How do i remove a commerical lockset?
For Schlage, Corbin-Russwin, Falcon brands, you remove the inside knob by sticking a long metal pin or a straightened out large paperclip into the hole in the knob towards the edge of the door and press in the springy retainer. In some brands, you have to back off the rose to get to the retainer. While pressing in the retainer, pull the knob away from the door. If the pin is all the way in, the knob won't move away more than about 3/32", so after it starts moving, remove the pin and the knob should come off the rest of the way. If the inside knob has a keyhole, then you need to turn the key about 90 degrees or as far as it will go, before the retainer will move. If you don't have a key, then pick it, or drill the pins so it will turn. If you don't care what happens to the old lock because you are going to replace it, you can cut off the inner knob with a hacksaw. Cut as close to the rose as possible. Once you have the knob off, use a spanner tool to remove the inside rose trim without scratching it, and then pull the lock out of the door from the outside. If you don't care about the lock, you can use a pipe wrench or pliers to remove the rose. On non-commercial locks, you remove a decorative cover over the inside rose trim, and then have to remove a couple of screws to get the inside trim off the door, then you can remove the lock from the outside of the door.
