Why Can't the Rear Car Door Open?
1 Answers
1. Remote Control Failure: Unresponsive buttons, low battery, environmental factors, strong signal interference or shielding, anti-theft system malfunction, or the need for remote control re-encryption can all lead to remote control failure. Trying a spare remote key can help diagnose the issue correctly. 2. Frozen Door in Winter: In northern regions, winter temperatures are extremely low, often below freezing. After washing the car, residual water can accumulate in door handles, locks, and door frame gaps. Overnight freezing turns this water into ice, firmly sealing the door shut by morning. In such cases, avoid forcefully pulling the door. The most effective solution is to pour warm water over the frozen areas to melt the ice quickly. Alternatively, waiting until midday when temperatures rise under the sun can also allow the door to open. 3. Door Lock Mechanism Malfunction: The likelihood of the door lock itself failing is quite low and mostly occurs in older vehicles. Regardless of the car's luxury level, while the working principle might be complex for the average person, the door lock structure is relatively simple, consisting mainly of a lock cylinder, lock block, central control motor, and operating mechanism. Most issues can be resolved by replacing the central control motor or lubricating the lock block and operating mechanism.
