We come to the vehicle
Mercedes does not use a conventional transponder. The key communicates with the vehicle over infrared, and the security data lives in an electronic ignition switch and control module pairing that is deliberately difficult to access.
Later-generation Mercedes vehicles encrypt that data to a standard that locks out ordinary diagnostic equipment entirely. This is genuinely specialist work, and the vast majority of locksmiths — in Louisville and elsewhere — cannot do it.
Key Squad can. Mercedes work is a core part of our practice rather than an occasional favour.
What matters on a Mercedes-Benz
Infrared architecture
Mercedes keys talk to the car by infrared rather than radio. A key that looks physically fine can have a failed emitter, which is diagnosable and sometimes repairable.
Sprinter and Metris vans
Commercial Mercedes vans are common in Louisville fleets and use the same key architecture. We prioritize fleet downtime.
Later-generation encryption
Newer security generations require specialist access. We maintain it, which is why other locksmiths send these calls to us.

Mercedes-Benz key questions
Can a locksmith really make a Mercedes key?
A properly equipped one can. Most cannot, because Mercedes security requires equipment and access well beyond a standard key-programming tool. We do this work regularly, including all-keys-lost.
How much does a Mercedes key cost in Louisville?
Generally $420 to $950 depending on the model year and security generation. That is typically well below dealer pricing, and it does not include a tow because we come to you.
My Mercedes key works intermittently. Is it dying?
Possibly. Mercedes keys can suffer a weak infrared emitter or a worn internal battery contact. Both produce intermittent behavior that gets steadily worse. We can test the key directly rather than guessing.
