Replacing the battery in the key

The battery in the key needs to be replaced when it has become discharged.

 Note

All batteries have a limited service life and must eventually be replaced. The service life of the battery varies depending on how often the vehicle/key is used.

 Warning

Check that the battery is positioned correctly, with the correct polarity. If the key is not to be used for any length of time, remove the battery to prevent it leaking and causing damage. Batteries that are leaking or damaged may cause chemical burns on contact with the skin, so wear protective gloves when handling damaged batteries.

  • Keep batteries out of the reach of children.
  • Do not leave batteries lying around in places where they could be swallowed by children or pets.
  • Batteries must not be dismantled, short-circuited or thrown into naked flames.
  • Do not charge non-rechargeable batteries as this may cause an explosion.

Check that there is no damage to the key before use. If damage is detected – being unable to close the battery cover properly, for example – the product should not be used. Keep defective products out of the reach of children.

 Important

Make sure that exhausted batteries are disposed of in a manner which is kind to the environment.
