GMC Yukon XL 2007-2014 Key Programming Procedure
The following are the key programming procedures for the 2007 and 2014 GMC Yukon XL.
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 GMC Yukon XL
On January 14, 2020, GMC unveiled its twelfth generation Yukon XL in Vail, Colorado, alongside its full-size sibling Yukon. The Yukon XL, like the Suburban, had an independent rear suspension, a 3.0-liter inline-six turbodiesel engine, and a top-shelf suspension option with air springs and magnetic-ride shocks, a standard 5.3-liter V-8, an optional 420-hp 6.2-liter V-8, and a 10-speed automatic transmission that was standard across the lineup. It also gained 4.1 inches in wheelbase but only 0.9 inches in overall length, leaving it short of the Suburban. The dashboard comes in two styles: one similar to the Suburban and another with a larger entertainment screen that is exclusive to the Denali. The Yukon XL’s design is based on GMC’s design language, with the front grille resembling the Sierra but the tailgate resembling the GMC crossover SUV lineup, with the lights extending to the tailgate doors.
The lineup of level trims has also expanded, with the SLE, SLT, and Denali now joined by the 4WD-exclusive AT4, the latter of which comes standard with the Magnetic Ride Control electronically adaptive dampers, AT4-exclusive leather-appointed seats and stitching with a unique Jet Black interior color and Brandy accents, a heated steering wheel, heated and ventilated front seats, heated second row seats, and heated third row seats. For this generation, the Denali level offers three packages, with Deluxe joining the Premium and Ultimate options, and becoming the only trim to offer quad exhaust tailpipes.
The Yukon XL went on sale for the first time in Mexico (GMC had only offered the Yukon in that country due to GM not wanting the Yukon XL to be cannibalized in terms of sales with the Suburban, which is also that country’s best selling SUV), where it is only available in the Denali trim.
Beginning with the 2018 model year, Chevrolet offered a “Signature Edition” package/trims for the Suburban. Each of the specialty versions was available in the LT and Premier trim levels. Beginning with the twelfth generation Suburban for the 2021 model year, the Z71 and RST became the fourth and fifth level trims, respectively, while the rest remained as package features.
Chevrolet debuted the updated Z71 Suburban at the Texas State Fair on September 26, 2014, alongside the debut of the Texas Edition Suburban, the latter due to Texas having the most units of Suburbans sold in the United States (as of August 2014, sales of Chevrolet SUVs in Texas were up 37 percent) and to commemorate the 60th anniversary of GM’s Arlington Assembly plant; production of the Z7 began on September 26, 2014.
This version, like previous Z71 Suburbans, was only available in 4WD LT trim, with a front skid plate, off-road tires mounted on 18-inch wheels, a unique grille, running boards, and “Z71” identification inside and out. There are also fog lamps, front tow hooks, and front parking assist. The 2016 Z71 package was modified once more, with portions of the Z71 items added to the Texas Edition package as an optional feature by customer request being discontinued, making it a stand-alone package. Beginning with the twelfth generation models, the Z71 package was upgraded to a level trim.
The Texas Edition Suburban, which joined the Tahoe and Silverado in the Texas Edition lineup for the 2015 model year, was available in both LT and LTZ trims, with a maximum trailering package, twenty-inch polished aluminum wheels (on LT models), twenty-two-inch premium painted aluminum wheels (on LTZ models), and an exclusive “Texas Edition” badge. Chevrolet discontinued the LTZ package for the 2016 model year, but modified the LT package to remove the requested Z71 features. The Texas Edition will remain available for the LT and Premier trims only when combined with the Luxury, LT Signature, or Premium packages in the twelfth generation Suburban.
