Retrieving the mechanical key

Polestar models use a new key fob style first introduced by Volvo in 2021.

Polestar 1 and 2

It should be noted that in 2021, a smart phone app is also available Polestar models and can be used to open and start these vehicles. A key card is added beginning in 2024.

Beginning with the first Polestar models, a new style key fob is used (right). To retrieve the mechanical key or key blade, look for a slide lever on the top of the key ring end of the fob. This will free the front cover, which needs to be removed.

To do this, push the cover slightly down and away from the key ring end. It can then be pulled up and out, exposing the mechanical key. The key blade can then be lifted out.

The key holes on most models may not be immediately visible, but help with that can be found below.

Polestar 3 and 4

The new (2025) Polestar 3 and Polestar 4 models do not use a mechanical key. The Polestar 3 features a rechargeable key fob (far right) while the Polestar 4 uses a fob with a replaceable battery. They both add an accessory key card (right). The instructions for their use when their charge is low are below.

Getting Inside

Note: Unlocking the vehicle with the mechanical key will set off the alarm. Following the start procedure will also turn off the alarm.

Polestar 1

The Polestar 1 features a door handle that is flush to the car’s body. Push the front of the handle inward and pull away the back, as seen to the right. The key hole is now exposed. As above, insert the mechanical key and turn it clockwise to unlock. Remove the key blade and release the handle. Pull the handle once again and you are in the car.

Polestar 2

In the Polestar 2, the key hole is also hidden, but easily found and nothing needs to be removed. Simply pull the door handle out as far as possible and the key hole is exposed, as shown in the image.

Insert the mechanical key (it may be awkward to get at) and turn it clockwise to unlock. Remove the key blade and release the handle. Pull the handle once again and you are in the car.

Polestar 3 and 4

A mechanical key is not available to unlock the Polestar 3 or Polestar 4. The smart phone app, the vehicle’s key card or depleted key fob will be needed. With the Polestar 3, the card or fob is touched to the front of the driver’s door handle (far right). With the Polestar 4, the card or fob is touched to the middle of the door pillar just behind the driver’s door (right).

The key card or key fob must be laid flat on the surface and the key fob logo should be facing out.

Polestar models examined include the Polestar 1, Polestar 2, Polestar 3 and Polestar 4. Model years 2021, 2022, 2023, 2024, 2025 and 2026.
