Currently, the FBS4 system is extremely encrypted, and in many regions, only licensed car dealerships can purchase and program these secrets.Keyless-Go Functionality: Keys equipped with "Keyless-Go" (permitting the motorist to start the car with a button while the key remains in their pocket) are considerably more pricey than basic SmartKeys.Emergency Blade Cutting: The electronic "fob" is only half the story. Every Mercedes key includes a concealed mechanical emergency blade. Having this blade laser-cut to match your door locks adds to the labor cost.Service charge: If a chauffeur has actually lost all keys, the price skyhoots.

Always inspect the battery before presuming the transponder is dead.FREQUENTLY ASKED QUESTION: Frequently Asked QuestionsCan I program a Mercedes key myself?
No. Mercedes-Benz secrets need customized diagnostic software application and an interface with the car's OBD-II port or ignition module. There is no manual "button-press" sequence to configure these keys.
For how long does it take to get a replacement key?

You ought to take the vehicle to a dealer or a certified locksmith immediately to have actually the taken key "de-authorized." This guarantees that even if the thief has the physical key, they can no longer start the engine.
Does the key cost differ by design (e.g., C-Class vs. S-Class)?
Usually, the innovation inside the key determines the cost more than the model of the car. However, S-Class and G-Wagon keys might in some cases bring a premium rate due to more sophisticated "Keyless-Go" features or premium surfaces.
Is the battery covered under warranty?
Normally, no. Key fob batteries are considered "consumable" products, similar to wipers or tires. However, if the key fob itself stops working due to a production problem within the bumper-to-bumper guarantee duration, it may be covered.

The high cost of a Mercedes-Benz extra key is the price of security. While spending ₤ 500 or more on a little piece of plastic and metal is frustrating, it reflects the sophisticated innovation securing the automobile from theft.
