2 Answers
BYD Surui cannot recognize the key? Here are the solutions: 1. Replace the battery; 2. Get a new key; 3. Replace the high-frequency receiver. Reasons why BYD Surui cannot recognize the key: 1. Insufficient battery power in the key; 2. Malfunction of the key itself; 3. Signal interference near the parking area; 4. Failure of the vehicle's central control system. The BYD Surui is a compact car with the following dimensions: length 4680 mm, width 1765 mm, height 1490 mm, wheelbase 2660 mm, fuel tank capacity 50 liters. It is equipped with a 1.5L naturally aspirated engine, with a maximum power of 80 kW and a maximum power speed of 5800 rpm.
I encountered an issue with my BYD Surui not recognizing the key, which was quite frustrating. At that time, I simply replaced the key battery with a new one, model CR2032, which is commonly available in supermarkets or auto shops. If that doesn't work, try using the spare key to start the car—this can help confirm whether the issue lies with the key itself. Also, check if the key has been exposed to moisture or strong magnetic interference, such as from nearby microwaves or other electronic devices, as these can affect the signal. If the system still doesn't recognize the key, try restarting the vehicle or turning it off and on again to reset the computer's recognition. If all else fails, take the car to a BYD service center to inspect the receiver module—it might need reprogramming or repair. To prevent such issues, avoid exposing the key to strong impacts or keeping it in a pocket where it could get crushed, and regularly check the battery life as a precaution.
