SOURCE: The car alarm and key pad will not disarm and the car will not start.

Normal system operation - when the burglar alarm is active, the starter circuit is disabled. Is the battery dead or weak in the keyless remote? Also, is the remote you have been programmed for this vehicle? If the answer is 'yes' to both questions, replace the battery in the remote. Otherwise, place your ignition key in the ignition and turn the key to 'run' (or 'ON") wait 5 minutes, the vehicle should start (if the battery isn't dead).

SOURCE: Can you disable car alarm in 1991 Acura Legend by

If it's a cheap aftermarket alarm, check for a red wire coming off the hot side of your battery with an inline fuse. If it's not, try to locate the alarm "computer" under the driver's side dash or nearby your fuse panel. You'll find a black box with a wiring diagram glued to the side, normally strapped to a wiring harness or other fixed element. If this is the type of alarm you have, you'll need to trace each wire coming from the alarm computer and unclip each fastener that's clipped to your vehicle's factory wiring. The trouble with these types of alarms is that they can get power from a number of sources (stereo, interior lights, etc.). Good luck with this one!

How to determane if my jeep has a after market alarm or a factory?


The factory alarm is tied into your ignition switch. Most newer vehicles have an anti start system incorporated into this in case it is broken into. The alarm will shut the system down and will not allow the vehicle to start. Look under the dash under the driver side and see if you can locate a small box. Should have a serial number barcode on it. If so it has a factory alarm.

How to stop a panic alarm


There are thousands of alarm types out there, the only real way to know for a specific alarm is to look into the owners manual that came with the alarm system.


MOST ALARM SYSTEMS WILL STOP THE ALARM WHEN YOU PUSH EITHER THE LOCK, OR UNLOCK BUTTON.

Some also shut off when the key is put into the ignition and turned on.

On some really secure type model alarms, you may have to find & press the reset button for 5 seconds, or press the button and insert the key. (these switches are sometimes hidden since they can override the alarm)

If it's an aftermarket alarm only type system, you can always find the main power supply to the system, or the fuse and disable it.

If it's a factory system, or one installed to immobilize the ignition/fuel system, then pulling fuses isn't an option as it will disable your ignition on the vehicle.

Most do go off in about 1 minute if left undisturbed, then rearm.

Good luck!

I just found out my car had an alarm system but was disconnected and i connected it and now car wont start even if i disconnect it again


last ditch effort , disconnect the battery and wait 10 minutes and hope your system re sets itself , not knowing what make your car is , makes this hard to answer, or if it was a factory alarm or aftermarket ,,,, If its a factory alarm, you can do this Open the door with the key. (the alarm will sound but ignore that)
Close the doors, put the key in the ignition
Turn everything off that takes power when you got the ignition on.
Turn the key into first position (IIRC) the alarm will go off again, but still ignore that.
Then sit back and relax for exactly 15minutes, without touching anything nor opening any doors.
Then turn off the ignition.
That's it. Your alarm is now disabled.
Start the car and enjoy.

I need to disable my alarm on a 1997 bmw 528i.


Now im not sure since the manual says your model has the same alarm system as the 328i and on the 328i you can remove the module to disable by doing the following. you can unplug the control module. It is located under the glove box. Climb under the dash on the passenger side and remove a few screws on the trim panel under the glove box. Theres a black control module with a green connector. There should be a lock tab on the connector. press the lock tab and pull out the connector. The alarm should now be disabled. But if it has the special transponder key this may not work.
But if the only reason you want to disable it is because of the motion sensor setting of the alarm for no reason there is a solution for this. To disable the motion sensor, hit the lock button to arm, then hit lock button again within four seconds to disable motion sensor. Red light on rearview mirror should flash four times, then pause, then start flashing on regular intervals. this is most likely the reason if your having the issue where the alarm goes off every 20 minutes.
If you want to completely remove it below is a wiring diagram taken from the manual for you alarm system.
this is from the manual its the alarm wiring diagram.

97 bmw 528i factory alarm goes off for no reason


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.
