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’ve had luck melting a hot glue stick and pressing it on the head, letting it cool, and pulling it out, but you would also be best replacing the lock since you can open the door
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.
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.
Strong magnet maybe?
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)
superglue.
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?
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.
Hot glue gun glue stick. Melt end, attach, wait a few, pull.
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.
I’d drill into the thickest part with a small drill, then tilt it and gently pull it out with the key.
This looks like a similar setup to some security doors I’ve messed with.
Edit: what about using a unfolded paperclip and push from the other side. The plan I had when I started writing this probably won’t work as accessing the key cylinder will only likely get access the keyhole.
Edit2 id also hit it with a spray from a can of WD-40 (lubricant) and hope that helps work things loose.
Below is probably useless but it was my train if thought initially.
They have a removable part so the locks can be rekeyed easily by a locksmith by replacing some pins on the inside to match the keys.
Edit 3 if removing fails and you need to replace a part, you probably could get away with just replacing the locking part and not the whole handle mechanism.
In the ones Ive used a screw on the door matches up holding the locking cylinder component. Probably the one just above the deadbolt.
Try unscrewing this to see if the cylinder the key is stuck in can be removed.
Go very carefully as I don’t know what is actually holding the stack of pins which match your key and if these pins fall out, finding which go where will be very hard and very fiddly.
WD-40 is not a lubricant, it can do it short term, but makes things worse long term.
WD-40 literally stands for Water Displacement - Formula 40.
Its to keep mechanical components hydrophobic so they don’t rust or otherwise degrade due to the presence of water.
For locks and keyways, you want powdered graphite as a lubricant. I keep a small tube (puffer style) in my pick kit if needed.
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.
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.
Some superglue on the broken part of the key and reattach it, or alternatively superglue a few paper clips or other thin metal objects to the key in the door. Using more than one will spread out the force used to pull.
