How to Program a MERCEDES Truck Key
Our parts department is happy to help you, whether you need to replace a battery or if your key no longer works. Please keep in mind that replacement keys should be ordered and synchronized in the dealership in person. This is done to ensure the safety of your vehicle and security. Only you or a person authorized by you may request this service.
Keys
There have been some claims that you can reprogram a Mercedes key, however this isn't true. Once paired, the key will not work with any other car. The beam of metal on the key has a distinct profile that the Mercedes system detects and only recognizes. The blank MERCEDES truck keys are a different shape, and will not work in the system.
The dealership will have to purchase a new, compatible key for your vehicle from Mercedes; they don't keep them on hand at the parts department. When picking up your key, you will need the original title, registration, and the driver's license, passport or identification card. This helps to verify that you are the owner of the vehicle and not someone who is trying to steal it.
If you have an authorized representative or delegate who picks keys on your behalf They must provide all of the above documents along with the signed and dated proof of authorization from the owner. The authorized representative or delegate must also bring the vehicle into the dealership in order to retrieve the keys. Contact the dealer if have any concerns. They are happy to assist. They will tell you whether they already have the key or if Mercedes requires a new key that is compatible.
Remotes
In some MERCEDES vehicles the remote key comes with touchscreens that display virtual buttons. When a button is touched, it sends infrared signals to control devices. The screen can be programmed using a graphical interface program on the computer of the user. The "buttons" on the screen are actually images that represent components of electronic circuits. They comprise resistors (resistors) and capacitors (inductors) as well as potentiometers (potentiometers), transistors (diodes), integrated circuits & switches, and diodes.
It may be difficult to unlock the truck if you've locked your keys in the boot. This is because the lock door and cylinder of the Mercedes-Benz could be damaged. You could try using a rope that has an a slip knot to secure the lock cylinder and pull it open however, this isn't a sure-fire method. It is possible to contact an emergency roadside assistance or a locksmith to open the truck.
The lower level case has a panel that is opened to store the batteries. The panel is a light-brown color, with white writing to indicate the type of batteries that are recommended (UM-4/AAA). The panel also has an Plus and Minus sign indentation that indicates the direction to install the coils of battery.
truck key programming come with Keyless Go unlock or start your car even if you don't have the key. This is accomplished by through a process called passive entry and go. This is accomplished through a transponder built into each SmartKey, which allows the vehicle to recognize the driver if it detects the key within close range.
The key transmits signals at a low frequency that are picked up from both the outside and inside the door handles. If the transmission matches the ID number on the PASE module (Passive Access and Security electronics) the system will allow the key to function as a passkey that allows you to operate the vehicle.
These systems are intended for "replay attacks," where a hacker could record and replay control signals in order to gain access to an vehicle or building. To avoid this the risk, a specific algorithm makes sure that every transmission sent by the key fob differs from previous ones. This means that if a burglar records one of these transmissions, and then attempts to use it again, the car's PASE module will detect the attempt and deny access.
