How do i remove the glove box lock cylinder from the latch assembly for

SOURCE: Mitsubishi Galant 2000 Glove Box Lock

First off you will need your key to the lock and a 1/8" flat blade screw driver.  Notice that your lock only turns 1/4 rotation, after doing this procedure you will be able to turn the lock an extra 1/4 turn counter clock-wise (when viewed from the front of the latch).

Turn the lock so it is vertical (perpendicular to the latch itself (counter clock-wise)).  Turn the latch around so you can view the back and the lock is to your left.  Above the lock there is a slot that you can put your screw driver into (not the indention in the metal).  You need to insert your screw driver and listen very closely, you should hear your screw driver hitting the metal latch.  Once you push the latch down with your screw driver, turn the lock another 1/4 turn with your key from the front (counter clock-wise looking from the front).

Once the lock has been turn a full 1/2 turn, you should be able to push the lock out from the back of the latch.

To put the lock in the new latch, you have to have your key in the lock.  Put the lock in the latch with the one pesky keep latch facing the handle used to open the glove compartment.  Once the lock is in the new latch, turn clock-wise until you can't anymore (1/2 turn).

You're done my friend!
