Keys

There have been some claims that you can reprogram a Mercedes key, however this is not true. The key is paired "for for the rest of time" and once it's programmed to a vehicle, it cannot be used with another. The beam of metal on the key has an exclusive shape, which is what the Mercedes system detects and only recognizes. The blank keys of the Mercedes truck are different in shape and therefore will not function in the system.

The dealer must purchase from Mercedes an additional key that is compatible with your vehicle. They do not have them in stock at the parts department. You will need to have the original registration or title and driver's license, identity card, or passport to show when you pick up the key. This will help verify that you are the owner of the vehicle and not someone who is trying to steal it.

If truck keys made have an authorized representative or delegate pick up the keys for you They must provide all of the above documentation along with an official and dated letter of authorisation from the owner. The authorized representative or delegate must also bring the vehicle into the dealership in order to get keys. Contact the dealer if you have any questions. They are happy to help. They will inform you if they have the key on hand or if they need to place an order with Mercedes for a fresh key that is compatible with your vehicle.

Remotes

In some MERCEDES vehicles the remote key comes with touchscreens that display virtual buttons. When the remote key is pressed, infrared signals are sent to control devices. The screen can be programmed by using a graphic interface program on the user's personal computer. The "buttons" on the screen are actually images that represent components of an electronic circuit. These include resistors (resistors) and capacitors (inductors), potentiometers (potentiometers) as well as transistors (diodes), integrated circuits and switches, and diodes.

If you lock your keys in the boot, it may be difficult to open the truck without damaging the door or the Mercedes-Benz lock cylinder. It is possible to use a rope that has a slip-knot to hook the lock and pull it out however, this isn't foolproof. You may need try it several times before calling a locksmith or roadside assistance service to help open the truck without damage.


The lower-level case has an opening panel that is able to be opened to store the batteries. The panel is a light brown color and has white writing to indicate the type of batteries that are recommended (UM-4/AAA). It also includes the Plus and Minus sign indents to indicate in which direction the battery spring coils should be positioned when installing the batteries.

Keyless Entry System

By using a technique known as passive entry and go, SmartKeys with Keyless Go can allow you to start or unlock your vehicle even if the key isn't in. The SmartKeys come with a transponder that enables the computer of the vehicle to identify a driver when it detects the key at close range.

The key transmits low-frequency signals that are detected both inside and outside of the door handles. If the transmission matches ID on the PASE module (Passive Access and Security Electronics) it is authorized by the system that the key function as a passkey for operating the vehicle.

These systems are designed for "replay attacks," where a hacker could record and replay control signals in order to gain access to an vehicle or building. To stop this from happening, a special algorithm ensures that every transmission transmitted by the key fob differs from previous ones. The PASE module inside the car will be able to detect any attempt by a criminal to record one of these transmissions, and then tries to reuse it.
