Small things that matter
You do not need to become an expert to make good choices about locks. A little understanding goes a long way. These short pieces give you that: how keys are copied, what a lock grade means, when a repair beats a replacement and how to prepare for the unexpected.
Your questions, our answers
Is a double-cylinder deadbolt a good idea after a lockout?
A deadbolt keyed on both sides is sometimes suggested for doors with glass beside them, but on a main escape door it means finding a key to get out. A door people use to leave the home should open from the inside without a key or special knowledge, especially in an emergency. A single-cylinder deadbolt with a thumb-turn, paired with a reinforced strike and a proper glass film if needed, keeps both security and a clear way out.
Can you also deal with the back door, the roll-up shutter and the gate?
Yes. A business lockout covers every opening the premises relies on: the rear service door with its exit device, a roll-up shutter and its padlock, the compound gate, a mailbox in the lobby and interior doors such as the cash office or server closet. Mention each one when you call so the right padlock shackles, cores and cylinders are in the van, and so cylinders that should share a key are handled together.
Part of the key is sticking out. Can I just pull it with pliers?
If a good length shows and the plug is at its normal rest position, a firm straight pull sometimes works. The risk is pushing instead of pulling, or twisting, which drives the piece deeper and can bend a pin. If it does not come on the first gentle try, stop there and leave it for extractor tools, which grip the cuts without loading the cylinder.
What is a security strike box and why fit one?
A security strike is a heavier plate with a formed steel pocket that wraps around the bolt instead of leaving it in bare wood. It is set into the jamb and fixed with long screws, typically three inches, that pass through the jamb and the shim space into the framing, with the longest screws placed nearest the door stop where the bolt bears. Manufacturers specify the pocket depth so the bolt extends fully. The result spreads a kick across the wall stud rather than two small screws.
Why does the lock only stick when the door is closed?
Because with the door open the bolt is throwing into thin air, and with the door closed it is throwing into a pocket that has moved. A door that has dropped on its hinges, swollen with humidity or been pushed out by thick weatherstripping lands the bolt against the edge of the strike plate instead of through the hole. A chalk mark on the bolt shows exactly where it hits, and the fix is on the frame, not in the cylinder.
My key fell in the snow in my own yard. Do I still need to rekey?
It is your call, and it is a reasonable one either way. A key lost on your own property is unlikely to be picked up by a stranger, but it will surface in the spring thaw, and until then you are trusting a guess about where it lies. Many households rekey anyway for the certainty, and because the visit also lets them put every door on one key while the locksmith is there.
How is rekeying different from replacing the lock?
Rekeying keeps your existing deadbolt or handle set and gives it a new key, commonly by changing the pins inside, though some cylinders reset a different way. Replacing removes the whole lock or cylinder and fits new hardware. Rekeying suits locks that are in good condition and simply need a fresh key. Replacement is the better call for hardware that is worn or damaged, built to a low grade, on a keyway the other doors cannot share, or due for a change of style or a keypad.
Someone forced my door. Can the new deadbolt go into the same frame?
In most cases, yes. The locksmith examines the jamb for splits and stripped screw holes, glues and pins any cracked section, and fits a full-length jamb reinforcer under the strike so the new long screws bite into sound wood and the stud behind. A new pocket is bored to the correct depth. Where the jamb is beyond repair, replacing that section of frame is discussed before any lock goes on.
Can you replace the lock on a sliding patio door or French doors?
Yes. Sliding doors take a replacement mortise hook lock sized to the rail, often with a keyed exterior, and benefit from a secondary foot bolt or a pin through the frames. French doors are secured by treating the inactive leaf properly with flush bolts into the head and sill, then fitting a deadbolt to the active leaf with a strike into that reinforced edge. Both are routine parts of a residential upgrade.
Can my interior doors be serviced too, and can one key work all of them?
Usually yes to the first, and to the second once the locksmith checks the locks. Interior mortise latches with privacy turn buttons are lighter versions of the entry lock and respond to the same clean and re-spring. Interior locks in a house were sometimes supplied to one bit key, and where the key sections, warding and levers actually match, the locksmith can restore that arrangement so a single key opens several bedroom and bathroom doors. It is a practical thing to have when a child locks a bathroom from inside.
The house came with a smart lock. Can you make it mine?
Yes, and it is treated as a fresh installation rather than a hand-me-down. The lock is reset to factory settings using the maker's procedure, which wipes codes, schedules and paired phones, then enrolled to an account you create. Anything else that could open it, such as a hub or a voice assistant, gets its own check, because those permissions sit outside the lock. The override cylinder is rekeyed, batteries replaced and firmware updated. If the hardware is worn, replacing it is the cleaner choice.
I rent my unit. Can I request gate or entry lock service myself?
You can certainly call about a problem you are experiencing, such as a side gate that will not latch or a buzzer that stopped working, and the locksmith will look into it. Where the fix touches the shared entry everyone in the building relies on, rather than something specific to your own unit, the work is usually coordinated with whoever manages the property, since a rekey or replacement there affects every current resident, not just the person who noticed the problem first.
What is the difference between a private mailbox and a building's mailbox panel?
A private mailbox, whether a standalone box at the curb or a slot in a house door, belongs entirely to that home. A building's mailbox panel groups many small locking compartments in one frame, usually in a lobby, with each compartment assigned to a unit. The lock itself works the same way in both cases; what differs is who confirms the change and how many other doors sit nearby.
Can a safe be repaired instead of replaced after drilling?
Often, yes, particularly for a mechanical lock, where a worn wheel pack, drive cam or spindle can be replaced individually within the existing lock body. An electronic lock's circuit board and keypad are less often repairable in place and are more commonly swapped for a comparable or higher-rated replacement unit that fits the same cutout.
Can a safe hold both cash and paper documents at the same time?
Yes, though it is worth knowing the interior conditions suited to each are slightly different. Paper gains real heat protection from a fire-rated lining, but that same sealed lining traps humidity, so paper stored inside needs the same periodic airing and a desiccant packet as any fire-rated interior. Cash and other valuables mainly need the tool resistance of the body and door and tolerate the sealed environment more easily. A single well-chosen unit can hold both together without conflict, particularly with paper kept in a sealed folder or bag inside.
Can a hardware store or kiosk copy my new key?
No. The blank for a patented keyway is distributed only through the manufacturer's network to locksmiths who hold the system, and the side milling or angled cuts need a machine set up for that line. A kiosk would have neither the blank nor the cut. Extra keys come through your locksmith, cut from code, once an authorised person has approved the order. That routine is a small inconvenience compared with never knowing who has a copy.
Does stamping keys 'do not duplicate' stop people copying them?
Not reliably. The stamp is a request, and any key on a standard blank can be copied by anyone with the blank and a machine. What does work is controlling the blank itself through a restricted keyway, or controlling access to the lock through interchangeable cores and a tight register. Stamping still has a place: a serial code on each key, instead of the business name, lets you track it without telling a finder where it fits.
What does key control actually mean?
It means knowing, at any time, how many keys exist for a given door or level, who holds each one, and how a new copy would be authorized. A master key system supports key control by design, since keys are marked by role, logged by serial, and cut only against the chart, rather than copied informally whenever someone asks for one.
Can visitors or contractors be given temporary access?
Yes, a temporary credential can be issued for a contractor, a cleaner, or a visitor with its own schedule and, where the system supports it, an expiry so it stops working on its own once the job is done. This avoids handing out a permanent code or a key that then has to be tracked down and collected afterward.
How often does this hardware need to be checked?
Fire door assemblies, including their exit hardware, are inspected and tested on a set schedule, and it is practical to check any exit device on the same rhythm even where the door is not fire-rated. A brief check for a stiff crossbar, a latch that no longer seats fully, or a strike that has drifted is enough to catch most wear before it becomes a callout.
How long does commercial-grade lock hardware typically last under heavy use?
It depends heavily on cycle count and how the door is treated day to day, but hardware graded for commercial duty is built to outlast the internal wear that sinks a residential lock on the same door. A delivery door opened hundreds of times a shift will still wear its hardware faster than a quiet office entrance, so grade and use should be matched from the start rather than assumed.
There is a dog inside and the car is getting hot. Who do I call?
Call 911, and the provincial animal protection line if you cannot reach the owner; the province asks the public to report animals left in hot or cold vehicles rather than break glass themselves. Police and animal welfare inspectors have authority to enter a vehicle for an animal in distress. A locksmith can attend as well, and if you are the owner, the same careful opening gets you and the dog reunited with the car undamaged.
After a break-in the doors and ignition are on different keys. Can that be fixed?
Yes. When a door lock is forced and replaced, or an ignition is swapped, the car can end up needing two blades. A locksmith can rekey the replacement cylinder to match the surviving one, so a single key operates every lock again, and cut new keys to that combination. The transponder side is unchanged by the lock work, so your existing programmed keys carry on starting the car once the blades match.
Why does the VIN matter for making a spare key?
The VIN identifies the exact immobilizer generation and lock system your particular vehicle left the factory with, which decides whether the chip can be copied directly or needs to be freshly coded through the diagnostic port, and which blank and blade profile are correct. Two cars that look identical from the outside can use different systems a model year apart, so the VIN removes the guesswork.
How many fobs can be registered to one vehicle?
This depends on the manufacturer, since each vehicle's memory has a set limit built in, commonly enough for several drivers plus a spare. The visit checks how many the specific vehicle allows and how many are already registered, so a household adding another driver knows whether there is room before a new fob is ordered.
Can I have a spare key made before I actually need one?
Yes, and on many vehicles it is one of the more straightforward visits in this service, since a working key already on hand can authorize the new one; a few models instead call for two working keys or a different programming route. The spare is cut, its chip is written in, and both keys are tested before the locksmith leaves, so the spare is proven rather than simply handed over untested.
Do you need to confirm that I own the vehicle before starting?
Yes, and it takes only a moment when the paperwork is on hand. A vehicle permit or registration document matched to identification settles it in most cases. If the vehicle is a rental, a fleet vehicle or belongs to someone else, a lease, a work order or a call to the registered owner fills the gap. This step protects every vehicle owner who might one day call about their own ignition.
How does a locksmith reach the actuator or linkage inside my door?
The interior trim panel is removed using tools shaped to release its retaining clips without marking the panel. On many doors that exposes the cylinder, the linkage rod and the power actuator for individual testing and repair, though some doors keep a carrier plate, water shield or window guide in the way, or use an integrated latch and actuator assembly, and are worked on accordingly.
Do I have to have the original key for you to cut a new one?
No. When every key for the machine is gone, the locksmith reads the lock directly, working out each wafer's depth by picking and reading the cylinder or using a decoder built for that keyway, and cuts a fresh key to the code that comes out of that reading. It takes longer than copying an existing key, since every wafer is read individually, but it produces a key that matches the lock rather than a guess.
