Replacement Keys

At MercedesKeys.ie we can supply you with a replacement car key whether you have lost it or require a spare. Our highly skilled Automotive locksmiths will come to your home, place of work or breakdown location to supply you with a replacement Mercedes-Benz car key. This process firstly requires our specialist to open the vehicle, this is done by picking the door lock/boot lock and is none descructive meaning there will be zero damage to the vehicle. Once the lock is picked open, our specialist will be able to read the internal parts of the lock which will allow us to then produce the mechanical key part that sits inside of your key.


Once inside the vehicle we will remove the EIS module and read the security data from its microprocessor. Once we have read this data we will then be able to produce your replacement car key. The key will be produced with a special programmer allowing us to replicate a key you would have received from the manufacturer.

In the final step we would fit the EIS module back to your car and fully test the newly programmed key fob.
