Cannon Gun Safe Will Not Open: Why Won’t My Electronic Gun Safe Open?

There are five possible reasons why your electronic safe won't open. The most frequent Cannon gun safe problems are caused by:

  • Dead battery in the electronic lock
  • Incorrect combination or key
  • Jammed locking mechanism
  • Damaged lock or handle
  • Misaligned bolt work

1. Dead Batteries in Electronic Lock is One of the Easiest Cannon Gun Safe Problems to Fix

Replaceable batteries power the Cannon gun safe's lock periodically. The lock will not function when the batteries die, preventing the safe from opening. 

Solution: Replace electronic locks' batteries with new ones. A new battery will help you access your safe. Also, opt for brand-name batteries to ensure they last longer.

2. Incorrect Combination or Key

The Cannon gets into lockout mode with the wrong gun safe combination and wrong keys.

Solution: Keep your combinations and passwords secure. Memorizing the combination is even better. 

3. Jammed Locking Mechanism

If your Cannon safe is not opening, it may be because of a jammed mechanism for locking, which was also pointed out when discussing issues with opening Winchester safes. The jamming mostly happens when the bolts get aligned incorrectly or if there's debris in the mechanism.

Solution: Clean your safe and oil the hinges when they become stiff.

4. Damaged Lock or Handle Means That Your Cannon Safe Will Not Open With Correct Code

Another reason your gun safe may not open is because of a damaged lock or handle. Over time, locks and handles can wear out or become damaged, preventing the safe from opening - an issue you can maybe avoid buy investing in a more expensive safe.

In case of a deactivated code due to damaged wiring in the circuit board, contact Cannon customer service for a safe technician. Also, consider a lock replacement or repair.

5. Misaligned or Jammed Bolt Work

Your Cannon gun safe may not open with misaligned bolts. The bolts can shift out of place when you move or bump your safe. When that happens, the mechanism for locking will not function correctly, preventing the safe from opening.

Solution: Try applying force to the handle of the gun safe door or gently tap the safe. It helps free up the mechanism and allows you to open the safe.

What Do You Do if Your Safe Won’t Open?

If your Cannon safe won't open, investigate the cause, then determine the solution. For instance, if the lock has a dead battery, replace it with a fresh battery. Maybe the issue is as simple as that.

Also, try using a graphite lubricant or WD-40 to free up the mechanism. Apply the oil to the bolt work and try opening the safe again. If that doesn't suffice, go for a new one.  

You can also replace the combo lock manually, especially if you have no key and the batteries are dead.

How to Replace a Cannon Digital Safe Lock Manually

Manually replacing a Cannon digital gun safe lock is a straightforward process that requires a replacement lock and essential tools. You'll need a replacement lock compatible with your Cannon safe model. 

Once you have the new lock, follow these steps:

  1. Remove the old lock: Use a screwdriver or drill to remove the screws securing the lock to the safe. Then, pull out the key pad and lock. Removing the existing keypad from older Cannon safes is a task, but it's not complicated.
  2. Install the new lock: Insert the new lock into the same hole as the old lock. Ensure the lock is facing correctly and the screws align with the screw holes.
  3. Secure the new lock: Use a screwdriver or drill to screw in the new lock. Make sure the screws are tight and secure.
  4. Test the new lock: Enter your combination and test the new lock to ensure it works properly.

How to Open a Digital Gun-Safe When the Batteries Are Dead and No Key

First, try replacing the batteries with new ones. If this doesn't work, you can temporarily use an external battery pack or adapter to power the safe's electric lock.

If none of these options are available, you may need to use a backup key or contact a professional locksmith. Most digital safes come with a backup key that can unlock the safe manually, which may pose a bit of a hussle if you have a gun safe hidden under your bed, so remember to keep your gun safe safe and accessible.

Locate the keyhole on the safe and insert the backup key. Turn the key to unlock the safe.

If you don't have a backup key, consider a professional locksmith with experience working with digital safes. They'll help you open the safe without damaging it.

How to Open a Cannon Safe With a Magnet

In some cases, you should be able to open your Cannon safe using a rare earth magnet. For that to work, you would need to know exactly where the safe solenoid is positioned. If you place the magnet directly over the solenoid, it should unlock the safe.

People with pacemakers should never try this. Rare earth magnets can damage other electronic devices, as well. Lastly, you should put a magnet in a gym sock or you wouldn't be able to remove the magnet.
