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: No PIN — EIS + tokens.
- Online / server access: required — Cloud token req'd.
- On-board (no tool) sequence: not available — 2009-2015 X204 GLK has no DIY onboard programming. Mercedes XENTRY / DAS3 dealer relearn requires SCN coding certificate. Aftermarket Add Key requires VVDI MB Tool + W204/X204 EIS adapter + tokens OR Autel IM608 Pro II + IMKPA + G-Box3 OR CGDI MB.
- On site: engine off · 13V+ aux + charger · Clear EIS + DAS DTCs.
- Bring: Photo ID + vehicle registration. Title strongly recommended for AKL. VIN cross-check (W204 is widely-counterfeited body — verify VIN-stamp).

Notes & cautions
- This chassis (X204 GLK, 2009-2015) is Mercedes FBS3 NEC EIS era — compact crossover sibling of W204 C-Class. X204 shares W204 platform + EIS architecture: same EIS adapter cable workflow, same key PN family base. GLK350 / GLK250 BlueTEC / GLK63 AMG all on standard X204 EIS — no quirks.
- FBS3 NEC on this variant (X204 GLK) requires EITHER Autel IM608 Pro II + IMKPA + G-Box3 (OBD path) OR Xhorse VVDI MB Tool / Key Tool Plus + W204/X204 EIS adapter cable (shared SKU with W204 C-Class) OR CGDI MB. X204 is widely-supported on all major FBS3 aftermarket tools.
- X204 AKL is OBD-friendly on full 2009-2015 run. Bench EIS removal only needed for damaged-EIS. Crossover body — water ingress less common than W164/X164 SUVs but still verify EIS integrity before OBD attempt.
- AKL on this chassis erases all previously paired FBS3 keys. Bring minimum 2 new Mercedes FBS3 NEC keys matching trim FCC (IYZDC07 for 2009-2012 OR IYZDC11 for 2013-2015). Wrong FCC means scheduled job cannot start.
- X204 AKL is OBD-friendly compared to X253 GLC FBS4 — full 2009-2015 run supports OBD AKL via Autel IM608 + IMKPA + G-Box3 or Xhorse VVDI MB / Key Tool Plus + W204/X204 EIS cable. Bench EIS removal only for damaged-EIS scenarios.
- AKL erases EIS-paired remotes. Recovered old keys will not authenticate. Verify trim: GLK350 / GLK250 BlueTEC / GLK63 AMG all share X204 EIS architecture (same as W204). 2009-2012 early X204 with NEC-era Hella EIS may have minor password-calc differences vs 2013-2015 — IMKPA + Xhorse both auto-detect.
Lockout
Door pick / decode: Lishi HU64 (CCW).
