GM Passlock Security Light Issues - RepairPal

tighten the cables some more--if no go then call dealer and ask to speak to a service tech for reset

Normally this indicates an upcoming problem, or a very shotty bypass method. The only trouble is when you try to sell the car, Here is a link that may help you.

Hello: Put the following in your search engine "How to remove GM VATS Passkey Passlock system from GM cars. Your car has the Passlock system.

leave the key forward so dash lights are on for 10 min and then it should reset the security system and start up

Im guessing you tried to bypass the key in the ignition/steering column. This is ok unless the actual problem was in the TDM (theft deterrent module) In this case, the 2 wire bypass does nothing. There is another way to bypass this. Check out this link for tons of info and some DO IT YOURSELF options. Ive done several key bypasses and tons of full bypasses. They both work well, it just depends on what part is failing. I think you need the full bypass to eliminate that TDM.

you should have a remote or try locking and unlocking the drivers door with the key. if this doesnt work then try the pass/side door lock, lock and unlock that door.hope this helps.

Try turning the key to the on postion-not crank, just to he postion right before cranking. leave it in that postion for 15 min, Do this three and after the third time go ahead an try to start it. Hopefully this will reset your security for you.

Yes, the key,ignition, or Theft Deterrent Module is not funtioning properly. You can start changing these out 1 by 1, or bypass the whole system for about the cost of a new key. This link explains and will help you.
