Mercedes-Benz key replacement in Austin, TX — infrared smart keys done on-site

Mercedes-Benz uses an infrared smart key that talks to the EIS/EZS ignition module, so a replacement is far more involved than cutting a blank. Our Austin, TX European specialist originates and programs these keys at your location rather than sending you to a dealer.

Mercedes-Benz key replacement, programming and lockouts in Austin, TX

The EIS/EZS module stores a limited number of key slots. When a Mercedes key is lost, the correct approach is to write a new key to a free slot and disable the missing one — done properly, this preserves the vehicle's original security architecture.

Sprinter vans are a common commercial call in Austin, TX. A locked or lost Sprinter key can idle an entire delivery route, so we prioritise fleet dispatch and can cut spares for the rest of the fleet during the same visit.

FBS4 vehicles (roughly 2015 onward) are significantly more restricted than earlier generations. We tell you honestly on the phone whether your specific year and model can be completed mobile before dispatching a technician.

What's included

  • EIS/EZS key slots written correctly, lost key disabled
  • Sprinter and commercial fleet priority dispatch
  • Honest feasibility check on FBS4 vehicles before dispatch

Key types we program

  • Infrared smart key
  • Chrome key (FBS3)

FAQ

Mercedes-Benz key questions from Austin, TX drivers

How much does a Mercedes-Benz car key replacement cost in Austin, TX?

Most Mercedes-Benz keys we make in Austin run between $289 and $649 depending on whether you need a basic transponder key, a remote head key or a push-to-start proximity smart key. You get a firm, all-in price on the phone before a technician is dispatched — no surprise fees on arrival.

Can you make a Mercedes-Benz key if I lost all of my keys?

Yes. All-keys-lost origination is routine work for us. After we verify you own the vehicle with photo ID plus registration, title or insurance, we decode the key from the VIN, cut it in the van and program it to your Mercedes-Benz's immobiliser on-site.

Do I have to tow my Mercedes-Benz to the dealership?

No. We are a fully mobile Austin auto locksmith — the key machine, programming tools and blanks travel with the technician. We come to your driveway, office garage, H-E-B parking lot or roadside anywhere in Austin, TX, usually within 15–30 minutes.

Will you erase my old Mercedes-Benz keys?

Yes, on request we wipe every previously programmed key from the vehicle's memory so a lost or stolen Mercedes-Benz key cannot start your car again. This is included at no extra charge with any all-keys-lost job.
