Call the police (non emergency), 2. Leave a note, 3. Check your local laws
Last night, in the middle of the night, a car alarm went off right in front of my house. Then it went off again 10 minutes later. And it kept going off, for more than an hour.
Here are a few things you can do when a car alarm is going off all night.
Call the Police
The police have a non emergency dispatcher, so you don?t have to call 911. Easiest way is to just use Google Maps to find a local police department and call that number.
I called my local police department and was immediately connected with a dispatcher. They took my address and phone number and the license plate of the car. They said they would send someone out. When the police car gets there, they can run the plates and call the person.
Leave a Note
A faulty car alarm can be caused by a bad remote, by a bad ground connection, a lot of different things. But the person might not even know they have a problem.
Leave a nice note explaining what happened at what time.
If you can find the owner, and you still can?t get the car alarm to go off by just unlocking and locking the vehicle, there a bunch of other things you can try.
Starting the car. Pulling the fuse. Disconnecting the battery terminal.

Check your City Ordinances
Some cities have laws related to how often and loud alarms are. Check your local ordinances. Your neighborhood also might have ordinances, so check with your HOA as well.
