Car alarms are a smart way to warn thieves trying to break into a car. However, the high-pitched sound can be irritating and embarrassing if the alarm doesn’t function accurately.
Are you having trouble with your car alarm? Won’t it turn off? There are different ways to turn off a car alarm including easy ways and more complicated ones.
Using the car key or the key fob: Easy ways to turn off a car alarm
The quickest way to turn off car alarm is by using the car key or the key fob. Here is how to do it:
- Unlock and lock the door using the car key. The car alarm might immediately turn off when you put the key into the door lock, unlock it, lock it and unlock it again. Since your car is opened using the right key, this will transmit a signal to the alarm to turn it off. If the alarm does not turn off, lock the door and unlock it again.
- Use a similar procedure to the one outlined above but with the key fob. Do it when you are near to the car, close enough for the key fob to reach it. Press the unlock button, then the lock button. This will also send a signal to the alarm to turn it off. If the key fob doesn’t work, the batteries might need replacing.
- Avoid pressing the panic button. The panic button is the orange or yellow button on the key fob. Panic buttons turn on the alarm and lights. The panic mode will stop when you press the panic button again.
- If the car alarm is still on, start the car. This will send signals for it to turn off. However, some cars do not start while the alarm is sounding.
- Check the user’s manual for important instructions for your specific model of car and car alarm system.
How to turn off a car alarm: Take the fuse out
The car alarm’s fuse is usually placed throughout the car for different electrical components. Many of the newest car models have more than one fuse.
- To locate the fuse that powers the alarm, refer to the vehicle’s manual. It might be at the engine bay or in the car’s cabin. Removing the fuse in the cabin is quite complicated. Be careful when doing it as you might affect other important wirings.
- Know the fuse that powers the alarm. Refer to the diagram in the manual or in the cover.
- Once you have identified the fuse, take it out using pliers designed for car fuses. The alarm must be turned off immediately once the fuse is removed.
- Replace the fuse and check to see if the alarm starts again. If it starts again, you might need professional help to repair the alarm or you can try checking other factors such as the car’s electronic control unit or key fob.
How to turn off a car alarm: Detach the battery
Use safety gear when using this method. It might produce sparks, so you should wear a protective eye mask and gloves, etc.
- Find the vehicle’s battery. It is usually found at the trunk and is covered with a carpeted piece of wood. Use the owner’s manual to locate the battery; it is usually in the engine bay.
- Identify the negative terminal. It is usually connected to the thick black cable that links it to the car’s body. It has a NEG or (-) symbol. Then disconnect the battery wire from this negative terminal using a pair of pliers. Do not remove the nut; just loosen it enough to slide it off the cable.
- Remove any backup battery that would cause the alarm to keep sounding even when the main battery is removed. Most factory alarm systems do not have backup battery; refer to the manual to see if your alarm has one.
- Wait for the computer to reset. It usually takes up to one hour depending on the model of car. Do not force resetting the car this might cause you to lose the radio’s station presets.
- Attach the battery back. Connect the negative terminal to the battery and tighten the nut. Make sure it does not wobble otherwise the car might shut off while you are driving.
A faulty car alarm is inconvenient but you can repair it by yourself. The above-mentioned methods are easy to follow. If none of them work, get your alarm or car checked by a professional.
