I have a 2000 Jeep grand Cherokee. It was dying out on me for no reason at random times I went to run a diagnostic on it only to get told the computer in the jeep was for a 2001 and mine is a 2000 so therefore they could not diagnose it. So I bought a new computer for it programmed to my vehicle, put it in and now the security system is messing up the lock is staying on and the vehicle dies right out and wont stay on? Please help

When you replace computers you need to have a pro input the security details otherwise you will have your problem you do now. No matter what the a-holes at the autoparts tell you

When a computer is replaced in the newer models a mechanic has to program in the security system otherwise you get what you have now. You cannot reset it because it doesn't recognize it.

Is there a way to completely disable the security at home, like wiring? A way to remove the key lock security that is preventing start up?

The alarm system is built into the computer of the car and cannot be bypassed.

The system is not reading the key. I was just wondering if there would be any way to disarm it, atleast to get the car to a garage for proper fixing?

I would inquire first at the dealer's parts department to see if they can make you another key. The original selling dealer keeps the key codes on file for at least seven years. After that, and any other dealer can access the information from Chrysler's web site. They only need the vehicle ID number, and possibly proof of ownership if you have never had the vehicle worked on there before.
