Mercedes Benz Key Replacement

Mercedes Benz Key Replacement in San Jose

Mercedes Benz vehicles have used a range of key systems over the years. Older models often relied on a basic transponder key or a remote-head key where the transponder chip and remote buttons are combined in one head. Many later Mercedes Benz models use a proximity smart key (often called a SmartKey) with keyless entry and push-to-start, letting you unlock and start the car while the fob stays in your pocket. Because these systems differ by year and model, the exact key your car needs is something we confirm with you by phone before any work.

Every modern Mercedes Benz pairs its key to an electronic immobilizer and anti-theft system. The car checks for the correct encrypted key signal before it will start, which is why a replacement key has to be cut and electronically programmed to your specific vehicle, not just copied. You will see plenty of Mercedes Benz models on South Bay roads, including the C-Class, E-Class, S-Class, GLC, and GLE.
