If the door on a Hyundai Gl will not open from the inside, the child safety lock mechanism should be checked. The lock mechanism is found inside the door jab underneath a label that says 'child lock'.
Go in from another door and open it from the inside.
A person a can open the rear door from the inside. Get into the car from another door that will open and open it from the there.
You have to pull the inside door panel off. Once removed, look for the door latch mechanism and pry it with a screwdriver. This will release the door.
disconnect the battery and try to open manually from inside
The lever came loose. It needs be re-attached. I have had to do that manually and it requires going into the door.
The linkage may have popped off or the lever on the inside handle may be broken. Remove the inside door panel and you will probably see what happened.
if its a lift up handle and wont open your door most probably the rods come out of its slot inside the door
I had to jam something on the release lever inside the door, and go around and manually pull the door open. The cause is that the spring had broken. The catch was being released, but nothing was pushing the door open. I have to buy a new spring and install it once it was open
the linkages to either the handles or the lock or both has come off. here's the kicker... you need to open the door to take of the inside door pannel to fix it. try to remove the pannel with the door closed. or a "skilled" vheicle locksmith could open it from the outside...but it's not cheap.
Take inner door panel off and look inside the door and you will probably find a rod off the outside door handle.
Use the key to open the door.
try hitting th inside door panel just above the door handle my 95 jammed up and that's what i did it knock something back into allignment i guess worked fine ever since
