What Causes the Car Key to Not Respond and Unable to Open the Door?
1 Answers
The remote key cannot open the car door, which could be due to the remote key's battery being dead, the car's battery being dead, or strong signal interference in the surrounding area. If the mechanical key also fails to open the door, it might be because the car's central locking system is in an electronically locked state or the door lock cylinder is stuck. If the remote key cannot open the door: Replace the remote key's battery or find the hidden mechanical key inside the remote key to open the door. However, manufacturers now often hide the keyhole for aesthetic reasons. If the mechanical key cannot open the door: There are two possible scenarios. One is that the car's central locking system is in an electronically locked state, requiring a wait of one to two hours for the lock to release before attempting to unlock again. The other is that the door lock cylinder has become stuck over time and cannot be turned. In this case, you can only contact a 4S store for repairs or resort to forceful methods like breaking the window. Functions of the car remote key: Press and hold the lock button after turning off the engine to close the windows; press the horn button on the key to alert the owner of the vehicle's location; press and hold the trunk unlock button to open it automatically; press the unlock button once to open only the driver's door, and press twice to open all doors. Car key maintenance tips: Avoid frequently placing the key with metal objects; do not store the spare key in the car door; prevent the smart key from falling or being impacted; avoid exposing the smart key to high temperatures or liquids; do not place the key near electronic devices. Door precautions: Try to avoid exposing the car door lock to rain, as the small springs inside the lock can rust, leading to reduced flexibility. When using the door lock, if you notice difficulty in operation, spray lubricant on the lock tongue. In extremely cold weather, the door might freeze shut. Use warm water to thaw it or wait for the temperature to rise before attempting to open it.
