Battery safety

  • Keep coin batteries away from children. A swallowed coin cell can cause severe internal burns within hours. If you think a battery has been swallowed or placed in the body, get medical help immediately.
  • If the battery compartment does not close securely, stop using the key and keep it away from children.
  • Hold the new battery by its edges and avoid touching the circuit board or contacts.
  • Replace only with the same type, and recycle the old battery according to local rules.

If the key still doesn't work

  • Check the battery orientation and that the cover is fully closed.
  • Make sure the new battery is the exact code listed above — similar sizes are not interchangeable.
  • If the buttons still do not work, contact a franchised dealer. We do not cover key programming or security systems.
