A damaged door lock is a security concern that shouldn't be ignored. A professional can perform lock repairs or replacements as needed, but it can be helpful to understand the common causes of broken locks so that you can minimize the risk for your home. Here's what you should know.

What Are Some Reasons for Broken Door Locks?

1. Security Breaches

Intruders often damage door locks in their attempts to enter buildings. They may use a crowbar, club, or similar tool to physically break it and access the locking mechanism. 

Some criminals might also try to pick the lock. The springs are designed to withstand the movement of a key lifting the pins, and even though lock picking isn't as destructive as physically destroying the mechanism, it can still be intense enough to deform or break the springs.

2. Weatherstripping

Weatherstripping effectively seals the tight spots around doors and windows, helping insulate your home. However, if the weatherstripping around a door isn't installed properly, or it starts to loosen or break down, it can interfere with the movement of the lock. It can also cause exterior paint to wear away, which can trigger decay in the door and doorjamb; this can destroy the lock hatch from the inside.

3. Dirt & Grime

Over time, dirt and grime can naturally accumulate inside the intricate workings of a lock. This debris will clog the mechanism and impair its function. In extreme cases, it can prevent the lock from responding at all when you try to turn the key. 

A graphite spray or silicone-based lubricant directed into the lock can prevent and sometimes fix this issue, but if it doesn't, you'll need to contact a professional for lock repairs. Bear in mind that oil-based lubricants, like WD-40®, should never be used on locks, or more damage could result.
