Mercedes E-Class Key Replacement
Mercedes E-Classs have been on Dallas–Fort Worth roads since the 1996 era, and across 4 key generations this model has used 3 different key systems — ir remote / metal transponder key; chrome smartkey / keyless go; 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 E-Class Keys
The table below is our verified key reference for the Mercedes E-Class — 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 |
|---|---|---|---|---|
| E-Class (W210) | 1996–2002 | IR remote / metal transponder key | DAS / DAS 2a–2b | Metal (pre-HU64) |
| E-Class (W211) | 2003–2009 | Chrome SmartKey / Keyless Go | FBS3 | HU64 |
| E-Class (W212) | 2010–2016 | Chrome SmartKey / Keyless Go | FBS3 → FBS4 (confirm by VIN) | HU64 |
| E-Class (W213) | 2017–2023 | 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 E-Class specifically, the immobilizer families we see are: DAS / DAS 2a–2b, FBS3, FBS3 → FBS4 (confirm by VIN), 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.
Which key does your year have?
- 1996–2002: IR remote / metal transponder key — DAS / DAS 2a–2b (Metal (pre-HU64))

- 2010–2016: Chrome SmartKey / Keyless Go — FBS3 → FBS4 (confirm by VIN) (HU64)
- 2017–2023: SmartKey / Keyless Go — FBS4 (HU64)

Mercedes E-Class Key FAQ
I lost the only key to my E-Class. 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 E-Class call.
My E-Class is push-to-start. Can you really program that outside the dealer?
Yes. Late-model E-Classs (2017–2023) use a proximity smart key on the FBS4 system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My E-Class is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1996–2002 generation (ir remote / metal transponder key), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
How fast can you reach my E-Class in DFW?
