Lockout Services
Will opening the door damage my lock?
In most residential lockouts the lock is untouched. Picking, decoding and latch tools operate the mechanism the same way your key does, so there is nothing to repair afterwards. A drill only appears when a cylinder is seized, plugged by a snapped key or engineered against picking, and you hear about that before it starts. Should it come to that, replacement hardware goes on before the locksmith leaves so you lock up normally that evening. Home Lockout Service
What is an interchangeable core, and how do I know if we have one?
An interchangeable core is a small, self-contained cylinder that slides out of the lock with a special control key and drops back in on a new combination. Look at the keyway: a figure-eight shaped face on a lever or mortise housing is the usual sign. Buildings choose them because a lost key or a staff change is handled by swapping the core rather than taking the lock apart, and a locksmith can carry cores pinned to your system.

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. Broken Key Extraction
How do I check that the repair is holding over the following months?
Once a month for the first season, throw the deadbolt with the door closed and feel for drag or a stop short of full extension, and press on the strike and hinge screws with a screwdriver to confirm they are snug. Repeat at each change of season, since wood moves with humidity. A door that starts needing a shoulder, or a bolt that catches on the strike lip, wants a small adjustment early rather than a repeat of the original problem. Break-In Damage Lock Repair

Change or Rekey Locks
My locks are different brands. Is that a problem?
Not a problem, just a detail to plan around. What matters is the keyway, meaning the profile of the slot the key fits, rather than the name on the lock. Different makers sometimes share a profile and sometimes do not. Where two cylinders cannot accept the same key, one is exchanged for a compatible cylinder in the same finish and pinned to match. From the outside the door looks the same and from your pocket it is one key. Lock Rekeying
Does the finish of the deadbolt matter beyond looks?
It does on an exposed door. Winter salt spray, summer sun and humid air all work on the outside trim, and residential deadbolts carry a finish grade that reflects how well the coating resists them. A lifetime or PVD-style finish stays bright longer on a south-facing or roadside door, while a sheltered porch door can carry any finish you like. Matching the knob or lever below is mostly a matter of taste. Deadbolt Installation
Which finishes stand up to salt and winter?
Finish is one of the three categories on the residential hardware label, and it covers exposure to sun, humidity, salt and skin oils. In practice, PVD brass, satin nickel and stainless finishes tolerate a salted driveway well, powder-coated black holds up when it is not chipped, and traditional lacquered brass tends to bloom green where salt reaches it. A storm door or a small overhang helps any finish, and wiping salt off in a thaw helps more. Lock Replacement & Upgrade
Which parts usually need replacing?
Springs, first and foremost: the latch spring, the hub spring that returns the knob, and the small springs on the deadbolt levers. After that, the spindle and knob set screws, a hub whose square has worn round, a worn deadbolt lever or follower, and on later locks the cylinder set screw or the cylinder itself. Bolts, cases and trim are almost always kept, cleaned and refitted rather than replaced. Vintage Mortise Lock Service

High Security Locks
What should I have ready before the visit?
The safe's brand and model if you know them, whether the lock is a dial, a keypad or a key, roughly how old the safe is, and how the combination was lost or forgotten. Mention whether the safe holds anything with its own handling needs, such as firearms or business records, and how many people should have the new code afterward. Safe Opening & Combination Change
What does a typical installation or servicing visit involve?
The visit opens with a look at what the safe needs to protect and where it will sit, moves into positioning and anchoring for a new unit or bolt-work and lock testing for an existing one, and ends with the lock cycled several times and a combination or code set that only the owner knows. The exact order shifts depending on whether the job is a new installation or ongoing servicing. Safe Installation & Servicing
Do high security locks need special maintenance?
Only light care. Use the dry lubricant the locksmith recommends once or twice a year, never oil, which gathers grit around the finger pins and sidebar. Keep the keyway free of debris and insert the key fully before turning. In winter, warm a resisting key in your hand or use a de-icer rather than forcing it. Check hinge and strike screws each season so the door stays aligned. Treated this way the cylinder lasts for decades. High Security Locks

Commercial Locks
What happens with our fire exit doors and panic bars?
The outside cylinder on an exit door controls entry only, and it can be rekeyed like any other. The inside stays as it must: one push or one turn, no key, no special knowledge, on the exit door itself and on any door on the way to it. A locksmith will not add a keyed device to the inside of an exit, and will point out one if it already exists. Commercial Rekeying
Can different lock brands be mixed in one master key system?
Sometimes, but it depends on the keyway and pinning platform each brand uses; some are compatible with one another and some are not. Where a mix already exists on a property, the assessment identifies which cylinders can be brought into a single hierarchy and which need replacing with a matching platform so every level pins correctly across the whole set of doors. Master Key System Design
What's the difference between an electric strike and a magnetic lock?
An electric strike fits into the existing door frame and works with the door's own latch or bolt, releasing it briefly for a valid credential while otherwise behaving like an ordinary strike plate. A magnetic lock instead clamps the door shut with an electromagnet mounted at the head of the frame, and it is always installed with a request-to-exit device so someone leaving is never held up looking for a way out. Access Control Installation
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. Panic & Exit Hardware

Car Keys
The lock is frozen and the door will not budge. What will you do?
Ice is handled gently. Lock de-icer and mild warmth free the cylinder so it turns without force, and a door stuck to its seal is released by pressing along the edge to crack the ice rather than pulling the handle, which can tear the rubber. Hot water is never used because it refreezes and can crack glass. Afterwards the cylinder is lubricated with whatever product the vehicle maker specifies and the seals are treated with silicone. Car Lockout Service
Do you use original manufacturer fobs or aftermarket ones?
Both exist, and the locksmith will say which is proposed for your car. Original parts match the vehicle exactly and are the safer choice for the newest systems and for features like remote start or phone pairing. Well-made aftermarket keys and fobs are widely used on common models and suit spares and older vehicles. What matters in every case is the correct frequency, part number and chip type, which the VIN confirms. 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
How do I stop all my fobs from wearing out around the same time?
Replacing coin-cell batteries as soon as a fob's range starts to feel shorter, rather than waiting for it to go completely dark, is the simplest habit. Keeping fobs off a keyring crowded with heavy metal keys reduces wear on the case and buttons as well. Since fobs from the same purchase batch often age together, a fading one is worth treating as an early warning for the others. Key Fob Programming
