If you only have one key to your vehicle, it is highly recommended that you get yourself a spare. It is far cheaper, more convenient and less stressful than finding yourself in a position where you have lost your only key or locked it within your vehicle.
Your spare key can be just the key with a programmed transponder or a remote key which will also allow you to lock and unlock your vehicle using your remote.
To create a spare key we need you to have a working key present, this will allow us to create the additional keys more efficiently and therefore at a lower cost to you.
