Lock Replacement in Saint Paul, MN

When replacing beats repairing

A latch that no longer catches, a cracked case or a knob set with no parts left has worn out. Replacement swaps the lock itself, where rekeying only changes which key works. The choice comes up often in Saint Paul, where buildings from 1939 or earlier hold 42.0 percent of homes, against 15.3 percent for Minnesota and 11.5 percent for the nation (Census Bureau, 2024).

Doors on West 7th Street and the Hill

• West 7th Street grew west from Irvine Park. The 2011 Saint Paul historic context study lists it among the largest concentrations of pre-1865 houses, in wood frame, brick or limestone.
• The Hill District, meaning Ramsey Hill, Crocus Hill and the Summit Avenue area, replaced Irvine Park as the city's finest address in the 1890s.

Doors that old may be original, and they may not be drilled for the standard deadbolt size that most newer locks are made to fit. If the mortise case inside is sound, ask about repair or rekeying first. If not, the new lock has to suit the door.

The deadbolt definition for dwelling units

Saint Paul Legislative Code Section 34.09(3)(i) calls for a dead bolt lock, as defined in Section 34.07, on each entry door to a dwelling unit or to a rooming unit that is not a guest room. The bolt must be worked from inside by a handle, knob or similar device, lock from outside and project at least one inch. The metal strike must be at least .062 inch thick, held by at least two No. 8 screws or equivalent. The city handout behind this was last revised in 2015, so in a rental, ask that a replacement unit deadbolt meet the definition and confirm the current code with the city. This is general information, not legal advice.

What to send

• photos of the lock from both sides and of the door edge
• the door's thickness, if you can measure it
• whether it is a house door, a unit door or a shared entry
• whether the new lock should match your other keys
