What do Mercedes-Benz owners in Burbank usually need?
Most Mercedes calls from Burbank fall into a few patterns. A key that has finally quit after years of daily use. A fob whose battery died, so the car now says the key isn't detected. A lockout in an apartment garage or on a street. Or a key that is simply gone, with no spare in the drawer. What happens next depends almost entirely on which Mercedes you drive, and that is the point of this page.
Where you park shapes the problem. Downtown Burbank and the Chandler Bikeway corridor have apartment complexes where cars sit in shared lots and garages, and a typical lockout there is a fob left on a kitchen counter upstairs. The Media District has large controlled-access complexes and office campuses, so a stuck or lost key can also mean getting past a gate. Hollywood Burbank Airport adds the traveler: someone back from a trip with luggage in hand who finds the fob dead or the key missing, a long way from any spare.
- A worn SmartKey that has stopped syncing or no longer turns in the ignition
- A dead fob battery on a Keyless-Go car that now reports 'key not detected'
- A cracked Chrome-key shell, worn buttons, or a broken emergency blade
- A lockout with the key inside, covered separately under car lockout service in Burbank
- A lost key, with or without a spare, which we cover below under all keys lost
How does mobile Mercedes-Benz key service work at the curb?
We run mobile service vans out of our Westwood storefront, and Burbank is about 16 miles from that base. The work happens where the car is parked, whether that's a driveway, an apartment garage, or the airport side of town. Here is the order we follow.
- Call (213) 577-1366. The line is answered around the clock, every day of the year. Tell us the model, the year, and what happened.
- Have your VIN ready. It's on your registration and insurance card, and on the car itself. Mercedes changed key systems on a model-by-model schedule, and the VIN is how we settle which system your car uses.
- We tell you which side of the line you're on. If your car uses the older FBS3 system, we can usually do the work on site. If it uses FBS4, we say plainly that it's a dealer order and don't send a van for nothing.
- For serviceable cars, we confirm you own the vehicle, then connect professional key tools to the electronic ignition (the EIS/EZS) over infrared or the OBD port. The key password is calculated online and a new key is generated.
- On W204 C-Class, W207, and pre-facelift W212 E-Class cars, a steering-lock emulator (ESL/ELV) is needed for some jobs. We bring it and tell you when it applies.
- We test the new key: it starts the car, the remote functions work, and the car accepts it cleanly. If you still have an original key, we talk through making a spare while we're there, since that's the lighter-cost moment to do it.

Call (213) 577-1366Which Mercedes-Benz key do you have? Key eras in plain terms
Every Mercedes in our data uses an electronic SmartKey rather than a conventional transponder key. That matters, because there is no simple chip to clone the way there is on some other brands. The key and the car talk to each other with coded signals, and which system your car uses decides who can make you a key.
From the late 1990s through roughly 2014, Mercedes used the system known as DAS3/FBS3. This is the familiar infrared 'Chrome key' or black SmartKey that inserts into the electronic ignition and twists. The key and the car exchange rolling codes over infrared.
Mercedes then moved to FBS4 on a rolling, per-model schedule. The facelifted W212 E-Class switched from April 2013 production, and the CLA and GLA (models 117 and 156) from November 2014. Newer platforms came with it from launch: the 2014 S-Class (W222), 2015 C-Class (W205), 2016 GLC (X253), and 2017 E-Class (W213). FBS4 cars generally pair with standard push-button start, and their keys are coded to the VIN at the factory.
The W166 ML and GLE is the tricky one. Most stayed FBS3 through the end of production in 2019, but a Mercedes service bulletin lists model 166 from July 2013 production among cars that can be FBS4. So with late cars we confirm by VIN rather than guess. A wrong guess costs you a wasted trip or a wrongly ordered key, and we'd rather check first.
What if you've lost every Mercedes-Benz key?
On an FBS3 car, all keys lost is a job we can do. The tools read the electronic ignition over infrared or OBD, calculate the key password online, and generate a new key from scratch. There is no spare to copy from, so it takes longer than adding a key, but it doesn't require towing the car anywhere. On W204, W207, and pre-facelift W212 chassis, the steering-lock emulator is part of the job.
On an FBS4 car, the honest answer is different. Replacement keys are ordered pre-coded to the VIN through Mercedes, with proof of ownership. Mercedes' own bulletin also requires the car to be registered as present in its Xentry diagnostic system before a key can be enabled, so the car has to be with the dealer. Expect a multi-day wait, and plan around it. Some specialists are developing limited FBS4 capability, but it isn't something to count on, and we won't promise it.
Our process for lost keys, step by step, is laid out on our lost car key replacement page for Burbank. If you're not sure which Mercedes system you have, call and we'll work it out from the VIN.

Call (213) 577-1366Is it really the key? Common Mercedes-Benz problems
A key that won't turn doesn't always mean a bad key. On W204 C-Class and on W207 and pre-facelift W212 E-Class cars, the electronic steering lock (ESL/ELV) motor can fail. The dash wakes up, the key goes in, and it won't turn, which looks exactly like a worn key. Replacing the key in that case fixes nothing. Failed or worn electronic ignition units (EIS/EZS) can also cause a key to go unrecognized.
We diagnose before cutting anything, because a new key sold for a steering-lock fault is money wasted. Smaller fixes come first when they fit: a fresh fob battery often clears 'key not detected' on Keyless-Go cars, and a cracked Chrome-key shell or a broken emergency blade can often be repaired without a whole new key. For remotes that have worn out or stopped working, see our key fob replacement service in Burbank.
What affects the cost of a Mercedes-Benz key in Burbank?
We don't quote numbers on a web page, because the honest price depends on facts we can only get from your car. These are the factors that move it:
- Which system the car uses. FBS3 work can be done by a specialist; FBS4 means a dealer order, and the dealer sets that cost.
- Whether you have a working key. Adding a spare from an existing key is usually the more economical route compared with all keys lost.
- The chassis. Cars that need the steering-lock emulator involve extra equipment and labor.
- Whether the problem is the key at all. A battery, a shell, or a failed steering-lock motor each leads to a different repair.
- Key type. A Chrome key, a black SmartKey, and a push-button-start key are different parts.
- Time and place. Evenings, weekends, and holidays differ from a daytime booking, and some locations take longer to reach.
- Whether the car can be moved. A car that's stuck in a gated garage or a tight space may take extra effort.
Dealer or Wilshire Lock & Key: which makes sense?
Both have a place, and we'll say which one fits your car. For FBS4 Mercedes (roughly 2015 onward, and earlier on some models), the dealer is the right route for an added or replacement key. We can't do it, and we'd rather tell you now than waste your time. Bring proof of ownership, order the VIN-coded key, and plan for the multi-day wait.
For FBS3 cars, roughly 2000 to 2014 plus most GLE/W166 through 2019 once confirmed by VIN, a specialist locksmith is a sound choice. We come to you, so the car doesn't need a tow, and the same visit can include a spare key. You also skip the scheduling gap of getting a car to a service department when you're stranded.
Whichever way you go, ask any locksmith for their California BSIS locksmith company (LCO) license number. The state requires locksmith companies to hold that license, and a legitimate shop will give it to you without fuss. If you want to compare brands, our Mercedes-Benz key guide and general car key overview go into more detail.

Mercedes-Benz key service across Burbank
Burbank spans ZIP codes 91501, 91502, 91504, 91505, and 91506, and the housing varies in ways that affect cars. Magnolia Park's 1920s-1940s bungalows and the postwar ranch homes across the flats often mean driveway or street parking. The hillside houses above Glenoaks Boulevard in the Verdugo foothills can mean steeper, tighter access, so tell us at the start if the car is on a slope or a narrow drive. The Rancho District keeps equestrian-zoned single-family lots, usually with more room to work.
Downtown Burbank and the Media District have mid-rise condos and large controlled-access apartment complexes, where the car may be behind a gate or in a garage. Give us the gate code or arrange a contact in advance. Along the Chandler Bikeway, apartment parking is common. The Golden State District, Northwest District, and the South San Fernando Boulevard district are part of our service area as well.
We also handle the other locks in your life here, from vintage mid-century hardware on older homes to storefront locks along Magnolia Boulevard and San Fernando Boulevard. For the full range of car key service in the city, see car key replacement in Burbank, or contact us with your car details.

Frequently asked questions
Can you make a Mercedes-Benz key at my car in Burbank?
For FBS3 cars (roughly 2000-2014, plus most GLE/W166 through 2019 once confirmed by VIN), usually yes. We bring professional tools to the car and program the key on site. For FBS4 cars, we can't, and we tell you so on the call.
How do I know whether my Mercedes is FBS3 or FBS4?
It depends on model and production date, so we confirm by VIN. As a rough guide, facelifted W212 E-Class from April 2013, CLA/GLA from November 2014, and the W222, W205, X253, and W213 from launch are FBS4. Some late W166 cars may be too, so we check rather than assume.
I lost my only key. Can that be fixed?
On FBS3 cars, yes. We generate a new key without any existing key, using an emulator on some chassis. On FBS4 cars, a VIN-coded key must be ordered through Mercedes with proof of ownership, and you should expect a multi-day wait.
Why can't a locksmith program every newer Mercedes?
FBS4 keys are coded to the VIN at the factory, and Mercedes requires the car to be registered in its Xentry diagnostics before a key can be enabled. Limited specialist capability is emerging, but we don't promise it.
My key won't turn but the dash lights up. Is it a bad key?
Not necessarily. On W204 C-Class and W207 or pre-facelift W212 E-Class cars, a failed electronic steering lock motor causes exactly this. We diagnose before cutting a key so you don't pay for the wrong fix.
My Mercedes says 'key not detected'. What should I try?
On Keyless-Go cars, a dead fob battery is a common cause, and the remote buttons usually fade first. A new battery may fix it. If not, the fob may be worn out and need replacing, which we can look at.
Do you come to Hollywood Burbank Airport?
Yes, we serve travelers whose Mercedes key is lost or dead while parked at the airport. Call (213) 577-1366 with the car's year, model, and VIN so we can tell you whether it's something we can do on site.
Are you licensed to do this work?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before work starts. Our license number is being added to this site, so call and ask if you need it.
