About EQS Keys
Verified key reference for the Mercedes EQS — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| EQS (V297) | 2022–2024 | SmartKey / Keyless Go | FBS4 | HU64 |
Security System & Immobilizer
Mercedes pairs its infrared SmartKey with the EIS/EZS module under FBS3 (now FBS4) — specialist equipment programs FBS3 keys on-site.
On the EQS specifically we see: FBS4. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Mercedes EQS Key FAQ
I lost the only key to my EQS. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site — no tow, no dealer wait.
My EQS is push-to-start — can you program that outside the dealer?
Yes. Late models (2022–2024) use a proximity smart key on FBS4 — we carry the fobs and the programmer, and we cut the emergency blade.
