Best Keyed Alike Cylinders for a Household
Keyed alike cylinders replace mismatched cabinet and drawer locks with one family of locks that opens on a single key, and this short roundup covers five sets that do exactly that. The picks split along pack size and cylinder length: small two- and four-packs for a few drawers or a mailbox, three- and five-packs for a kitchen or a workshop, and a six-pack with longer cylinders for deeper panels. Renters locking a few cabinets, homeowners matching a whole room of storage, and RV or tool-box owners replacing tired locks all have a reasonable option here. The overview table below lines up the differences before the individual write-ups.

Zinc Alloy Office Desk Drawer Locks XIEHE 138 Furniture Wardrobe Cylinder Cam Wooden File Cabinet Keyed Alike Locker for Cabinet Door Cupboard Drawer Household Mailbox Letter Box Packs with Keys (4)
Material: Zinc alloy
Type: Cylinder cam lock
Pack Size: 4
Keys: Included
Intended Use: Desk drawers, wardrobes, wooden file cabinets, cupboards, mailboxes
This four-pack is the practical starting point for a household that wants a handful of mismatched locks replaced without buying a large set. The zinc alloy bodies and cam design suit wood furniture — desk drawers, wardrobe doors, file cabinets and cupboards — where the panel is thin and the lock only needs to stop casual access. All four cylinders are keyed alike, so one key covers every drawer in the set. The pack also fits letter boxes and small mailboxes, which makes it a flexible starter kit rather than a single-purpose purchase.
The pick earns its place on pack size and simplicity: four locks is enough to finish a desk and a file cabinet, but not so many that the box sits half-used in a drawer. It suits renters and homeowners who are matching a small run of furniture and do not want to overbuy. The caution is the one that follows inexpensive multi-packs — the keys and cams are built to a price, so heavy daily use on a main-entry cabinet will wear faster than a premium cylinder, and the wood-screw mounting is aimed at timber panels rather than metal doors.
Trade-off: A budget four-pack that covers small furniture well, but the hardware is light-duty and better suited to occasional access than a high-traffic cabinet.
Cabinet Cam Locks Keyed Alike, 5/8” Cylinder Cam Locks for Tool Box RV Compartment Mailbox Vending Machine Drawer File Cabinet, Fits 3/8” Max Panel Thickness, Chrome Finish with 3 Cams and 2 Keys
Material: Chrome-finished body
Type: 5/8" cylinder cam lock
Panel Thickness: Fits up to 3/8"
Included Cams: 3
Included Keys: 2
Intended Use: Tool boxes, RV compartments, mailboxes, vending machines, drawers, file cabinets
This is the most flexible single lock in the group, and the three included cams are the reason. A cam is the rotating arm that catches the frame, and different compartments need different arm offsets and lengths — a vending machine door, an RV hatch and a wooden drawer rarely want the same one. Buyers get three to experiment with, plus two keys, and the chrome finish holds up better than plain zinc against weather and handling. The 5/8" cylinder fits panels up to 3/8" thick, which covers most metal and thin-wood applications.
It suits the buyer with a mixed list: a tool box, a compartment on a camper, a mailbox and a filing cabinet that all need to answer to one key. The chrome body and multi-cam kit put it a step above the plain budget packs in finish and versatility. The caution is fit — a 5/8" cylinder with a 3/8" panel limit will not reach through a thick wooden door or a double-walled panel, so buyers with chunky cabinets should measure before committing.
Trade-off: Versatile thanks to the three cams and better finish, but the short cylinder rules out thick panels and double-walled doors.
Cylinnda Cabinet Locks (3 Pack, Zinc Alloy), Keyed Alike Cam Lock for Tool Box, RV Storage, Mailbox, 5/8"
Material: Zinc alloy
Type: 5/8" cylinder cam lock
Pack Size: 3
Keys: Included
Intended Use: Tool boxes, RV storage, mailboxes, cabinets
A three-pack is an odd size on paper and a sensible one in practice: it covers a mailbox, a tool box and one RV storage bay, or three drawers in a single cabinet, without leaving spares. The zinc alloy bodies and 5/8" cylinders follow the standard cam-lock pattern, so installation is the familiar drill-and-mount job. All three are keyed alike, and the set is aimed squarely at the outdoor and semi-outdoor uses in its name — tool boxes, RV compartments and mailboxes — where a simple, serviceable lock is the point.
It earns its place as the middle option between the tiny two-pack and the larger multi-packs, and it suits a household that has three specific things to lock rather than a whole room. The zinc alloy is honest for the price but not weatherproof in the way a stainless body would be, so a mailbox or an exposed RV hatch will show finish wear over seasons of rain. Buyers in a wet climate should expect to keep the keyway clean and lubricated.
Trade-off: A tidy three-pack for a few outdoor compartments, but the zinc finish will weather on exposed mailboxes and hatches.
Jayseon 6 Pack Cam Locks Keyed Alike, 1-1/8 Inch Cylinder Cabinet Lock with Keys, Zinc Alloy Cabinet Locks for Drawer Cabinets Mailbox RV Storage Drawers Lock
Material: Zinc alloy
Type: 1-1/8" cylinder cam lock
Pack Size: 6
Keys: Included
Intended Use: Drawer cabinets, mailboxes, RV storage drawers
The long cylinder is what separates this set from the rest. At 1-1/8", it reaches through thicker panels than the 5/8" locks, which makes it the right choice for solid-wood drawer fronts, built-in cabinets and doubled-up RV panels where a short cylinder would not seat properly. Six locks keyed alike turn a whole run of kitchen or workshop drawers into one-key storage, and the zinc alloy bodies keep the set affordable at that volume.
This is the pick for the household doing a full matching job — every drawer in a kitchen island, a bank of garage cabinets, plus a mailbox — where buying six separately would cost more and leave keys unmatched. The caution is that the longer body is less forgiving of thin panels: on a flimsy drawer bottom or a hollow-core door, the extra cylinder length has nothing solid to grip, and the lock may sit proud or feel loose. It rewards buyers who measure panel thickness first.
Trade-off: The best value for matching many drawers at once, but the long cylinder needs a genuinely thick panel to seat well.
2Pcs Cabinet Cam Lock Keyed Alike Tool Box Locks 5/8" Cylinder for Truck Pickup Tool Box Vending Machine Drawer Tool box Mailbox ATM Locks Replacement
Material: Metal body
Type: 5/8" cylinder cam lock
Pack Size: 2
Keys: Included
Intended Use: Truck and pickup tool boxes, vending machines, drawers, mailboxes, ATM replacement
This two-pack is a replacement kit, not a matching project. The 5/8" cylinders follow the common cam-lock pattern used on pickup tool boxes, vending machine doors and ATM panels, so the pair works as a direct swap when an existing lock has failed or the key has gone missing. Both cylinders are keyed alike, which means a truck box and a second compartment can share one key, and the metal bodies are built for the kind of duty those applications demand.
It suits the buyer who has one or two specific locks to replace and does not need a drawer full of spares — the pickup owner, the route operator, the household patching a single mailbox. Two keys and two locks is a clean, low-waste purchase. The caution is scope: with only two units, this set cannot match a kitchen or a workshop, and the emphasis on replacement means buyers should confirm the mounting hole and cam style of the old lock before ordering, since a near-match will not drop in.
Trade-off: A focused replacement pair for one or two locks, but too small to match a room and dependent on the old lock’s mounting pattern.
Before You Buy
- Material: Zinc alloy is the norm at this price and handles indoor use well; chrome or stainless finishes hold up better on mailboxes, RV hatches and other exposed locks.
- Cylinder length: 5/8" cylinders suit thin metal and wood panels up to about 3/8"; 1-1/8" cylinders are needed for thick drawer fronts and doubled panels.
- Panel thickness: Measure the door or drawer front before ordering — a cylinder that is too short will not seat, and one that is too long will sit proud.
- Mounting pattern: Replacement locks must match the existing hole size and cam style; check the old lock before buying rather than after.
- Pack size: Count the locks needed first — a two-pack for a repair, a four- or six-pack for matching a run of drawers or a whole room.
- Included accessories: Cam count and key count vary by set; extra cams allow different arm offsets, and a second key is useful for a household with more than one user.
- Care: Keep the keyway clean and lightly lubricated, especially on outdoor locks, and avoid forcing a stiff key in cold weather.
Frequently Asked Questions
- What does "keyed alike" mean? Every lock in the set opens with the same key, so one key covers all the cabinets, drawers and boxes in the household rather than a separate key for each.
- Can keyed alike cylinders be rekeyed to match existing locks? Generally no — these are fixed-key sets, so matching an existing key means buying a set that already shares it rather than adapting one.
- Which cylinder length is right for a wooden drawer? A 5/8" cylinder suits thin panels and metal boxes, while a 1-1/8" cylinder is the safer choice for solid-wood drawer fronts and thicker built-ins.
- Are these locks suitable for outdoor mailboxes? They can be, but zinc alloy will weather; a chrome or stainless finish and regular lubrication extend life on exposed boxes.
- How many locks does a typical household need? Count the drawers, cabinets, mailbox and any tool or RV boxes first — most homes land between three and six locks for a full matching job.
- Do the sets include keys and cams? Yes, each set ships with keys, and some include multiple cams for different mounting offsets; check the listing for the exact count.
Bottom Line
For most households, the Cabinet Cam Locks Keyed Alike 5/8" set is the safest single buy: the three included cams and chrome finish make it the most adaptable lock here for mixed compartments, and two keys cover a small household. Buyers matching a whole run of thick drawers should step up to the Jayseon six-pack instead, and anyone replacing one or two locks can save money with the two-pack. Whichever set fits the job, confirm panel thickness and pack size first — then order with confidence.
