To ensure the best from it, remember these tips:

*Don’t allow the key to get wet, and keep away from high temperatures
*Battery performance is less in cold weather
*Range of the remote is less when the batteries are low

If you lose a key, please contact our service department so that the key can be de-authorised from your car. this will help to maintain the security.

For cars equipped with memory seats, each key can store 3 seat memories. If you alternate keys, you will need to set the seat memory for each key.
