Key Fob/door remote lock problem

My 2000 Cherokee's (one and only) key fob/door remote lock system has been acting up lately......Yes!, I have replaced the batteries in the Key fob!

In fact, I'm a electronics tech, and I've given the key fob the "Once over" to see if there is something loose, or bad on it.....and without taking it too far...I see nothing wrong.

The problem is that the whole remote/system will just stop working......then hours, days, or a week later...POOF! it's back!

I thought it was a bad set of batteries, or a loose connection somewhere in the key fob...but I've been unable to track it down.

Anyone have any Idea where/what to look on the vehicle side of things?
I'm not even sure what/where the radio signal goes to/comes from...ECM????

Is there a way to program another key fob at home? Or am I looking at a dealer only situation?

Thanks!

key fob programming is dealer only

most likely you just need a new remote. dealer programming only.....RKE unit is in the dome light.

Check the connections at the RKE unit for corrosion.

I have had this happen a couple times on the wifes van.....

Check your lock switches to they could be going bad causing the RKE to not work intermittently
