Mercedes-Benz key replacement in Van Nuys

What do Mercedes-Benz owners in Van Nuys usually need?

Van Nuys is a neighborhood where a lot of cars live on the street, in apartment carports, or in shared lots rather than in private garages. The flats are mostly postwar bungalow and ranch tracts, and the main corridors, Sepulveda, Kester and Victory, are lined with 1960s-80s garden apartments and dingbat-style multifamily buildings. The area has a high renter share. For a Mercedes owner, that tends to mean the car sits wherever the building put it, and if there is only one key, that one key does all the work until the day it stops.

Then there is the airport side of the neighborhood. Van Nuys Airport and the FlyAway bus terminal bring people who leave a car for a few days and come back to a fob that no longer responds. Around the Civic Center, people park for a full workday and walk back to a key that suddenly will not start the car. Those are the situations where a mobile locksmith earns its keep, because the car is where it is and it is not going anywhere on its own.

Here is what we are typically asked to deal with on Mercedes-Benz vehicles:

• A spare key made while you still have a working one, which is almost always the easier and more economical situation than starting from nothing
• A dead fob battery: the remote buttons go first, then Keyless-Go cars start reporting 'key not detected'
• A SmartKey worn out from years of daily use that no longer syncs with the car
• A cracked Chrome-key shell, worn buttons, or a broken emergency blade
• A key that will not turn in the ignition, which can be the key, the EIS/EZS, or the electronic steering lock
• Every key lost, with no spare to work from

How does mobile Mercedes-Benz key service work at the curb?

We come to the car. Our vans are dispatched from the same company that runs the storefront at 10740 Wilshire Blvd in Westwood, about 12 miles from Van Nuys, so you are talking to one outfit from the first call to the finished key, not a dispatcher handing your job to whoever is free. The phone is answered around the clock, every day of the year, at (213) 577-1366.

The most important step happens before anyone drives anywhere, and that is working out which system your car uses. Mercedes does not switch systems on a clean calendar line, so the model, the year and, for some cars, the VIN all matter. Getting that right on the phone saves you from a wasted visit or from a promise we could not keep.

1. Call (213) 577-1366 and tell us the model, the approximate year, where the car is parked, and whether you have any working key at all.
2. We work out which side of the line your car likely falls on: the older infrared FBS3 system, which a specialist can service, or the newer FBS4 system, which is effectively dealer-only. Where the model is a borderline case, we say so and confirm by VIN.
3. If your car is serviceable, we come to you in Van Nuys, whether that is a driveway, an apartment lot, a curb or an office parking structure.
4. We ask for proof that the car is yours and check the VIN against the car.
5. We read the EIS/EZS, either over infrared or through the OBD port, and generate the new key with professional tooling in the class of Xhorse VVDI MB, Abrites and Autel IM-series equipment.
6. We test the key: it has to start the car, lock and unlock it, and work the way a factory key should, before we call the job finished. If the car needs a steering-lock emulator for an all-keys-lost job, we deal with that as part of the work and explain it as we go.

Which Mercedes key do you have? Key eras in plain terms

Every Mercedes in the data we work from uses an electronic key, not a conventional transponder chip like the ones on some other brands. That matters, because it changes what a locksmith can and cannot do. Here is the short version, split into the two systems you will hear about.

The older system is called FBS3 (the lock side is the DAS3 era). From the late 1990s through roughly 2014, the key is the familiar infrared 'Chrome key' or black SmartKey that inserts into the EIS/EZS electronic ignition and twists. The key and the car trade rolling codes over infrared, so there is no clone-able chip in the way a locksmith might copy a Toyota key. New keys are generated by reading the car's electronics and calculating the key password online, not by copying.

The newer system is FBS4, and Mercedes moved to it on a rolling, model-by-model schedule rather than all at once. The dates we have are these:

• Facelifted W212 E-Class: from April 2013 production
• CLA and GLA (models 117 and 156): from November 2014
• 2014 S-Class (W222), 2015 C-Class (W205), 2016 GLC (X253) and 2017 E-Class (W213): FBS4 from launch
• Most W166 ML/GLE cars 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 late ones are confirmed by VIN and never assumed

What does that mean for a Van Nuys owner in practice?

If your car is a FBS3 car, roughly 2000 to 2014, plus most GLE/W166 cars confirmed as FBS3 by VIN, a specialist locksmith can handle it, including cases where every key is gone. That is the work we do at the curb.

If your car is FBS4, roughly 2015 onward and earlier on some models, FBS4 cars generally pair with standard push-button start, and the keys are coded to the VIN at the factory. Added or replacement keys are effectively dealer-only. Some specialists are developing limited FBS4 capability, but it is not something we would ask you to count on, and we would rather tell you that on the phone than after a drive across the Valley.

If you are not sure which side your car is on, that is a normal question. Give us the model and year, and the VIN if you can read it off the dash or the door jamb, and we will tell you straight.

What if you've lost every Mercedes key?

All keys lost is the hardest version of this job, and it is worth being honest about how it plays out, because the answer depends almost entirely on which system the car has.

On a FBS3 car, all keys lost is serviceable. We read the EIS/EZS, calculate the key password online and generate a new key from scratch. On the W204 C-Class, the W207 and the pre-facelift W212 E-Class, an ESL/ELV steering-lock emulator is needed as part of the job, which adds a step and some time, and we plan for it from the start.

On a FBS4 car, a lost key means a VIN-coded order through Mercedes with proof of ownership. Mercedes' own service bulletin 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, including how you will get to work in the meantime. Anyone who tells you it can be done in an hour at the curb on a 2016 GLC is not being straight with you.

If you are in the middle of it right now, our page on lost car key replacement in Van Nuys covers the general process, and the Mercedes-Benz key overview covers the brand more broadly.

Is it the key, or is it the car? Common Mercedes problems

Not every Mercedes key problem is a key problem, and it is worth knowing before you pay for a new one. The data we work from points to a few patterns that show up again and again:

• A failed or worn EIS/EZS electronic ignition: the key is not recognized or will not turn
• An electronic steering-lock (ESL/ELV) motor failure on the W204 C-Class and the W207 and pre-facelift W212 E-Class: the dash wakes up, but the key will not turn, which looks exactly like a bad key
• A SmartKey that has worn out after years of daily use and stopped syncing
• A dead fob battery, which usually comes before anything more serious
• A cracked Chrome-key shell, worn buttons, or a snapped emergency blade

What affects the cost of Mercedes-Benz key replacement in Van Nuys?

We do not quote numbers in a web page, because the honest answer depends on the car in front of us. These are the things that move the cost, roughly from most to least significant:

• Which system the car has. A FBS3 key is generated by a specialist; a FBS4 key is ordered pre-coded from Mercedes, which is a different process with a different cost structure and a longer wait.
• Whether you have a working key. Making a spare from a working key is usually the more economical route; all keys lost takes more work.
• Whether a steering-lock emulator is needed, as it can be on the W204, W207 and pre-facelift W212 chassis in an all-keys-lost job.
• Whether the problem is the key at all. A fob battery or a cracked shell is a smaller repair than a failed EIS/EZS or a failed steering-lock motor.
• The model and year, which determines the key type and the programming route.
• Where and when you need us. A van visit to your Van Nuys address in the middle of the night is a different job from a planned appointment at the storefront.

Dealer or Wilshire Lock & Key: which makes sense?

For a FBS3 car, a specialist locksmith can usually do the job at your car, which means no tow, no waiting room, and no leaving the car at a service department. For all keys lost, that difference matters most, because the car does not have to move before the key exists.

For a FBS4 car, the dealer route is the realistic one right now, and we say so. Keys are ordered pre-coded to the VIN through Mercedes with proof of ownership, and the dealer has the Xentry authorization process. Where we can still be useful is the practical stuff: confirming that your car really is FBS4 before you commit to a wait, sorting out a dead fob battery, a cracked shell or a broken emergency blade, or helping if you are locked out in the meantime through our car lockout service in Van Nuys.

A fair rule: if a locksmith promises to program a FBS4 key on the spot without asking you for the VIN, ask a few more questions.

Why call Wilshire Lock & Key?

We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. David, who owns the company and leads the technical work, oversees how jobs are done. We have a storefront on Wilshire Boulevard in Westwood and mobile service vans, and you get one company from the first phone call to the finished key. There is no dispatch middleman between you and the person doing the work.

California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work on your car. That is a reasonable thing to ask of us, too, and you should ask it of anyone who shows up at your curb.

Mercedes-Benz key service across Van Nuys neighborhoods and ZIP codes

Van Nuys covers a lot of ground, and our vans work across ZIP codes 91401, 91405, 91406 and 91411. The places people tend to need us fall into a handful of patterns.

Along the Sepulveda Boulevard corridor and in the Kester Avenue area, the multifamily buildings are mostly 1960s-80s garden apartments and dingbats, with parking that is tight and shared. Rental turnover is common, and that is when a Mercedes owner realizes the second key never made it out of the last move. Near the Van Nuys Civic Center, the long parking day is the usual story, and along the Van Nuys Boulevard and Victory Boulevard corridors it is a mix of residents and people running a small business. Around the Van Nuys Airport district and the Raymer Street industrial district, we are often dealing with a car that has sat for several days, and with owners who need the car working before a flight, a shift or a deadline. The Sherman Way corridor and the FlyAway terminal are covered, too.

The same applies if you are not sure where to start. Our Van Nuys service area page covers the other services we do here, and if you would rather talk it through first, the contact page is there, though the phone at (213) 577-1366 is the fastest route, any hour of the day.
