Check for a reinforcement metal strip.

If your latch does not have a metal strip at the back, then you may skip this and proceed to the following step.

If your latch does have the metal reinforcement strip, use pliers to tilt the strip to allow the metal bar to slide out. Apply minimal force to avoid breaking/tearing the metal strip.

Tearing the reinforcement strip might hinder your entire replacement and could lead you to replace the latch with a newly bought one.
