Gate & Building Entry Locks
The gate to the side yard used to close with a satisfying click. After a winter of frost heaving the fence post, the latch now sits a full inch below where the strike is waiting for it, and the gate swings free no matter how hard it is pulled shut.
Gate & Building Entry Locks
In plain words
Some building entries add a buzzer, a keypad or an electric strike to the mechanical lock, and any one of those pieces can be the reason a door stops releasing on cue. This service checks the wiring, the power supply and the mechanical override together with the lock itself, rather than assuming the fault sits wherever the last person guessed. Whatever combination of electronic and mechanical hardware the entry uses, it leaves working as one system: a mechanical key still able to open it wherever the installed lock provides one, and a fail-safe strike or maglock still releasing on its own if the power ever goes out.
How the visit goesA neighbour mentions, in passing, that the key from three tenants ago still lets him into the building's front door. Nobody changed it after he moved out, and now the property manager wants to know exactly how many keys are still floating around out there.

How the visit goes
Taking stock of who holds a key
On a shared entry, the lock is only half the picture; the other half is who currently has a working key. The locksmith asks how many units or households rely on this door, whether anyone has moved out without returning a key, and whether other gates or entries on the property are meant to share the same one. That inventory decides whether a straightforward rekey covers everyone or whether some doors need to be brought onto a common key during the same visit, so nobody is left holding a key that no longer opens anything.
Repairing damage from an earlier attempt or a break-in
Where the gate or door shows signs of prying, cutting or a spun cylinder, the damaged hardware is removed and assessed on its own before anything is rebuilt: a bent strike is straightened or replaced, a compromised cylinder is swapped rather than trusted, and a cut hasp or shackle is replaced with a heavier one if the original was clearly overmatched. The surrounding wood or metal gets checked too, since forced entry often stresses the frame as much as the lock. The finished gate or door is tested to confirm it closes, latches and locks exactly as it should.
Everyone currently there has a matching key
If the visit involved a rekey, every current resident, tenant or key holder leaves with a key cut to the new combination, and a short written note of who received one. Anyone who moved out before the change is now holding a key that no longer fits whichever gate or door was rekeyed, though it may still turn any other cylinder on the property that kept its old combination. Where several gates or doors were brought onto the same key, each one is tested in your hand before the locksmith leaves, so you are not left guessing which key opens which gate the next time you need one after dark.

What affects the quote
Same fees day, night or weekend
1Master key or keyed-alike planning
Setting up a master key system, or bringing several separate locks onto one shared key, involves planning the pinning structure across every cylinder involved, which is more work than rekeying one lock in isolation.
2Any damage from a prior forced entry
Where pry marks, a bent strike or a cut hasp are found, repairing or replacing that damaged hardware is additional to a routine lock adjustment, and the locksmith points out what was already there before quoting it.
3Whether the property manager or a board is involved
Work on a shared building entry sometimes needs sign-off from a property manager or condo board before proceeding, and coordinating that approval, along with providing a record of the work for their files, is part of the visit.
Gate & Building Entry Locks: questions
How should I look after a gate lock so it keeps working?
Twice a year, work the lubricant the cylinder maker specifies into the keyway and cycle the key a few times; the wrong product for that model can collect grit or gum up the mechanism instead of helping it. Check that the closer still settles the gate into the latch without slamming, and look at hinges or post hardware for movement, especially after a hard winter. A cylinder that starts needing a wiggle, or a gate that has begun to drag, is worth addressing while it is still a small adjustment.
A tenant moved out of our building. Do we need to rekey the shared entry?
It is worth doing, since a move-out is exactly the situation a rekey is meant to cover: a former tenant's key still operates the same lock everyone currently living there relies on. Rekeying resets the cylinder to a fresh combination and issues new keys to current residents, without requiring a whole new lock in most cases. Bringing any other gates or doors that share that key along at the same time keeps the whole property on one current combination.
What actually happens during a gate or building entry lock visit?
The locksmith first watches the gate or door move and checks the hardware fitted to it, then works out whether the issue sits in the lock, the closer, the hinges or the alignment of the frame itself. Whatever combination is found, the relevant piece is adjusted, rekeyed or replaced, and the whole assembly is cycled repeatedly afterward to confirm it closes, latches and locks the same way every time. Any keys involved are cut and tested before the visit is considered complete.
