At wits end with a dealership (skim module/drb3 issue)
So let me lay it out as best I can and hopefully you guys can help.
I have a 2000 Grand Cherokee and in July I went on a work trip for roughly a month.I came back from the trip and found out someone had broken into my office and took my keys. They didn't take my vehicle, just the keys. Problem is that I only had one key for the vehicle. I call the dealership and get a tow set up to get a new key cut and reprogrammed since it has the skim unit. First line I got from the dealership was " the skim module is so old that it can't communicate with the key". So they tell me I have to buy a new skim module. The total for the work jumped from 160 to a little under 500.

Then after another week of them having my vehicle apparently the skim module they ordered didn't work so they had to order another one. So tack on another week waiting for the second skim module to arrive. Now as of this week the issue is that their drbiii tool doesn't work and they are trying to borrow one from another dealership. They service shop manager said if they can't borrow the tool from the other dealership that I should just have it towed to that dealership nearly an hour away for them to do the service. This doesn't sit well with me because it's going to tack on another 150 bucks just to do a job that they couldn't get done in nearly a month.

My question is what options do I have? Buying a new vehicle isn't an option right now. I have read on other forums that you can disconnect the skim module and reset the pcm and just run it without a skim module. Which at this point I have no problem with because I'm not worried about someone stealing a 20 year old Grand Cherokee.

Any help you guys can provide is greatly appreciated.

You can’t just disconnect the pcm. There are companies you can buy a pcm from that say you can run the vehicle without a skim. I bought one and used it without the skim and it worked when I had it in there, but in the process of chasing my issue, which wound up being something else, I put the old pcm back in and have been driving it with that. Some of the people here that know more than me about these vehicles say the non skim pcm’s wont work.

Good luck.

Step one: You can get them to cut a new key based on the vehicle key code. They can look that code up. Otherwise, you can buy a new ignition switch which will come with a key.

After that you could get a key programmer and program it yourself. Some cheap Asian knock-off key programmers are flaky at best but some of them work great. I guess I got lucky. I believe some automotive locksmiths also have key programming gadgets.

The caveat here is I can't remember if you need at least one working key to make another. I don't think so though. I believe that's only necessary if you are trying to use the new key programming feature of the vehicle itself.

a good locksmith will have the tool to insert in to the lock and read/decode the key profile, then just cut the new key and program in with something like a Smart Pro.
you don't need any original keys as the programing clears the memory when you program a new key into the skim, that's why you have to have all the keys with you when having anything done to the skim module.

Thanks for the help guys I just got a call from the dealership saying they just got the drb tool and are starting to work on it. Hopefully I'll have some good news tonight or tomorrow. They did already cut the new key but I guess there's an issue with
1.the key talking to the skim
2.the skim talking to the pcm

Hopefully I won't have to tow the thing back to my house and figure out a different way to get this thing to work.
