How to Match the Chip Key and Remote Control for a 2007 Chery A5?
2 Answers
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.
As a long-time Chery owner, I have experience with the A5 key pairing. Let's start with the remote: gather all the keys you want to pair, sit in the car with the door closed, insert the original key into the ignition switch, quickly turn it on and off three times, and leave it in the off position. At this point, the anti-theft light will flash. Then quickly turn the key once more and immediately press any button on the first new remote. If you hear the door locks activate, it means the pairing was successful. Each remote must be paired within thirty seconds. The chip key is different—it must be matched at a professional auto repair shop using a diagnostic tool to pair with the anti-theft system. You can't do this yourself; you'll need to pay them to handle it. If you've lost a key before, it's recommended to replace all the locks and check the anti-theft module while you're at it. Otherwise, the old key can still open the door, but the remote function can be disabled separately. Be careful with your keys—parts for these older cars are hard to find nowadays.
