What you should do when your Mercedes car key is lost and how to get a replacement:
- First, Make sure you don’t have a spare key. Many of us put one away as a backup for when we lose our key. Take a deep breath and try to remember where it is. Need some ideas of where your key might be? Take a look here
- In addition, if you decided to call an automotive locksmith, remember to provide the exact year, make, and model, e.g. “I lost my 2013 Mercedes-Benz CL car keys, I lost my 2019 Mercedes-Benz EQC push to start key” etc. This is important so the locksmith can check if he or she has the right key blank.
- Furthermore, remember to ask if the key needs to be programmed or coded, some models do – e.g., a replacement key for a 2012 Mercedes-Benz Sprinter transponder key fob will need to be programmed, while 1995 Mercedes-Benz E320 won’t.
- If you think you need a new ignition switch/ lock cylinder, first make sure you don’t simply need a new key. Changing the ignition for Mercedes cars is more expensive than buying a replacement key and it will mean that you will have one key for the doors and another for the ignition.
- When calling a dealer to get a Mercedes replacement key, ask if you can pick up the new key yourself, or whether you have to tow the car there.
- In addition, if the key won’t turn in the ignition, mention if this is something that has happened for the first time or is an ongoing problem.
- Moreover, if you have previously changed the ignition cylinder, tell the locksmith or dealer as it may prevent them from cutting you a new key by code.
- Finally, make sure you have the Vehicle Identification Number (VIN) of the car and relevant documents to show ownership of the car. The title certificate, registration papers, your ID and proof of insurance, etc.

Mercedes keys replacement near me – Things to remember before calling a locksmith or dealer
Calling an automotive locksmith or a dealer near your location when you need a key replacement is probably the most common thing to do. Based on your location, an automotive locksmith can come to you, or you may choose to tow the car to the dealer.
We outline a few points to remember, to help you save some time and money regardless of which option you choose:
- First, always ask for a quote. Describe the problem in detail and give the automotive locksmith all the details, even if you think they may not be relevant.
- Moreover, If the locksmith has all the details, it can speed up the process and make it more cost-effective. Remember to give them your exact location to prevent a long waiting period. It may also affect the price.
- In addition, tell the locksmith/dealer if the ignition was changed before, as far as you know. A previous ignition change may result in different keys for the ignition and doors.
- Most Mercedes models today are equipped with chips or transponders, so make sure you mention the exact year, make, and model and ask the locksmith if they have the necessary tools in their truck to code the key. Not all locksmiths have a key coding machine to program those keys.
- In addition, it’s important to have the VIN number available as the locksmith may need it.
- Finally, remember that for most Mercedes models, there is no need to tow the car to the dealer should you lose your car keys. You can try and call the AAA, or an automotive locksmith who should be able to make you a new car key on site.

A locksmith usually charges a service fee plus the cost of the parts and labor for a replacement key. Therefore, you should expect to pay more than the dealer would charge.
