The short answer
How to replace a Mercedes-Benz key in Jacksonville
It depends on the model year. Mechanical keys from before 1997 are cut at the car. On infrared FBS3 keys, roughly 1997 to 2014, we tell you on the phone whether we can make the key at the car or the dealer will be quicker. For Keyless-Go FBS4 cars, about 2015 onward, the dealer has to order the key using the VIN, and no locksmith can make it. On every year we open the car without damage in Jacksonville and fix a key that is cracked or has been wet.
Which battery does a Mercedes-Benz key take?
Mercedes names a single CR2025 coin cell for the SmartKey in both its 2012 SLK and 2018 C-Class operator's manuals. The key has a small battery check lamp: press lock or unlock, and if the lamp does not light briefly, the cell is flat. For any other model, read the type printed on the old cell before buying a new one.

Key types by year
Which Mercedes-Benz key do you have?
| Model years | Key type | What that means for replacement |
|---|---|---|
| Before 1997 | Metal key, some with early transponder | Older W124 and W140 cars use mechanical keys we cut from the lock or code. No dealer involvement. |
| 1997 to about 2014 (FBS3) | Infrared smart key (the chrome or black plastic key) | The key talks to the ignition by infrared and is coded to the car's data card. Additional keys and some lost-key jobs can be done with specialist equipment; many still require Mercedes to cut and code the key to the VIN. |
| About 2015 onward (FBS4) | Keyless-Go smart key | Key generation is locked to Mercedes-Benz. Replacement keys are ordered by the dealer against your VIN and ID. We can still open the car, repair a damaged key shell and handle the lockout. |
How Mercedes-Benz key programming works
Every Mercedes key is coded to the car's electronic ignition switch using data held by Mercedes-Benz. For older FBS3 cars our technicians can assess whether an on-site key or a dealer-ordered key is the faster and cheaper route; for FBS4 cars the key comes from the dealer, and we tell you that on the phone so you do not pay for a visit that cannot end in a working key.
Things to know before you call about a Mercedes-Benz
- If a Mercedes locksmith promises a same-day key for a 2016 or newer car without mentioning the dealer, be cautious; the manufacturer controls that key data.
- A Mercedes key that stops working after getting wet or dropped often has a damaged shell or battery contact, not a dead key; a repair is far cheaper than an ordered key.
- Sprinter vans sold as Dodge or Freightliner before 2010 use Mercedes systems too; the same rules apply.
What sets the price of a Mercedes-Benz key
Where we can make the key on site it costs less than the dealer route. Where the dealer must supply the key, we tell you before booking and give you a free estimate for just the lockout or key repair, so you are not paying twice.

Mercedes-Benz key questions
How much does a Mercedes key replacement cost in Jacksonville?
It turns on who can make the key. On FBS4 cars, about 2015 onward, only the dealer can supply the key, so that part is priced by Mercedes, and we charge only for what we do, such as the lockout or a shell repair. On older cars the key generation and whether you still have a working key set the price. A new battery or shell is always the least expensive fix, and we check for it first. Asking costs nothing: the estimate by phone is free.
Do I need to tow my Mercedes to the dealer for a key?
For most 2015 and newer models the key itself must be ordered through Mercedes, but you rarely need a tow: we open the car, and the dealer can often deliver or program the ordered key. For older models we may be able to make the key on site.
Can you open my Mercedes if I am locked out?
Yes. Lockouts on every Mercedes model year are done at the car without damage. Call first for a free estimate; there is no obligation.
My Mercedes key is cracked but works. Can you fix it?
Yes. We replace the shell and move the electronics over, which keeps your coded key working without ordering a new one.
