HelloCustomerWelcome to justanswer!

 

Is it not starting now?

Customer: replied 7 years ago.
We have been putting nail polish on the key and it eventually starts, then it may start for a few times and we stip the key of the old polish and apply a new coat and then it starts.
Expert:  Anthony replied 7 years ago.
Ok, but is it doing the no start now?
Customer: replied 7 years ago.
It would not start this morning until we repainted the key, then it started.
Expert:  Anthony replied 7 years ago.

Ok, next time it wont start, don't paint the key but do the procedure below and it will stay working. You actually should remove the nail polish from the key and do the procedure.

 

30 Minute Learn Procedure

  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON (vehicle will not start).
  3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
  4. Turn OFF the ignition, and wait 5 seconds.
  5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the password XXXXX the next ignition switch transition from OFF to CRANK.

    Important

    The vehicle learns the password XXXXX the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

     

  6. Start the engine. The vehicle has now learned the password.

We tried what you suggested and it did not work, however we eventually got it to start. The Security light now stays on all the time. Is there any way we can bypass or turn off the Security system ???
Expert:  Anthony replied 7 years ago.
If the light is staying on, that means something is wrong inside the Body Control Module. Theres no way to bypass the security system at this time. You really need to get the vehicle over to a gm dealer to have the whole system tested. At first it seemed like the system forgot your key program but now I can see its more than that. Most likely it will either need a new pass-lock sensor or Body Control Module.
