Hi Rickey,

Looks like you have a couple fuses in front of this one. Here are the wiring diagrams but power goes from the battery to the under hood fuse block above the battery to the Radio fuse, then to the Headlamp fuse, then to the IP Fuse panel which contains the Pass key fuse. Check these two fuses first, then you need to start checking wiring in between these if those are okay.

Start with the wiring diagrams below but the one labeled 3 is the start of the circuit. Then number 2 and the first is just an overview of the system.

Let me know what you find and we can go from there. Thanks
