Are you looking to get a new key made for your Mercedes Benz? Did you lose all of your keys? That’s ok. If you own a newer Mercedes-Benz, you don’t need the old keys to order a new Mercedes key. Just follow the instruction below on how to order a new Mercedes key. 

Keys for older Mercedes-Benz

We have learned that Mercedes-Benz no longer makes replacement keys for older models. Generally, if you own a pre-2000 Mercedes-Benz, you may have a hard time finding a replacement key. You should check with the dealer, but if they have discontinued keys for your car, here are your options.

Find a locksmith that specializes in European cars. They are more likely to have a device such as the AK500 programmer

Not all locksmiths can make Mercedes-Benz keys but in most major cities, you will find locksmiths who can make Mercedes-Benz keys.

How to order a new Mercedes replacement key

What do you need to order a new key? Well, 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 number. With that said, they are very strict on verifying ownership.

If you are the current owner of the vehicle:

  • Locate the closest Mercedes Benz dealer.  Click Here
  • Get your current vehicle registration. If not registered the original title will do.
  • Get your driver’s license or passport or identity card.
  • Head over to the dealer.
  • Show them your documents and pay the $200 to $300 for your new key. In some cases, new keys may cost up to $560, as reported by Mercedes-Benz owners.
  • Wait 3 to 4 days for the key to be shipped to your dealership. Keys are made in USA in some cases they have to be shipped from Germany in which case you may have to wait up to 10 days.

If you are NOT the current owner of the vehicle: 

  • All the required documents as if you were the owner of the car plus you will need:
  • A Signed and dated authorization from the owner of the vehicle for which the key is being requested.

TIPS: 

  • Use aMercedes key cover to protect you key from accidental damage.
  • If the key fob shell is damaged, consider replacing you Mercedes key shell with a new one.
  • For some models, you can order a WALLET KEY which will unlock and start the car but doesn’t have the door keyless functions. The wallet key is cheaper so check if this is available for your model.
  • Copies of the originals of the documents above are not accepted. They need to be originals.
  • Each smart key uses a rolling code each time it unlocks/locks your car. So you can’t just make a copy of the existing key.
  • If you lost a key and you are worried that it is in the wrong hands, you can take your car to the dealer and they can disable the lost key.
  • 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 it will start it without any further programming. The synchronization is more for the doors, windows, unlock function. Even those functions have worked for me every time without any further synchronization.

These steps work if you live in USA, Canada or any country if you have an authorized Mercedes Benz dealer near you.

  4. Mercedes discontinued 97 thru 2002 key replacements and wont give an option for you to start your car i have sl 500 mercedes and im so upset they gave no options for all these owners

  5. I Bought a 2004 C-240 2 months ago. Without a the key fob. The part that goes into the ignition switch is all I have. The remote control part is missing. How can I program the new one.

  6. Do you now where I can get a replacement key cover asap, the infrared cover at the tip of my key broke and the car won’t start.

  7. Lost my keys for a c220 CDI, Mercedes wanted £370 for a new one + Vat + recovery to dealer and my log book was inside glovebox after returning from France trip so they would not touch until replacement arrived I was looking at 7 – 10 days to get going again, got a guy to come to me same day and sort he was there 30 minutes and I have 2 keys for less than the dealers wanted for 1 key.

  8. I have a 1998 s420 and the only keys was lose, I went to the dealer but the key was discontinued are that don’t have any idea if or went this key will be made. Is there any other way to get a key for this car?

  9. I called the dealership today to have my moms key replaced after being lost. they are charging $420 to replace the key. Its a 1995 SL! The car itself it barely worth that. There has to be a cheaper way. Please help.

  10. I have a 1997 SL320, great car, but can’t drive it because I lost all the keys. Went to dealership, they tried to order replacement keys, but they didn’t work and then they said Mercedes told them they no longer make keys for my car. Seriously????? Mercedes has a monopoly on being the only company allowed to make the replacement keys and they stop making this one, some type of chip in the wallet key and the remote that only can be made by Mercedes or whoever supplies them.
    There must be other people out there with this problem! What can we do? Can someone help?
    Thank you

  11. Mercedes has discontinued the keyfob for my 1999 ML320.
    I can’t get replacement keys at all and they will not reprogram an old one.

    • You are right. I have a 2002 ML320 and MB discontinued the keyfob but they can cut you a key that can open your car manually and start your car. current cost is $45 plus tax. If the new key won’t turn the door lock, that’s because you have been using the remote and not the key for a long time. A little lube will work.

  12. My keys to my s500 mercedes benz were destroyed in a house fire what snd how is the cheapest way to replace my ignition key

  13. Our key is not working. Mercedes will not made another because there have been 8 keys made previously. Do you know have any ideas?

    • You may have to tow the car there. They should be able to remove one of the keys from the memory.

      • There is only one model (ML) for a 2 year period (98-99) that has the issue of 8 keys available. There is no way to remove one of those keys. The only option left on those vehicles is to replace the lock set, the ECU, and the AAM. This is not cheap. 3-4 thousand dollars for parts alone. I am a parts manager at a Mercedes-benz dealership. I know this to to be true 100%
