Has a key snapped in your lock? Here’s what to do

Picture the scene. You’ve heard the dreaded *snap*. You pull your hand away and…half of the key is stuck in the lock. At this moment, it’s easy to panic. Whether you’re trying to get into your house after a long day or lock up before a trip, a key stuck in the door can feel like a major disaster.

But don’t worry, it’s a very common problem, and in many cases, it can be fixed without a full lock replacement. We’ll show you how to safely deal with a broken key, what to avoid, and when to call a professional.

First, take a deep breath: What not to do

Your first reaction might be to grab the broken part of the key and try to force the fragment out. Please don’t! This is the most common mistake and can push the broken piece even deeper into the lock, making it much harder to remove.

Avoid these common mistakes:

• Forcing the key or trying to turn the barrel.
• Using superglue or similar adhesives on the key or a tool. This can permanently ruin your lock.
• Using a screwdriver or other tool not designed for lock mechanisms, which can cause internal damage.

DIY Methods: How to Get a Broken Key Out of a Lock

If a piece of the key is still sticking out of the lock, you might be able to remove the broken key yourself with a little care and the right tools.

1. Lubricate the lock: Spray a small amount of a dry lubricant, such as graphite powder or silicone spray, into the lock. This helps to loosen the key. Important: Do not use oil-based lubricants like standard WD-40, as they can attract dirt and debris over time.
2. Use a pair of pliers: If a good portion of the key is sticking out, a pair of needle-nose pliers or tweezers can be an effective tool. Grip the broken piece firmly and pull it straight out, avoiding any twisting motion that could cause it to get caught.
3. Try a key extractor tool: This specialised tool is designed specifically for this problem. Insert the thin, hooked end of the extractor into the lock, hook the key, and gently pull it out. These tools are affordable and often worth having in your toolbox.

When to call a professional for broken key in lock removal

Sometimes, a DIY fix isn’t the best or safest option. It’s always better to call a professional than to risk damaging your lock and needing a full replacement.

You should call a professional locksmith if:

• The key has snapped off flush with the lock and you have nothing to grip.
• The lock is stiff or was already hard to turn before the key broke.
• You are locked out of your home.
• The lock is a high-security model (like an anti-snap Euro cylinder).
• You’ve tried a DIY fix and nothing has worked.

A professional locksmith has the specialised tools and expertise to safely remove the broken key in lock without causing further damage to the lock mechanism. In many cases, they can even cut a new key from the broken pieces, saving you time and money.
