What Owners Say

★ 4.9 · 847 verified reviews

— Marcus T., E 450 owner

FAQ

Common Questions

How much does Mercedes car key replacement cost?

Most jobs land between $249 (spare smart key) and $899 (all-keys-lost on newer FBS4 models). EIS repairs can push higher. You get a firm quote before we dispatch — no upcharges on-site.

Can you make a Mercedes key without the original?

Yes. We perform all-keys-lost service on every Mercedes from 1995–2026, including FBS3 and FBS4. We read the EIS, cut to your VIN, and program the new key on the spot.

How long does the replacement take?

Spare keys: 30–60 minutes. All-keys-lost: 60–120 minutes on most models. We arrive with everything needed to finish on the first visit.

Do you cover the newest models (W223, W206, EQS, EQE)?

Yes. We carry licensed FBS4 equipment and OEM-grade blanks for the entire current lineup including Sprinter VS30.

Will this void my Mercedes warranty?

No. We use OEM-grade keys and licensed manufacturer programming. Your factory and extended warranties remain intact.

What if my Mercedes won't start at all?

Usually an EIS (Electronic Ignition Switch) failure — extremely common on W203, W211, W209, W164, W204. We diagnose, repair, and pair a working key in one visit.

Do you really run 24/7?

Yes. Dispatch is live every day of the year. Emergency response averages under 45 minutes in most metros.
