Ford Repair: power lock and alarm system, ford explorer sport trac, ford explorer sport

Question
hello i have a 02 ford explorer sport trac and my problem is my powerlock doesent work my keyless doesent work and also my keyless entry pad dosent work what could be the problem.?  

Answer
Hello Bert, it could possibly be the door lock actuator on the driver frt door or the module that controls the keyless entry or both. There could possibly have a blown fuse on a circuit in the fuse box. That is where I would start looking with diagnostics 1st. Thanks Tony
