A locksmith emergency rarely announces itself. Most happen at inconvenient moments — late at night, in bad weather, in an unfamiliar part of the city — and knowing what to expect can make all the difference. GTA Lockman Mobile Locksmith Services responds to hundreds of calls across Toronto and the Greater Toronto Area every month, and the same situations come up again and again.
This guide covers the eight most common locksmith emergencies in Toronto, what causes them, what to do when they happen, and how a professional mobile locksmith handles each one.
The single most common call. Keys inside the vehicle, fob battery dead, or a broken key in the ignition — all resolved without damage by a trained automotive locksmith.

Car lockouts account for the largest share of mobile locksmith calls across the GTA. The most common scenario is keys left inside a locked vehicle — in a parking lot, at a gas station, or outside a home. Other frequent causes include a key fob battery that dies unexpectedly, a key that breaks off in the door lock, or a transponder key that loses its programming and no longer starts the vehicle.
What an Automotive Locksmith Does
A trained automotive locksmith uses specialized tools to open the vehicle without touching the glass or damaging the door seals. For newer vehicles with electronic locking systems, the technician uses equipment that interfaces with the car’s system directly.
If the key is broken in the lock or ignition, extraction tools remove the piece cleanly. A new key can then be cut and programmed on site for most common makes including Honda, Toyota, Ford, GM, Hyundai, and others. See the full car key replacement service for details.
Prevention tip: Having a spare key stored somewhere accessible — with a trusted person or in a secure key lockbox — eliminates most car lockout situations entirely. A car key programmed as a backup costs far less than an after-hours emergency call.
2 Residential Home Lockout
Getting locked out of your home is the second most common locksmith emergency in Toronto. It happens to renters, homeowners, and condo residents alike — often after returning late, during a move, or when a key breaks in the front door lock. Condo buildings with key fob entry add another layer of complexity when the fob stops working or is lost.
Check all entry points first
Before calling, check every door and window. A back door, patio door, or garage entrance may be unlocked. Condo residents should check with the building’s concierge or superintendent, who may be able to provide access.
Have ID ready when the locksmith arrives
A professional locksmith will ask for identification confirming you live at the address before opening the door. This is a standard security protocol — not something to be surprised by.
Consider rekeying after the lockout
If you were locked out because a key went missing rather than just forgetting it inside, rekeying the lock is a practical follow-up. It costs less than a full lock replacement and ensures the missing key no longer works.
GTA Lockman Mobile Locksmith Services covers Toronto, Mississauga, Markham, Brampton, and surrounding areas.
3 Broken Key in a Lock or Ignition
Keys break more often than most people expect. Worn keys, cold temperatures, and applying sideways force when the lock is stiff are all common causes. When a key snaps inside a residential deadbolt, a car door, or a vehicle ignition, the broken piece needs to be removed before the lock can be used again.
Do not attempt removal with pliers, tweezers, or a nail. These tools almost always push the broken piece deeper into the lock cylinder or scratch the interior, making professional extraction harder and sometimes requiring full lock replacement instead.
A locksmith uses thin extraction picks designed specifically for this purpose. The broken piece is removed without disassembling the lock in most cases. Once clear, a new key can be cut from the lock’s code or from a remaining portion of the original key.
4 Lost or Stolen Keys
Losing your keys is an inconvenience. Having them stolen is a security concern. The appropriate response depends on the circumstances, but in either case, acting efficiently protects you.
When keys are lost
If your keys were lost somewhere inside your home or are genuinely misplaced, rekeying the affected locks is usually sufficient. Rekeying changes the internal pin configuration so that the lost key no longer operates the lock, while giving you a fresh set of working keys. It is reliableer and less expensive than replacing the entire lock hardware.
When keys are stolen
If keys were taken during a theft, mugging, or from a vehicle break-in, treat it as a security issue. Rekeying or replacing all affected locks as soon as possible closes off any window of access. If there is any indication the stolen keys have an address attached — such as a key fob that displays your license plate or a key ring with a return address — prioritize the lock change that same day.
Rekeying vs. Lock Replacement
Rekeying works when the existing lock hardware is in good condition and you simply need the old key to stop working. Lock replacement makes more sense when the hardware is worn, you want to upgrade to a higher-security grade, or you want a new deadbolt installation as part of a broader security upgrade.
A locksmith can advise which option makes more sense for your specific situation on the same visit.
5 Emergency Response After a Break-In
A forced entry leaves more than a broken lock — it leaves your property unsecured until a professional can respond. After a break-in, the professional priority is getting the door or entry point secured, followed by lock replacement and any necessary repairs to the door frame, hardware, or glass.
GTA Lockman Mobile Locksmith Services handles post break-in calls across Toronto and provides emergency door repair and lock replacement on the same visit. If the door frame or glass was damaged during the break-in, temporary boarding can be arranged while permanent repairs are scheduled.
After a break-in, consider upgrading to a higher-grade deadbolt or adding a latch guard to reinforce the door against future forced entry attempts. These additions significantly increase resistance to kick-in attacks, which account for most residential break-ins in Toronto.
6 Commercial and Business Lockout
A commercial lockout has direct operational impact. Staff locked out of an office, retail location, or warehouse at opening time cannot work, and customers cannot be served. Commercial locks — including mortise locks, storefront systems, panic bars, and access control hardware — require a locksmith with specific commercial experience and tools.
GTA Lockman Mobile Locksmith Services handles commercial lockouts for offices, retail businesses, and industrial properties across Toronto, Mississauga, Markham, and Etobicoke. The commercial locksmith service covers lockouts, lock replacements, rekeying, and master key system installation.
GTA Lockman Mobile Locksmith Services responds to commercial calls across Toronto and the surrounding municipalities.
7 Eviction Day Lock Change in Ontario
Eviction day lock changes are a specific type of locksmith call that follows a formal legal process in Ontario. Under the Residential Tenancies Act, landlords must have a valid eviction order from the Landlord and Tenant Board and enforcement by a Sheriff before changing locks. A lock change cannot happen before the official eviction is carried out.
Once the eviction is legally enforced, a locksmith can change the locks on the property. This typically involves replacing all exterior entry locks and providing the new keys to the property owner. GTA Lockman Mobile Locksmith Services handles these calls with an understanding of the legal requirements involved.
Important for landlords: Changing locks before a legal eviction order is enforced by a Sheriff constitutes an illegal lockout under Ontario law and can result in significant penalties. Always confirm the eviction process is complete before contacting a locksmith to change the locks.
For tenants who have been legally evicted and need access to retrieve belongings, the process is governed by the LTB order. A locksmith’s role in these situations is limited to the physical lock change itself — legal questions should be directed to the LTB or a legal aid clinic.
