Older homes have character, and sometimes they have door hardware that hasn't been touched in decades.
Look at the deadbolt first
Some older doors have only a knob lock, or a deadbolt with a short throw. A proper deadbolt installation with a full one-inch throw is one of the best upgrades you can make.
Check the frame and strike
Decades of settling can pull a door out of line, so the bolt drags or doesn't reach the strike. Old strike plates are often held by short screws. Door lock repair can realign the latch and reinforce the strike.
Unusual sizes
Older doors may have nonstandard bore holes or backsets. Measure before buying new hardware, or have a locksmith handle the lock installation so the fit is right.
Unknown keys
In an older home, there's no telling how many keys have been handed out over the years. A rekey fixes that without replacing hardware you want to keep.
