What to Do When the Car Key Won't Open the Car?
1 Answers
You can use the spare mechanical key to open the car door and check whether the indicator light on the remote flashes when unlocking. If it does not flash, the issue lies with the remote key itself. If it flashes but the vehicle's central control does not respond, troubleshoot the unlocking circuit of the central lock. More detailed information is as follows: 1. If the remote key's indicator light does not illuminate, it may be due to a depleted battery in the remote key or strong signal interference in the surrounding area. If the remote key is out of power, it cannot transmit signals, and the receiving module cannot detect any signals. As a result, the remote fails to function, preventing the car door from opening. Replacing the remote key's battery can resolve this issue. Generally, a mechanical key is hidden inside the remote key, and using this mechanical key can also open the car door. 2. If even the mechanical key cannot open the car door, the car's central lock system may be in an electronically locked state. Wait for one or two hours until the lock is released, then attempt to unlock again. Another possibility is that the car door lock cylinder is stuck due to prolonged disuse and cannot be turned. In such cases, if you want to solve the problem yourself, the only option is to resort to forceful measures, such as breaking the car window.
