2000 Jeep GC security key problem

The key icon started coming on the dash and it would start then die within two secs. So we went to a locksmith and got a new key and also had the two old keys reprogrammed. Worked good for about three weeks then started doing it again. Now this is an intermittent problem if one key does'nt work I try another one, sometimes that works or I have to leave it sit for about an hour to restart it. Another thing that works sometimes is disconnecting the battery and another time I pushed lock and unlock on the fob and turned the ignition on and off a few times and it worked. This problem is so sparatic that I have no idea what needs to be replaced or fixed. So this problem is the key security icon on the dash thinking that it is the wrong key or something and will start and die if you start within 2 secs. If you turn the key to acc. and the icon flashes it will die. Please Help!!

You need to replace the SKIM module and have it programmed. It needs to be programmed to the PCM with the VIN and the keys all have to be programmed to the module. I don't think aftermarket scanners are capable of all that is involved so you may have to go to the dealer to get it done. I hope this helps.

Engine dies while driving


Faulty transponder antannae at the ignition switch if the car is equipped with a transponder key. Have the security module looked at if the antannae at the ignition is good. If it is the security module a dealer will have to program your keys to the new module. If you know a good locksmith with a tko or other programmer you might be able to save some money over having a dealer install it.

If your jeep is not equipped with a transponder then look into the ignition and fuel system. The problem you described however is common with transponder issues though.

WHAT DOES THE KEY ICON ON DASH MEAN? MY CAR IS STALLING DOES THIS HAVE ANYTHING TO DO WITH THE KEY ICON. 2000 JEEP CHEROKEE LIMITED


The symbols should be explained in your owners manual. The symbol could mean that the key you are using is not recognized by the controller as being the correct key. I think this would not allow the vehicle to start at all. Are you using a key that is a copy obtained from anywhere besides a Jeep dealer? The keys have a chip in them that must be programmed by the dealer. If you are using the correct key, I would have the SKIM module checked.

My Grand cherokee is not starting


If anyone has this problem also where you start your Jeep and it dies in about 2 seconds and the key symbol lights up on your dash I can help. I had this problem yesterday after jumping the battery, I had the correct key but it wouldn't read it. I had a locksmith come out and if you take off the steering column plastic there's a small black module in the column behind the key switch. Unplug that module for 5 minutes and it will reset. My Jeep started up right after. You MUST have the correct key though, mine is gray not sure about other years.

Lock all the doors unlock the doors with the key because the security system thinks its being stolen and it shuts off the injectors
