Plain talk about locks

Commercial doors work harder than residential ones: hundreds of cycles a day, a closer slamming the latch, deliveries propping the back door open in the cold. We specify hardware for that duty, keep closers adjusted so the door actually latches behind people, and make sure exit doors release with a single push and no key. Then we set a schedule so small wear never becomes a lockout.

Change or Rekey Locks

Older homes carry mortise locks with warded keys, brass knobs and strike plates fixed with tiny screws.

Small things.
Big difference.

The key you reach for. The door you come home to. Good locksmith work begins with understanding how you use them.

This group covers cylinders and deadbolts built to resist picking, bumping and drilling, strikes fastened into the framing, and patented key systems where every copy is authorised and recorded. We assess the whole door first, then recommend the level that fits.

    Lock Replacement & Upgrade

    The century home's original mortise lock takes a key the size of a spoon, sticks in humid weather and has worn its strike to a groove. You want a lock that works every day without giving up the old door.

Safes

Safe Opening & Combination Change

A safe opening and combination change service is built around confirming who has the right to be inside the safe before any tool touches it. Once that is settled, the locksmith identifies the safe's make, model and lock type, then works…

Which fix fits?

Tap a situation. The answer opens here.

If The padlock on the back gate has rusted shut.

Then Replace it with a weather-rated padlock.

A shrouded shackle and a drainage-friendly body cope with rain and salt far better than an indoor lock left outside.

If The shed holds the bikes and the lock is a flimsy one.

Then A hasp and a proper padlock.

The hasp matters as much as the lock; fitted with carriage bolts it resists prying.

If The mailbox key is lost and the mail is piling up.

Then Replace the mailbox lock and cut new keys.

With proof the box is yours, the cam lock swaps out cleanly and you get two keys for it. Mailbox Lock Replacement

2021 census: what it means at the door

Every square is one home in a hundred.

  • 52 in 100 homes · older homes
  • About 52% of homes in Cobourg were built in 1980 or earlier, according to the 2021 Census.Established homes often have non-standard bores and backsets from an earlier generation of hardware. A locksmith working in such an area carries adapter plates and cylinders in the older sizes, so an upgrade fits the existing door instead of forcing a new one.
  • Single-detached houses make up about 58% of homes in Cobourg (2021 Census).Neighbourhoods of houses beside townhouses and low-rise buildings have a range of door constructions: solid wood, steel, fibreglass and metal-clad. A locksmith who works in such an area is used to fitting hardware to all of them without new holes.

Short answers to common questions

Will the new cylinder fit my existing locks?

Usually. High security cylinders are made in the common formats: key-in-knob and lever, rim, mortise and interchangeable core, and many are designed to drop into popular residential and commercial locks. The locksmith identifies your format and confirms fit before ordering. Where a lock is an odd size or in poor shape, a matching lock body is fitted instead, and the door preparation is reused wherever it is standard.

What information helps before the visit?

A photo of each door's lock from inside and outside, the type of door, whether there is glass nearby and roughly how many keys are in circulation. For a business, a sketch of the doors and who needs to reach each area saves a great deal of time. Mention any door that sticks, has been forced or has a closer or push bar on it. With that, the locksmith arrives with the right formats and a plan to discuss.

Can a hardware store or kiosk copy my new key?

No. The blank for a patented keyway is distributed only through the manufacturer's network to locksmiths who hold the system, and the side milling or angled cuts need a machine set up for that line. A kiosk would have neither the blank nor the cut. Extra keys come through your locksmith, cut from code, once an authorised person has approved the order. That routine is a small inconvenience compared with never knowing who has a copy.

Can a high security cylinder be rekeyed later?

Yes. Like any pin tumbler it can be repinned to a new combination by a locksmith who holds the system, so a departed employee's key can be retired without replacing hardware. Some lines use interchangeable cores that swap in moments with a control key, which suits businesses with frequent turnover. Rekeying stays within your registered keyway, so the key control you paid for continues after the change.
