Why Can't the Door Open After Unlocking the Car?

Specific details are as follows: 1. Because the vehicle's computer has activated the corresponding safety feature, pressing the unlock button twice on the key will unlock the other doors. 2. Visit a 4S shop where they can connect to the computer and remove this restriction. Additional information: Failure of the keyless entry and locking function on the front passenger door handle: 1. It might be due to low battery power: Try using another battery. 2. A malfunction in the circuit board of the button can also cause the button to fail: It is recommended to visit a repair shop for maintenance and inspection. The keyless entry system utilizes the most advanced radio frequency identification technology, automatically opening and closing the door locks through the chip induction in the smart card carried by the car owner.
The car is unlocked but the door won't open—I've encountered this often, especially with older cars. The door lock mechanism might be stuck or rusted, particularly in humid rain or snow when the lock hole gets blocked, causing incomplete unlocking. Try unlocking repeatedly or use the key to open it mechanically for inspection. The child safety lock is another trap—if that small switch on the rear door isn't turned off, the inner handle won't open at all. I've accidentally triggered it several times. Additionally, a dented door or damaged lock cylinder can cause this. Last time I had my car repaired, a small pebble was stuck in the lock, causing a lot of trouble. If manual unlocking doesn't work, I recommend going to a professional shop to check the mechanical parts before it becomes a bigger issue. Don’t neglect lubricating the door locks during regular maintenance to prevent this.
