Mercedes GLE Key Replacement
Mercedes GLEs have been on Dallas–Fort Worth roads since the 2016 era, and across 1 key generation this model has used 1 different key system — smartkey / keyless go. Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About GLE Keys
The table below is our verified key reference for the Mercedes GLE — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| GLE-Class (W166/W167) | 2016–2023 | SmartKey / Keyless Go | FBS4 | HU64 |
Security System & Immobilizer
Mercedes pairs its infrared SmartKey with the EIS/EZS ignition module under the FBS3 (and now FBS4) security scheme — the reason generic tools fail and dealer quotes run high. Our Mercedes-capable equipment programs FBS3 keys on-site.
On the GLE specifically, the immobilizer families we see are: FBS4. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Mercedes GLE Key FAQ
I lost the only key to my GLE. 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 — this is our most common GLE call.
My GLE is push-to-start. Can you really program that outside the dealer?
Yes. Late-model GLEs (2016–2023) use a proximity smart key on the FBS4 system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
How fast can you reach my GLE in DFW?
