How to Stop a Car Alarmby Alexis Lawrence
Most cars with car alarms come with a key fob that is used to lock and unlock the car doors from a distance and also to silence the alarm when it goes off. Key fobs can fail to turn off the alarm from time to time. If your key fob isn't working correctly, it's probably time to change the battery. But until you get your fob working, there are a few ways to stop most car alarms without the fob.
Unlock the driver's side door. On vehicles with factory alarms, unlocking the driver's side door with the key usually shuts off the alarm. If the door is already unlocked, lock the door and then unlock it again with the key.
Start the car. Nearly all car alarms automatically shut off once the key is used to turn the ignition.
Locate the alarm fuse. The fuse for the alarm is either in a fuse box on the steering column or in one of the fuse boxes under the hood. The vehicle's owner's manual can help you locate the fuse for the alarm system. If the alarm was installed aftermarket, the fuse won't be labeled and you will have to make your best guess.
Pull the fuse with pliers. If you pull the wrong one, don't worry. It won't do any harm to your car. Just replace it and keep pulling fuses until the alarm goes off. Remember, once you have pulled the fuse, your car alarm will not work at all until you reattach the fuse.
Disconnect a battery cable. If you don't need to drive the car, you can't locate the fuse and the alarm won't stop, disconnecting the battery is a good way to reboot your car's system. This should reset the alarm system, so when you reconnect the battery, the alarm should be off.
