Have You Lost Your Vehicle Key Or Had It Smashed In The Lock?

The standard key is obsoleted by this new method. A transponder key’s built-in chip verifies the key’s authenticity to the car’s ECU and gives the ECU the green light to start the engine.

However, you might expect to pay more than if you had gotten a regular Mercedes key.
