2nd Gen Non-Engine/Transmission Alarm System Problems

[HookMeUp]

This has been going on for the last couple of weeks. When I unlock my truck with the key fob after sitting all day at work the alarm will go off. I only shut it off by pressing the panic alarm twice on the key fob. Why does tha alarm keep going off?

I assume you're referring to the OEM theft-deterrent system and not an overlaid system such as a Lojack prevent. A first thing to check is the battery in the remote (really) since a nearly exhausted battery might erroneously set the system rather than disarm it (I've seen this alot). Much like when your calculator or watch become hard to read - battery time!! I would do this beforemoving on to troubleshooting the host system itself.

Been away for awhile. I changed batteries and still havr the same issue. Anyone have any idea what I need to check? Or at least a trouble shooting guide.
