Hey, a friend of mine has a 2000 grand cherokee, and he had new keys cut for it. They will start the jeep, but it turns right off. The original key still works. I know some keys have a chip in them, but this original looks like a regular key! Please help!!
He probably has the chip in it. My chip key head looks very similar to a "normal" key with a rubber head.
You can get it programmed at your local dealer. Some lock smiths can do it, but you have to have at least 2 programmed keys to program another one (at least that is how it is at one of my local lock smiths).
BTW- the shutting down is how the chip keys are supposed to work... starting and then shutting down after a few seconds...

He needs a chipped key. Most locksmith shops can cut and program them cheaper than a dealer. I never needed two keys at a locksmith. If you already have two good keys, you can program a third key yourself, no need to pay a locksmith.
Also, your friend may get the check engine light soon. The computer stores the info showing that a bad key was tried. At least mine did after a new chip key I tried did not take the programming correctly. If the light does show up, you can reset it by disconnecting the battery for a few minutes.
