1. Type of key?
The brand is Phillips but they make various types. The type here is (not sure of the correct jargon) without vertical ridges and notches. And both sides of the key are identical.
I’ve looked at some diagrams of key types and I’m not sure exactly. Is it a “dimple key”? Something else?
2. How to remove broken part from lock?
Location: Door between bedroom and garden.
Situation:
-
Someone bent the key a little, and it was stuck, couldn’t get it out. On the inside of the door. At that point still able to lock and unlock from the inside only. Using other key from the outside does nothing, doesn’t even turn.
-
I tried gently straightening it but it immediately snapped.
-
Now: can still open and close the door using the handle. Can still, with difficulty, lock and unlock the door (from inside only) by carefully pressing the head of the key against what is in the lock and turning.
A lot of info online for removing broken key blades from locks are for the “traditional” kind of key with vertical ridges and notches.
I have a screwdriver that fits all the screws and I can access all sides of the lock (inside, outside, edge), but I’m not sure if that’s relevant. I’ve tried tweezers but it’s too snug.
If I need more tools or equipment, I’ll get them tomorrow.

I would remove it from the door, apply sewing machine oil and then slam it onto a surface until a part appears that I can grab with pliers.
I have never done this and it might not work but destroy your lock.
Main problem seems solved but I just want to point out that this is not a super secure or modern lock.
Very unlikely anyone will ever actually try picking the lock on your house, BUT if they did, this lock won’t do an incredible amount to stop them.
While an ignorant rober is trying his luck at trying to open your door a smart one is already gone with your stuff and the police already blasted your door open. I would just get a normal key.
This type of keyhole is generally harder to pick than a regular barded key. Well, obviously not when the key is stuck in the keyhole.

There’s a pretty good chance that you can get a bit of wire or a fine pick and push the key through from the other side, I’d be trying that first.
Aside from that the next easiest solution is likely to just disassemble the lock and replace the cylinder as others have suggested.
Also, remember to use a lot of lube (WD-40 would me my pick)
Hot glue gun glue stick. Melt end, attach, wait a few, pull.
Very small, precision needle-nose pliers work as well, but there needs to at least be a very small part of the key-break to grab. If the key somehow snaps in a position that’s even slightly recessed, I’ve used a tootpick and tiny dab of superglue (not enough to spread and touch the lock itself - be careful lol).
I saw this on TikTok once /jk
Yep. I’ve also used a paper clip, straightened out with a very small bend at the end.
I’ve also used chewing gum, though you have to wait it for it to harden a little. Duct tape might work too.
You only have to get it to move out a tiny amount. Then you can get a pair of needle nose pliers on it and pull it out.
That particular key looks challenging though.
Tried a dab of super glue on a paper clip then held to the key?
Not likely enough surface area for cyanoacrylate to do its magic, though one could try to glue the key pieces together and hope it holds long enough for a partial pull. Likely to just glue the broken piece in there by accident.
Hot glue is gooey and will grab the broken part.
I would have thought you’d struggle to get hot glue to bond sufficiently the metal or be able to get a small enough amount on a something thin enough quickly enough to get it to stick to the key end without getting all over the barrel.
Unlock the door and remove those screws holding the latch in the door.
Once you’ve removed the lock you should be able to disassemble it and push the stuck key out or worst case, replace the lock cylinder.
This is the answer.
The only downside is you can see how stripped those screws are even in this photo. That’ll be fun.
On this type of latch (mortise) the third screw is often stripped (because it’s a set screw that holds the lock cylinder in place and often the notch in the cylinder is misaligned / on the wrong side) but _un_screwing it should be easy.
The cylinder itself, however, is usually finely threaded and can require a fair amount of torque to get started, especially without using the key for additional purchase.
Yep. Use a rubber band in the screw when trying to unscrew it to help with a bit extra grip and then never use those screws again either. Either that or use a Dremel to turn it into a flat head screw and remove them.
Dental pick, like the kind that your hygienist uses to give you PTSD should do the trick.
OP’s description of trying to pull the key out when it broke, makes me think the key may also be bound/frozen in the lock. I don’t think you’re supposed to use wet lubricants in a lock, but they may need to use a penetrating lubricant (like wd-40) along with the dental pick.
An $8 dental kit has been a life saver in so many situations.
Or slightly more expensive, if legal in your area, are actual locksmith tools.
I have a pick set I busted out this morning to unlock a pad lock on our circuit breaker (outside for some stupid reason, locked because its a new development and we had construction workers turn the house off while me and the wife were the only people on our respective jobs working the shift remotely)
We need power to run desktops. A UPS is handy, but its a bandaid to shut down correctly until power is restored fully.
Use a broken key extractor.
Wouldn’t a functioning key extractor work better than a broken one?
I like the cut of your jib.
Neat! Didn’t know there was such a thing. Another poster suggested a dental pick kit, not as good but more versatile.
You can dental pick a lock, but can you lock pick a dentist?
Strong magnet maybe?
thanks david
Dimple lock. The pins move sideways instead of up and down. Not familiar with the brand.
You could try and straighten a small fish hook to remove the broken key.
Why wouldn’t you just replace the whole lock?
This. Some people don’t realise how ridiculously easy it is to change a lock when you can open the door with a key.
-
Put the working key into the lock
-
Undo this screw
-
Turn the key slightly back and forth whilst pulling the cylinder out until it starts to come out. Then just pull it all out.
-
Mark which side was front and back
-
Measure from the middle locking mechanism of the cylinder to the ends.
-
Find a lock with the same lengths. It’ll be like 60/40 (100mm total length).
6b. Optional: get one with a fixed turnkey on the inside.
- Replace lock by reverse.

Any time I’ve had a key stuck like this I’ve used something sharp and just stabbed it down into the top of the key and leveraged it against the lock itself. Keys are way softer than people think.
I’m pretty strong for being a middle aged woman (so not strong in general), and I can break a key in a lock relatively easily with just my hands.
Uh… can I have your number?
I got a key out of a similar situation in the folks RV the other day using a small flat screw driver and a knife to pinch the key and pull it out…
Superglue the key back together, let it set, and pull it out.
Be careful not to use too much glue and br sure it’s set before you pull.
Alternatively, try needle nose pliers or a hook if you can get any purchase on the key remains.
They also sell extractors but the above suggestions will probably work.
If all else fails, call a locksmith.
I’d drill into the thickest part with a small drill, then tilt it and gently pull it out with the key.
