Your door lock is your first line of defense against burglars and intruders, so it is important to know when to change it. Security is a top priority for every home and business owner. In addition, the protection of your family and livelihood is paramount. So, it is essential to maintain your door hardware and replace them if necessary. However, when do you need new locks for your home or commercial property?

When to Change a Residential Door Lock

Door locks are your home’s first line of defense against intruders and are also the most vulnerable layer of a home security system. Many reasons may convince you that it is time to buy a new lock for your home.

Relationship change

If you have ended a relationship recently, whether with your spouse or a dating partner, it is wise to change your door locks to prevent that person’s unwanted access to your home. The ex-partner may still have spare keys to your home after the breakup, so changing your locks can help thwart potential troubles. The same goes if you have fallen out with a friend or roommate.

Lost or stolen keys

Change your locks if your keys have been lost or stolen. While it is simple to get replacement keys, remember that your lost or stolen keys are in the hands of a stranger who could have access to your residence when you are out. It is good practice to replace your locks whenever you lose your keys.

Moved to a new residence

Change locks if you move to a new residence occupied by someone else before you. Realtors and previous owners or tenants may have copies of the keys to your new home. If you worry about the cost, change at least the locks of all the exterior doors.


If you fall victim to a break-in, among the first things you must do is to have a residential locksmith change the locks of your doors immediately. A faulty lock compromises your security and can lead to further break-ins.

When to Change a Commercial Door Lock

Your business’ security plan includes several layers of protection — and door locks are just one brick in the wall. Experts suggest changing locks every seven years, but many factors may necessitate changing locks sooner.

Wear and tear

Manufacturers design commercial locks with long-term durability in mind. However, time and constant use will eventually depreciate even the most heavy-duty locks. Therefore, it is good practice to replace your commercial locks before reaching the end of your life and stop working efficiently.

Out-of-date locks

If your business property still uses outdated locks, consider upgrading to a more modern lock system. For good reasons, more businesses are moving from mechanical locks to keyless lock systems. Smart locks are known to offer better security than their mechanical counterparts. A professional commercial locksmith can recommend which type of lock suits your business.

Harsh weather conditions

One of the most common causes of lock issues is the changing weather conditions. As temperatures fluctuate, your mechanical door locks may jam, or your keys may break or get stuck. Switching to keyless locks can minimize these problems because they do not require inserting a key to work.
