How long does a Mercedes-Benz car key generally last?

[ElianaRose]

Generally, a Mercedes-Benz car key can last 2-3 years. Here is some knowledge about the usage of car remote keys: 1. When approaching the car: When the driver brings the key in their pocket close to the car, the key and the car begin to exchange preset command information via radio waves. Subsequently, the car's locking system, security system, and engine control system are all activated. 2. When opening the car door: As soon as the driver touches the door handle, the sensor detects this pressure, and the servo motor unlocks the door while the turn signal flashes twice. Then, the seat, steering wheel, and exterior rearview mirrors automatically adjust to the position suitable for the owner.
