Hi, new to the forum and was hoping someone might have some experience with Ford Security Systems. I have a 1999 F-150 lariat 4x4, great truck, just had a few minor problems needing reapir. I removed the instrument cluster and radion to repair displays that were out and disconnected the battery. Fixes on displays worked out great after battery was reconnected, but now my security system if giving me fits. I have the stock Ford system with keyless entry and it has a dealer add on of a siren, valet button and red led on dash. Every time I open the door locked or unlocked the siren goes off and the only way i can stop it is to cycle the key (will not start) and push the valet button. It is fine until I shut off the car, about 30 seconds later if I open the door starts all over again.

Anyone know of any possible fixes, can I remove the system withoout loosing keyless entry or rendering the vehicle inoperable? Appreciate any help you can provide and thanks for a great forum

 

Never heard of this one, - your best bet would be to email or PM a moderator on this site and have your thread moved to electrical. Sculley could most likely help you out over there.
