About LCN
Among the most durable commercial door closers made, and extremely common on GTA commercial and institutional entrances. We adjust, rebuild and replace LCN closers across the surface-mounted and concealed ranges, including the heavy-duty units on high-traffic entrances. An LCN closer that is not leaking is usually adjustable back into spec rather than needing replacement, and that is the first thing we check.
We are an independent locksmith and door hardware contractor. We service, repair and install LCN products and source parts through trade supply. Product names and trade marks referenced here belong to their respective owners and no affiliation or authorised-dealer relationship is implied unless stated.

Do you service LCN hardware?
Yes. Among the most durable commercial door closers made, and extremely common on GTA commercial and institutional entrances. We adjust, rebuild and replace LCN closers across the surface-mounted and concealed ranges, including the heavy-duty units on high-traffic entrances. An LCN closer that is not leaking is usually adjustable back into spec rather than needing replacement, and that is the first thing we check.
Is LCN worth specifying?
It depends on the door and what it is protecting, and we would rather give you a straight answer than a sales one. It is well-regarded commercial hardware and widely specified across the GTA. What matters more than the badge is that the grade matches the actual cycle count of the door — a grade-2 unit on a high-traffic entrance fails early regardless of who made it.
Can LCN locks be rekeyed?
In nearly all cases, yes — rekeying re-pins the cylinder you already own and is far cheaper than replacement. If the locks share a keyway they can also be keyed alike so one key covers several doors.
