How to Disconnect a Factory Alarm

If the sensitivity of your car alarm bothers you or your neighbors, or you simply want to install an aftermarket alarm, you need to disconnect the factory alarm. Fortunately, you don't have to struggle with the alarm wiring to disconnect it. In fact, the simple process only takes a few minutes to complete.

Things You'll Need

• Ignition key

Instructions

1. Find the override button or toggle underneath the dash. All alarms have an override option that's found on the alarm box, close to the steering column. Older model vehicles typically have a toggle switch, and newer vehicles have a button that's either black or red.

2. Override the alarm. Insert the ignition key and start the vehicle. Either flip the toggle switch in the opposite direction or push and hold the override button until the alarm beeps once. The LED light on the dash stays on instead of flashing when the alarm is disabled.

3. Pull the fuse to disconnect the alarm. Find the fuse box -- usually located under the driver's side dash -- and take the plastic cover off. Find the fuse labeled "alarm" and remove it. If the fuses aren't labeled, look at the fuse diagram on the plastic cover to find the alarm fuse.
