Pontiac Grand Prix 2005-2012 Key Programming Procedure



The following are the key programming procedures for the 2005 and 2012 Pontiac Grand Prix.


ADD DUPLICATE KEY (Requires at least one working key):

1. Verify that the new key has “PK3” or “+” stamped on it.

2. Insert the original, already programmed key into the ignition lock cylinder and start the engine. If the engine will not start, see your dealer for service.

3. After the engine has started, turn the key to LOCK/OFF and remove the key.

4. Insert the key to be programmed and turn it to ON/RUN within 10 seconds of removing the previous key. The security light will turn off once the key has been programmed. It may not be apparent that the security light went on due to how quickly the key is programmed. (If your vehicle does not have a security light (04-07 Grand Prix, Bonneville, Impala), wait 10 minutes 45 seconds to make sure the key has been programmed).

5. Repeat steps 1 through 4 if additional keys are to be programmed.



About Pontiac Grand Prix

The Pontiac Grand Prix is an automobile manufactured by General Motors Corporation’s Pontiac division. The Grand Prix name was first applied to cars in the personal luxury car market segment and the mid-size offering, slotting below the large Bonneville in the company’s lineup, and was first introduced as part of Pontiac’s full-size model offering for the 1962 model year. The Grand Prix is Pontiac’s largest automotive offering in production as of mid-model year 2006, having surpassed the recently cancelled Pontiac Bonneville program.

The Grand Prix was updated for 2004 on a revised version of the GM W platform. On May 5, 2003, the first 2004 Grand Prix was built. The GXP’s small-block 5.3 L V8, the Grand Prix’s first V8 since 1987, is a notable addition to the 2005 line. The GXP has Bilstine monotube shocks, a staggered tire fitment of 255 front and 225 rear, 18″ aluminum forged Alcoa wheels until mid 2007, when they were replaced by Korean manufactured similar looking wheels, upgraded sway bars, and upgraded cross drilled and directionally veined rotors. During production, GM engineers noticed a significant difference in torque steer when using different tires. They approached Brigestone and asked for a custom tire to further eliminate torque steer. The resulting tire is a Potenza RE050A variant, with TPC Spec 1269 front and 1270 rear. The tires in this specification are classified as all-season tires and are suitable for use in snow and ice. In addition to the V8, the V6 Supercharged GTP models now have a Generation 5 Eaton M90 Supercharger and stronger internals. As a result, the engine now produces 260 HP and 280 LBFT of torque. With the closure of the Oshawa plant that manufactures the car in 2008, production of the Grand Prix is likely to end, and it will be replaced by the Zeta-based G8 in 2009.

The W-bodies underwent a major redesign in 1997. On August 12, 1996, the first 1997 Grand Prix was constructed. The second generation W-body Grand Prix sold well after being widely promoted for its “wide track” appearance. In 1997, there were three trim levels to choose from: SE, GT, and GTP. Beginning in 1997, a supercharger was added to the GTP, increasing power to 240 hp. This generation saw the introduction of a heads-up display as well as a performance shift that increased shift pressures for faster engagement. The Grand Prix was manufactured at the Fairfax plant in Kansas City, Kansas, until 2003, when production was moved to Oshawa, Ontario, Canada. The Fairfax plant was then retooled to produce the current Chevrolet Malibu. The last Grand Prix coupe rolled off the assembly line on July 19, 2002, and the coupe was replaced by the Pontiac GTO for 2004.

With intake and exhaust improvements, the 3.4L DOHC V6 gains 5HP. All Grand Prix coupes receive a sport package that includes five-spoke alloy wheels and dual exhaust. This is the final year for the first-generation W-body Grand Prix.
