Gate & Building Entry Locks in Mississauga
A neighbour mentions, in passing, that the key from three tenants ago still lets him into the building's front door.
In plain words
Hardware bolted to a gate or an exterior building door lives outside every day of the year, which is a different job from a lock tucked behind a storm door. This service treats that exposure as the starting point: cylinders rated for weather, fasteners that resist road salt, and a closer set up to keep working through a freeze-thaw cycle rather than seizing at the first cold snap. The result is a gate or entry that keeps operating through the season it is most likely to struggle in.
How the visit goesEvery time the courtyard gate closes, it slams hard enough to rattle the fence panels, and the deadlatch never quite drops into the keeper before the spring yanks it the rest of the way. One good gust of wind and it bounces right back open.

How the visit goes


Reading how the gate or door actually moves
Before touching the lock, the locksmith watches the gate or door open and close by hand: how far it swings, whether it drags, sags or springs back with too much force, and where the latch lands relative to the strike. A gate held shut with a brick or a door propped for the mail carrier is a clue about what the lock is being asked to work against every day. This first look decides whether the real fix sits in the hardware, the hinges, or the frame the whole assembly hangs from, and it shapes every choice made afterward.
Working on the cylinder itself
Depending on what the assessment found, the cylinder is either rekeyed, replaced with a weather-rated unit, or decoded so a fresh key can be cut to match it. Rekeying removes the existing pin combination and sets a new one, so old keys stop working while the same housing stays on the gate. A full replacement suits a housing that is worn, pitted or the wrong grade for outdoor use. Either way, the new or updated cylinder is cycled repeatedly with the new key, from both sides where the hardware has two, before it is considered finished.
A seasonal habit worth keeping
A gate or shared entry that was serviced once benefits from a short look each season afterward, particularly heading into winter: cycling the gate to check the closer still settles it into the latch, glancing at the cylinder for the first signs of pitting, and confirming hinge or post hardware has not worked loose. Catching a stiff cylinder or a slow closer in the fall is a smaller job than reaching the same gate once it is genuinely frozen or has sagged further over a winter of neglect.

What affects the quote
Materials the gate or frame is built from
Wood, wrought iron, aluminum and vinyl gates each take fasteners and mounting approaches suited to that material, and matching the lock and closer correctly to the gate's construction is part of what the quote covers.
Time of year and weather on the day
A cylinder frozen solid or a closer stiffened by cold takes patient work before adjustment or replacement can even begin, so a call made during a cold snap is quoted with that extra time in mind.
Any upgrade chosen while the locksmith is already there
Some property owners use the visit to move to a heavier closer, an electric strike, a master key system or additional padlocks for other gates. None of this is required to address the original problem; each option is priced as a separate line.
What to have ready
- Is the gate wood, metal, aluminum or vinyl?
- Is the lock dragging, slamming, stuck, or simply not latching?
- Do you manage this property, or should someone else be involved in the decision?
Gate & Building Entry Locks: questions
QuestionsDoes this service cover the gate itself, or only the lock?
Both, where the two are connected, which on a gate they usually are. A locksmith working on a gate lock also looks at the hinges, the post and the closer, since a lock rarely fails on its own when the real cause is a sagging gate or a post that has shifted. Work that goes beyond hardware the locksmith carries, such as rebuilding a rotted post or a damaged fence panel, is flagged so it can be handled by whoever normally does that kind of repair.
What is a good option for a gate that delivery drivers or a maintenance crew need occasional access to?
A keypad or a lockbox with a rotating code works well there, since access can be shared without handing out a physical key that has to come back later. A weather-rated cylinder with a separate access key is another option if the property already runs on a keyed system. The locksmith can talk through how often the code should change and who on site should know it, so the gate stays convenient without staying open to everyone.
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.
