is disabled.

if you could disable the factory alarm there would be no point in the factory fitting it.you need to replace the remotes....2...silly question, have you tried new batteries??

disable the hood microswitch. just unplug it. That and the cabin sensor are the most probably reasons the alarm will go off.
Alarms are useless. Totally effin useless. So it goes off.....then whaddya going to do. Shoot someone? Call the police? or listen to it drain the battery over and over again.
But....you can't disable the alarm totally. The bmw engineers have tied it into the main computer. you can however disable the sensors one by one so it doesn't set off the alarm. Hood sensor....Hood sensor....that's the culprit.

I had a 740 il bmw 97 befor it won't start turn the key juste the light in the dach on now tech on bmw had it start but the alarm still on tell the cause of it what can ido to to stop the alarm
