Mine is an 06.
I have both original remote keys and wanted a third water proof non remote key that would unlock, start and run the CRD. I bought one of these from this vendor and you can buy ths key for $6.87 and free shipping

It will unlock the doors that were locked by the fob and NO ALARM SOUNDS and it will start the engine and allow it to be driven. I tried the key before programming it but didn't try unlocking and the engine would start but shut off in a few seconds like it's supposed to
One good reason to getting a chipped key is that it's waterproof

I took it in the ocean swimming several times and use it when washing the jeep.
Here's a uncut fob for only $59.98

Non evic vehicles, at least my 06, you can not program how the locks preform, that requires the evic that I don't have.
I think I remember reading that once a key is programmed to that car it can't be used in another but I'm not certain
