Newer versions of the Pontiac G6 use a passive ignition immobilizer system called PASS-Key III. The system uses radio frequencies to communicate with the key fob you use to start the G6. When you place the key into the ignition, the key and car communicate to ensure the key is legit. If the theft system does not get the correct frequency back from the key, it will not allow you to start the car. Use the correct G6 key to restart your vehicle.

Step 1

Open the G6 door and insert your key into the ignition.

Step 2

Turn the ignition key to crank the engine. If the car will not restart, use a secondary car key to crank the engine. If neither work, then continue to step 3.

Step 3

Listen to the engine as you try to crank it. If you hear a sputtering sound or see the inside lights dim as you turn the key, you have an issue with the battery that is preventing the engine from restarting. This can be a dead battery or just a problem with the starter. In either case, you will need to take the car in to get serviced.

Step 4

Locate the engine compartment fuse box under the front hood near the engine block on the driver's side. The box has an electricity symbol on the front.

Step 5

Pull off the cover and then remove the fuse box to take a look at the fuses.

Step 6

Check fuse number 32. This is the Run/Crank relay. It is the large fuse located in the center towards the bottom of the console. If the silver color band in the fuse is burnt or broken, you have a blown fuse that needs to be replaced before the car will restart.

Step 7

Take the car in to the dealership if none of the above steps work, as you most likely have an error with your ignition key or the Pass-Key III system itself. You cannot reprogram a key yourself without one that already is correctly programmed, so you must use the Pontiac dealership or a alternative locksmith to program the key.
