How Do You Lock a File Cabinet That Has No Lock?
To lock a file cabinet with no lock, fit an external locking bar made for its drawer count and frame, then secure the bar with a compatible padlock. If you don't want to drill into the cabinet, use a locked room or a cabinet designed with a built-in lock.

To lock a file cabinet with no lock, attach an external locking bar that matches the cabinet's drawer count and frame, then secure it with a compatible padlock. If you don't want to drill into the cabinet, keep it in a locked room or switch to one with a built-in lock.
First check whether the cabinet is metal, how many drawers it has, and whether its frame gives you a suitable mounting surface. A locking bar can be a practical retrofit, but it doesn't make every cabinet secure against determined entry.
How do you lock a file cabinet with no lock?
Use an external locking bar made for the cabinet's drawer count, mounted as its instructions require. The bar sits across the drawer fronts and blocks them from opening when locked.
Before buying, check the cabinet frame, the direction the bar can mount, and whether you need to supply a padlock. Some bars require drilling and screws.
If you can't drill into the cabinet, use a different storage plan.
Guardianite's 4-drawer bar is made from 16-gauge steel with a beige powder coat. It mounts to a 1/2 in frame and can be reversed for left- or right-side mounting.
It includes a cobalt drill bit. The padlock is not included.
Measure the frame before you choose it. The bar's dimensions are 46 x 1.5 x 0.7 in.
What should you check before installing a locking bar?
Confirm the bar fits the drawer count and mounting area before drilling. Then read its instructions and check that the bar can close across every drawer without hitting handles or other hardware.
A 2-drawer bar is shorter than a 4-drawer bar, so don't choose by appearance alone. The Guardianite 2-drawer bar is made from 16-gauge steel with a gray powder coat and mounts to a 1/2 in frame.
It can be reversed for left- or right-side mounting, and a cobalt drill bit is included.
This bar uses a separate padlock, which is not included. Measure the cabinet and check the mounting instructions before making holes.
For a 4-drawer option, the ABUS bar is made from 16-gauge steel and can be mounted on either side by reversing its knob. Mounting screws are included.
Use a compatible padlock to secure it.
The ABUS bar is designed to restrict access to filing cabinet drawers. Confirm its dimensions and mounting approach suit your cabinet before installing it.
How do you install an external locking bar?
Follow the bar's instructions and position it so it covers the drawers without obstructing normal use when open. If installation requires drilling, take care to avoid damaging drawer parts or anything inside the cabinet.
The Guardianite bars mount to the 1/2 in frame around a metal cabinet. Their spring-loaded hinges hold the bars open when unprotected, so the bars shouldn't interfere with opening or closing drawers in that position.
Before drilling, check the bar's orientation and mark its mounting points as directed. If you're not comfortable drilling into the cabinet, stop and choose another way to control access.
Once mounted, open and close each drawer with the bar unprotected. Then close the bar and check that it sits across the fronts as intended.
Fit the padlock and confirm it secures the bar before storing private papers.
What if you don't want to drill into the cabinet?
Use a locked room or a cabinet with a built-in lock if you can't drill into the existing cabinet. A cable or strap may discourage casual opening, but it can leave gaps and should not be treated as equivalent to a fitted lock.
A replacement cabinet is a clearer choice when you need a built-in lock. The DEVAISE 2-drawer cabinet has a key lock that secures both drawers at once, and it comes with 2 keys.
The cabinet is fully assembled except for the casters.
It has five wheels, including a front central caster. If you choose a wheeled cabinet, position it where you can control access and keep it stable.

Is a locking bar right for sensitive documents?
A locking bar can restrict access to drawers, but its protection depends on a correct fit, sound mounting, and a suitable padlock. Consider who can reach the cabinet and whether the room itself needs to be secured.
For sensitive records, follow your workplace or organization's storage rules. A cabinet lock may help control access, but it doesn't replace access procedures or other safeguards.
If your cabinet already has a lock that won't turn, see how to fix a file cabinet lock. If you need a cabinet with a built-in lock, compare options in our guide to file cabinets with locks.
How do you choose the right option?
Choose a locking bar when its drawer count and mounting fit your cabinet; choose a built-in lock when you want a cabinet designed for locking. If drilling isn't suitable, control access to the room instead.
For a 2-drawer metal cabinet, consider the Guardianite 2-drawer bar after checking its frame requirements. For 4 drawers, compare the Guardianite and ABUS bars, including their mounting instructions and padlock needs.
Before moving a cabinet to a more secure spot, review how to move a heavy file cabinet. Then choose a locking method you can install correctly and use consistently.
Frequently asked questions
Can you lock a file cabinet that has no lock?
Yes. An external locking bar can block access to the drawers when secured with a compatible padlock.
Check the bar's drawer count and mounting requirements against your cabinet before buying.
For a no-drill option, store private papers in a locked room or use a cabinet with a built-in lock.
Do file cabinet locking bars need a padlock?
Many external bars use a separate padlock, which may not be included. Check what comes with the bar and choose a padlock that fits its locking point.
Keep the key or combination separate from the papers you're securing, and check that the bar moves freely before using it.
Can I install a file cabinet lock without drilling?
Some external bars require screws and drilling into the cabinet frame, so they aren't no-drill solutions. If you can't make holes, consider keeping the cabinet in a locked room or replacing it with a cabinet that has a built-in lock.
A strap or cable can deter casual access but may not secure every drawer.
Is a locking bar as secure as a built-in file cabinet lock?
A locking bar blocks drawer access from outside, but it isn't the same as a cabinet built with a lock. The result depends on the bar's fit, mounting, padlock, and cabinet construction.
For sensitive records, also limit who can access the room and follow your organization's storage rules.
