The reason why the key cannot be pulled out of the 2013 Buick Excelle GT is that the button on the spring is stuck inside the spring, making it difficult for the spring to rebound. Even when shifted to the P gear, the computer cannot recognize it, so the key cannot be pulled out. The basic components of a remote key consist of the following 2 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 on the opposite side of the circuit. The transmission frequency uses radio waves, and the transmission switch button sends a signal once each time it is pressed; 2. Receiver: After the transmitter uses shortwave modulation to send the identification code, it is received by the car's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit through a distributor for demodulation, and then compared with the identification code of the demodulator.
