In most cases, the rear door of the Kia K3 cannot be opened from the inside because the child lock is engaged. The child lock is located next to the rear door lock hole, and when activated, the door can only be opened from the outside. Common reasons why a car door cannot be opened are as follows: 1. If you are using a remote key, it is likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter is aging, causing the remote key to not work. In this case, you can use the spare mechanical key to open the door. 2. The central locking system is activated: When the door cannot be opened, you can first use the car key to unlock it, then lock it again, repeating this twice. Then locate the central locking button on the left front door trim panel in the main driver's compartment and press the unlock button. 3. The child lock is engaged: Most vehicle rear doors have a child lock, marked by a child symbol on the side of the door. If it is accidentally engaged and the door is closed, the door cannot be opened. 4. In the cold winter weather of northern regions, especially on rainy days, the door locks, handles, and door frames may freeze, making it impossible to open the door even with force, and potentially damaging the paint and seals. The solution is to pour warm water on the frozen parts to help melt the ice quickly.
I recently encountered a similar issue with my Kia K3. The rear door not opening from the inside is usually because the child safety lock is activated. That small switch is located on the edge of the door and can easily be bumped accidentally. Once turned off, the door should open easily. If it's not the child lock, it might be that the internal cable of the door handle is broken or stuck, especially in older cars where dust accumulation can block moving parts. I remember last time when I cleaned the door, spraying some lubricant improved the situation. Another common reason is damage to the door lock mechanism, such as a failed small spring inside, making the handle hard to pull. I suggest first checking the child lock position yourself. If that doesn't work, take it to a repair shop for inspection—don't force it open to avoid damaging the door. Timely action is crucial; a rear door that doesn't open affects passenger safety, especially in emergencies when it could be more dangerous.
