2023 Mercedes-Benz S-Class key replacement

The 2023 Mercedes-Benz S-Class typically uses a proximity smart key with push-to-start and keyless entry. We identify your exact key type, then cut and program a replacement so your vehicle starts, locks, and unlocks the way it should.

We come to you anywhere in Union City: your driveway, a parking lot, work, or roadside. With proof of ownership, we can even make keys when every key is lost.

Programming a modern key is precise work. Our mobile units carry the equipment to cut and code the correct key for your vehicle on site, which is why we can usually get you driving again without a tow.

2023 Mercedes-Benz S-Class key technology

The 2023 Mercedes-Benz S-Class generally relies on a proximity smart key with push-to-start and keyless entry. That matters because the replacement has to be both cut correctly and programmed to the vehicle — a hardware store copy alone will not start the engine on a chipped or proximity system.

Our mobile unit carries the equipment to handle proximity smart key work for the 2023 Mercedes-Benz S-Class in Union City, so you are not stuck waiting on a dealer appointment.

Keep proof of ownership handy. For any key replacement, especially all-keys-lost jobs, a professional locksmith will ask for documentation showing the vehicle is yours. It protects you against theft and is a sign you are dealing with a reputable pro.

Avoid a lockout: get a spare Mercedes-Benz key

A fob that suddenly stops working is not always dead. Sometimes it just needs a fresh battery or a new shell; other times it needs reprogramming. We can test which it is before assuming you need a full replacement.

The single best thing you can do to avoid a stressful, expensive day later is to make a spare while you still have a working key. All-keys-lost programming takes more time and costs more than simply cutting a spare — a small step now that saves a lot later.

Mercedes-Benz key replacement cost

Cost depends on the exact key technology your 2023 Mercedes-Benz S-Class uses — a basic transponder key is very different from a proximity smart fob — plus whether it is a spare or an all-keys-lost job. Call (408) 755-3415 with your year and model for an accurate quote.

That is why we quote based on your specific make, model, and year rather than a generic number. Call (408) 755-3415 with those details and whether you still have a working key, and we will give you a clear, honest price.

An all-keys-lost situation typically costs more than cutting a spare, simply because it requires additional programming. It is one more reason a spare key made today is such a smart, money-saving move.
