What can i do to avoid broken keys?

1. THE LOCK IS GETTING OLD

If a key is hard to turn, it’s time to call a technician. 

Your key is inserted into a barrel consist of pins and springs

Typically, springs will weaken over time causing the pins to sag. This misalignment of pins within the lock will cause it no longer to function. 

At this point, the lock needs to either be re-pinned or replaced altogether.

2. THE WRONG KEY 

Using the wrong key on the wrong door. Forcing the key to work will cause you to break either your key or your lock.

3. USING KEY AS A DOOR PULL

If you’re repeatedly pulling your door shut by yanking on the key still lodged in the lock, you’re going to have a problem. This puts undue stress on the key, and over time it’s going to create a weak spot. This will ultimately leave you with a broken key.

4. LEAVING A KEY IN THE LOCK

Keys that are left in the door and then broken by accidentally running into them. it’s wise to remove key from lock when isn’t currently in use to prevent any accidental bumps and breaks.

5. BENT KEYS

This seems fairly obvious, but if your key is bent, it has a weak spot. One weak spot is all it takes to break a key, so keep your eye out for bent keys. Getting a copy made beforehand is a much better option than being locked out of your facility.

6. USING YOUR KEY AS SOMETHING IT’S NOT

It’s easy to reach for your keys when you’re trying to open a box or a can and a proper opener isn't handy. However, as much as we want to use our keys for every little thing, it’s not a smart move. Using a key for anything other than its intended purpose puts undue stress on the key and can create weak spots that may cause your keys to fail when it's needed most.
 

There are several ways to end up with broken keys, but if you look at the list, they’re all fairly avoidable. Unless you decide to go keyless, paying a little attention and making responsible decisions will definitely extend the life of your key and save you from unwanted hassles.
