The dealers scan tool is required.
I had same problem with my 2002 liberty. It was the park sensor. I had to turn on the key and put it in neutral then back to park to get the key out (might have to do it a couple of times). Once I did that I could get the key out. Then I had to remove the center console cover and found that the park sensor was loose. I tightened it up and haven't had a problem since. Hope this helps!
Yes.
if u have a copy of the key yes if u dont you will need to go to jeep and ask for a new key (form my knowledge)
The dealer has to use his scan tool to do it.
There is a malfunction in the "chip" key system.
Mine was in the glove compartment.
Most of them, yes. If the key is grey, or is the big key with built in remote then definatly yes.
It could have the Sentry Key system (chip key).
The key code is accessed by the dealer from their computer system.
If the head of the key is GRAY or TAN, than yes it does.
Unfortuately if you don't have a least 2 keys for you can, your going to have to go to dealership for a new one, its gonna cost $300..
