This happened about two weeks ago. Once I washed the truck, doors and worked again. This time the key-less remote will not work after washing truck. I changed battery on my remote. My remote will not work either. Is there a fuse that relates to key-less entry?

Hello,

There are six fuses that run the system we need to check for power. Here is a guide to help you with that and the fuse location and security system wiring diagrams so you can see how the system works below:

It sounds like the BCM is going out. I would remove the electrical connectors and check for corrosion at the BCM. here is the location. Check out the diagrams (below). Please let us know what you find.
