Remove Broken Key From Deadbolt


Introduction: Remove Broken Key From Deadbolt

Sorry. Not eloquent today.

Going to work. Closed door. Deadbolt. Key broke off.

Called locksmith. Need to drill. $200 labor. $40 parts. Disconnect.

Look online. "Deadbolt? Sucks to be you. Call a locksmith." Disconnect.

Step 1: Unlock

Tried multi-tool. No grip.

Tried tweezers. No grip.

Put end of tweezers against keyhole. Think drift punch. See picture.

Hit tweezers with multi-tool. Think hammer.

Cylinder rotated. Slightly. Kept doing. Deadbolt unlocked. Door opened.

Step 2: Unplug

Keyhole still full.

See last step. Rotate cylinder to key removal position. Tip of knife against top of key. Pry outward.


See last step. Rotate a tiny bit. Pry.


Repeat above until joyful. Spend $240 on something else.

    You can also try to lubricate a lock with WD40 and try a magnet if you have it. When you turn a key in a place where you put it in a magnet could do a favour of getting it out a bit for a better grip. Not all locks need to be drilled, at least when you have only had a broken key inside. But when lock insides get damaged you can not open a door withour removing a broken deadbolt. Though its better to leave this work to proffesionals because key extraction is far less expensive than to remove a whole lock you broke trying to get a key

    Your article is also great! You covered most of the proper actions

    Please note, the key will not come out unless the keyway is vertical. There are tools made specifically to extract broken keys. In a pinch a straight pin may lever it out.
