Mercedes-Benz keys are coded by the manufacturer to your exact car, and for roughly 2015 and newer models, plus many earlier ones, that key can only be ordered through a Mercedes dealer against your VIN. We Do Locksmith tells Orlando owners that on the phone rather than in the driveway. What we do at the car: open it without damage, repair a cracked or water-damaged key shell, and get you moving while the ordered key is on its way.

The short answer
How to replace a Mercedes-Benz key in Orlando
The model year decides how a Mercedes-Benz key gets replaced. Mechanical keys from before about 1998 are cut at the car. Infrared FBS3 keys, about 1998 to 2014, can sometimes be made with specialist equipment and sometimes have to be coded by Mercedes; we check your chassis on the phone. Keyless-Go FBS4 keys, about 2015 onward, are ordered through a Mercedes dealer with your VIN and ID, which holds for every locksmith in Orlando. Whatever the year, the technician can get you into the car without damage and rebuild a broken key shell.
Which battery does a Mercedes-Benz key take?
The operator's manuals Mercedes printed for the 2012 SLK and the 2018 C-Class both call for one 3-volt CR2025 cell in the SmartKey. Press lock or unlock and watch the little check lamp on the key; if it stays dark, the cell is spent. A key that got soaked in a summer storm but has a good cell usually has a cracked shell or a corroded contact, and a repair fixes that without a dealer order.

Key types by year
Which Mercedes-Benz key do you have?
| Model years | Key type | What that means for replacement |
|---|---|---|
| Before about 1998 | Mechanical key, some with an early chip | Older W124, W140 and R129 cars take a cut key. We make it from the lock or the code at the car, and Mercedes is not involved at all. |
| About 1998 to 2014 (FBS3) | Infrared smart key, chrome or black | The key speaks to the ignition switch by infrared and is tied to the car's data card. Extra keys and some lost-key jobs can be done with specialist equipment; on many of these cars the honest route is still a key cut and coded by Mercedes to the VIN. We check the year and chassis on the phone and say which. |
| About 2015 onward (FBS4) | Keyless-Go smart key | Key generation is held by Mercedes-Benz. A replacement is ordered by the dealer against your VIN and ID. We handle the lockout, repair the existing key and, if the car will not be moving today, tell you before you pay for a visit. |
How Mercedes-Benz key programming works
Every Mercedes key is coded to the electronic ignition switch with data that the manufacturer keeps. That is why we do not promise a same-day Mercedes key on the phone. For FBS3 cars the technician can assess whether an on-site key is realistic or whether the dealer order is faster and cheaper. For FBS4 cars the key comes from the dealer, full stop, and we say so before anyone drives. Either way, the lockout, the shell repair and the trip to get you into the car are priced like any other job, and the estimate on the phone is free.
Things to know before you call about a Mercedes-Benz
- A Mercedes key that quits after a Florida downpour or a drop on the garage floor usually has a cracked shell or a bad battery contact. Moving the electronics into a new shell keeps the coded key and skips the dealer order entirely.
- Anyone offering a same-day key for a 2016 or newer Mercedes at your driveway without mentioning the dealer is going to disappoint you. The manufacturer controls that key data, and no locksmith in Orlando can change that.
- Sprinter vans, including the ones badged Dodge or Freightliner before 2010, run Mercedes electronics. The same rules apply to the fleet Sprinters around the airport and the convention center.
What sets the price of a Mercedes-Benz key
Where the key can be made at the car it costs less than the dealer route. Where the dealer must supply the key, we do not charge you for a visit that cannot end in a working key; we open the car and fix what can be fixed, with a free estimate on the phone for each and no separate call-out fee.

Mercedes-Benz key questions
What does it cost to replace a Mercedes-Benz key in Orlando?
For 2015 and newer cars the key is a Mercedes part ordered by the dealer, so the dealer sets that price; our part is opening the car and repairing what can be repaired, each estimated free on the phone. On earlier models, the price follows the generation of the key and whether one still works. The cheapest outcome, a new cell or a new shell, is the one we look for before anything else.
Do I have to tow my Mercedes to the dealer for a new key?
Rarely. For most 2015 and newer cars the key itself is ordered by the dealer, but we open the car first, and Mercedes can usually deliver or program the ordered key. For older cars we may be able to make the key where it sits in Dr. Phillips or Lake Nona.
Can you unlock my Mercedes if I am locked out at the mall or a hotel?
Yes. Every Mercedes model year is opened at the car without damage, from the Mall at Millenia garage to an I-Drive valet lane. Asking costs nothing: the estimate on the phone is free.
My Mercedes key is cracked but still works. Is that fixable?
Yes. A new shell with your electronics moved over keeps the coded key alive and costs far less than an ordered key. Do it before the crack reaches the circuit board.
Lost your Mercedes-Benz key in Orlando?
