Car door locks cannot be opened from the outside. The solutions are: 1. Check if the vehicle's battery has power; 2. Inspect the car key for damage; 3. Replace the door lock block cable; 4. Use a spare key to unlock; 5. Contact a locksmith company to unlock; 6. Check if the child safety lock is engaged. The reasons why car door locks cannot be opened are: 1. The central locking system is activated; 2. The door lock block cable is malfunctioning; 3. The key button is unresponsive; 4. The car's battery is too low; 5. There is a strong signal interference source in the surrounding environment; 6. The anti-theft system is faulty; 7. The remote control needs to be re-matched and encrypted.
I once encountered a situation where the car door lock wouldn't open. It happened in a parking lot when I was in a hurry to leave, and the key wouldn't turn when inserted. I first tried the spare key, but it still didn't work, so I guessed the lock cylinder might be stuck or there was some foreign object inside. Then, I opened the door from inside the car to check and found that the child lock wasn't engaged, but the door lock linkage was a bit loose. I used some lubricant spray I had at home on the keyhole and moving parts, gently tapped the door frame a few times, and finally managed to open it. In winter, cold contraction might also cause the lock to stiffen, and spraying some WD-40 or a similar product can temporarily solve the issue. However, the root cause might be wear on the linkage or door deformation, so it's better to have it adjusted at a professional auto repair shop to avoid more expensive repairs later. I usually make sure to clean the locks regularly to prevent dust and dirt buildup, which works quite well.
