Things worth knowing

Yes. A tenant locked out of their own unit can arrange entry directly, and the identification check is the same: something that ties you to the address, such as a lease, a bill or a piece of mail, plus photo identification. Where you may want to involve your landlord is any change to the lock afterwards, because tenancy rules in this province expect landlords and tenants to agree on lock changes and to share keys. A locksmith can note what was done for the building manager. Home Lockout Service

Usually the link between the cylinder and the bolt. On a storefront lock the cam behind the mortise cylinder can wear or slip out of position; on a lever or mortise lockset the tailpiece or a spring in the deadlatch gives up. Your key is fine and so are the pins, so once the door is opened the fix is a new cam, tailpiece or latch, and your existing keys carry on working. Business Lockout Service

It is a well-known idea and a poor one. A drop of adhesive on the other half rarely bonds to a piece of brass sitting in a tight keyway, and what it does bond to is the cylinder, the pins and the face of the lock. That film then has to be dissolved before proper extractors can slide in. Keep the halves apart and dry. Broken Key Extraction

It is tempting, but a thumb-turn lets everyone in the household leave by that door without hunting for a key, special device or special knowledge, so a keyed inside cylinder is the wrong fix. Better answers are a tested security-film system or laminated glass in the sidelight to slow an arm from passing, moving the deadbolt beyond arm's reach of the glass where the door allows, and a glass-break sensor if you have an alarm. Break-In Damage Lock Repair

Yes. A mortise lock, the kind with a large case set into the edge of the door, uses a threaded cylinder held by a set screw reached from the door's edge. The cylinder unthreads, is pinned like any other and screws back in. Where a very old lock uses a bit key or a lever mechanism instead of a pin cylinder, the locksmith will explain the options, which may include fitting a modern cylinder into the existing case so the door keeps its original hardware. Lock Rekeying

Two measurements decide whether a deadbolt fits your door. Bore is the diameter of the big hole through the face, 54 mm on most current hardware. Backset is how far the centre of that hole sits from the door's edge, 60 mm or 70 mm on nearly all residential doors. A replacement must match both to use the existing holes, and a fresh installation is cut to match the knob below, so knowing them ahead puts the right hardware on the van. Deadbolt Installation

It is yours. Some people keep a sound old cylinder as a spare or move a decent deadbolt to a shed or garage door, and the locksmith can rekey it to the house key for that purpose. Worn or damaged hardware is taken away for recycling if you prefer. Either way, the old keys should be gathered up and discarded so nobody confuses them with the new set. Lock Replacement & Upgrade

Almost certainly not. That pattern means the door has moved in its frame so the latch and bolt no longer meet the strike squarely. Solid wood doors in older houses swell in humid weather and settle on their hinges over the years. The service adjusts or shims the strike and tightens or packs the hinges so the bolt throws without lifting the door, and the lock itself is usually cleaned and lubricated at the same time. Vintage Mortise Lock Service

In most cases the lock and case are left intact, since manipulation, decoding and manufacturer reset paths all work the mechanism the way the original combination would. Drilling is kept for cases where the gentler routes are unavailable or exhausted, aimed at one small point the manufacturer marks as repairable, and patched before the visit ends; a skilled technician aims to leave the rest of the body, hinges and finish unaffected, though the outcome and any effect on the safe's rated protection level depends on its construction. Safe Opening & Combination Change

Delivery and the final move into position are part of the service, using equipment suited to the safe's actual weight rather than improvising with furniture dollies or straps meant for lighter loads. The route in is measured ahead of time so doorways, stairs, and tight turns are accounted for before the unit arrives, which avoids a surprise at the one hallway that turns out to be too narrow. Safe Installation & Servicing

Start with the doors that matter and the ones that are weakest, which are often not the same. Front doors usually carry the sturdiest hardware already; the side door by the driveway, the door from the garage and the basement walkout often carry the lightest locks and get the least attention. The assessment walks the whole perimeter with you so the upgrade goes where entry is most likely, and the remaining doors can join the same key later. High Security Locks

A keying chart is a plain list of every opening, the key group that operates it, the code stamped on those keys and the number issued. Months later it lets you answer exactly which doors a missing key opened, and it lets a locksmith add a new door to the system without changing anything else. Keep it with the key register, somewhere locked, with a copy off site. Commercial Rekeying

No. Some doors, such as a private office or a room with a single regular user, can reasonably stay on their own key outside the hierarchy if there is no real benefit to including them. The assessment is partly about deciding which doors belong in the system and which are simpler left alone, rather than assuming every lock has to join. Master Key System Design

Yes. Access levels can be set to change automatically by time of day or day of the week, so a credential that opens a door during a shift can be denied outside it without anyone having to remember to switch it off manually. This is set up once in the schedule and then runs on its own from that point forward. Access Control Installation

Yes, within what the door's rating allows. Exit devices and their trim come in a range of finishes to sit alongside other door hardware in the building, and outside trim in particular, being the visible part from a public side, can be chosen to match levers or pulls used elsewhere. A fire-rated opening narrows the finish choice somewhat, since the whole assembly has to stay within its listing. Panic & Exit Hardware

It is, and usually a simple one. A fob that lights up but the car ignores is diagnosed rather than assumed weak, since interference or fob damage can look the same. Once confirmed, many vehicles have a mechanical blade hidden in the fob and a driver's door cylinder for it, sometimes under a small cap, though some models use a different backup method. The locksmith opens that cylinder, fits a fresh battery, and shows you where a dead fob is held so a push-button car will still start. Car Lockout Service

Often, yes, for vehicles with a supported conventional key system: the car is opened, a blade is produced by decoding the door lock or retrieving the factory key code, and the immobilizer is reset so the missing keys are erased before new ones are stored. A key-card or phone-key vehicle, or one needing a dealer procedure, follows its own route instead, which is why the VIN is asked for on the first call. Car Key Replacement

The whole process depends on having a working key to read or trace from, so making the spare while that key still exists is simpler than the alternative of proving ownership without any key present and building access from scratch. A spare made now also means a future lost key is solved by reaching for the second one already tested and waiting, rather than starting the whole process from nothing. Spare Car Key Duplication

On many vehicles the key memory has to be reset before any new fob can be added, since nothing already accepted remains to authorize one; some vehicles instead accept an authenticated app or manufacturer service credential without a full reset. Where a reset is needed, it may take a security code specific to your vehicle or an approved access pathway built for exactly this situation. Once the reset completes, a full new set of fobs is registered and tested before the visit ends. Key Fob Programming
