Buick Terraza 2006-2011 Key Programming Procedure


The following are the key programming procedures for the 2006 and 2011 Buick Terraza.


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 Buick Terraza

When Buick decided to offer its first minivan, the Terraza, a badge-engineered General Motors minivan, was dubbed a “luxury crossover sport van” in an attempt to minimize the associated stigma. In other words, the Terraza was a minivan with a higher stance, a longer nose, and optional all-wheel drive. While it shared a platform with several corporate siblings, including the Chevrolet Uplander, the Buick Terraza offered a few distinguishing features and styling tricks that gave it a more upscale feel. The uplevel versions’ nicely finished leather and wood trim provided an elegant ambience not seen in the Buick’s more lowbrow relatives, and it also came with more standard features.

However, in terms of driving refinement and safety features, the Buick Terraza lagged behind segment leaders (as well as newer true crossovers). Before settling on this “luxury crossover sport van,” buyers should consider the Honda Odyssey, Toyota Sienna, or even Buick’s own Enclave.

Buick launched the Terraza in 2005 and phased it out after the 2007 model year. Initially, it was equipped with an underwhelming 3.5-liter V6 engine producing 200 horsepower and mated to a four-speed automatic transmission. All-wheel drive was available as an option. Buick Terraza minivans were available in three trim levels: CX, CX Plus, and CXL. The well-equipped CX included all of the expected popular features, while the CX Plus added a sport-tuned suspension, dual-zone climate control, and an auto-leveling rear suspension. The top-tier CXL model included alloy wheels, rear air conditioning, rear parking assist, and eight-way power front seats.

The Buick Terraza comfortably seated up to seven people and provided plenty of storage space, with the second and third rows folding down to provide up to 137 cubic feet of space. The Terraza’s third row, unlike most other minivans, did not fold completely into the floor, but it could be removed. The rest of the cabin was opulent, with convincing faux wood and double-stitched leather seats with contrasting piping. Passengers could adjust the DVD player and storage compartment components using a modular roof rail system, and folding center trays were located between the first and second rows of seats. There was also a remote vehicle start system available, which allowed you to heat or cool the cabin before getting in.

Used-car buyers should look for 2006-and-later models, as these vans gained first- and second-row side airbags and the more powerful 3.9-liter V6 engine under the hood of front-wheel-drive models. Rear DVD entertainment was made standard, with the PhatNoise digital media system available for those who wanted more options. For 2007, all-wheel drive and the 3.5-liter V6 were dropped.

Despite its hefty weight, we found the Buick Terraza’s large V6 capable of delivering respectable acceleration around town and ample power for merging and passing at highway speeds. The suspension provided an acceptable balance of ride comfort and responsive handling, but other minivans provided sharper reflexes and a tighter turning radius. Braking distances on the Terraza were also a little on the long side. Moreover, despite Buick’s advertised “QuietTuning” technology, cabin noise levels were higher than average and not as quiet as we had hoped.
