### How to Prepare the Lock for Extraction
Before attempting to remove the broken key, it’s essential to make the necessary preparations, assess the situation, and determine the best course of action to maximize your chances of success.
#### Lubricate the Lock
The first step in removing a broken key from a door lock is lubrication. This reduces friction and makes the key easier to move. For internal doors, where conditions are typically dry, a dry lubricant like a spray lubricant is recommended. For external locks, which are more likely to encounter damp conditions, a Teflon or silicone-based lubricant would be preferable.
Avoid using oil-based lubricants, such as WD-40, if possible, as they can interfere with the lock’s performance. However, if this is all you have available, it’s acceptable to use it temporarily. Be sure to re-lubricate the lock with a more suitable lubricant after removing the broken key.
Spray the lubricant directly into the keyhole, then use a rag or tea towel to wipe away any excess residue from the key side and the exterior of the lock to ensure a clean workspace.
#### Assess the Situation
Once the lock is lubricated, it’s time to evaluate the situation. Start by checking how much of the broken key is visible from the lock. If the key has broken off so that a sharp edge is protruding from the lock, it will be much easier to extract because it will be simpler to grip and pull out.
On the other hand, removing the key will likely be more challenging if it has broken flush with the lock or is even further inside. In such cases, you may need to consider more advanced methods.
### Common Tools for Broken Key Removal
Several tools can be used to extract a broken key from a lock, and the choice depends on the type of lock and your preference. Here are some of the most commonly used tools:
- **Tweezers or Needle-Nose Pliers**
- **Paperclips or Hairpins**
- **Superglue**
#### Tweezers or Needle-Nose Pliers
Tweezers or needle-nose pliers can be useful for gripping and removing a partially protruding broken key. However, it’s important to pay attention to the thickness of the tweezers or pliers you use. If they are too thick, they could push the broken key further into the lock. Ideally, your tweezers should be wide enough to fit around the key without being so thick that they can’t fit along the sides.
If you can see part of the key protruding from the lock, tweezers will likely provide the best chance of success. They offer the precision needed to remove the key quickly. Be cautious not to squeeze too hard on the tweezers, as closing them will slightly push the key back. Each failed attempt will make it harder to remove the key.
#### Paperclips or Hairpins
Another household item that can be helpful for broken key extraction is a paperclip or hairpin, especially if the key is flush with the keyway or has broken deeper into the lock.
To use this method, straighten two paperclips until they form thin metal lines and align them on either side of the broken key. Insert them just enough to apply pressure. Slowly pull the broken key toward you. It may only move a little at a time, so patience is key. Repeat the process until the key is fully out. If you’re struggling, you can try turning your wrist inward while the paperclips are still in the keyway to twist and jiggle the key slightly, making it easier to retrieve.
#### Superglue
If you're feeling adventurous and have experience with delicate tasks like the game Operation, the superglue method could work for you. This method should be considered a last resort due to its riskiness and potential to damage your lock. It also only works if the broken key is somewhat accessible. The idea is to find a small piece of wire, a matchstick, or something similar that can fit in the keyhole. Apply a single drop of superglue to the end of the object and carefully insert it into the lock, avoiding contact with the sides.
Hold the wire or matchstick against the key, being careful not to push it, and wait a few minutes for the glue to dry and bind to the key. You should then be able to remove the object and pull out the key with it.
### Advanced Tools for Broken Key Extraction
If common household items aren't cutting it and you're not ready to call in the professionals, there are more advanced tools and techniques you can try if you're feeling confident enough.
Specialty tools such as key extractor tools and hacksaw or jigsaw blades can significantly increase your chances of success.
#### Hacksaw or Jigsaw Blade Method
Small jigsaw or hacksaw blades can function as key extractors. If the serrations on the blade are angled, you can often push them into the top part of the keyhole, ensuring the serrations point back toward you. Push the blade deep into the lock and position it so the serrations can hook onto the broken part of the key. Once you feel the blade latch onto the key, give it a slight twist and pull, and the broken key should slide out smoothly.
Remember not to force the blade into the keyhole; it should fit smoothly. If it doesn’t, adjust the blade to make it thin enough to fit.
#### Key Extraction Tools
It might surprise you that a tool specifically designed for extracting broken keys exists. This tool is what professional locksmiths use in these situations. While you may not need it often, it can come in handy unexpectedly. If you live near a hardware store and have time, we recommend picking one up, as it’s the easiest and safest way to remove a key.
This tool works similarly to the hacksaw blade method. Place it inside the keyhole alongside the key’s biting (serrated) edge. You’ll then be able to try to hook the teeth on the key with the hooks of the extractor. When you feel it catch, turn and pull the key out smoothly. It might take several attempts, but it’s the best method.
