GM vehicles use three different style keys, of which Buick uses the last two. There are several starting options, and we have videos here.

So, find your model, and if the main start battery is still good, we’ll get you underway…

With the flip key key fob, the mechanical key remains attached to the fob, but several back-up locations are used. In the Buick Verano, Regal (through 2017) and pre-2014 Lacrosse, remove the cup holder from the center console in front of the storage area. This may be the entire cup holder assembly (above right), or simply a cup holder insert (below right).

Look for a notch at the top rear of the cup holders to insert a finger or tool to aide removal. Then place the transmitter in the transmitter pocket with the buttons facing up. The pocket will be shaped somewhat like the key fob.

Note that, as can be seen, the console areas look different from model to model, but the pocket is indeed beneath the cup holders. With the key fob in place and with the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.

The back up location is changed in the Regal beginning with the 2018 model year, and the car uses a newer key fob. The spot is in a narrow compartment at the front of the center console, as can be seen in the image at right. And for the first time in any GM vehicle, the spot is marked. There is an image of a padlock with lines radiating from it, meant to invoke radio waves.

Place the key fob in the compartment and step on the brake and start the vehicle as normal using the Start / Stop button.

For the LaCrosse in 2014, the transmitter pocket is moved into the storage area inside the armrest near the auxiliary power, USB and audio ports (right). Place the transmitter in the pocket.

Once again, with the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. Look for video help here.

The newest key style was introduced in 2014. It features a removable key. Note that there are still some flip keys in use. The Buick Encore, with  exception, and Envision, until 2021, crossovers will use this spot. Simply drop the key fob into the front cup holder with the buttons up, and start the car as normal. Check out videos for these models here.

The exception is the Encore GX, beginning with the 2020 model. There is a small depression at the rear of a tray on the center console that is just in front of the center console storage area. This is the back up spot. The new Envista model introduced in 2024 uses this spot as well. Drop the key fob onto this spot with the buttons up and start the car as normal, again pressing the Start / Stop button while stepping on the brake.

And the 2021 Envision finds the back up spot moved to the front of the center console storage area, See the image to the right. Inside and at the front of the console there is a small, flat depression. Drop the key fob onto this spot with the buttons facing up and start the vehicle as normal, stepping on the brake while pushing the Start / Stop button. See a helpful video here.

Finally, the Buick Enclave gets keyless start for the first time in 2018. The back up spot is beneath the rubber mat at the bottom of the center console. Remove the mat and place the transmitter on the fob-shaped depression that is now  visible. As always, with the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. We’ll post more information as it comes available.

Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.
