Preston Locksmith Co.

People sometimes ask why anyone chooses locksmithing. The honest answer is that it is one of the few trades where you see the problem solved while the customer watches. A family that could not get in is inside. A shop that had a door propped open now has one that closes and locks. A driver with a snapped key has one that turns. That satisfaction is why the company exists, and it shapes how we treat people. We arrive prepared, we explain what we are doing, we respect the property and we leave things working. It is simple work done carefully, and we are proud of it.

Shop rules

Honest advice about your locks.

  1. Plain words. We talk about pins, cylinders and strikes only when it helps you understand. Otherwise it is 'this is why the door sticks and here is what fixes it'.
  2. Respect for your door. We treat an old wooden door or a new steel one as yours, not as a project. Non-destructive methods come first, and we ask before drilling anything.
  3. Knowing what you are left with. Before we leave, you will know exactly what changed, how many keys exist and what to keep an eye on. Nothing is left as a mystery.
  4. Open 24/7, same fees any hour. Talk to a locksmith about it.

On every job

  1. Rule of the job1 of 3

    Identifying the small lock

    Mailbox, cabinet and desk locks are small but varied. We identify the type and whether a key can be made, a cylinder replaced or the whole unit swapped.

  2. Rule of the job2 of 3

    Replacing or rekeying it

    Most small locks are replaced rather than repaired because new parts are simpler than rebuilding tiny mechanisms. We fit the new cylinder and check the cam lines up with the catch.

  3. Rule of the job3 of 3

    A tested key and a spare

    You get a tested key plus a spare, and a tip about where to keep it, because a mailbox key is the one people lose most.

How a visit goes

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…

    Respect for your door
