What to Do When the Car Key Won't Open the Car?

[DiJourney]

Solutions are as follows: 1. Use the spare mechanical key to open the car door and check whether the indicator light on the remote control flashes when unlocking. If it doesn't flash, the problem lies with the remote key itself. If it flashes but the vehicle's central control doesn't respond, troubleshoot the unlocking circuit of the central control lock accordingly. 2. If the remote key's indicator light doesn't turn on, it may be due to a drained battery in the remote key or strong signal interference nearby. A dead remote key battery prevents the remote from transmitting signals, and the receiving module cannot detect any signals. Therefore, the remote fails to function, making it impossible to open the car door. Replacing the remote key's battery can resolve this issue. Generally, a mechanical key is hidden inside the remote key, and using the mechanical key can also open the car door. 3. If even the mechanical key can't open the car door, it might be because the car's central lock system is in an electronic lock state. Wait for one or two hours until the lock is released, then try unlocking again.
