Getting into a locked metal file cabinet can seem daunting, but with the right tools and techniques, it is possible to bypass many filing cabinet locks. Here is a comprehensive guide on how to get into a locked metal file cabinet.

Assess the Lock Type

The first step is to inspect the lock and identify what type it is. There are a few common lock types used on metal filing cabinets:

Key Locks

• Tubular locks – These have a cylindrical key and can often be picked open with lock picking tools. Tubular locks are very common on cheaper filing cabinets.
• Disc tumbler locks – More secure than tubular locks, disc tumbler locks use a flat key with grooves at different depths. Picking them is more difficult but can be done by an experienced lock picker.
• Wafer locks – Found on older metal cabinets, wafer locks have a simple design that is easier to pick than other key lock types.

Combination Locks

• Mechanical dial – The traditional spin dial combination lock. These can be opened by decoding the combination through manipulation.
• Digital keypad – Uses an electronic keypad to enter a code. Vulnerable to bypass methods like installed default codes.

Other Lock Types

• Magnetic locks – Uncommon but found on some models. Can be shimmed open by disrupting the magnetic field.
• Biometric locks – High-security locks using fingerprint or retina scanning. Nearly impossible to bypass.

Non-Destructive Entry Methods

The following methods can potentially open a locked metal filing cabinet without damaging it:

Picking the Lock

With practice, many standard key locks can be picked using lock picking tools like tension wrenches and pick sets. Useful for opening tubular, wafer, and basic disc tumbler locks.

Decoding the Combination

Manipulate a mechanical dial lock to determine the unlock combination through sensory input. Can take patience and skill but works on most combination dial locks.

Using Shims

Thin strips of metal can be inserted into the lock mechanism to open it through mechanical disruption. Effective on wafer locks and some tubular lock designs.

Installing a Covert Lock

Replace the lock core with a new core that you control, allowing access while retaining the original lock’s appearance.

Impressioning the Key

Metal files and blanks can be used to duplicate a key by impressioning the original. Requires having access to the original key briefly.

Destructive Entry Methods

If you need immediate access at all costs, the following destructive methods will bypass the lock security:

Drilling the Lock

A common drill bit can be used to destroy the locking mechanism, rendering it unable to lock. However, this will permanently damage the lock.

Prying the Drawer Open

Use an angled pry bar, jimmy tool, or lock puller tool to apply concentrated force and pop the drawer open. Will bend the locking bars.

Removing the Drawer

Taking the drawer entirely out of the slides is an option if the cabinet design allows it. Typically requires unscrewing or bending apart components.

Cutting through the Body

In extreme cases, cutting through the sheet metal body with an angle grinder, Jaws of Life, or other metal cutting tools will grant access.

Legal Considerations

Note that picking, decoding, or forcing entry into a filing cabinet without the owner’s permission may constitute illegal trespass and damage of property. Understand the laws in your jurisdiction before attempting to open a locked cabinet that is not your own. Proceed at your own risk.

Conclusion

A locked metal filing cabinet can be a significant physical barrier protecting sensitive information and valuables. But for those with the skills and determination, a variety of methods are available to covertly or forcibly bypass many cabinet lock designs. Understanding the strengths and limitations of different lock types allows you to devise the most practical approach to non-destructively or destructively gaining entry when absolutely needed.

FAQs about Getting into a Locked Metal File Cabinet

Here are some frequently asked questions about how to get into a locked metal file cabinet:

What are the easiest filing cabinet locks to pick open?

The easiest locks to pick open are typically tubular locks and old wafer locks. These have simple internal designs that are more vulnerable to picking methods.

Can you pick a combination lock on a filing cabinet?

Yes, mechanical dial combination locks can potentially be decoded and opened through manipulation even without knowing the actual combination. This requires skill, patience, and specialized techniques.

What tools do you need to pick open filing cabinet locks?

Useful lock picking tools include hook picks, rakes, tension wrenches, shims, and lock pick gun. Quality pick sets tailored for lock picking are ideal.

What is the fastest non-destructive way to bypass a filing cabinet lock?

Installing a covert lock core replacement can be the fastest non-destructive method if done properly. It allows access while retaining the original lock.

Can you get past high-security biometrics locks on filing cabinets?

Biometric fingerprint and retina scan cabinet locks are very difficult to bypass without authorized access credentials. Non-destructive covert entry of biometric locks is extremely challenging.

Is it illegal to force open someone else’s locked filing cabinet?

In most jurisdictions, forcing entry into a locked container or property without permission is considered trespassing and destruction of property, which can carry criminal penalties.

What are the risks of drilling open a lock on a filing cabinet?

Drilling destroys the lock mechanism, so the cabinet can no longer be locked up. This method also leaves behind physical evidence of forced entry. Use only as a last resort.

If I damage a filing cabinet getting it open, can I fix it?

You may be able to replace damaged lock cores and bent drawer components. But extensive damage like cutting through the body leaves permanent signs of break-in that are difficult to fully conceal.

Can fire department lock puller tools open a stuck filing cabinet?

Lock puller tools generate extreme leverage that can pop open stuck or locked filing cabinet drawers in some cases. They can bend components but grant access.
