Doors, keys and the people behind them

Moving house is a long list, and the locks are easy to forget until the first night. We suggest making them one of the first calls. A rekey of every exterior door, including the one from the garage into the kitchen, means the previous owner's spare under the mat and the copy their painter kept are just brass. You settle in knowing exactly how many keys exist.

The moving truck has left, half the boxes are inside, and the single key the previous owner handed over turns the knob but not the deadbolt. Someone locked it on the way out, and nobody has a key that fits it.

    High Security Locks

    You run a home office with client files and equipment, and your insurer has asked what kind of lock is on the door. The honest answer is the builder's knob lock and a light deadbolt from when the house was new.

    Lock Replacement & Upgrade

    Someone tried the back door while you were away. The jamb is splintered around the strike, the bolt is bent, and the knob turns with a grinding feel.

    There is a hole where the cylinder used to be. Somebody twisted it out of the deadbolt with a wrench, and now the empty bore looks straight through to the kitchen, with the bolt still stuck in the frame.

If You are renting, and the landlord says the locks were never changed.

Then Ask the landlord to have the locks rekeyed.

Tenants generally need the owner's agreement, and most landlords are glad to do it when asked plainly.

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 London were built in 1980 or earlier, according to the 2021 Census.Where most homes were built decades ago, doors often still carry their original mortise locks and brass knobs. That hardware can usually be cleaned, re-sprung and kept in service, with a modern deadbolt added above it for strength without losing the look.
  • Single-detached houses make up about 49% of homes in London (2021 Census).Where the housing is mixed, expectations about what can be changed differ. A homeowner in a house decides everything; a condo owner works within house rules on the outer face. The locksmith knows which conversation to have at which door.

Let's clear a few things up

How often should a business change its keys as a matter of routine?

There is no fixed interval. Rekey on events rather than on a calendar: a key not returned, a lease change, a break-in, a renovation crew finished, or a key count that no longer matches the register. Businesses with a good register and a restricted keyway often go years between rekeys because nothing prompts one. A yearly check of the register against the keys on the hook is the habit that tells you when the time has come.

What condition does a lock need to be in to be rekeyed?

It needs a plug that rotates without catching, pins that return under their springs, and a face free of heavy corrosion or cracks. Most commercial cylinders in daily use pass easily. Ones that are stiff, gritty or green with salt bloom can sometimes be cleaned and repinned, and the locksmith will say when a replacement for that door is the better value; the rest of the doors are rekeyed regardless.

Can the aluminum storefront door on our unit be rekeyed?

Yes. The narrow stile of a storefront door houses a screw-in mortise cylinder secured from the edge, and it unthreads, is repinned and screws back in like any other. What the locksmith watches is the cam: it has to suit the hook or deadbolt mechanism inside the door and sit at the correct depth, or the bolt throws short. Weather-facing cylinders showing salt wear are pointed out so you can decide on replacement.

Do I need to replace my whole deadbolt or just the cylinder?

It depends on what you have. If the deadbolt is a good heavy unit that throws a full inch into a proper strike, a high security cylinder can replace the ordinary one and the rest stays. If the deadbolt is light, worn or throws a short bolt, a new graded deadbolt with a hardened bolt is the sensible base and the high security cylinder goes into that. The assessment tells you which, door by door.
