Many people have seen videos or read stories online about opening a Sentry Safe with a magnet. This idea has become popular, especially among those locked out of their safe or curious about how safes work. But is it really possible? What is the science behind this trick, and does it work on all Sentry Safe models? More importantly, what are the legal and ethical issues to consider?
This article gives you a detailed, step-by-step look at whether you can open a Sentry Safe with a magnet. You will learn about the mechanics of Sentry Safes, the role of magnets in lock manipulation, and what risks and alternatives exist.
By the end, you will have a clear understanding of how much truth there is behind this “magnet method,” and what you should do if you are locked out of your safe.
What Is A Sentry Safe?
A Sentry Safe is a brand of home and office safes made for storing valuables, documents, and sometimes firearms. These safes are widely used because they are affordable, easy to use, and come in many types—fireproof, waterproof, digital lock, and mechanical lock versions.
Most Sentry Safes are designed for general security, not for high-level protection like bank vaults. The company’s products are found in homes, hotels, and businesses. They focus on protecting against fire, water, and casual theft.
Sentry Safes usually use one of three main locking mechanisms:
- Key lock: Simple key-based opening.
- Combination lock: A dial with a preset combination.
- Electronic lock: A keypad where you enter a code.
Some models combine these methods for added security. Understanding which type you have is important before trying any method to open it.
How Do Sentry Safe Locks Work?
To understand if a magnet can open your safe, you need to know how its lock works. Sentry Safes use two common types of locks: solenoid electronic locks and mechanical locks.
Solenoid Electronic Locks
Many Sentry Safes with keypads use a solenoid to control the locking bolt. A solenoid is a small metal coil that moves a pin when it gets electricity. When you enter the correct code, the solenoid pulls a pin, letting you turn the handle and open the safe.
Mechanical Locks
Older or basic Sentry Safes use a mechanical dial. This lock has a wheel pack inside. When you dial the correct numbers, the wheels line up and allow a “fence” to drop into place, unlocking the bolt.
Key Locks
Some Sentry Safes use or include a simple key lock. This is the most basic type, using a cut key to turn a cylinder and release the bolt.
Locking Bolts And Relockers
Most Sentry Safes also have locking bolts, thick metal pieces that block the door. Some models include a relocker—a device that triggers during forced attacks and keeps the safe locked.

The Magnet Method: How Does It Work?
The “magnet method” refers to using a strong magnet—usually a neodymium magnet—to move the solenoid inside an electronic Sentry Safe. The idea is to bypass the electronic lock and pull the solenoid pin directly, so you can open the safe without the code.
Here’s how it’s supposed to work:
- Get a very strong magnet (at least 120 pounds pull strength).
- Place the magnet on the part of the safe’s door closest to the solenoid.
- Move the magnet around until it lines up with the solenoid.
- The magnetic force pulls the solenoid pin, letting you turn the handle and open the safe.
This method only targets solenoid-based electronic locks. It does not work on mechanical dial locks or key-only locks.
Can You Really Open A Sentry Safe With A Magnet?
The short answer: Sometimes, but not always. The magnet method can open some older or cheaper Sentry Safe models with solenoid locks, but it does not work for all safes. Here’s a breakdown of the facts.
When The Magnet Method Works
- Older electronic Sentry Safes: Some models made in the early 2000s used simple solenoid locks with little shielding. A strong neodymium magnet can sometimes pull the solenoid pin through the safe wall.
- Low-end models: Cheaper safes often use less metal and less shielding, making it possible for a strong magnet to move the solenoid.
When The Magnet Method Fails
- Mechanical locks: Safes with a dial or key lock have no solenoid to move. The magnet trick does not work.
- Modern Sentry Safes: Newer models use better shielding or different lock designs, blocking magnets.
- Fireproof models: These often have thick fire insulation, which reduces the magnet’s strength.
- Bolted-down or heavy safes: Larger safes use thicker steel, making it almost impossible for an outside magnet to affect the solenoid.
Real-world Success Rate
In real life, the magnet method has a mixed success rate. Some locksmiths and hobbyists show it working on YouTube, but others find it unreliable. Often, the magnet method only works if:
- The solenoid is close to the surface.
- The safe wall is thin steel.
- The safe has no extra shielding or insulation.
Many users try and fail because their safe is newer, better built, or uses a different lock mechanism.
What Kind Of Magnet Is Required?
A regular fridge magnet will not work. The neodymium magnet used for this trick must be very strong.
Magnet Specifications
- Type: Neodymium (rare earth) magnet
- Pull strength: At least 120-150 pounds
- Size: Around 2 inches in diameter, 1 inch thick
- Cost: $30–$70 for a quality unit
These magnets are dangerous. They can pinch skin, break fingers, and destroy electronics if used carelessly.
Where To Get One
You can buy strong neodymium magnets from industrial suppliers or online. They are not toys and must be handled with care. Never use these near children or people with pacemakers.
How To Try The Magnet Method (for Educational Purposes Only)
If you own the safe and want to try the magnet method, here’s how it’s usually done. Remember: this is for information only—never use these methods illegally.
- Find the solenoid location: Usually behind the keypad area on the safe door.
- Place the magnet: Hold the magnet with thick gloves and press it against the safe door.
- Move the magnet: Slide it slowly around the keypad area, feeling for a “click” sound or change.
- Turn the handle: If you hear a “click,” try turning the handle to open the door.
Many people fail because they do not know the exact solenoid location. Even if you find it, the magnet may not have enough force to pull the pin through thick steel or insulation.
Common Mistakes
- Using a weak magnet: Only a very strong magnet works.
- Wrong location: The solenoid is often offset from the keypad.
- Ignoring safety: Strong magnets are dangerous!

Why The Magnet Method Is Not Reliable
There are several reasons why the magnet method is not a reliable way to open a Sentry Safe.
Improved Safe Designs
Sentry Safe and other manufacturers have learned about this trick. Newer safes often have:
- Thicker steel walls
- Extra shielding around the solenoid
- Different lock types (motor-driven instead of solenoid)
- Fireproof layers that block magnetic force
Manufacturing Variations
Even within the same model, safes can have small differences in construction. A trick that works on one safe may not work on another.
Safety Risks
Strong magnets can cause injuries and damage electronics. Trying this method without experience can be dangerous.
No Guarantee
Even with the right magnet and an older safe, there’s no promise the method will work. Many people end up damaging their safe or wasting time.
What Happens If You Try To Open A Safe With A Magnet?
Trying to open your own safe with a magnet can have consequences:
- Permanent lockout: If you damage the solenoid or the locking mechanism, you may never be able to open the safe again without professional help.
- Warranty void: Opening your safe using non-approved methods usually voids the warranty.
- Injury: Strong neodymium magnets can cause serious injuries.
- Legal issues: If you try this on a safe you do not own, it is illegal and can lead to criminal charges.
Legal And Ethical Issues
It is very important to remember: Only try to open a safe you own. Opening someone else’s safe is illegal, even if you think you are helping.
Laws On Safe Opening
In many countries, opening a safe without permission is considered breaking and entering or theft. Locksmiths must follow strict laws and require proof of ownership before opening a safe.
Ethics
Even if you are locked out of your own safe, using risky methods like the magnet trick can be unethical if it damages the safe or the contents inside. Always consider safer, legal alternatives.
Better Alternatives To The Magnet Method
If you are locked out of your Sentry Safe, there are better and safer options than the magnet trick.
1. Use The Backup Key
Many Sentry Safes come with a backup key. If you still have this key, use it to open your safe.
2. Contact Sentry Safe Support
The company can often help you recover your code or order a new key if you can prove ownership. Visit the official Sentry Safe support page for instructions.
3. Call A Licensed Locksmith
A professional locksmith can usually open your safe without damage. They have special tools and training.
4. Order Replacement Parts
If your safe’s lock is broken, you can order replacement parts from Sentry Safe or a locksmith.
5. Use Non-destructive Entry Tools
Some locksmiths use tools like auto-dialers or safe scopes to open safes without damage.
6. Drilling (last Resort)
As a last resort, a locksmith can drill open a Sentry Safe. This destroys part of the safe, but sometimes it is the only option.
Real-life Cases And Examples
Many people try the magnet method after seeing it online. Here are a few real-life examples to show what usually happens.
Case 1: Success With An Old Safe
A user with a 2005 electronic Sentry Safe forgot the code. They bought a 130-pound neodymium magnet, found the solenoid location, and successfully opened the safe. The safe had no extra shielding and thin walls.
Case 2: Failure With A Modern Model
Another user tried the same method on a 2022 Sentry Safe. Despite using a strong magnet, nothing happened. The safe had more shielding and a thicker door.
Case 3: Permanent Damage
A person tried the magnet trick, damaged the solenoid, and the safe would not open—even with the code. They had to pay a locksmith $200 to drill open the safe.
These examples show that the method is not guaranteed and can create more problems than it solves.
Comparison: Magnet Method Vs. Other Opening Techniques
To help you understand, here is a comparison of the magnet method with other common ways to open a Sentry Safe.

| Drilling | Very High | All models | Very High | Professional |
Are Sentry Safes Truly Secure?
Sentry Safes are designed for basic security—to keep out casual thieves or protect documents from fire. They are not meant to stop professional criminals or determined attacks.
Security Features
- Fire and water protection: Many models protect documents from heat and water.
- Basic theft resistance: The locking bolts and steel slow down thieves.
- Affordable: Good for home or office use where high security is not needed.
Limitations
- Not high-security: Thieves with tools or knowledge can open them.
- Vulnerable to attacks: Some older models are weak to prying or the magnet method.
- Better for fire protection: Their main strength is protecting from fire, not theft.
How To Improve Safe Security
If you own a Sentry Safe, here are ways to make it more secure:
- Bolt it down: Use the mounting holes to attach the safe to the floor or wall.
- Hide it: Keep the safe out of sight, not in obvious places.
- Upgrade your model: Get a newer safe with better locks and more shielding.
- Use multiple layers: Store your safe inside a locked room or closet.
- Limit access: Only trusted people should know the code or have the key.
Myths And Misunderstandings
There are many myths about opening Sentry Safes with magnets or other simple tricks.
- Myth: Any Sentry Safe can be opened with a magnet.
- Fact: Only some old models are vulnerable.
- Myth: The magnet method is quick and easy.
- Fact: It is rarely successful, and often damages the safe.
- Myth: This method is legal if you are just “testing.”
- Fact: It is only legal on your own safe.
Non-obvious Insights
Beginners often miss these important points:
- Solenoids are not always at the keypad: The position can change, so “guessing” rarely works. Many people give up after 30 minutes of sliding the magnet with no result.
- Magnets can erase data: If your Sentry Safe holds hard drives, tapes, or old film, a strong neodymium magnet can erase or destroy these items—even if you do not open the safe.
Another insight: Some locksmiths use a scoping camera to look inside the safe and find the solenoid. This is safer and more reliable than guessing with a magnet.
Should You Try The Magnet Method?
For most people, the answer is no. The risks—injury, damage, voiding your warranty, and possible legal trouble—are not worth it. If you are locked out of your Sentry Safe, contact the company or a licensed locksmith. Professional help is safer, faster, and often cheaper in the long run.
Final Thoughts
The idea of opening a Sentry Safe with a magnet is popular online, but it is rarely successful in real life. Only old, unshielded models with solenoid locks are vulnerable, and even then, the process is tricky and risky. Modern Sentry Safes are much harder to open with this method due to better shielding and design changes.
If you are locked out, safer methods exist—backup keys, support from the manufacturer, or professional locksmiths. The magnet trick is not a magic solution, and trying it can cause more harm than good.
Always protect your safe’s code and key, keep records in a secure place, and never try risky methods unless you are prepared for possible damage. For more information on safe security and lock design, you can visit Wikipedia’s Safe page.
