How to Choose a Drawer Lock: Size, Keys, and Fitting Checks

Start with the door or drawer thickness

A drawer lock is a small part, but it has to match the panel it will pass through. The first measurement to confirm is the thickness of the drawer front, cabinet door, or metal panel. The cylinder must be long enough to pass through the panel and hold the cam securely at the back, but not so long that it sticks out awkwardly or leaves the cam sitting too far away from the locking point.

The safest buying step is simple: bring the old lock, a clear photo, or the panel thickness measurement. For replacement jobs, the old lock is usually the fastest reference because it shows the cylinder length, cam shape, key type, and fixing style together.

Match the lock type to the furniture

Most drawer and cabinet locks used in furniture are cam-style locks. When the key turns, a flat metal cam rotates behind the drawer or cabinet frame and stops the front from opening. Similar lock styles can be used on drawers, swing cabinet doors, cupboards, and some light metal panels, but the cam length and bend must suit the fitting point.

Use a drawer lock for desks, cabinets, cupboards, counters, and furniture drawers where a basic key lock is needed. For main doors, shutters, gates, or high-risk storage, use a proper door lock, hasp and padlock, or heavier security hardware instead.

Check key quantity and key control

Small drawer locks are often sold with two keys, but packing varies by brand and stock. If several drawers must open with the same key, ask before buying because keyed-alike sets are not the same as ordinary mixed-key stock. If each drawer should have a different key, mention that too so the shop does not accidentally quote a matching-key batch.

For office desks, shop counters, or shared storage, also ask whether spare keys are available. Some low-cost locks are easy to replace but not easy to duplicate later, so it is better to decide the key requirement before a full batch is fitted.

Confirm size, code, and packing before bulk orders

MJ Trader currently has drawer lock products such as KHAS Drawer Lock with 2 Keys, SAK Drawer Lock, and Asian Elephant Drawer Lock listed in the catalogue. Sizes, product codes, box quantities, and carton quantities should still be confirmed at the time of quote because packing can vary between brands and batches.

For a carpenter or contractor, the best quote request includes:

• Quantity needed
• Drawer or cabinet material
• Panel thickness if known
• Whether same-key or different-key locks are needed
• A photo of the old lock or fitting location
• Whether you need pieces, boxes, or cartons

Common buying mistakes

• Buying by photo only without checking cylinder length
• Assuming every drawer lock comes with the same number of keys
• Mixing cupboard-door locks and drawer-front locks without checking the cam position
• Ordering a full carton before testing one piece on the actual furniture
• Ignoring the old lock code when it is visible on the key or lock body

Quick recommendation

For one replacement, bring the old lock or a photo from the front and back. For a full furniture job, test one sample first, then confirm the final quantity once the fit is correct. That keeps the order practical and avoids buying a carton of locks that almost fit but do not close properly.
