What Causes the Lights to Flash and Sound to Beep When Remotely Locking the Car but the Locks Don't Engage?
1 Answers
When remotely locking the car, the lights flash and the sound beeps but the locks don't engage. This situation can be caused by the following main reasons: Insufficient battery power in the remote key can cause the key light to flash but the doors won't lock. Low battery power and voltage can lead to unstable circuit performance, resulting in reduced wireless communication range. In this case, you can try locking the car by getting closer to the vehicle. If necessary, simply replace the battery. Remote keys use two types of radio frequency forms: short-range infrared remote sensing and short-range wireless radio frequency. Regardless of which form is used, both the transmitting and receiving circuits are prone to malfunctions. This is determined by three factors: circuit design, component quality, and usage conditions. If a malfunction occurs, the remote key hardware needs to be replaced. Both short-range infrared remote sensing and short-range wireless radio frequency are highly sensitive to high-power radiation interference. When using the remote key, it's best to stay away from high-power devices and other communication equipment to prevent strong magnetic fields from affecting communication. For this issue, you can observe the surrounding environment and press the button again.
