Keys

Some people have claimed that you can reprogram your Mercedes key. It's not the case. The key is programmed "for for the rest of time" and once it's programmed to a car it will never work with another. The key has a distinct design in its metal beam and the Mercedes system looks for this and only recognizes the specific key. A new blank key for the Mercedes truck is of a different form and won't work with the system.

The dealership must order a compatible, fresh key for your vehicle from Mercedes They don't have keys in stock at the parts department. When you are picking your key, you will need the original title, registration, as well as a driver’s license, passport or identification card. This helps confirm that the person is the owner and not trying to steal the vehicle.

If you have an authorized representative or delegate to pick up the keys on your behalf they must provide all of the above documentation along with the signed and dated proof of authorization from the owner. The authorized representative or delegate must also bring the vehicle to the dealership to retrieve the keys. If you have other questions, call the dealer and they will be more than happy to assist. They will let you know whether they already have the key or if Mercedes needs to order a new key that is compatible.

Remotes

In certain MERCEDES models the remote key comes with touchscreen that shows virtual buttons. When a button on the remote key is pressed it sends infrared signals to devices that control them. A graphic interface program can be used to program the screen. The "buttons" on the screen are actual images that represent parts of an electronic circuit. These include capacitors, resistors, inductors, potentiometers, transistors, diodes integrated circuits, and switches.

If MAN truck key lock your keys in the boot, it can be difficult to get them out of the truck without damaging the door and the Mercedes-Benz lock cylinder. Try using a rope that has an a slip knot to secure the lock cylinder and then pull it open, but this isn't a foolproof method. It is possible to contact an emergency roadside assistance or a locksmith to unlock the truck.

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

Keyless Entry System

By using a technique known as passive entry and go, SmartKeys with Keyless Go can unlock or start your vehicle even when the key isn't inside. SmartKeys have an RFID chip that allows the computer of the vehicle to identify a driver when it detects the key's proximity.

The key transmits low-frequency signals which 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 authorizes the key to function as a passkey 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 prevent this, a special algorithm ensures that every transmission transmitted by the key fob is distinct from previous ones. This means that if a thief records one of these transmissions, and then attempts to duplicate it the car's PASE program will detect the attempt and deny access.
