A Key is the type of key your 1998 Mercedes-Benz C-Class uses. It contains an encrypted chip that communicates with your vehicle's EIS/EZS (Electronic Ignition Switch) module to authorize the engine to start. It also has 3 buttons for remote lock, unlock, and keyless go functions. Without proper programming, the key will be rejected by your Mercedes's immobilizer system. We program everything on site so your new key works exactly like the original.

“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”

“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”

Mercedes-Benz C-Class Mobile Service FAQ

Real costs, no dealer surprises

Do I have to go to the Mercedes-Benz dealer to get a replacement key?▼

No, not for most Mercedes models. A qualified mobile locksmith can cut and program a Key for your 1998 Mercedes-Benz C-Class right where the vehicle sits. Many Mercedes owners assume the dealer is the only option because that is what they are told. One owner said a Sprinter dealer flat-out refused to help with a replacement key and sent them to a third party quoting $1,200. Another had a "mobile Euro locksmith" make keys for their W212 E-Class on site. For older FBS3 platforms, a locksmith handles everything independently. For newer FBS4 cars, we will tell you upfront what is possible.
