Mercedes immobiliser systems — what you need to know
Technical notes on Mercedes key programming
- FBS3 (2003-2016): uses an EIS module (Electronic Ignition Switch). Each new key needs the EIS password — readable via dedicated tools at your location.
- FBS4 (2017+): brand new architecture using EZS module and stronger encryption. Requires bench-style programming with certified equipment.
- Infrared communication: Mercedes IR keys communicate via the infrared LED on the front of the key — keep the front clean for reliable operation.
- Keyless-Go: proximity-based unlocking. Each new key is paired with the antennas and the EZS.
- Stolen key protection: DKP can deactivate stolen keys on most Mercedes models, securing the vehicle against repeat theft attempts.

Mercedes key replacement — FAQ
How long does a Mercedes key replacement take?
A Mercedes-Benz key replacement typically takes 90 to 180 minutes. FBS3 vehicles can be programmed via OBD while FBS4 (post-2017) requires EIS/EZS reading and bench programming, which can extend the job to 3 hours.
How do I get the price and how do I pay?
The quote is free by phone or WhatsApp. Your final price is confirmed as soon as you send your vehicle registration document (or, at minimum, the licence plate number and the full intervention address). You then pay online or directly on site, after the intervention, by card or bank transfer, with no hidden fees.
Can DKP make a Mercedes key without the original?
Yes. Total key loss on a Mercedes-Benz is one of our specialities. We read the EIS (Electronic Ignition Switch) to extract the password and programme a brand-new key, all on-site at your address.
What is the FBS4 immobiliser?
FBS4 is the fourth generation of Mercedes-Benz Flexible Authorisation System, used on most models from 2017 onwards (W213 E-Class, W222 S-Class, W205 C-Class facelift). It uses stronger encryption and requires specialist tooling — DKP technicians carry the certified equipment.
Does DKP work on Mercedes EQ electric models?
Yes. The full Mercedes-EQ range (EQA, EQB, EQC, EQE, EQS, EQV) is supported. The key system is identical to the equivalent combustion model, using FBS4 architecture.
