Electronic-key and parts availability review
Share the exact Mercedes-Benz model and year, trim if known, and whether the vehicle has an inserted key or another start arrangement. The supported models are established during that review; no blanket year or module range is claimed.
No. Hardware sourcing and the supported procedure need confirmation first; some requests may require a specialist or dealer.
Identify the key system
Depending on the vehicle, the request may involve a mechanical blade, a transponder, a remote-head key, a proximity fob, or separately managed digital access. We check the actual system instead of treating a similar-looking key as interchangeable.
What to send before an appointment
- Mercedes-Benz model year, model, trim if known, and ZIP Code.
- Whether the request is a spare, a replacement, all keys lost, or a remote problem.
- Whether a working key remains and which functions it provides.
- Part number or FCC ID for a proposed fob, plus whether it is new or used.
Customer-supplied keys & limitations
A supplied key is accepted only after compatibility review. Prior matching, locked electronics, incorrect parts, and vehicle restrictions can prevent reuse. Dealer-only procedures, connected accounts, and security-module work are not assumed to be supported.
Proof of ownership or documented authorization is required. Quote factors include compatible parts, cutting or matching, key count, all-keys-lost requirements, and the service location.
