Doors and Windows - Spring Door Hinge

I am having a problem with the door going from my house to the garage. The locking mechanism is stuck and broken and the door won't open. So I want to remove the hinges while it is closed in order to get the door open and be able to work on the door handle. How do I remove the spring hinges? They aren't like typical hinges where you just push the pin up and out.

Wrong approach. Using a hacksaw or saw zaw cut the lock knob or lever off. Then drive out the other side with a hammer & drift and use a screwdriver or similar tool to operate the latchbolt.

Attempting removal of spring hinges in the closed position is foolish. It's a good way to hurt yourself or someone else. They are installed or removed in the open position with spring tension at a low level and the adjusting nut or screw locked in position.

Disassemble the handleset to see if you can manually retract the latch.

Release the tension on the hinge first, probably by using a screw driver and allen wrench. Then unscrew the handleset as grob62 suggests. You will destroy alot less than with a hacksaw and hammer.
