Good to know

Yes, and these are usually gentle jobs. Privacy locks on bathroom and bedroom doors are built with a small emergency release on the outside, and when that has been painted over or stripped a locksmith can still operate the latch from outside with the right tool. Older interior doors with a keyed mortise lock or a bit key are opened by picking or by cutting a key to the lock. The door and trim stay as they were. Home Lockout Service

Yes, and usually without disturbing the access system. Many readers and electric strikes go dark because a power supply, breaker or backup battery has failed, and restoring power reopens the door. Where a mechanical override cylinder is fitted, it opens like any other lock; not every system includes one. An ordinary magnetic lock releases on its own once its power is actually removed, so a genuine power loss opens that door without waiting on a remote release. Afterwards, credentials and schedules are confirmed with whoever manages the system. Business Lockout Service

Usually. Laid end to end, the halves show the full set of cuts and identify the blank, and a locksmith reads them with a gauge and cuts a fresh key to those depths on a code machine. That is better than tracing the broken blade on a duplicator, because a worn key copied is a worn key repeated. If a spare or the key code exists, that is used instead. Broken Key Extraction

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. Break-In Damage Lock Repair

Often, but check with your property management first. Condominium corporations have a right to enter a unit on reasonable notice, and without notice in an emergency, and many buildings ask that suite doors stay on a system the corporation can open or that a key be lodged with management. Lobby, garage and locker-room doors belong to the corporation and are theirs to manage. A locksmith will ask about your building's rule and work within it. Lock Rekeying

Very little is needed. Each spring and autumn, lock the door from inside and feel whether the bolt still goes home without the door being pulled; if it hesitates, the door has moved with the season and a small strike adjustment restores it. Whatever lubricant the lock's own maker specifies keeps it smooth, often a dry PTFE or graphite type in the keyway and along the bolt, though some cylinders are meant to be serviced with oil. In winter, wipe road salt off the outside trim to protect the finish. Deadbolt Installation

Yes. Manufacturers make deadbolts, handlesets, knobs and levers in matching finishes and styles, so a replacement deadbolt can sit above your existing handle without looking like an afterthought. Bring or photograph the hardware you want to match, including the interior side, and note whether it is a warm brass, a satin nickel, an oil-rubbed bronze or a matte black. Where an exact match is not made, the locksmith suggests the closest family. Lock Replacement & Upgrade

Often, yes. Locksmiths who work on older hardware keep salvage and reproduction trim in the common patterns and finishes, and a knob, rosette or escutcheon can usually be found close enough that the pair on one door match. Where nothing suitable exists, the trim from a less visible door can be moved to the entry and the reproduction fitted where it is seen less. Bring or photograph the surviving piece so it can be matched. Vintage Mortise Lock Service

A relocker is a small device inside some safes built to jam the bolt work until a trained technician services it, if the case is drilled in the wrong spot, dropped, or exposed to fire, as a defence against forced entry. If one has tripped, the fix is mechanical: freeing or replacing the relocking mechanism, rather than another attempt at the combination. Recognizing a tripped relocker early changes the plan from the first visit rather than after several failed attempts. Safe Opening & Combination Change

Yes, provided the spot chosen still allows full anchoring and enough clearance for the door to swing open completely. A closet floor, the back of a built-in cabinet, or a recessed wall cavity can all work, though each limits the size of unit that will actually fit and reach the anchor points properly. Balancing concealment against how often the safe gets opened is worth discussing before a spot is chosen. Safe Installation & Servicing

An authorised person contacts the locksmith who holds your system, quotes the system reference, and the key is cut from code and numbered into the register. Some systems use a physical authorisation card, others an online validation, and business systems often require a signature that matches one on file. The key is collected or delivered, and the record shows the new total. It is deliberately not something a stranger with your key can do. High Security Locks

Mechanical rekeying leaves electronics alone: alarm panels, card readers and keypads keep their codes and credentials. What changes is the list of people holding keys, and it is worth updating the alarm company's keyholder list and retiring the codes of anyone who has left at the same time, since keys and codes usually walk out together. Where a door has both a card reader and a keyed override, the override cylinder is rekeyed with the rest. Commercial Rekeying

Usually yes, if spare capacity was planned into the keying platform from the start. A new hire is normally handed a copy of the bitting their role already calls for, and a realistic new door can be pinned to accept a combination already reserved for that purpose. A system pinned to its absolute limit on day one has less room to grow, and adding a level to existing doors later can mean repinning cylinders that are already in daily use. Master Key System Design

A standalone unit is a self-contained reader and lock at one door, holding its own list of credentials, though it can still need a power or network connection to run. A networked system ties several doors to shared management, sometimes through more than one controller, aggregating schedules and combining logs across all of them. The right choice depends on how many doors need controlling and whether the business wants a single place to manage all of them, rather than one being universally better. Access Control Installation

It depends on the pair. Some latch independently and need nothing extra. Where the hardware calls for a set closing order, a coordinator lets the two leaves close in the right sequence, letting the active leaf's device seat properly into a strike carried on the inactive leaf, or into an astragal. Alternatively, the centre mullion can be removed and a vertical-rod device fitted to each leaf, turning the pair into one wide exit. Whichever applies, both leaves are tested working together, not one at a time. Panic & Exit Hardware

Yes. Trucks and vans often have a separate cargo or tailgate lock, motorhomes use household-style cylinders on their living-space doors, trailers and hitch locks are padlock-type hardware, and motorcycle seat and steering locks are small wafer cylinders. Say what the vehicle is when you call so the right picks and blanks are in the van, and expect the same authorisation check for each. Car Lockout Service

Yes, for a vehicle that genuinely has no immobilizer, checked by VIN and equipment rather than assumed from age, since several early-2000s vehicles already shipped with a factory immobilizer and coded key. Where that is the case, it is the simplest key work there is: a blade cut to the factory code from the VIN or to a reading of the door lock, rather than copied from a worn original. If the ignition has become sloppy, the locksmith can rebuild it in the same visit. Car Key Replacement

This is a common and straightforward call. The locksmith works from the single existing key and the vehicle itself, identifying the blade profile and reading or matching the chip, then testing the result on its own before the visit ends. It is also a good moment to confirm how many keys the car's history suggests should exist, since a private sale sometimes changes hands with an unknown key already out of circulation. Spare Car Key Duplication

Ownership of the vehicle is confirmed first, since a fob is only added for someone who can show they now hold the vehicle. From there, an additional fob is sourced and registered alongside the one you have, or, if you would rather not rely on a single fob at all, a second and third can be added in the same visit.
