Locksmith FAQ

Lockout Services

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. Home Lockout Service

Do you work with our alarm company and access-control provider?

Yes, and it makes the visit smoother. The alarm station is told an entry is expected and the authorised person handles the disarm and password. For access control, the provider can often confirm the controller's status, unlock a magnetic lock remotely, or re-enrol fobs once you are inside, while the locksmith handles the mechanical side and the override cylinder. Nobody's wiring is cut; each party does the part it is set up to do. Business Lockout Service

Can you extract a key from a padlock, mailbox or filing cabinet?

Yes. Small cylinders in padlocks, mailboxes, desk drawers, filing cabinets and cam locks on lockers hold a fragment the same way a door does, and the same slim hooks and spirals fit them. Their keyways are narrower, so it is finer work. Where a padlock is not worth saving, the locksmith will say so and offer a cut-off and a new padlock keyed to your preference instead. Broken Key Extraction

Will the repair be visible from outside?

Mostly not. A boxed strike sits flush in the jamb, long screws hide behind hinge and strike plates, and a repaired jamb is filled and dressed so paint or stain covers it. A wrap-around door edge reinforcer is the one part that shows, as a slim steel band at the lock, and it can be finished to match the hardware. New deadbolts are matched to the trim on your other doors where you want them to blend in. Break-In Damage Lock Repair

Change or Rekey Locks

My house is older and has a mortise lock. Can that be rekeyed?

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

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. Deadbolt Installation

My door has glass beside it. Should I fit a deadbolt keyed on both sides?

A keyed interior cylinder means finding a key to get out, which is not what you want on a door people use every day. The steadier answer for a door with glass is a single-cylinder deadbolt with a thumb-turn, combined with a reinforced strike, a longer bolt and a security film or laminated glass in the sidelight. Lock Replacement & Upgrade

The key turns all the way round but the bolt stays put. What is wrong?

On a cylinder mortise lock this points to the cylinder rather than the case. The set screw that holds the cylinder in the door has loosened or stripped so the whole cylinder rotates, or the cam on the back of the cylinder has worn or is the wrong shape and no longer catches the bolt lever. Both are fixed by resetting or replacing the cylinder and its set screw, and the case itself is usually fine. Vintage Mortise Lock Service

High Security Locks

Can the same visit both open the safe and service it?

Yes. Once the safe is open, the lock is inspected for wear, corrosion or damage, repaired or replaced if needed, and reset to a new combination in the same visit. Any bolt work or handle issue found along the way is addressed at the same time rather than requiring a separate appointment. Safe Opening & Combination Change

What is the difference between a mechanical dial lock and an electronic keypad?

A mechanical dial has no battery and is set by hand to a private combination, turning through a sequence to release the bolt; it never runs out of power but takes a little practice to open. An electronic keypad accepts a numeric code and can support several separate codes for different people, but it depends on a battery that eventually needs replacing. Many owners choose based on how many people need access rather than one being simply superior to the other. Safe Installation & Servicing

Should I upgrade the front door only, or every door?

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

Commercial Locks

We are a landlord with a tenant leaving. When should the unit be rekeyed?

Between tenants is the ideal moment: the departing tenant has handed back their keys, the new one has not yet received any, and the unit is empty for the work. The incoming tenant then starts on keys nobody else has held, and the landlord's own master or emergency key is set up at the same time. Where a lease has ended in dispute, the locksmith asks to see the paperwork before changing locks on a unit that still holds a tenant's goods. Commercial Rekeying

Can a master key system be expanded later without redesigning it?

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

Will this work with our existing alarm or camera system?

In most cases, yes. An access control installation can be planned to share information with an existing alarm panel, so an arm-or-disarm event lines up with whoever unlocked the door, and with a camera system, so a recorded clip can be matched to a specific credential rather than only a timestamp. The exact integration depends on what the existing alarm and camera equipment support. Access Control Installation

What should I have ready before the visit?

Knowing the intended use of the room, roughly how many people it holds, whether any doors are already fire-rated, and whether any of them are part of a pair helps the locksmith bring the right devices. If a fire inspector or building official has already given a note about the opening, having that note or its reference number on hand keeps the visit focused on what was actually flagged. Panic & Exit Hardware

Car Keys

My fob is not working. Is that a lockout?

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

How many keys should a car have?

Two working keys is the sensible minimum, and it is what most vehicles left the factory with. One lives on your ring; the other lives somewhere safe away from the car. With two, any future key work is an add-a-key job rather than a reset from nothing. Households that share a vehicle, or owners with a remote starter on one fob and a plain key for the valet, sometimes prefer three. Car Key Replacement

What identification do I need to bring for a vehicle that isn't mine, like a company car?

Bring whatever document shows your connection to the vehicle in that situation: a company letter or fleet record for a workplace vehicle, a lease agreement for a rented one, or a note from the registered owner for a family member's car. The locksmith is confirming that the person asking for a key is entitled to hold one, which protects the vehicle's owner as much as it protects you. Spare Car Key Duplication

Can you tell me which fob to buy before you arrive?

Often, yes, once the vehicle's identification number, model year and trim are known, since those details narrow down which fob part is actually compatible. Buying the wrong part number is a common reason a programming attempt goes nowhere, so confirming compatibility before ordering saves a returned part and a second visit. Key Fob Programming
