The solutions for a car key not responding to locking are: 1. Replace the key battery; 2. Use the mechanical key. The steps to replace the car key battery are: 1. Remove the mechanical key; 2.

I know this situation all too well when the car key doesn't respond after pressing the lock button! The most common reason is usually a depleted key battery—this little thing needs replacement every two or three years. Sometimes, it's due to signal interference, like when there's strong electromagnetic equipment near the parking lot, blocking the key's signal. Other times, it could be poor button contact or internal component damage in the key. Simple troubleshooting steps: first, try replacing it with a new coin battery, or press the button within half a meter of the car door to see if the indicator light turns on. If that doesn't work, try manually locking the car by inserting the key into the door lock. Don’t take it lightly, as this could leave your car vulnerable to theft. Get into the habit of keeping a spare key or regularly checking the battery to prevent many headaches. If all else fails, have a professional technician inspect the key module or the vehicle's receiver.
