Locks that are not on a front door

Most locksmith calls are about a house, an office or a car. A steady share are about everything else: a safe that will not open, a filing cabinet with no key, a mailbox, a storage unit, a bike lock, a laundry coin box, a display case or an antique desk. These jobs use the same skills, but each type of lock has its own construction, its own rules about who can authorize the work, and its own sensible limits.

This page is a guide to those services. Each section links to a page with the detail.

Safes are opened, serviced and re-coded rather than broken into wherever possible. A safe with a forgotten combination or a failed electronic keypad can often be opened without damage, and the lock can then be reset or replaced so the safe is usable again.

Work on safes includes:

Proof of ownership is required before a safe is opened. For a safe in a rental property, an estate or a business premises, the person who owns its contents authorizes the work.

03

Cabinets, desks and cam locks

01

Filing cabinets, desks, lockers, display cases and many mailboxes use cam locks: a small cylinder that turns a flat metal cam behind the door. They are measured by the cylinder length and the cam shape, and they can be keyed alike so one key opens a whole office of cabinets.

Mailboxes

Mailbox locks are cam locks with an extra question attached: who is responsible for the lock. A private mailbox on a house belongs to the owner. In apartment and condo buildings, the mailbox locks usually belong to the landlord or corporation. Canada Post community mailboxes are handled by Canada Post.

When the lock is yours to change, a broken key can be removed and the cylinder replaced or rekeyed. The details are on mailbox lockouts and broken keys.

05

Storage units and moving trucks

Storage facilities each have their own rules for opening a unit when the key or code is lost. Most require the tenant to show identification and the rental agreement at the office first, and some require their own staff to be present. We open the lock only once the facility has confirmed the tenant's right to the unit. See storage unit lockout service and, for U-Haul units and trucks, U-Haul storage lockout.

Operators of storage facilities have a different set of needs, from overlock systems to master-keyed cylinders. Those are covered on self-storage facilities: locks and access.

When a bike lock key is lost, the lock can usually be picked, decoded or cut, depending on its type. A light cable lock and a hardened U-lock are very different jobs. The person asking needs to show the bike is theirs, typically a purchase receipt, a registration record or a photograph of themselves with the bike. See bicycle lock out service, and for choosing a better lock afterwards, choosing a bike lock.

07

Laundry coin boxes and appliance locks

01

Coin-operated washers and dryers in apartment buildings and laundromats use small high-security cam locks on the coin box. Owners and building managers call when keys are lost, a lock is jammed, or keys have been held by too many people. Coin-box locks are usually rekeyed or replaced as a set, and the keys are kept under tighter control than suite keys. See washing machine locks.

08

Antique and heritage hardware

Older homes and furniture carry hardware that is no longer made: mortise locks with skeleton keys, rim locks, warded cabinet locks and decorative escutcheons. These can often be cleaned, repaired and fitted with new keys rather than replaced.

09

Safe deposit boxes

Describe your door →

A lost safe deposit box key is handled through the bank, which controls the box and decides how it is opened. Executors dealing with a deceased person's box need the bank's process as well. See lost safe deposit box key.

10

Garage keypads and smart doorbells

01

Wireless garage door keypads, smart doorbells and similar devices sit at the edge of lock work. We replace and set up keypads, change codes, and fit smart doorbells, and we make sure the device does not interfere with the lock on the door it sits beside. See garage door keypad and smart doorbell installation.

11

What to tell us

Describe the lock as well as you can: what it is fitted to, any brand or code stamped on it, whether you have a working key, and what has gone wrong. A photograph of the lock face and the key often tells us what the job involves before anyone arrives. Have proof of ownership or authorization ready, because every one of these jobs requires it.

Can a safe be opened without destroying it?

Often, yes. Many safes with lost combinations or failed keypads can be opened without damage, and the lock can then be reset or replaced.

Can a filing cabinet key be made without the original?

Often. Many cabinet locks have a code stamped on the face, and a key can be cut from that code.

Who can change a mailbox lock in an apartment building?

Usually the landlord or condominium corporation, because they own the mailbox locks. Canada Post community mailboxes are handled through Canada Post.

What do I need to get a bike lock removed?

Yes. They are usually rekeyed or replaced as a set, with the keys kept under tighter control than ordinary building keys.

Can you help with a lost safe deposit box key?

The bank controls the box and its opening process, so contact the bank first. We can explain what usually happens and what executors need.
