Upgraded Key
Has anyone got one or seen one?
Or better yet does anyone know where to get one?
Allows you to remotely:
Lock and unlock Car
Turn Heating on / off
Start and stop the engine
Operate demister
Premium Smart Key
Has the same features as the upgraded smart key but with an LCD screen which also displays status information about the car such as locking, interior temperature and whether the engine is running. Note that these Smart keys are an unusual option to find and are rarely noted on auction sheets.
