In 1997 Mercedes began using an encrypted transponder key FOBs on all it's models.
The OEM Mercedes FOB contains a laser cut emergency key.
Mercedes-Benz was the first to introduce proximity keys (Keyless GO) system back in 1998. The system is either standard or optional equipment on different models. The keyless entry device contain a transponder chip that works with a battery.
Mercedes transponder keys mainly used as a vehicle anti-theft technology. Together with the immobilizer, transponders helps protecting your Mercedes from unauthorized access.
The immobilizer initialized to recognize each key by a programmable code. When a key with unmatched code turned in the ignition, the vehicle becomes immobilized. The fuel-pump will shut down and will not start for a few minutes.
Mercedes transponders uses the "Philips rolling code" system to change value each time the key is used. If an unauthorized personal will try copying the key data, it will be invalid the next time the key used.
Each immobilization system programmed with 10 unique chips upon manufacturing of the vehicle. 2-3 keys are provided when a new car is purchased, and each additional keys ordered through a dealer or a licensed locksmith. When reaching the 10 keys limit, the ECU replaced and align to accept 10 new keys. This process could cost $1k-$3k to do.
Mercedes offer no on-board interface to duplicate keys by yourself. Each key need to be programmed by the dealer or a licensed locksmith using dedicated programmers. Each additional key approved by Mercedes using the VIN before it can start the car.
Each new immobilized vehicle also provide a valet key. The valet key has a grey plastic head and doesn't allow access to the glove box or trunk. A valet key cannot be duplicated and designed to be used for emergencies.
Following are the list of Mercedes models that use transponders:
The procedure for getting a duplicate Mercedes key done by a local dealer or a car locksmith. You can duplicate the key by VIN or by a cloning process:
To duplicate a key the dealer will need the VIN and a proof of ownership which is registration or title and a match driver license. The vehicle does not need to be at the dealership.
Prices vary slightly from dealership to dealership, so you better call more than one dealer for the best price. Call the dealer and provide them your VIN to get a quote.
If you are not the owner of the Mercedes, you will need a signed power of attorney from the owner.
Mercedes key cloning is a job that very few locksmith can perform. The newer your Mercedes is, the harder it's going to be to find a locksmith who can clone your key.
A locksmith with Mercedes key programmer and diagnosis tool can create cloned key using 2 methods:
There is no onboard interface to program keys. Only the dealer or a locksmith can program keys and remote to all Mercedes immobilized models.
When you lose all your keys to a Mercedes the process is very similar to a key duplication. Reprogramming interface and tools are available only to the Mercedes dealer or to a licensed locksmith. The vehicle computer is reprogrammed to accept a new key from the list of 10 initial keys and reject the lost keys.
While some people complain about the limit of 10 keys for each ECU, the rolling code offer a great advantage. Since the 10 keys codes are already programmed, the dealer or a mobile locksmith don't need the car present to make a key.
Just like key duplication service, all they need to cut and program a new key is the VIN and a proof of ownership.
