2001 Blazer Trailblazer

I am having an odd ball issue here. Before anything, I checked all fuses inside the car, and they are all fine. One day my keyless entry stopped working. I thought it was a battery, so I got a new one, swapped it, and bam. Nothing, still not working. I went to reprogram it like I did before, and that doesn't work anymore. I'll do the hold the unlock button, on/off/on/off method and the door locks don't do anything. Now before I start digging further into the car, does anyone have any idea what this could be or where I should look?

 

It is possible that the RKE module has gone bad... I have posted the wiring diagram in the past (if I could find it...). With that, you could test the power and ground to the RKE module to verify that it is getting the appropriate power/ground for it to be able to operate.

 

I am sure the RKE module uses the standard red/black. I will tear into it tomorrow and see what I can find. I tried to do a search, but everything comes up with programming and nothing really of the programming not working.
