Last week the security system cluster light start to stay on everytime that I drive the truck and the key remote buttons stop to work. Tonight my wife take the truck to go at the mall and when she comeback in the parking lots to drive the truck she open the door and the horn and lights start to flash, she start the truck and the alarm still flash the light and sound the horn, she try to push the panic button, lock unlock the door nothing work to stop the alarm. after about 15 minutes of ALARM PARTY with the engine running the alarm stop, but as soon as she unlock the door manualy (the button stop to work in the truck to) the alarm start again. Is anybody already have this problem and whats going on with that security system. Did somebody have a way to fix that thing...........The truck is a 2006 megacab.

Thanks!!!

 

Have you replaced the batteries in the key fob?

 

Yes and I try my other key to......

 

I want to remember it being an issue with the key fob...but its been a long time since I read that...

Have you tried disconnecting the batteries for a few minutes, sort of a soft reset?

 

try cleaning your battery posts. Seen some weird stuff happen with bad contacts!
