What do Mercedes-Benz owners in Marina del Rey usually need?
Marina del Rey is almost entirely multifamily. Large apartment complexes from the 1960s and 1970s, waterfront condominium towers and newer luxury rental buildings ring the harbor basins, and there are very few single-family homes. For a car owner, that means the vehicle usually lives in a shared parking garage or a controlled-access lot rather than a driveway beside the front door. That reality shapes the Mercedes key calls we take.
The problems themselves are ordinary ones. A fob battery dies, the remote buttons go first, and then a Keyless-Go car starts reporting that the key is not detected. A SmartKey that has been used every day for years stops syncing. A Chrome-key shell cracks, a button wears through, or an emergency blade snaps. Sometimes the key is simply gone. And sometimes the key is fine and the car is the problem: on certain C-Class and E-Class chassis a failed electronic steering lock lets the dash wake up while the key refuses to turn, which looks exactly like a worn key.
Where lockouts happen here is worth saying plainly. In a big complex you can be standing at the car in the garage with the spare key upstairs, behind a controlled-access lobby and a gate you may not want to walk back through. If the car is parked somewhere along the harbor and the key is locked inside, we come to wherever the car is. If you only need the door opened, our Marina del Rey car lockout service covers that without making a new key at all.
Whatever the symptom, the first thing we ask is the model year and model. On a Mercedes, that single fact decides what is possible, how it is done and whether we are the right call or the dealer is.
How does mobile Mercedes-Benz key service work at the curb?
We run mobile service vans out of our Westwood storefront at 10740 Wilshire Blvd, and Marina del Rey is about 9 miles from that base. The work happens where the car is parked. You do not have to tow a Mercedes anywhere to get a key made, provided it is a car we can actually serve. Here is the order we follow.
- You call (213) 577-1366. A person answers at any hour, any day of the year. Tell us the model, the model year, what happened and where the car is.
- We sort out which key system the car uses. For most cars the year and model are enough. For late-production cars near a system changeover, we confirm by VIN rather than guess.
- If the car is a candidate for locksmith work, we say so and explain what we will do. If it is a dealer-only case, we tell you that on the phone, before anyone drives out.
- On arrival we check ownership. You will need to show that the car is yours, with identification and registration or title that matches the vehicle.
- Our technician reads the electronic ignition over infrared or through the OBD port, calculates the key password through professional equipment, and generates the new key. On certain chassis a steering-lock emulator is needed as part of an all-keys-lost job.
- We test everything before we leave: starting the car, the remote functions, the emergency blade and, on cars that have it, keyless entry.

Call (213) 577-1366Which Mercedes key do you have? Key eras in plain terms
Every Mercedes we deal with uses an electronic SmartKey rather than a conventional transponder key. That matters, because the key and the car exchange rolling codes over infrared. There is not a simple chip inside that can be cloned the way you would copy a basic key. What changes from one era to the next is how the key is coded and who can make a new one.
The older system is called FBS3 (the electronic ignition is called the EIS or EZS). It covers cars from the late 1990s through roughly 2014. The key is the familiar Chrome key or black SmartKey that you insert into the ignition and twist. Cars from about 2000 to 2014 on this system are fully serviceable by specialist locksmiths with the right tools.
The newer system is FBS4. Mercedes moved to it on a rolling, model-by-model schedule:
- Facelifted W212 E-Class, from April 2013 production
- CLA and GLA (models 117 and 156), from November 2014
- 2014 S-Class (W222), from launch
- 2015 C-Class (W205), from launch
- 2016 GLC (X253), from launch
- 2017 E-Class (W213), from launch
Why a late W166 gets checked by VIN
Most W166 ML and GLE models stayed on FBS3 through the end of production in 2019. However, a Mercedes fallback-process bulletin lists model 166 from July 2013 production among vehicles that can be FBS4. So we do not assume. A W166 built in that window gets confirmed against its VIN before we promise anything.
FBS4 cars generally pair with standard push-button start, and their keys are coded to the VIN at the factory. That factory coding is the reason the next two sections exist: it is the line between a job we can do in a parking space and a job that has to go through Mercedes.
What if you have lost every key to your Mercedes?
All keys lost is the situation people dread, and the honest answer depends on the system.
On an FBS3 car, all keys lost is routine for a specialist. We read the electronic ignition, calculate the key password online, and generate a new key. On the W204 C-Class, the W207 and the pre-facelift W212 E-Class, we also need an ESL or ELV steering-lock emulator as part of the process, because those chassis tie the steering lock into the procedure. That adds to the work and is part of why we want the exact chassis before we come.
On an FBS4 car, the picture is different and we will not dress it up. These cars are effectively dealer-only for added or replacement keys. The key is ordered through Mercedes, pre-coded to your VIN, and you have to prove ownership. Mercedes' own service bulletin also requires the vehicle to be registered as present in Xentry Diagnostics before a key can be enabled or disabled. Expect a multi-day wait, and budget for it. Mercedes handles key security through its own dealer authorization process, not the locksmith routes familiar from some domestic brands.
Limited specialist capability for FBS4 is emerging, but it is not something we would ask you to count on. If you call about a 2016 GLC or a 2017 E-Class with no keys, we will tell you the dealer path is the realistic one. If you cannot easily move the car, ask us how a tow or flatbed to the dealer would work, and we can talk through it.

Call (213) 577-1366What affects the cost of a Mercedes-Benz key in Marina del Rey?
We do not quote numbers in a web page, because on a Mercedes the range between jobs is wide and an honest figure depends on facts we do not have until we know the car. Here is what moves the cost, in rough order of importance.
- Key system: FBS3 work is something we perform ourselves. FBS4 usually means a VIN-coded order through Mercedes, which has its own cost structure.
- Whether you have a working key: copying from a key that still works is simpler than all keys lost, which requires reading and re-learning the car's security.
- Chassis: W204, W207 and pre-facelift W212 cars need a steering-lock emulator on all-keys-lost jobs, which adds equipment and time.
- Key type: a plain replacement shell or battery is a small repair; a complete new SmartKey with a new programming procedure is not.
- Where the car is: a mobile call to a garage in Marina del Rey involves travel from Westwood, and late-night calls differ from daytime ones.
- Whether the real fault is the key: if a failed ignition or steering lock is behind the problem, a new key will not fix it, and we would rather find that out first than sell you one.
Dealer or locksmith: which is the fair choice?
Both have a place, and we would rather say that than pretend otherwise.
For an FBS4 car, the dealer is generally the route. Keys come pre-coded to the VIN through Mercedes, and the procedure runs through their diagnostics. We cannot shortcut that, and if we told you otherwise we would be selling you a wait. For a car under a warranty or service contract that depends on dealer-supplied parts, the dealer may also be the cleaner path.
For an FBS3 car, a specialist locksmith is often the more economical route and usually the faster one, partly because we come to the car. If you have no keys at all and the car is in a garage in Marina del Rey, not having to arrange a flatbed matters. That is the real advantage of mobile service, not any claim that we can do what Mercedes controls.
If you are unsure which category your car falls into, call and tell us the year, the model and, if you have it, the VIN. We will say which way it goes. For model-specific background, see our overview of Mercedes-Benz car keys, or car keys in general if you are comparing makes.
Why call Wilshire Lock & Key for a Mercedes key?
We have been in business since 1987, and we work from a real storefront on Wilshire Boulevard in Westwood as well as from mobile vans. When you call (213) 577-1366, you reach us, not a national call center passing your job to whoever is nearest. There is no dispatch middleman between you and the person doing the work.
David, the owner, is lead technician and oversees how we handle vehicle work. That includes the decision to turn a job down when it belongs at the dealer. A company that cannot say no to a job it cannot do is not one to trust with your keys.
One more point on credentials. California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith you are considering for that license number before they touch your car, and check it with the state. That applies to us as it does to anyone else you call.

Call (213) 577-1366Mercedes key service around Marina del Rey: neighborhoods and ZIP
Marina del Rey is an unincorporated community in Los Angeles County, with the ZIP code 90292. We serve all of it, from the Via Marina corridor and the Admiralty Way corridor to the Fisherman's Village area, Villa Marina and Mariners Village. We also take calls from adjacent areas on the City of LA side, including the Marina Peninsula near Venice and the Oxford Triangle.
Many of these addresses are large complexes with controlled-access lobbies, parking-garage gates and shared mailbox rooms. If your Mercedes is in a gated garage, tell us the building name and how guests get in, so we are not stuck at a gate when we arrive. If you can arrange a guest pass or meet us at the entrance, the job goes smoother. Cars left near Burton Chace Park, Waterside at Marina del Rey, Marina City Club or Yvonne B. Burke Park are just as reachable; give us the nearest address or cross street.
Salt air is part of life here. Immediately on the water, exterior deadbolts, gate latches, hinges and padlocks corrode faster than inland, and the marine layer keeps hardware damp on many mornings. That is why we also get calls here for corroded building hardware and dock-gate padlocks. Those are separate jobs from your car key, but if you need both done, one visit can cover them. Our general Marina del Rey locksmith page lists what else we do, and we also handle key fob replacement in Marina del Rey when only the remote has failed.
If you would rather start with the full car-key picture for the area, the page on car key replacement in Marina del Rey is the best place to begin. You can also contact us if you want to describe the situation in writing first.

Frequently asked questions
Can you replace a Mercedes-Benz key at my apartment garage in Marina del Rey?
Usually yes, if the car uses the older FBS3 system. We come to the car and do the work on site. If it is a newer FBS4 car, the key generally has to be ordered through Mercedes, and we will tell you that before you spend time waiting for a van.
How do I know whether my Mercedes is FBS3 or FBS4?
Model year and model get us most of the way. FBS3 covers roughly the late 1990s to 2014, while FBS4 began on a rolling schedule from 2013 and arrived from launch on the 2014 S-Class, 2015 C-Class, 2016 GLC and 2017 E-Class. Late W166 cars are confirmed by VIN, so have it ready.
Is a Mercedes key ever dealer-only?
Yes. FBS4 cars are effectively dealer-only for added or replacement keys. The key is ordered pre-coded to your VIN with proof of ownership, and the vehicle has to be registered in Xentry Diagnostics first. Expect a multi-day wait.
Can you make a Mercedes key if I have lost all of them?
On an FBS3 car, yes. We read the electronic ignition, calculate the key password and generate a new key. On W204, W207 and pre-facelift W212 chassis we also need a steering-lock emulator. On an FBS4 car, the dealer route is the realistic one.
My Mercedes key will not turn, but the dash lights up. Is the key bad?
Not necessarily. On the W204 C-Class and W207 or pre-facelift W212 E-Class, a failed electronic steering lock motor can mimic a bad key. We would diagnose it before selling you a new key, since replacing the key would not fix that fault.
My car says key not detected. Do I need a new key?
Often the fob battery is dead. Remote buttons usually fail first, then Keyless-Go cars report that the key is not detected. Try a fresh battery before anything else. If the message stays, the key may have worn out, and we can check it.
Do I need to prove I own the car?
Yes. Expect to show identification and registration or title matching the vehicle. We make keys only for the owner or someone clearly authorized by the owner, and the dealer requires the same proof for VIN-coded orders.
Is your locksmith company licensed by the state?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that number before work begins. Call (213) 577-1366 and ask us about it directly, then verify it with the state.
