How to Remove an After Market Car Alarm
by Kim Sarah
After market car alarms are installed after the car has been purchased, and installation often involves the rearrangement or cutting of ignition wires. This, among other things, can result in your car or the alarm malfunctioning. A broken alarm may sound at unwanted times or not at all. For these reasons, it may be best to remove the alarm altogether. The process is fairly routine and can be done by almost any car owner.
Step 1
Raise the hood of your vehicle.
Step 2
Disconnect the negative cable of your vehicle's battery with an adjustable wrench. Loosen the nut holding the cable to the battery by turning it counterclockwise.
Step 3
Remove the plastic panel on the bottom of the drivers side door. Pry it off the door frame with a screwdriver. Press the plastic tabs around the perimeter of the door inward. Pull the panel away from the door frame.
Step 4
Remove the alarm module from the door frame. The alarm module is a small box with an antenna sticking outward on one side. Cut all wires and plastic brackets or zip-ties connecting the alarm to the door with wire cutters. Cut the wires connecting the alarm to the ignition, horn, lights, and power locks (if any). Pull the alarm away from the door frame.
Step 5
Connect the two wires in the door with the two wires stemming from the ignition. Match the color of each wire on the door to the color of the wire from the ignition. Secure the wires together with a wire crimper. Wrap the connection with electrical tape. Repeat this procedure for the wires of the horn, lights, and power locks (if any).
Step 6
Replace the panel on the door frame. Press the panel into the location from which it was removed. It will snap into place.
Step 7
Connect the negative cable to the battery once again. Secure it in place by tightening the nut at the connection clockwise with an adjustable wrench.
