BYD Surui cannot detect the key solution is: 1. The key battery is low and needs to be replaced; 2. The key itself has a problem and needs to be replaced with a new one; 3. There is signal interference near the parking spot, it is recommended to move the car to another location; 4. There is an issue with the fuse box, and the high-frequency receiver needs to be replaced. BYD Surui is a compact sedan with a body length of 4680mm, a width of 1765mm, and a height of 1490mm.

Not detecting the key is quite annoying, and I've encountered it several times. The most common reason is a dead key battery. Try replacing it with a CR2032 coin cell battery, which is cheap and easy to find at supermarkets. Sometimes environmental interference is the culprit, like having your phone, power bank, or metal keychain too close—move them away to an open area and try again. If the car battery is running low, it can also cause issues—start the car and check if the power is stable. If that doesn’t work, disconnect the car battery’s negative terminal for 10 minutes to reset the system—this trick works well for electronic locks. Lastly, if there’s still no response, it’s likely due to internal key damage or a vehicle sensor issue. Don’t force it—head to a 4S shop for professional repairs to avoid mishaps on the road. Safety first.
