I have taken my car to the dealership twice for this and the problem went undiagnosed I was told I just needed a new key. Until i took it to another dealer ship which told me what it was the SKIM Module breaking down 3 times in the course of a year over the same thing is a problem and Daimler Crysler will hear about this, they have already reimbursed me once.

#13 of 20 skim module 2000 wj grand cherokee - reset computer by alby3

well i had the security key light come on and stay on (not flashing). sometimes it went out but it was on more than off. but my 2000 grand cherokee ran fine. however, it died on me 2 or 3 times over a week and 1/2. but always started right back up after i came to a stop and put in park and restarted.
then a week or two into it the guages all went dead, and all the dash lights came on. but the wj was still running fine. the guages would bounce on and off but usually stay on. then i realized it was happening when the temperature went below say 45 degrees. it happend alot then, but she still ran fine... the key light was coming on almost everytime but the guages seem to only bounce around when the outside temperature was under 45 degrees or so....
got to be a ground.... right??? well i undid the battery terminals and cleaned them even thought they looked good and left the battery unplugged for 20 minutes. i read this may reset the computer. did not expect much. but that was two days ago and i have not had a problem since. and the temperature was in the 30's. i am still skeptical but it is working great since i cleaned the terminals and left it unplugged to rest the computer.
so we will see

I have a similar problem with a 2011 JGC. The hands free function on one key was intermittent, I took it in and they gave me a new key where the hands free didn't work at all. Now the dealer says they need to replace the WIN module. I am 100% convinced these guys are clueless. It sopunds like they are just Easter egging the problem changing parts until something works.

I have a 2001 jeep grand cherokee. I am currently having problems getting it started. It will start for 3-5 seconds and stall out. I checked the fuel rail and Im getting plenty amounts of gas. However on rare occasion it starts up, my gauges and sometimes windows and door locks dont work. Although my dash lights do. I checked for a faulty instrument cluster and a bad ground... not the problem. Oh and the security light is on! Any insight please? Thanks

I have the same Jeep and same problem! Please post how you resolved this and I will do the same. I am re-trying reset power now. Code reader says I have "no sentry key" and immobilizer Module" message. I have three keys and two worked. The third would unlock but only start for a few seconds. I have previously replaced lock mechanism and ignition switch. Both keys worke since June but it now sits in driveway. I hate having to tow it to dealer if I can resolve where it sits.

I just went out to my wonderful reliable jeep and disconected the battery, (again) and removed the coolant resevoir tank, removed the 3 connectors to the PCM and the two above attached to the firewall. I sprayed all pins with electronic contact cleaner, and blew out everything with compressed air. Re-attached everything and turned key on I realized I had gauge readings. So I tried starting and it started right up. I don't know if it was the connector cleaning/reseat or battery disconnect. I did re-set battery last week with no help. I am probably going to send next update from side of the road somewhere.....wish me luck.

how did everything work out for you? the garage is running full diagnostics on it, but i too believe its something to do with the pcm.

I had the same issues with my 2001 Jeep Grand Cherokee about 2 months ago. In the end it was the PCM.
Problem started with gauges not working. Then starting/stalling issue. No a/c, windows occasionally would not work. After researching a lot of forums and blogs I tried several things. Cleaned battery terminals. Tested several modules for a short (window, MIC etc..). I had 2 problem codes, P1686 (no SKIM bus) and P1687 (no MIC bus).
The PCM is expensive. I was quoted $700.00 for a new one, not counting labor. The PCM has to be programmed to your vehicle but, this doesn't have to be done by the dealer like they want you to think. I found a company out of FL that sells refurbished and programmed PCM's. Allcomputerresorces.com. My jeep has been running fine since I replaced it a month ago. It was very easy to replace.
