Q: My alarm key for my car won't work

asked by on

I'm currently at school and my car alarm keeps going off even though I unlocked it.

You may need to shut your door, lock your door again, and then try unlocking it. If that doesn’t work you may need to replace the battery in your remote. Unfortunately, without more information about the vehicle, it will be difficult to provide any additional insight on this issue.
