Chevrolet Suburban 2007-2014 Key Programming Procedure
The following are the key programming procedures for the 2007 and 2014 Chevrolet Suburban.
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 Chevrolet Suburban
The Chevrolet Suburban is a big SUV manufactured by Chevrolet. With a history stretching back to 1935, it is one of the most enduring vehicle nameplates in the United States.
Many American automakers, notably Dodge, Plymouth, Studebaker, Chevrolet, and GMC, used the term “Suburban” to describe a windowed, station wagon-style body on a commercial frame. Only General Motors continued to manufacture a vehicle branded as a “Suburban” after the production of the Dodge Town Wagon ended in 1966, and they were granted an exclusive trademark on the word in 1988. The Suburban is one of the most spacious SUVs on the market, with three rows of seats and a vast cargo area behind them.
The Suburban is available in three trim levels: LS, LT, and LTZ. All trims come standard with a 5.3L 310hp V8, however the LT and LTZ, which are also available in flex-fuel versions, can upgrade to a 6.0L 366hp V8. All are equipped with a 4-speed automatic transmission and come in either rear-wheel drive or full-time automatic four-wheel drive configurations.
GM issued a GM-wide recall (no.08V441000) on August 29, 2008, affecting 857,735 vehicles built between 2006 and 2008 and fitted with heated windshield washer fluid option, including the 2007-2008 Chevrolet Suburban. The system was prone to shorting out, resulting in a loss of function, smoke, a potential fire, and the failure of other electronic systems in the vehicle. GM advises owners of impacted vehicles to see their local dealer to get the problem fixed.
The NHTSA’s safety tests for the 2007 Suburban yielded mixed results. The Suburban received a 3-Star rating in both two-wheel drive and four-wheel drive rollover tests. In front-impact crash tests, it performed better, obtaining 5-Star ratings for both driver and passenger side impacts. The Suburban was not subjected to any side-impact testing.
Chevrolet unveiled the twelfth generation Suburban at Little Caesars Arena in Detroit, Michigan on December 10, 2019. This time, GM chose to launch the Chevrolet full-size SUVs first. Originally scheduled to begin production in April 2020, GM began production on the Suburban on May 18, 2020, and it will be available in dealerships in June 2020.
Based on the same GMT T1XX platform as the Silverado 1500, the Suburban distinguishes itself by swapping the Silverado’s live axle and leaf springs for an independent rear multilink suspension setup with coil springs, lowering the vehicle’s floor and creating more room in the cargo area as well as the second- and third-row seats. The Suburban grew in length to 225.7 inches and in wheelbase to 134.1 inches, despite being 15 inches shorter due to the rear wheelbase moving back by 5 inches, making it the largest and longest SUV in the extended length segment. It gains 2.2 inches of third-row legroom and 2.0 cubic feet of cargo space behind the third row. The towing capacity of the twelfth generation models was increased.
