Will Car Keys Be Damaged by High Temperatures?

[DeCollin]

Car keys can be damaged when exposed to high temperatures. The basic components of a remote key consist of the following two points: 1. Transmitter: Composed of a transmission switch, transmission antenna, 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 uses radio waves, and the transmission switch button sends a signal once per press; 2. Receiver: After the transmitter sends the identification code using short-wave modulation, it is received by the car's short-wave antenna and enters the short-wave high-frequency amplification processor of the receiver's electronic control unit through a distributor for demodulation, where it is compared with the demodulator's identification code.
