Hey guys! I have an 05 Armada SE. Sometimes when we park it after a few minutes the horn beeps and the lights flash like we locked it with key fob but its doing it automatically. It keeps doing it every few minutes. Any had this problem or know what might be causing it or how to solve it. Its freakin annoying!

Thanks,
Tim

Sounds like a bad Keychain Remote to me.

This happened to me. It even opened the windows. Found out that the remote just came out of the washing machine. After letting the remote dry, it stop doing it.
