Callin Residential Lock Latch Locks Up - Remove and Replace

Callin makes a beautiful lock. However, the latches are prone to jamming in such a way as to render your door inoperable. No matter what you do, whether you unlock it with the key or turn the inside and outside knob or lever, the door simply will not open. Here is what you can do:

1. Have a flat head screw driver, a hammer, and a pair of vice grips ready.
2. First, try to pry the door away from the jamb. Be careful not to go to far with this or you will mar your door and jamb, necessitating cosmetic repair. If this works, then remove the lock entirely and replace the latch with a new Kwikset latch from the hardware store.
3. If the door is too tight, remove the interior screws of the lock and remove the inside knob/lever. The outside knob will be locked into place because the latch is jammed. If you can remove the locking spindle (that is the tube-looking spindle that has a hole in the end which the interior knob turn-button inserts into) then you can remove the knob. I cannot in words describe how to do this. But there is a catch either at the 12 or 6 o' clock position underneath the spindle that is spring loaded. Turn the spindle half way between left and right with the tip of a 32 regular Phillips driver, lift up on the catch and hold it there, and slip the spindle out. If you are lost at this point, destroy the lock spindle where it joins the lock body. Just pry it apart. Just get the outside knob off!
4. Now you have to deal with a jammed latch. This may take some time. With your flat head driver, carefully destroy the latch so all the parts and guts come out. You may need a hammer to get started. Just use your flat head driver to pry the latch apart. Once all the parts are gone, you should be able to use a small driver to pry the latch back. The door should open. 
5. This may take you from 15 minutes to one hour or more. Replace the lock with another Callin, but buy an optional Kwikset latch.
