Lookign at a Weslock deadbolt yesterday. Open the door, turn the knbo. Didn't turn.
Take the back off. Fgirue it's probably tailpiece mistimed.
Tail is twisted about 40 degrees.
Start to straighten the tail. Put it back together.
The little hole where the tail goes is split.
Bolt only goes about 1/4 inch cause the diecast hole is split.
Further investigation. Door swings ab it low (new home) and bolt hits the bottom of the strike.
If the door isn't locking, then REALLY crank on the handle, right?
