Re: security system
Power lock the doors, try the key thing including @ the lift gate. Once the ZJ is running/starts, there is a purple wire w/yellow tracer you can ground out, or get to the security relay next to the glove box (must remove glove box/dash pad) and pull the relay WHILE THE VEHICLE IS RUNNING. Stress having the Jeep running so the computer doesn't think the security system is disabled. HTH.
