my mortise lock fell inside the door. How do I know which mortise lock matches my door?

Well, there's no way to be 100% sure, but I think you might have had our 82-218. This mortise lock is known for accidentally falling into the door if the lock tongue isn't held firmly during replacement. I recommend carefully going over our measurements, then measuring the space left in your door to make sure this will fit. Also be sure to watch the video below.
