What is the reason that the car key does not respond when locking the car but responds when unlocking?

Possible causes include electromagnetic interference. It is recommended to move the car to a different location and test again. If the issue persists, you may need to visit a 4S store for re-matching. Precautions for using car keys are as follows: 1. Do not place the car key together with a mobile phone: Car keys use low-intensity radio waves, so they may not function properly under magnetic interference. Long-term proximity to a mobile phone can affect the smart key's performance due to the phone's frequency. Also, avoid contact with strong magnetic fields, such as high-voltage lines, transmission towers, or other areas with strong magnetic signals. Try to avoid parking the vehicle in such locations. 2. Do not drop the car key: Free-fall impacts are a nightmare for most precision electronic products, and smart keys are no exception. Therefore, handle them gently and avoid dropping or knocking them. 3. Avoid water exposure: If the key unfortunately gets wet, it is advisable to send it to a repair shop for inspection.
The other day, my car key suddenly malfunctioned. The unlock button worked perfectly with a single press, but the lock button wouldn't respond no matter how many times I pressed it. I was so anxious that I circled the parking lot several times. At first, I thought the key was broken, but after searching online, I learned it might be due to the key battery running low. The lock function requires stronger current than unlocking, so it stops working when the battery is weak. I hurried to the supermarket to buy a new battery and replaced it, and sure enough, everything returned to normal. Normally, if you're not careful, key button wear or oil stains can also cause this issue, especially since I often stuff my keys together with loose change, making them more prone to getting dirty. If a new battery doesn't solve the problem, you might need to check if the vehicle's receiver is faulty, such as due to aging wiring or a system crash. It's best to note the environment where the issue occurred—was it in a place with strong signal interference?
