Mercedes key replacement in San Diego is often a dealer job on current models. Mercedes uses DAS, then FBS, then FBS4. The locksmith confirms whether their tools cover this VIN or the dealer must program. A locksmith still helps with lockouts, broken-key extraction, and many older SmartKey cars.
Swift Key San Diego is a referral service. Independent locksmiths say whether they can program your year, then set the price. Call (858) 400-4082. Swift Key does not program Mercedes keys.
Key types to confirm on this VIN
Ask the locksmith and the dealer which of these applies to your year, trim, and VIN.
- Chrome or silver blade with basic fob. Ask whether a locksmith with German-vehicle tools covers this car, or whether the dealer is the path.
- SmartKey (infrared, oval fob). Ask whether the shop has EZS support for this VIN.
- KEYLESS-GO / proximity. Newest proximity platforms can still be dealer-only. Confirm this VIN before assuming a locksmith can program it.
A working spare is still a simpler duplicate than all keys lost. If remotes are dead but the car starts, read key fob troubleshooting first.
Why Mercedes leans dealer
DAS (from 1995) uses infrared between the SmartKey and an IR receiver. Programming talks to the EZS (Electronic Ignition Switch), not only a generic OBD session.
FBS4 on newer cars requires Mercedes factory software and VIN-based verification. The store orders a blank cut to the VIN and programs it. That can take days if the blank is not in stock.
A shop that promises to program a 2020 GLE without dealer involvement deserves a second question.
What a locksmith can still do
Lockouts. Keys inside the car: opening the door is locksmith work. Start with car lockout, not a tow, if you only need in.
Broken blade in the door or ignition. Extraction tools, not a dealer parts order.
Pre-2015 SmartKey. Many C, E, S, GLK, and ML cars can be cut and programmed by a locksmith with German-vehicle diagnostics. It is slower than a Honda or Ford.
Triage. Year and VIN tell you locksmith, dealer, or mixed (open the door, then drive to Mercedes).
All keys lost
Pre-2015, when tools cover it: open, read EZS, cut, program, verify start.
When the locksmith cannot confirm coverage: Mercedes roadside or a tow to the dealer, with VIN, proof of ownership, and factory programming. Timeline is business days, not a driveway hour.

What to have ready
VIN on the door jamb or windshield. Mercedes blanks are VIN-specific. License and registration matching the owner.
Frequently asked questions
How much does Mercedes key replacement cost?
It tracks generation, AMG/S-Class hardware, and whether the dealer must order a blank. The locksmith or dealer quotes. Swift Key does not publish dollar figures.
Can Swift Key program a KEYLESS-GO fob?
No. Swift Key refers. The independent locksmith either does older SmartKey work or tells you to use Mercedes.
Call (858) 400-4082 for a referral match, a lockout, or extraction. For FBS4 programming, expect the dealer to own that step.
