Most Ottawa homes use a handful of lock types: knob and lever locks for everyday latching, deadbolts for real security, handlesets and mortise locks on some entry doors, plus specialty locks for sliding doors, windows and garages. Each does a different job, and knowing which is which makes it much easier to spot weak points and choose upgrades. Here is a plain-language tour of the main types.

Have a lock you cannot identify? Call (613) 707-4884 and describe it.

Latching Locks: Knobs and Levers

Knob and lever locks hold the door closed with a spring latch, the angled bolt that clicks into the frame when the door shuts. Many have a key cylinder or push-button lock built in.

  • Strengths: convenient, inexpensive and they lock automatically when the door closes.
  • Weaknesses: the spring latch is short and can often be forced or slipped, and the knob itself can be broken off. On an exterior door they should always be paired with a deadbolt.
  • Levers vs knobs: levers are easier to use with full hands, gloves or limited grip strength, which makes them popular in Ottawa winters and for aging in place.

Interior versions include passage sets (no lock), privacy sets for bathrooms and bedrooms (thumb-turn or push-button with an emergency release outside), and keyed entry sets.

Deadbolts

A deadbolt uses a solid bolt that is moved only by a key or thumb-turn, so it cannot be pushed back by sliding something against it. It is the core security lock on most Canadian exterior doors.

  • Single-cylinder: key outside, thumb-turn inside.
  • Double-cylinder: key on both sides; slower to exit in an emergency.
  • Keyless and smart deadbolts: keypad, app or fob operation, often with a backup key.

Handlesets and Entry Sets

A handleset combines an exterior thumb-latch grip with a deadbolt above it, usually on the front door. They look substantial, but their security still comes from the deadbolt portion, so the same advice about bolt length and strike reinforcement applies.

Mortise Locks

A mortise lock sits inside a deep rectangular pocket cut into the edge of the door, with the latch and deadbolt combined in one heavy case. They are common in older Ottawa homes with solid wood doors and in commercial buildings. Well-made mortise locks are very durable, but replacement parts and cylinders must match the existing case, so repairs are more specialised than with a standard bored lock.

Multipoint Locks

Many modern fibreglass and steel entry doors, and some patio doors, use a multipoint lock: lifting the handle drives bolts or hooks into the frame at the top, middle and bottom. They resist forced entry and help the door seal tightly against drafts, but the mechanism is built into the door, so repairs usually require the correct replacement gearbox.

Rim Locks and Night Latches

A rim lock mounts on the inside surface of the door rather than inside it. You will see them on older houses, apartment doors and as secondary locks. Some are vertical deadbolts that interlock with the strike, which can be quite strong when properly fastened.

Specialty Locks Around the Home

  • Sliding patio door locks: usually a hook latch; often supplemented with a bar or auxiliary lock. See sliding door lock repair.
  • Window locks: sash locks, casement locks and keyed or limiting devices.
  • Garage door locks: T-handle locks, slide bolts and locks on the door from the garage into the house.
  • Padlocks and cam locks: for sheds, gates, mailboxes and cabinets.

What Is Inside the Cylinder

Most residential locks use a pin-tumbler cylinder. Others use wafers (common on cheaper locks and furniture), discs, or high-security designs with sidebars and restricted keys. The cylinder type affects how easily the lock can be rekeyed, how resistant it is to picking and bumping, and whether keys can be copied freely. If you are concerned about manipulation, see bump-proof and pick-resistant locks.

Choosing the Right Mix

For a typical Ottawa house, a sensible baseline is a quality deadbolt with a reinforced strike on every exterior door, a lever or knob for latching, proper locks on sliding doors and ground-floor windows, and a secured door between the garage and the house.
