We have a Schlage door lock which we are trying to install. The inside latch on the knob will not turn to open or lock the door from the inside.

Try taking the knob out of the door and spraying the whole latching mechanism with WD40 or some kind of lubricant. There is a few moving parts in there that can get bound up. Hope this helps. Don't forget to leave feed back.

I agree with your Hacksaw method. Very easy and very fast. You are going to want to replace the knob anyway so this does not happen again. Just Hacksaw that knob as close to the door as you can without damaging the door. From there you are on your way to access to the parts of the lock. Now you can replace that knob and never have this trouble again!!!! One less headache in Life......Hope this helps you ........Joe

Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

SOURCE: Schlage deadbolt will not unlock even with the use of a key?

it sounds as though the linkage that pulls the deadbolt back has disengaged... if you undo the screws from the inside of the door and remove the manual knob there will be 2 more screws holding the key lock to the door. A thin flat bar is attached to the key lock that goes through the deadbolt and into the manual knob. This bar turns with the key, sliding the bolt on its track to lock and unlock the door. Once the lock is apart check the key in the lock to see if the bar turns when the key does. then see if there is anything that may be obstructing the deadbolt from sliding. The locks are pretty indestructible so if there is a problem it may have been from the install... perhaps the door is to wide for the lock to engage properly and the lock worked loose in the 6 months that it worked.
