Programming procedures
What the job needs
- Add a key: 1 existing working key required.
- All keys lost: no existing working key needed.
- PIN / security code: required — ZenZefi cert per ECU.
- Online / server access: required — ZenZefi cert online.
- On-board (no tool) sequence: not available — 2022-2025 W206 has no DIY onboard programming. Mercedes XENTRY / DTS Monaco dealer relearn with valid ZenZefi certificates (6 types per ECU) is the guaranteed path. Aftermarket Add Key without ZenZefi cert is not reliably supported as of 2026-05-23 — Autel IMKPA + G-Box3 published coverage stops at ~2021 MY pre-NTG7.
- On site: engine on · BEV READY + 13V aux · Clear EIS + NTG7 DTCs.
- Bring: Photo ID + vehicle registration. Title strongly recommended. ZenZefi-equipped locksmith log entry or Mercedes dealer service order.

Notes & cautions
- This chassis (EQE EV V295, 2023-2025) is Mercedes EQ-series MBUX 2/3 era luxury BEV with NTG7 secure-gateway architecture and IYZMS5I FCC. EQE shares EVA2 EV platform with EQS (V297) and uses same key + EIS architecture as W206 sedan. EV ignition path: brake + START → READY (no engine crank), but EIS/IMMO auth chain identical. Heavy dealer-bound XENTRY ZenZefi cert gate.
- XENTRY ZenZefi certificates required per ECU + per type — same gate as W206 sedan and EQS. MB SD Connect C6 / Star C6 + DTS Monaco 9.02 dealer-grade rig. Aftermarket tools do NOT carry valid ZenZefi certs as of 2026-05-23. EVA2 platform luxury sedan adds Hyperscreen MBUX optional + Digital Key (Apple Wallet) for some 2024+ builds — owner-managed alternative to physical key on supported builds.
- Verify trim before quoting — EQE 350 / EQE 350+ 4MATIC / EQE 500 4MATIC / AMG EQE 53 4MATIC+ all share V295 EV NTG7 architecture. AMG EQE 53 adds AMG-specific SCN coding requirements post-AKL. 2024+ EQE may support Digital Key (Apple Wallet, phone-as-key) via OTA — Digital Key is OWNER-managed via Mercedes me app, separate path from physical key.
- AKL on this chassis (W206 MBUX) is heavily dealer-bound as of 2026-05-23. ZenZefi certificates per ECU + NTG7 gateway authorization required. Aftermarket AKL coverage on W206 is not in primary published coverage of Autel/Xhorse/Lonsdor/OBDSTAR/AutoProPad. Customer should be referred to Mercedes service for AKL on W206 unless a ZenZefi-equipped specialist locksmith is available.
- Mercedes dealer AKL on W206 NTG7: full XENTRY session at MB-authorized service with valid ZenZefi cert chain. Cost typically 4-8x what an aftermarket locksmith charges on pre-2022 FBS4 BGA chassis. Customer should be advised of cost reality before scheduling.
- Verify trim before quoting AKL: EQE 350 / EQE 350+ 4MATIC / EQE 500 4MATIC / AMG EQE 53 all share V295 EV NTG7 architecture. AKL on BEV adds high-voltage battery pre-conditioning step at XENTRY. AMG EQE 53 has stricter SCN coding post-AKL.
