High Security Locks

Open 24/7

After the attempted break-in the police officer pointed at your door and said the strike plate was held by two short screws. Nobody got in, but you have looked at that door differently every evening since.

Request a visit

In plain words

This service suits anyone who wants to stop wondering. Homeowners who have inherited unknown keys with a house, landlords who want one controlled key system across units, and businesses protecting stock, records or medication all ask for it. The locksmith explains the choices in plain terms, from a graded deadbolt with a patented cylinder up to laboratory-rated cylinders and heavy commercial lock bodies, and helps you decide which doors deserve which level. Then the work is done cleanly, every key is tested in every lock, and you leave with the documents that let you control future keys.

The call: You jiggle the key a little and the old deadbolt opens even when the cut does not look quite right. If your worn key can do that, you wonder what a stranger with the right tools could do.

How the visit goes

Scene 1
What the door is protecting
The assessment starts with a question rather than a tape measure: what is behind this door, and what has made you think about it now? A front door on a family home, a stockroom with prescription drugs and a server closet in an office carry different risks and deserve different levels of hardware. The locksmith also asks who has keys today and how sure you are of that count. Those answers decide whether the right answer is a graded deadbolt with a controlled key, a laboratory-rated cylinder in a heavy lock body, or a small keyed system across several doors. Spending goes where the risk actually sits.
Scene 2
Fitting a heavier deadbolt
When the existing deadbolt is light or worn, the locksmith fits a graded deadbolt through the same bore where possible. The bolt throws a full inch and carries a hardened steel pin that turns under a saw blade, and the housing keeps part of the bolt supported against a kick. The latch is set in the edge bore with the correct backset, the exterior housing and interior thumb-turn are joined through the door with the long screws, and the final tightening is done by hand so nothing strips. The bolt is then thrown with the door open and closed to confirm it extends completely.
Scene 3
Fewer keys, clearer purpose
Many customers finish the visit carrying fewer keys than they started with. Exterior doors keyed alike mean one key for the house; a small master system means a manager carries one key for the whole premises. Each key has a known job. The locksmith explains which key opens which door and leaves that in writing, so the tenth person to ask does not get a shrug. Should you add a door later, a gate, a garage entry or a new office, it can join the same system so you keep the single-key convenience without opening a fresh keyway.

What shapes the quoteAshburnham Lock Experts

Commercial lock bodies: Heavy-duty deadbolts, mortise locks, narrow-stile deadlocks and cylinder guards for storefront and warehouse doors are heavier hardware than residential deadbolts and priced as such.
Master keying: Arranging staff keys, area keys and a manager key on one system takes bench time to plan and pin, and the more levels you want, the more careful that planning is.
Number of doors: Each door gets its own cylinder or lock, strike work and testing. Several doors on one keyway share the setup cost of the key system but add hardware and time per opening.

Questions we hear most

What is the difference between restricted and patented keys?

A restricted keyway is one the manufacturer supplies to a limited set of dealers, so blanks are harder to obtain but not legally protected. A patented key design is protected by a patent for a fixed term, and making or selling the blank without permission is unlawful during that time. Patented systems give the firmer control; restricted ones give a useful step up. The locksmith explains which your chosen line uses and when any patent expires.

What should I do when a controlled key is lost?

Tell your locksmith so the register is updated, then decide together what the loss means. If the key was lost with nothing identifying your address, the practical risk is low and many people simply strike it off. If it went missing with identification or from a known person, the affected cylinders can be repinned so that key stops working while the rest of the system continues. Because the keyway is controlled, you know that no further copies exist.

What information helps before the visit?

A photo of each door's lock from inside and outside, the type of door, whether there is glass nearby and roughly how many keys are in circulation. For a business, a sketch of the doors and who needs to reach each area saves a great deal of time. Mention any door that sticks, has been forced or has a closer or push bar on it. With that, the locksmith arrives with the right formats and a plan to discuss.
