1. Check The Child Safety Lock
One of the most common reasons a car door won’t open from the inside is due to the child safety lock being engaged.
Some vehicles have a powered switch that accidentally engages from the inside, whereas other cars have a manual latch that needs to be toggled on the door itself.
This feature is designed to prevent children from accidentally opening the door while the car is in motion.
It’s very common to engage the child locks and not even be aware.
To check if this is the issue, locate the child safety lock button on the door panel usually right where the door latches, and make sure it’s in the correct position.
2. Inspect The Inside Handle

If the child safety lock isn’t the issue, the next step is to inspect the inside door handle.
Over time, the handle can become worn or damaged, making it difficult to open the door.
A lot of times simple plastic tabs break away and loosen mechanisms causing the handle to fail.
In some cases, it may simply be a matter of lubricating the handle mechanism to get it working properly again.
3. Check the Cable
The cable connecting the door handle to the latch mechanism can also be the culprit if a car door won’t open from the inside.
Cables can bend, stretch, and get tangled over time. They may even release from their mounting point.
Check the cable to make sure it isn’t frayed or broken.
If it is, it will need to be replaced.
4. Examine The Latch Mechanism

The latch mechanism is what holds the door closed and allows it to open.
If there is a problem with the latch mechanism, the door won’t open from the inside. It would also fail to close if you happen to get it open.
This could be a real safety hazard if left unsolved.
Check for any visible damage or wear and tear on the mechanism, and if necessary, have it repaired or replaced.
5. Test The Power Door Lock

In some cases, the issue may be with the power door lock system. If the door won’t open from the inside, try unlocking the door from the outside and see if that resolves the problem.
Use a keyfob if you have it to try unlocking the vehicle, if that doesn’t work try the power lock buttons inside.
If it does, the power door lock system may need to be repaired or replaced. This may be as simple as a fuse or as complex as a wiring short.
It’s best to start with the easy fixes and work your way up.
6. Consult a Professional

If none of the above solutions have worked, it’s time to consult a professional.
An experienced locksmith or auto mechanic will be able to diagnose the problem and provide a solution.
They will also be able to determine if any additional repairs or replacements are necessary to ensure the door opens smoothly and securely.
