Why is the car key light flashing?

Possible causes include a faulty contact switch inside the key head or a dead battery. It is recommended to visit a repair shop for diagnosis to determine the specific reason. Additional extended information is as follows: 1. Car smart keyless entry system: It adopts the world's most advanced RFID radio frequency technology and the most advanced vehicle identity coding recognition system. It is the first to apply a miniaturized, low-power RF antenna development solution, successfully integrating remote control systems and keyless systems while maintaining traditional vehicle circuit protection, truly achieving a dual RF system and dual anti-theft protection, providing maximum convenience and safety for car owners. 2. Car engine anti-theft light: If the car engine anti-theft light flashes at a frequency of once every 1 to 2 seconds, it is normal. This indicates that the vehicle's engine has entered the anti-theft state, and the engine anti-theft system is functioning properly. This is a normal phenomenon and does not need to be deactivated. Moreover, the power consumption of the anti-theft light is negligible for the car battery, so there is no need to worry about excessive power consumption.
