My alarm will randomly start going off after I manually lock and shut my door, and it wont stop until I unlock my door with the key.
Also, my door ajar light is on everytime I start my vehicle, all doors are shut.
Do you

Hello,

This sounds like the door latch on the drivers door might be worn out and needs replacement or you can see if the micro switch (pin switch) can be repaired or adjusted. The security system thinks the door is open or opened unexpectedly. Here are instructions on how to replace the latch check the pin switch first. Check out the diagrams (below). Please let us know what happens.
