critical Sargent mortise lock fail

When they won't open from inside or outside all of sudden it's almost always not a good thing :( This lock is also about 15 years old so...it's time to call it. Luckily we can replace just the lock body, but this one also gets a new thumbturn due to tailpiece twisting (common replacement) Pretty lucky on the opening, a tighter fitting door would have been a vastly different and way more dramatic & messy opening. 👍🏼✌🏼
