Locksmith in OakvilleSmart locks,
fitted to a sound door

It is the natural moment, because the door is already open for repair. A deadbolt with a full one-inch throw, a hardened insert against sawing and a low-profile face that resists a wrench grip, graded to a recognised durability standard, takes little extra effort to fit now compared with a return visit. Pair it with the reinforced strike and long screws and the door becomes hard to attack from any side. The choice is yours; the locksmith shows the options and lets you decide.

Most residential doors have the standard preparation these locks are designed around: a large hole for the lock body, a smaller one in the edge for the bolt, and a thickness between roughly 35 and 45 millimetres. The locksmith measures all three plus the backset before recommending a model. Thicker doors take an extension kit, thin or glass-panelled doors and older doors with a mortise pocket call for a particular model or some preparation, and all of that is sorted out before the box is opened.

The broken piece is removed first, using extraction tools that grip and draw it out rather than push it further in, and then the lock is opened the usual way. A key rarely snaps in a lock that is otherwise healthy, so the old cylinder is checked afterward, and if wear caused the break, replacement rather than a repeated repair is the sensible next step.

Often, yes, particularly for a mechanical lock, where a worn wheel pack, drive cam or spindle can be replaced individually within the existing lock body. An electronic lock's circuit board and keypad are less often repairable in place and are more commonly swapped for a comparable or higher-rated replacement unit that fits the same cutout.
