What to do when a key breaks inside the lock?
You get closer to home, You insert the key as usual… and crack!! Part of the key stays inside. Your heart races, you look around, and probably your first impulse is: “How do I get it myself?”?”
This type of situation is much more common than you imagine.. In The Locksmith, your locksmith in Tarragona, We deal with emergencies every day due to broken keys inside locks., whether in homes, cars or commercial premises. But if we have learned something in more than a decade of experience, is this: Picking the lock or trying home solutions almost always makes the problem worse..
That's why, This article has a clear focus: inform you, help you understand the reason for the problem and - above all - recommend when you should call a locksmith without wasting time.
Previous step: adjust the cylinder and lubricate the lock
Before any action, If you are still tempted to try to remove the key yourself, there is only one preparation that can help you (and it doesn't damage the lock): lubricate and correctly position the cylinder.
- Spray a non-greasy lubricant, like WD-40, inside the slot where the key was left. This reduces friction.
- Align the cylinder with the same position it had when you inserted the key (usually in closed or open position).
- Don't use force. If the key is stuck diagonally or crooked, any pressure can push it further in or deform it.
In many cases that we have attended, The client confesses to us that he tried to remove the key with a screwdriver or pliers, and not getting it, ended up bending the cylinder inside or breaking parts of the mechanism. Result: a completely unusable lock and a higher repair cost.
Home methods to remove a broken key (but we don't recommend them)
There are methods spread on the internet that promise to “solve it yourself” with homemade objects.. We explain them to you only for informational purposes, because as professional locksmiths we know that their effectiveness is very limited and, In many cases, dangerous.
1. Metal clip made of hook
Some people straighten a paper clip and bend it as a hook to hook the tip of the key. The problem is that requires millimeter precision and can push the key deeper if done wrong.
2. Powerful magnet
Neodymium magnets can help you only if the key is made of a metal that responds to magnetic attraction. Even so, The force necessary to extract it is usually greater than that offered by the magnet.
3. Melted BIC pen or hot silicone
Some DIYers suggest inserting a silicone stick or the plastic from a melted pen over the fragment, wait for it to harden, and throw. but this can leave plastic residue in the lock, that when it cools, make any professional extraction even more difficult.
4. Tweezers or needle nose pliers
Only useful if the fragment protrudes from the cylinder. But, again, any twisted movement can damage the internal lock drum, making a complete change necessary.
⚠️ Professional conclusion: many of these methods work only on highly edited videos. In practice, increase the risk of rendering the lock useless.
When not to try it alone: risk signs
If you see any of these signs, Don't even think about trying to remove the key yourself.. Call a professional locksmith directly:
- The key is completely inserted inside, no visible part.
- When trying to get it out, the cylinder rotates halfway or is blocked.
