I've got a96 2500 It has an aftermarket LOCTRONICS anti theft. I hadthe truck in for service and they pulled the fuse to disable it.I put thefuse back in and now I can't LOCK or UNLOCK the doors Im hoping it just needs to be reprogrammed. LOCTRONICS is out of business and the company that bought their stock is not too helpful. They would rather I buy a new system from them.
BTW The company that did the fuse pulling is to far away to go back too.

Thanks for any help anyone can offer

John
