- The call
- The property manager mentioned that half the compartments in the lobby's mailbox panel are original to the building and are starting to fail one by one, key by key, as tenants turn over year after year.
You've just moved in, and the mailbox compartment in the lobby came with a single key the previous owner mailed back separately, or never handed over at all. As far as anyone can tell, the lock still answers to a stranger's key.
In plain words
When the real concern is who else might hold a key, replacement settles it at the root. The old cylinder comes out, a new one goes in with a cam cut to match the compartment door, and two fresh keys are handed over on the spot. Whatever key was floating around before, lost, borrowed, or left behind by someone who moved out, stops working the moment the new lock is seated and tested.

How the visit goes
Scene 1
What became of the old key
The history of the missing or failing key shapes how the visit proceeds. A key still at home but simply worn down is a routine swap. A key lost out in the world, taken by someone who used to live there, or never handed over at a move-in changes the urgency, since a stranger may still be holding something that opens the compartment. A snapped key adds a short extraction step before the old lock comes out. Every version starts with the same honest question: where did the key actually go?
Scene 2
Working through a full panel
When a property manager has asked for several compartments changed together, each one is still confirmed against the unit number or resident it belongs to before its lock comes out, and the work moves door by door rather than as one blanket swap. Compartments stay keyed separately from each other unless a resident specifically asks for their mailbox and another lock to share a key. A panel-wide visit closes with a simple list: which compartment received which lock, and how many keys went to each person.
Scene 3
Knowing who to call next time
After this visit, it helps to remember which kind of mailbox is on the property. A private box, a house's mail slot, or one compartment in a building's own panel is this service's territory going forward. A mailbox serving a whole street belongs to the postal operator, which issues its own replacement keys and handles its own lock problems directly, so a future issue with that kind of box is a call to them rather than a repeat visit here.

What shapes the quoteMarkland Woods Locksmith Co.
- Whether drilling is needed
- Most old locks come out with a wrench or a screwdriver from inside the compartment. A seized or damaged cylinder that has to be drilled adds a step, along with the new lock needed to replace it.
- Corrosion or ice
- A lock stiffened by rust or frozen solid needs patient freeing before it can even be assessed, which adds time compared with a lock that opens and closes normally.
- Any additional hardware requested
- Some households ask for a small parcel locker upgrade or a second compartment added to the request while the locksmith is already there, and each addition is its own line beyond the original lock swap.

Frequently asked questions
Can a frozen mailbox lock be opened without breaking it?
Usually, yes. A penetrating lubricant or a lock de-icer given a little time to work, combined with gentle movement of the key or a light pick, frees most iced-up compartment locks without forcing anything. Hot water is avoided, since it can refreeze inside the mechanism. Once it turns freely, the lock is inspected and, if it shows wear or damage, replaced with a fresh one lubricated as its own maker specifies, since a lock that has frozen once can repeat the pattern.
Does road salt or winter weather affect these small locks?
It does. Outdoor cam locks sit exposed to spray, salt, and repeated freezing all winter, which corrodes the small internal parts faster than indoor hardware and can leave a keyway gritty or a cylinder stiff well before it actually fails. Whatever lubricant that cylinder's own maker specifies, used once or twice a year, helps a replacement lock last through more winters.
What happens to the old lock and the old key afterward?
The old cylinder is removed and handed to you or taken away, whichever you prefer, and any key still floating around no longer fits anything once the new lock is seated. If the old lock was drilled out, the leftover pieces are shown to you so it is clear what was removed and why.

2021 census: what it means at the door
Every square is one home in a hundred.
- 38 in 100 homes · mixed ages
- 37 in 100 homes · mostly attached
- About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.In an area where homes span several eras, one street may have original mortise locks and the next builder-grade cylinders. A locksmith working here carries parts for both, so whichever door he meets, the job finishes in one visit.
- Single-detached houses make up about 37% of homes in Mississauga (2021 Census).In buildings, the suite door often has a closer and a heavy frame, and the deadbolt sits in a metal or metal-clad door. A locksmith fitting or rekeying one brings the tools and cylinders that suit that construction rather than a wooden house door.
