FBS4 (Fahrzeug-Besitz-Schutz 4) is Mercedes' fourth-generation immobiliser security system introduced on 2016+ models. It uses advanced encryption to prevent unauthorised module swapping and key cloning. All control modules (ECU, TCU, DSM, etc.) are "personalised" to the vehicle and cannot be replaced without proper FBS4 programming.

We offer the same technical capability as the main dealer, but with faster service, mobile repair options and lower total cost. Main dealers only fit brand new units — we can virginise and program used or reconditioned modules where applicable, saving you hundreds of pounds.
What's the difference between FBS3 and FBS4?
FBS4 (2016+) uses stronger encryption and more secure authentication than FBS3. It requires specialist equipment and software to virginise and personalise modules. Most aftermarket tools cannot handle FBS4.
Can you virginise a used module I've purchased?
Yes, we can virginise and personalise used FBS4 modules where applicable. For some module types, we need the original module's FBS4 data file. For others, we can perform extended personalisation without the original data.
Do you need to open the module?
No, most FBS4 operations are performed without opening the module. This preserves the module seals and warranty.
Which Mercedes models use FBS4?
FBS4 is used on 2016 onwards Mercedes models including A-Class W177, B-Class W247, C-Class W205 facelift/W206, E-Class W213 facelift/W214, S-Class W223, and all latest GLA, GLB, GLC, GLE, GLS models.
Can you program hybrid and electric Mercedes modules?
Yes, we support FBS4 programming for hybrid and electric vehicle control units including INV20EM01, EM01, and EM02 modules.
How long does FBS4 programming take?
Most FBS4 programming jobs are completed in 2-4 hours depending on the module type and complexity of the work required.
