Subaru Car Alarm Won’t Stop? Here’s How to Turn It Off!

If you own a Subaru car and are facing the irritating problem of your car alarm going off unnecessarily, you are not alone. This issue is something that many Subaru car owners struggle with. Fortunately, there are ways to turn off your Subaru car alarm quickly and efficiently.

Here’s a step-by-step guide to help you turn off your Subaru car alarm.

1. Use Your Key Fob

The key fob is the most convenient and effortless way to turn off your Subaru car alarm. All you need to do is press the unlock button on the key fob, and the alarm will stop ringing. Make sure that you are within the range of the car before attempting this method. If the key fob doesn’t seem to be working, try replacing the battery.

2. Use the Ignition

If using the key fob fails, you can try turning on the ignition of the car. Insert the key into the ignition and turn it to the "on" position. This action should disarm the alarm. If the alarm persists, try cycling the ignition key on and off several times until the alarm stops.

3. Disconnect the Car Battery

If the first two methods fail, you can always fall back on this one. Disconnecting the car battery will stop the power supply to the alarm, thereby stopping the alarm from ringing. However, this method should be your last resort, as it may reset some of the car settings—plus, it is also inconvenient.
