Before you learn how to get broken key out of ignition, you must learn how this thing works.

In every door lock, there is a cylinder with many pins. The pins are free to move up and down in their chamber due to a spring. So when you insert your key and rotate it, those key pins get stuck in these cylinder pins and rotate, thus opening the door.

But when those pins got stuck there because you broke them, they could not move anymore, preventing them from being extracted. So the idea is simple, the cylinder must be returned to its normal position to remove the broken key from the lock.

I mean, you have to rotate it using some outside tools. So lets understand how to get a snapped key out of a lock using a few tools.

1. Use a Glue Stick to Remove the Key

Use a Glue Stick to Remove the door Key

You may have seen it, as many people create TikTok videos telling you how to get a broken key out of a lock using a glue stick. They are available in most homes if not, you can buy them online easily. 

Here is how you would remove the key from the look.

  • First, soften the tip of the glue stick and press it into the keyhole.
  • If you have softened the glue stick enough, then it will mold and harden around the key pins.
  • When it becomes hard, rotate the key and try to remove it slowly.

The glue stick tip should be pointy enough to help it reach the keyhole and attaches to the pins more accurately. 

If you can not remove the glue stick, use a nose pillar to get more grab of it, and if you do not have a glue stick, use the next idea.

2. Use Super Glue on the Tip of the Snapped Key

Use Super Glue on the Tip of the Snapped Key

People also recommend using super glue to remove the broken key. Be careful with it as it may damage the lock if you mistakenly spill the glue inside the lock.

Do the following to remove the key.

  • Put super glue on the tip of the broken key handle.
  • Then insert it in the lock.
  • Let it join with the broken key pins.
  • Then when it is attached, slowly rotate and remove the key.

It may work if your lock is not that complicated. But if any mistake happens, that glue will spill over inside of the lock thus damaging the inner mechanism of it. 

In that case, you have to take the lock out of the door and soak it in the nail polish remover to dissolve the glue. Do it carefully, or the other ideas in our list will not work anymore.

These two ideas are my feveroit on how to remove a broken key from a lock. But if you do not have the glue stick right now try the below steps.

3. Use a Broken Key Extractor

Use a Needle Nose Plier for door key removal

Everyone has a nose plier or tweezer in their home. Use it to remove the key. Just insert the nose plier into the lock, garb the broken part of the key, and then try to remove it slowly.

Do not force the nose plier, as it may get worse. Just grab it and then peacefully rotate it, and it will come out unless the inner lock mechanism is too complicated. Try it now and let me know the result of your lock problem.

5. Try Removing the Key with a Small Jigsaw Blade

7. Take the Whole Door Lock Out
