Will a Mercedes car key break if dropped?
1 Answers
Mercedes car keys will not break if dropped. Key condition: If a remote car key falls to the ground and does not break apart, it is generally fine. If it shatters upon impact, the chip inside may be damaged. Key battery: Generally, car keys use button batteries, which have a relatively long lifespan. Typically, such a battery can last for more than 3 years. Considering spare keys, many car owners may not even use up the battery before changing cars. Basic components: The system mainly consists of two parts: the transmitter and the receiver. Transmitter: Composed of a transmission switch, transmission antenna (keypad), integrated circuit, etc. It contains an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency is selected according to the radio standards of the country of use, and the transmission switch sends a signal each time it is pressed. Receiver: After the transmitter sends the identification code via shortwave modulation, it is received by the car's shortwave antenna and processed by the distributor into the receiver's electronic control unit for demodulation. The demodulated identification code is then compared; if it is the correct code, it is input into the control circuit to activate the actuator.
