They are all 4 button (lock, unlock, panic, and rear glass).
Also, some locksmiths will be able to program keys as well. You may want to give one a call and see what they can do (they are considerably cheaper than the dealership).
I have 2006 GC Laredo with 3 button key. lock, unlock, rear glass - NO PANIC. Part number below.
A locksmith can clone a current key - the car recognises it the same as the key it was copied from. I had a locksmith successfully do this - it unlocked and started the car - but it didn't de-activate the alarm so it was useless. A dealer codes a new key to the car computer - the car recognises it as a different but valid key. So if you use a locksmith key as a 2nd key to program a 3rd key it wont work because the car only sees 1 original key. I was also told that you can only have a certain number of keys programmed to the car computer before you need to replace the car computer. i.e. every time a key is coded it takes a slot and there's a limited number of slots.
It would be good to start a thread of valid part numbers for keys as the part number on my key is discontinued. I was told by a sympathetic dealer employee to buy my keys online. have them cut at a locksmith, and bring them to the dealer to be coded - the had exorbitant fees for each step. By doing this I only had to pay the exorbitant fee for the coding but he said it's no harder to code 2 extra keys than one - so they should code to keys for same price as one.
My key Part Number# 56038770AH. I have seen dodge keys and other chrylser brands an assume they are interchangeable? I've forgotten the other part number the sympathetic dealer gave me. Ended in AA. I still have the one key because the dealer want the better part of NZ$500 for a new one.
