About Mercedes Car Keys

Since the mid 1990's vehicle manufacturers have been required to install a passive immobiliser system. Mercedes-Benz decided to accomplish this, initially, by using an infrared central lockcking system. Mercedes-Benz later then released a new type of immobiliser, this immobiliser still incorporated an infrared system but this was not for the central locking system. The infrared system became a passive immobiliser system that only operated when you inserted the pod style key into the ignition. The central locking was converted over to a more modern RF based system.


The design of Mercedes-Benz car keys makes them naturally prone to physical damage and water damage. If this happens then the dealer would have to supply a full new key ordered from Germany which can take up to 10 working days to arrive. Here at MercedesKeys.ie we can come to you and supply a replacement key on the spot or you can post your damaged key to us and we will repair it and send it back with a 48hr turn around.
