What is the reason why the Zotye T600 cannot sense the key and fails to start?

Zotye T600 cannot sense the key and fails to start due to a dead key battery and radio interference. The basic components of the 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 each press of the transmission switch button sends a signal once; 2. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna and enters the receiver's electronic control unit through a distributor for demodulation by the shortwave high-frequency amplifier processor, where it is compared with the demodulator's identification code.
I also encountered a similar issue when driving my Zotye T600—the car key couldn't be detected, and there was no response when trying to start the engine. The main cause was insufficient battery power in the key fob, which was resolved by replacing it with a new battery. Additionally, faults in the key itself, such as internal circuit damage from being dropped or short-circuiting due to water exposure, can also weaken the signal. Problems with the vehicle's sensing system, like a loose or moisture-damaged antenna module—especially after rainy days—can lead to malfunctions. Signal interference from nearby wireless devices or placing the key near a phone can also block the signal. It's recommended to first try replacing the key battery; if that doesn't work, use the spare mechanical key to start the car or attempt a system reset: turn off the engine, remove the key, wait a few minutes, and try again. Always keep the key dry and avoid high-temperature environments. Don't worry too much—this is a common issue, and simple troubleshooting usually resolves it.
