Our parts department is ready to assist you, no matter if you require replacement of the battery or if your key no longer works. Please keep in mind that replacement keys must be purchased and synchronized at the dealership in person. This is done to ensure your car's safety and security. Only you or a person authorized by you may request this service.

Keys

There are some reports that you can reprogram a Mercedes key, however this isn't the case. Once paired, the key cannot be used with any other vehicle. The key has a particular profile in its metal beam, and the Mercedes system scans for this and only recognizes that particular key. The keys for the truck that are blank are a different shape, and therefore will not function in the system.

The dealer must order from Mercedes a new key that is compatible with your vehicle. They do not have keys in stock at the parts department. You'll need the original title or registration and a driver's license, identity card, or passport to show when you pick up the key. This helps confirm that the person who has the key is the owner and not trying to steal the vehicle.

If you have an authorized representative or delegate to pick keys on your behalf they must supply all of the above documents as well as a signed and dated letter of authorisation from the owner. The authorized representative or delegate must also bring the vehicle to the dealership in order to retrieve the keys. Contact the dealer if have any concerns. They will be happy to help. They will inform you whether they have the key or whether Mercedes needs to order a new key that is compatible.

Remotes

In certain MERCEDES vehicles the remote key comes with a touch screen that shows virtual buttons. When the remote key is pressed the infrared signals are transmitted to devices that control them. A graphical interface software program can be used to program the screen. The "buttons" on the screen are actually images that represent the components of an electronic circuit. They include resistors (resistors) and capacitors (inductors), potentiometers (potentiometers), transistors (diodes) integrated circuits and switches, and diodes.

spare truck key may be difficult to open the door of your truck if you have locked your keys inside the boot. This is because the lock door and cylinder of the Mercedes-Benz may be damaged. It is possible to use a rope that has a slip-knot to hook the lock and pull it out, but this method is not completely safe. You may need to call an emergency roadside assistance or a locksmith to open the truck.

The lower level case features a panel which can be opened in order to store the batteries. The panel is a light brown color with white writing that indicates the type of batteries that are required (UM-4/AAA). The panel also has a Minus and Plus sign indentation that indicates the direction to install the coils of battery.

Keyless Entry System

Using a technology called passive entry and go, SmartKeys with Keyless Go can unlock or start your vehicle even if the key is not inside. The SmartKeys come with a transponder that allows the computer of the vehicle to recognize a driver by sensing the key's proximity.

The key transmits signals at a low frequency that are received both inside and outside of the door handles. If the transmission matches the ID on the PASE module (Passive Access & Security Electronics) it is authorized by the system that the key act as a passkey that allows you to operate the vehicle.

These systems are designed to prevent "replay attacks" which could allow a hacker to record and replay control signals and use them to gain access to a car or building. To stop this from happening the system uses a special algorithm that ensures that every signal transmitted by the keyfob is different from previous ones. The PASE module in the car will be able to detect any attempt by a criminal to record one of these transmissions, and then tries to reuse it.
