Chevrolet Express 2008-2014 Key Programming Procedure
The following are the key programming procedures for the 2008 and 2014 Chevrolet Express.
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 Express
The Express was given a mid-cycle makeover in 2003. The bodywork ahead of the windshield was changed in addition to significant frame and chassis modifications. The revised front fascia (created as an improved crumple zone) brought the model line closer in line with the GMT800 full-size pickup trucks debuted in 1999; the model line also established a degree of parts commonality between the two model lines. The dashboard was redesigned, and multiplex wiring was added to the interior, in addition to dual-stage airbags (adding increased functionality to the interior electrical system).
The Express was the first vehicle (since the Corvair cargo van) to be sold with optional 60/40 panel doors on both sides of the vehicle; however, the option was only available with the standard-length body (requiring doors on both sides). The configuration was phased out after the 2008 model year.
The Express has experienced modest modifications to the model line since its 2003 model revision. Side-curtain airbags and standard stability control (first introduced for 3500-series vans in 2005) were added to the Express passenger van for 2008. The steering wheel was also modified. The dashboard was upgraded in 2011. (including Bluetooth compatibility and a USB port). Optional navigation, a rearview camera, and a parking assist system were added to higher-end passenger vans for 2013. All radios were digitally adjusted in 2015, and a 120-volt outlet was added to the dashboard. For 2018, all models of the Express were equipped with sealed-beam headlights, instead opting for the four composite headlamps found on higher-end passenger vans. Lane departure warning systems and collision alert warning features were added to higher-end passenger vans for 2019.
The Chevrolet Express is entering its 25th year of production for the 2021 model year, matching the third-generation G-series Chevrolet Van in model life.
The optional CD player was dropped for 2022.
The Chevrolet Express is built on the GM GMT600 chassis, which was designed specifically for full-size vans. The model line employs a full-length ladder frame with boxed forward frame rails, based loosely on the GMT400 chassis of the fourth-generation C/K trucks. The GMT600 was available in two lengths: a normal 135-inch wheelbase and a longer 155-inch wheelbase (created by moving the front axle 10 inches forward on both versions). The 110-inch short-wheelbase chassis was not replaced because it overlapped with the Chevrolet Astro/GMC Safari mid-size van.
The GMT600 chassis was renamed GMT610 in 2003, following a significant makeover. The GMT610 had a three-section fully-boxed frame, similar to the GMT800 chassis. The GMT610 used the front suspension of the GMT800 pickup trucks, with short-long arm front suspension (rear-wheel drive) and torsion-bar front springs, with minor modifications (all-wheel drive). Another change was the introduction of four-wheel disc brakes, which standardized anti-lock brakes (ABS). The GMT610 platform was also available with full-time all-wheel drive, which was a first in the full-size van category.
