By the end of this guide, you’ll be able to make an informed decision on what a good locks to put on metal filing cabinets based on your specific requirements. Let’s get started!
Basic Key Locks
Key locks are the most common and economical choice for securing metal filing cabinets. Here are some of the key features to look for in a basic key lock:
Cylinder Quality
The cylinder is the part of the lock where you insert the key. Higher quality cylinders tend to be more pick and drill resistant. Look for cylinders made from hardened steel or stainless steel for better security.
Number of Pins
More pins in the cylinder make the lock harder to pick and decode. Go for at least 5 pins or more for adequate security.
Key Control
Opt for a lock system that allows you to remove the core and rekey it yourself. This lets you regain key control if a copy falls in the wrong hands.
Multiple Users
Consider a master key system if multiple people need access. This provides different keys for each user while the master key can open all locks.
Lock Alignment
Make sure the lock easily aligns with the default cabinet preparation. Misalignment can cause locking problems.
Emergency Lock Release
Many key locks have a release hole on the rear to open locked cabinets without a key. This is useful if you lose your keys but lowers security.
Overall, basic key locks provide a cost-effective deterrent for casual theft. But they can be picked or bypassed by determined intruders. For highly sensitive documents, you may need more advanced locks.
Electronic and Biometric Locks
Electronic and biometric locks offer stronger security for your confidential filing cabinet contents. Here are some top options to consider:
Keypad Locks
These allow access by entering a code on an electronic keypad. Benefits include easy reprogramming if codes are compromised. However, visibility of the keypad makes shoulder surfing a risk.
RFID Card Locks
RFID or proximity card locks unlock when presented with the right RFID card or fob. They eliminate picking and copying risks but anyone with the card can gain entry.
Biometric Finger Print Locks
For top security, biometric locks that rely on fingerprint recognition are hard to beat. Only authorized fingerprints can release the lock. But they are pricier than other electronic locks.
Bluetooth/WiFi Locks
Connected locks allow you to control cabinet access from your smartphone, even when away from the office. But they require power and WiFi connectivity.
Electronic locks are more convenient for shared offices. But like any electronic gadget, they can malfunction and may require battery replacement. Make sure your lock has a mechanical override key in case of power failure.
Other Lock Enhancements
Aside from the core locking mechanism, also consider these features for better security and convenience:
Locking Drawers
To restrict access to certain drawers, opt for individual locks on each drawer. Some filing cabinets have this built-in while others need retrofitted locks.
Lock Bars
A lock bar or lock rail connects the locks on each drawer. This ensures all drawers lock simultaneously when you turn the key or press the electronic lock.
Security Cables
Attaching a steel security cable to the cabinet provides an additional layer of protection. This deters burglars from stealing the entire cabinet.
Anti-Pry Construction
See if the cabinet has elements like concealed hinges and welded joints that prevent prying open. Some locks have boltwork that engages on all sides when locked.
Lock Lubrication
Frequently lubricate key and combination locks with powdered graphite to ensure smooth operation and prevent seizing up.
Getting locks with one or more of these extra features improves the security of your filing cabinet contents for sensitive documents.
Lock Options for Fireproof Cabinets
Fireproof filing cabinets require locks that can withstand high temperatures in a fire. Here are suitable options for fireproof cabinets:
Thermally Actuated Locks
These advanced mechanical locks automatically engage if the temperature reaches a certain threshold, sealing the drawers shut. Popular for fireproof cabinets.
Fire Rated Deadbolts
Look for high temperature rated deadbolt locks certified for fire endurance. Ensure at least a UL 72 class rating.
Frangible Lock Cylinders
Frangible cylinders are designed to break away if the cabinet burns, preventing the security container from cracking due to heat expansion.
The lock hardware should have at least a UL 10C rating for fire exposure if used on fire resistant cabinets. This ensures they will continue to perform when needed most.

If your cabinets have a standard lock hole pattern, you can install most aftermarket replacement locks using a hole saw and screwdriver. Hire a locksmith for more complex retrofits.
What is the most cost effective lock for light security needs?
Basic keyed cam locks provide adequate protection for low security needs at the lowest cost. Go for removable core locks so you can rekey easily.
How do I ensure my fireproof cabinet locks will work in a fire?
Use only fire rated locks certified for high temperature endurance. Thermally activated and frangible lock designs are best for fireproof cabinets.
Should I get individual locking drawers or one central lock?
For maximum security, get individual drawer locks so sensitive documents can be secured in specific drawers. But it’s less convenient than a central lock.
What maintenance should I do on filing cabinet locks?
Apply dry lubricant regularly, clean debris, inspect for damage, replace lock cores if compromised, and periodically test the locks. This ensures smooth operation and longevity.
What features help prevent lock manipulation attacks?
Hardened steel cases, concealed mounting, anti-drill pins, reinforced boltwork, and anti-pry features make locks more resistant to physical attacks.
