Before we dive into how to fix the problem, it helps to understand why it happened in the first place. Keys don’t just snap for no reason—there’s usually an underlying issue. Here are some of the most common causes:
Keys go through a lot over the years. If you’ve been using the same key for a long time, the constant turning, inserting, and pulling can weaken the metal. Small cracks might not be visible, but eventually, they lead to a break.
Locks sometimes get stiff—especially in cold weather. If a lock feels jammed, forcing the key to turn can put too much stress on the metal, causing it to snap.
Not all keys are made equal. Some cheap key copies are cut from weaker materials, making them more prone to breaking.
In winter, locks can freeze, making it hard to turn the key. Rust can also build up inside the lock, causing resistance when you insert the key.
It’s easy to panic, but don’t start jamming things into the lock in an attempt to fix it. Take a deep breath and look at the situation.
✅ Is the broken piece visible? If a small part of the key is still sticking out, you have a better chance of getting it out yourself.
✅ Is the door locked or unlocked? If the door was already unlocked before the key snapped, you can wait to fix it. If it’s locked and you’re stuck outside, you might need a faster solution.
✅ Do you have a spare key? If you do, great! That means the lock itself is likely still working—you just need to get the broken piece out.
If part of the key is still sticking out, you can try a few safe techniques before calling a locksmith.
⚠ Warning: Avoid thick tweezers, as they might push the key deeper into the lock.
⚠ Warning: If glue seeps into the lock, it could ruin it entirely.
🚫 Don’t keep turning the key – This could push the broken piece deeper.
🚫 Don’t stick random objects inside – Paperclips, knives, or other tools might damage the lock.
🚫 Don’t spray WD-40 inside – It might seem like a good idea, but oil-based lubricants can attract dust and cause long-term issues.
🚫 Don’t force it out if it’s not budging – You could make the situation worse.
If the key is stuck too deep or none of the DIY methods work, it’s time to call a professional. Locksmiths have the right tools to remove broken keys without damaging the lock.
Here’s when you should call a locksmith:
🔹 The key is fully inside the lock, with no visible part to grab.
🔹 The lock won’t turn even after the key is removed.
🔹 You don’t have a spare key and need a replacement.
🔹 The lock is damaged or showing signs of wear.
💡 Tip: If you need emergency locksmith services, look for one that offers 24/7 callouts.
No one wants to deal with a snapped key again, so here’s how to make sure it doesn’t happen in the future:
✅ Use a High-Quality Key – Cheap keys wear down quickly. If yours is getting worn, get a stronger replacement made.
✅ Lubricate Your Locks – A graphite-based lubricant (not oil-based) keeps locks smooth.
✅ Replace Stiff Locks – If your lock is hard to turn, don’t wait—get it fixed before it breaks your key.
✅ Warm Up Frozen Locks – If it’s winter and your lock is frozen, try warming the key with a lighter before inserting it.
✅ Consider Upgrading to a Smart Lock – No key, no breakage! A keyless smart lock means you’ll never have to worry about snapped keys again.
A broken key in the lock is frustrating, but it doesn’t have to be a disaster. By staying calm and trying a few safe techniques, you might be able to get it out yourself. If not, a professional locksmith can quickly remove it and cut you a new key.
And remember—taking care of your locks and using high-quality keys can help prevent this problem from happening again.
