Key replacement
Mercedes keys: EIS, FBS3 and FBS4.
Most Mercedes models use an infrared key that talks to the Electronic Ignition Switch (EIS, or EZS), and the security generation matters: earlier cars use FBS3, while later cars use FBS4, which is harder to work with when every key is lost. Keyless-Go cars add proximity entry, and Sprinter and Vito vans have keys of their own.
Key systems we work with
FBS3 & FBS4 Security Protocols, Electronic Ignition Switch (EIS/EZS), Electronic Steering Lock (ESL), Keyless-Go Infrared Keys
Faults we see on Mercedes-Benz keys
ESL steering lock failure (key won't turn in EIS ignition), dead infrared fob LEDs, and keyless entry sync loss.
Lockouts
Locked out of a Mercedes-Benz?
Deadlocked C, E and S-Class saloons with the keys in the boot are opened with Lishi HU64 and HU106 picks, and Keyless-Go lockouts are handled through the emergency blade lock.
Tools
Lishi HU64 & HU106 Mercedes Laser Lock Pick Tools
Typical lockouts
Keys locked in boot of deadlocked C/E/S-Class, Keyless-Go lockout override, and emergency blade manual door pick.
Programming
Mercedes-Benz key programming.
We code keys to EIS/EZS ignitions on FBS3 and FBS4 cars and diagnose the electronic steering lock (ESL) faults that stop older Mercedes keys turning.
Modules and systems

Questions
Mercedes-Benz key questions.
My Mercedes key won’t turn in the ignition and the dash is dead.
On some older C and E-Class cars this is the electronic steering lock failing rather than the key. We can diagnose it at the car and explain the options.
What’s the difference between FBS3 and FBS4?
They’re two generations of Mercedes key security. Adding keys to FBS3 cars is generally straightforward; FBS4 cars need more involved work, especially when no working key is left, so tell us the year of the car when you call.
Do you do Sprinter and Vito keys?
Yes, including spare keys for vans in a fleet.
