Keep getting a starting system disabled on 2006 Lacross

Donna brown you got a whole lot going on here. I would suggest that you take it and have the OBD scanned. Generally it is the theft deterrent system that generates the message. Sometimes after the battery has been changed or the battery has been jumped a relearn procedure needs to be performed. It is also possible that this is a failing crank sensor. You should be able to find the cause or issue by scanning the control module for the history codes.

Security Relearn

1. With a master PASS-Key III key, turn ON the ignition, with the engine OFF.
2. Observe the STARTING DISABLED DUE TO THEFT message on the driver information center (DIC), after approximately 10 minutes the STARTING DISABLED DUE TO THEFT message on the DIC will turn off.
3. Turn OFF the ignition, and wait 5 seconds .
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes .
5. With a master PASS-Key III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password. IMPORTANT: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. from here
