I read other people having this problem. My alarm goes off, everytime I arm it. Putting the key in the door does not shut the alarm off. I looked for that sensor located within the door panel. It's broken (not sure how, the clip was cracked). I'm assuming this is my problem. Where am i able to buy this part, or even it's correct name?

Also, my keyless entry randomly stopped working. I did replace my battery, not sure if that would cause this problem (it's stock alarm/keyless).

Thanks

 

The Sensor/Switch in the door is a dealer item ... They can look it up for you
Intermittant key fob could be bad weak battery or a cracked PCB in the fob. bad/Dirty buttons
