[MilesRose]

Here is the method to match the chip key and remote control for a 2007 Chery A5: 1. Insert the key into the ignition switch and turn it to the circuit-on position. 2. Press and hold the unlock button on the remote control for 5 seconds to match the chip key and remote control. Below is additional information about chip keys: 1. The chip keys used by car manufacturers are called magnetic chip systems. 2. The magnetic chip system does not require electrical power or its own energy source. It operates at a frequency of 125 kHz. Without external or internal energy support, its transmission range is limited to 1 to 15 meters. 3. When the key is inserted into the ignition lock and turned to the "on" or "run" position, the reading coil in the ignition lock cylinder reads the chip in the key. Each chip has a fixed digital code, and the coil compares the read digital information with the pre-stored information in the anti-theft system. If they match, the vehicle will start; otherwise, subsequent steps will not be executed.
