In a 1993 jeep grand Cherokee Laredo will the security light flashing on the instrument panel keep the vehicle from starting and how to fix?

Answer 1

using your key, must reset security, lock driver door and than unlock with key, Had problem and started

Also:

If that doesn't work, using your key lock and unlock you rear lift gate 2 times and that should reset it

Additional Info:

I currently have this problem - you can also lock and unlock the passenger door with your key.
