How to order a new Mercedes replacement key

What do you need to order a new key? You don’t need the car with you or even your existing key. The dealer will order the right key for your car from the VIN. However, dealers strictly verify vehicle ownership.

If you are the current owner of the vehicle

• Find the nearest authorized Mercedes-Benz dealer.
• Get your current vehicle registration. If the vehicle is not currently registered, ask the dealer whether the original title is acceptable.
• Get your driver’s license, passport, or identity card.
• Head over to the dealer.
• Show them your documents and pay the quoted key and service charges. In some cases, new keys may cost up to $560, as reported by Mercedes-Benz owners.
• Availability and delivery time vary by model and VIN. Ask the dealer whether the key is available and when it can be activated.

If you are not the registered owner

• Bring the required ownership documents, plus the following items:
• A signed and dated authorization from the vehicle owner for which the key is being requested.

Tips for ordering and protecting your key

• Use a Silicone Key Fob cover for your Mercedes key to protect your key from accidental damage.
• If the key fob shell is damaged, consider replacing your Mercedes key shell with a replacement key shell. Our guide to the Mercedes key fob case upgrade shows the swap.
• For some models, you can order a WALLET KEY, which will unlock and start the car but doesn’t have the keyless door functions. Some older models may have a mechanical or limited-function key option. Ask the dealer what key types remain available for your VIN.
• Confirm the document requirements with the dealer before visiting. Many dealers require original documents.
• Each intelligent key uses a rolling code when it locks or unlocks your car. Mercedes-Benz electronic keys are coded for a specific vehicle. Used electronic keys generally cannot be reassigned to another VIN.
• If a key is lost or stolen, you can take your car to the dealer, and they can disable the lost key. The dealer can deactivate the electronic functions of a lost key, but its mechanical blade may still open the vehicle’s locks. Ask the dealer whether lock-cylinder replacement is appropriate if the key was stolen.
• Mercedes-Benz says that they need to synchronize the new key to the car. You can easily do that yourself. The key comes pre-programmed to your car and will start without further programming. The synchronization is more for the doors, windows, and unlock functions, which you can do yourself with our window and sunroof synchronization procedure.

Before ordering, rule out the cheaper possibility: if the key exists but nothing happens when you press it, see Mercedes key fob not working.
