Forum Title: How to remove a Master Lock Deadbolt
I've got a single cylinder Master Lock Deadbolt to remove..... We bought a house and the owners gave us a pile of keys... we have 7 external doors... by time we figured out where hey all went we were missing the deadbolt key for the main door. We thought this was no big deal and we would buy a replacement and switch it out. Well now we can't get the darn thing out. Its a single cylinder deadbolt. There were two screws on the inside nob and we removed those.... just like every online how to remove a deadbolt direction the inside and outside should pull apart... not so much. I've tried giving it a little help by prying at it thinking it may be stuck to the paint, that didn't help or be the problem. I don't see any pins holes or allen wrench openings. I'm at a loss for what else to try except drill or cut this thing out. Any help is greatly needed I'm going nuts!!!!

First off, where does the heater get it's air from? There should be a furnace filter located somewhere on the furnace. The intake air is filtered air. I just want you to make sure that you have ducted intake air coming from somewhere else (cold air returns) because occasionally furnaces will need to have makeup air coming from the doorway. Assuming your heater has ducted intake air and that it is okay to put a door on this opening, I would suggest that you yank the existing casing and jambs, and just buy yourself a prehung 36 door that comes with it's own jamb, door and hinges. Once you install it, you would put new casing on to trim it out. If you don't want a hinged door, you could install bifold doors. But you will probably still want a new door jamb that is 36 wide. You'd have some pretty big gaps around the bifolds since the opening is 36 1/2. A sliding door (pocket door) would involve a lot of demolition along with a new header and I doubt you're up for that. Furnaces almost always need some makeup air, so you may need to have it checked out by an HVAC technician who can tell you what it's needs are. Or if you have a manual, maybe you can look it up. Otherwise, let us know what model you have, and maybe someone here can figure out what it would need for fresh air ventilation.... you may need to cut a louver (or install a grille) onto the new door.

Yeah, I've never seen a lock held in by anything other than the two main screws. You can try unscrewing and loosening the bolt part, it's possible that excessive friction is holding it in. If all else fails, get a bigger hammer...

Ok thanks, doesn't sound like there is any trick to it. I got a tip from a guy at work to put the screw back in just enough to grab the lock and then hit the screw to push out the other side. I'll try this and the pliers on the nob, although I kinda already tried this I'll give it a little more effort. Thanks!
