Cabinet Lock Installation
A cabinet lock is a small piece of hardware, but the wrong one simply will not close. The cylinder has to match the thickness of the door, and the cam or bolt has to land behind the frame in exactly the right spot. This guide covers the main cabinet lock types, the measurements that decide the fit, your keying choices, and what a locksmith actually does during installation.

Most cabinet locks fall into a few families, and each one suits a different door style.
- Cam locks are the workhorse. A small cylinder sits in the door, and a flat metal arm called a cam rotates behind the frame to hold the door shut. Most use a wafer mechanism rather than pin tumblers, and better versions use tubular keys that are harder to copy casually.
- Plunger and ratchet locks are made for sliding glass doors. They clamp the two panels together or pin a panel to the track, so nothing is drilled into the glass itself.
- Drawer deadbolts throw a small bolt straight up into the cabinet body, which resists prying better than a thin cam.
- Surface-mounted locks screw onto the inside face of the door, a good choice when a door is too thin or brittle to drill cleanly.
The Measurements That Make or Break the Job
A cabinet lock that is the wrong size will either not close or not reach. Three measurements decide the fit.
- Door thickness. Cam lock cylinders come in set lengths, commonly 5/8 inch up to about 1-1/8 inch. The cylinder must pass through the door with enough thread left for the nut and the cam.
- Cam shape and length. A straight cam works on inset doors that sit flush with the frame. An offset cam bends back toward the frame for overlay doors that sit proud of it.
- Rotation. Cam locks turn 90 or 180 degrees, clockwise or counterclockwise, and the correct direction depends on which side of the cabinet the lock sits. The mounting hole is usually a double-D shape - a circle with two flat sides - so the lock body cannot spin in the door.
One Key for Everything, or Different Keys?
If you are locking more than one cabinet, decide how the keys should work before anything is installed.
- Keyed alike means every lock opens with the same key - the usual choice for a run of kitchen or office cabinets under one owner.
- Keyed different gives each cabinet its own key, which suits shared spaces like clinics and break rooms.
- Interchangeable core. Commercial casework can accept small format interchangeable core (SFIC) cam locks, so a facility can rekey a cabinet in seconds by swapping the core instead of removing the lock.
Stock hardware-store cam locks often ship in only a handful of factory keyings, so two strangers can end up holding the same key. A locksmith can supply locks with real keying options instead.
What a Locksmith Does During Installation
A clean installation starts with an assessment, not a drill. Door material and thickness get checked first, because particleboard and MDF chip easily and glass cannot be drilled at all. The work then runs in order: mark the lock position, bore the mounting hole with a sharp bit against a backing block to prevent blowout on the back face, fit and secure the cylinder, attach the correct cam, and test that the cam lands fully behind the frame or strike. Any keyed-alike plan is confirmed before the first hole is drilled, and you keep all the keys.

Frequently Asked Questions
Can a lock be added to a cabinet that never had one?
Yes, in most cases. A cam lock needs one round mounting hole, usually about 3/4 inch, plus a matching cam behind the door. The main risks are thin doors, brittle particleboard, and glass, which cannot be drilled. A locksmith measures door thickness first and may recommend a surface-mounted lock or a plunger lock instead if drilling would damage the door. Mention the cabinet material when you call so the right hardware comes to the job.
Can all my cabinets open with the same key?
Usually, yes. This is called keying alike, and it works when every lock shares the same key platform. The catch is that stock cam locks from different brands rarely share a keyway, so mixing hardware often makes keyed-alike impossible. If one key for everything matters to you, say so up front. A locksmith can supply a matched set of cam locks, or SFIC cores for commercial cabinets, so one key runs the whole row.
What kind of lock works on sliding glass cabinet doors?
Ratchet locks, often called showcase locks, are the standard answer. The lock slides onto the edge of the rear panel and a toothed bar clamps the two panels together, so no hole is drilled in the glass. Plunger-style locks that pin the door to the track are another option. Both types come keyed alike if you have several display cases. Never drill glass to fit a cam lock - it will crack or shatter.
