4 Major Door Lock Problems and How to Fix Them

white door lock

A door lock is one of those things we often take for granted until it stops working correctly. Whether it’s a sticky lock, a key that won’t turn, or a lock that won’t latch properly, dealing with door lock problems can be frustrating. Like any mechanical device, door locks can malfunction over time, causing frustration and leaving you feeling vulnerable. This blog post equips you with the guide to identify and address common door lock problems, empowering you to install Chubb door locks and maintain optimal security for your home. 

Major Door Lock Problems You Can Face

Let’s explore some common door lock issues and some potential solutions you can try:

1. Hard to Operate

This is a frequent situation where your key doesn’t enter the lock smoothly or turning it feels stiff and requires more effort than usual. Here are some possible causes:

  • Dirt and Debris: Over time, dust, grime, or even tiny particles can get inside the lock mechanism. This build-up creates friction, making it critically challenging to insert or turn.
  • Worn-Out Lock: Constant use can cause wear and tear on the lock’s internal components. This can make critical operations difficult.

What You Can Do

  • Lubrication is Key: Silicone-based lubricant is also available at most hardware stores. Carefully spray a small amount into the keyhole and spray the moving parts of the lock. Do not use oil-based lubricating products because they can collect dust and worsen the issue.
  • Compressed Air Can Help: If the lubrication doesn’t improve the issue, you can try using compressed air to remove any dust or debris causing the lock to stick.

2. Jammed Door Lock

A jammed lock is nerve-wracking, especially if you’re locked out of your home. Here are some potential reasons for a jammed lock:

  • Foreign Object: Sometimes, a small object, such as a key broken off or junk, might be stuck in a lock mechanism, which makes it hard for the lock to work properly.
  • Misaligned Components: Over time, the lock or strike plate (a metal plate at the door frame receiving the lock’s bolt) can lose its alignment and lock due to jamming.

What You Can Do

  • Avoid Force: The worst thing you can do is try to force the key or pry the lock open. This can intensify the problem and ultimately lead to more extensive damage.
  • Gentle Wiggling: If you suspect the possibility of a foreign object’s stuckness, do a gentle key wiggling while putting a little pressure.

3. Broken Key

A scenario no homeowner would wish for is a stuck key in the lock. Here’s what could have caused it:

  • Worn-Out Key: Due to frequent use, keys can be ground down, and as a result, they are more prone to stop working inside the lock.
  • Incorrect Key: Applying the wrong key for a lock may lead to an extra strain on the mechanism, and the key may crack.

What You Can Do

  • Patience and Steady Hands: If the critical breaks into the lock and only a tiny part comes out, you can take it with the help of needle-nose pliers. Use extreme care and avoid pushing the failure into the lock.
  • Call a Locksmith: If you cannot fix the broken key inside the lock by yourself or lose it, it is better to call a licensed locksmith. They have all the specialized tools plus inclusive techniques for the broken key without harming the lock mechanism.

4. Key Is Not Turning The Lock

A few different factors can cause this:

  • Misaligned Components: Similar to a jammed lock, misalignment between the lock and the strike plate can prevent the key from turning smoothly or engaging the lock mechanism.
  • Damaged Internal Components: The inside components of the lock, such as springs or pins, can lose their durability after long-term use, which may result in the key turning hard and not operating well.

What You Can Do

  • Visual Inspection: Close up on the gap between the bolt and strike plate to determine if there is a vulnerability. However, this doesn’t guarantee a DIY fix is possible.
  • Seek Professional Help: For misalignment and internal damage suspicion, it’s better to use the services of professionals. They can provide the most accurate diagnosis and recommend the most efficient repair or a complete lock replacement solution.

How To Fix These Issues?

Fixing ordinary door lock issues like sticky locks, keys won’t turn, or jammed locks can often be tackled with simple solutions that don’t require calling a locksmith. Here’s how you can address these problems:


Sticky locks can often be resolved with lubrication. Start by purchasing a spray lubricant like WD-40, readily available at most hardware stores. Insert the lubricant tip into the keyhole and briefly spray a few pushes of it. Allow the penetrating motion of the lock mechanism by inserting and removing the key at some time. It is also commonly used to coat the interior of the locks so that the entire lubricant soaks up the dirt and loose rusted particles, inhibiting the locks from locking or unlocking. When familiar with the lubricant’s work, wipe off the excess with a clean cloth. 


If lubricating your lock does not ease your problem, you must clean it. Start by removing visible dirt or debris from the keyhole with a small brush or compressed air. Then, mix warm water and mild detergent in a bowl and dip a cotton swab in the solution. Clean the inside of the keyhole with the dampened swab, and scrub away any remaining dirt.

Door Lock Replacement

In other cases, problems with door locks may even be to the extent that you may have to buy a new one. If none of those solutions works by cleaning the locking mechanism, the better course of action is to get a new one. Consider buying Era front door locks that match your door size and type; pay attention to the size and type of lock you already have. Remove the screws securing the old lock to the door using a screwdriver, then carefully remove the old lock from the door. Install the new lock according to the manufacturer’s instructions, making sure to tighten the screws securely.
