The mortise lock is one of the most mechanically demanding lock types in residential and commercial use. Unlike a simple cylindrical lock that bores through the door face, a mortise lock requires a deep rectangular pocket cut into the door edge to house the full lock body. The mechanism integrates the latch, deadbolt, and sometimes additional features into a single unit. When a mortise lock fails — whether the cam breaks, the cylinder wears, or the case itself cracks — the repair requires careful disassembly, accurate replacement parts, and precise reinstallation to make sure the door operates smoothly. We carry common mortise lock bodies and cylinders and can source specific replacement hardware when the door's existing prep dictates a particular fit.
Multipoint locking systems take the complexity further. These are most common on European-style doors and higher-end entry doors, and they engage the frame at three or more points simultaneously when the handle is lifted and the key is turned. The mechanism runs inside a tall, narrow lock case mounted within the door stile. When a single point fails — a hook bolt, a roller bolt, a round bolt, or a swing hook — the entire door may be difficult or impossible to open or close properly. We work on these systems regularly and understand how each locking point type functions within the overall mechanism.
Beyond mortise and multipoint systems, we handle the full range of lock hardware found on local doors. That includes tongue locks, which use a spring-loaded angled latch as their primary holding point; roller pin locks, which are sometimes found on sliding or specialty doors and use a cylindrical pin rather than a traditional key-cut mechanism; round bolt locks, which throw a fully cylindrical deadbolt rather than the squared-off variety; and swing hook locks, which pivot a hook-shaped bolt around a fixed point to engage a strike — common on certain patio and French door applications. Each of these requires a specific understanding of how the bolt engages the frame and what failure looks like for that mechanism. We also work on standard door knob lock sets, lever handles, rim locks, padlocks, and cabinet locks across residential and commercial properties. On the automotive side, we handle car lockouts, transponder key cutting, and key fob issues — more on that in the FAQ section below.
