2011 Mercedes-Benz S-Class Remote Head Key Replacement - Fast, Affordable & Professional

No key? No problem. All-keys-lost is actually one of the most common jobs we do. For your 2011 Mercedes-Benz S-Class, here is exactly how we handle it.

First, we come to wherever the car is. You do not need to move it. We cut a brand new Remote Head Key from scratch using professional equipment. The key is cut to the exact factory spec so it matches your ignition, doors, and trunk.

Next, we plug into the OBD port and run the all-keys-lost procedure. This clears the old key data from the immobilizer and registers the new one. After programming, we handle the remote setup and test everything. The car starts, the remote locks and unlocks, and we make sure the immobilizer is not throwing any codes. You pay the quoted price and drive away.

The dealer would charge $$395+ and make you wait days. We charge around $$185 and do it right now. We have handled over 10,000 keys in Fallbrook over 8 years.

Save vs the Dealer on Your Mercedes-Benz S-Class Key

Get your key for hundreds less than the dealer. Same quality, same result, better price.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

“Very professional and extremely affordable. The price was literally about three times cheaper than what my dealership quoted me. Fast service and no stress at all. Highly recommend.”

Mercedes-Benz S-Class Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my Mercedes-Benz?
Call a mobile locksmith, not the dealer. Mercedes dealer AKL quotes run $1,000 to $2,000 before you add towing, and the key may take weeks to arrive from Germany. One owner was stuck for almost two months. We come to your location in Fallbrook, read the EIS, cut the key, program the transponder and remote functions, and test everything before we leave. On FBS3 platforms like the W204, W211, and W221, we handle everything on site in a single visit. No tow, no weeks of waiting, no dealer markup.
Can you delete lost or stolen keys from my Mercedes-Benz so they no longer work?
