Short answer: A key that breaks in the cylinder, the door, or the ignition feels like a disaster, but the broken piece is often recoverable if you stop immediately and avoid the handful of mistakes that push it deeper or damage the lock.
A key that breaks in the cylinder, the door, or the ignition feels like a disaster, but the broken piece is often recoverable if you stop immediately and avoid the handful of mistakes that push it deeper or damage the lock.
The instinct to jam the other half of the key back in to 'push out' the broken piece is exactly what wedges it deeper and jams the pins, so resist it. Do not reach for superglue either, because it bonds the broken metal to the internal components far more often than it bonds the two key halves, and that turns a simple extraction into a full cylinder replacement. Avoid wrenching hard on the door handle or forcing the ignition, since torque is usually what snapped the key in the first place and more force just breaks the remaining stub further inside. If you want to add lubricant to help the piece slide, skip oily sprays that gum up over time and attract grit; a puff of powdered graphite or a dry PTFE or silicone lubricant is what locks are designed for.
If a visible piece of metal is protruding from the keyway, you have a reasonable shot at getting it yourself. Grip only the exposed metal with fine needle-nose pliers or stiff tweezers and pull straight out with steady, gentle pressure, without twisting. It helps to rotate the cylinder so the key slot is oriented key-up, letting gravity work with you instead of against you, and a light dry lubricant can ease the piece free. A cheap broken-key extractor tool, which slips a small barbed hook alongside the blade to catch its teeth, is the purpose-built version of this and worth having if it happens more than once. The rule of thumb is to stop the moment the piece stops moving or you feel it going deeper, because a few careful attempts protect the lock while repeated forcing destroys it.
If the break is flush with or below the face of the cylinder, there is nothing to grip, and getting it out without scratching or bending the internal wafers takes an extractor and a steady hand, so this is where a locksmith earns their fee. Ignition breaks are their own category: forcing tools into a steering-column lock risks damaging an expensive assembly, and if your car uses a transponder or proximity key, any replacement has to be both cut and electronically programmed to the vehicle before it will start. A mobile locksmith can typically extract the broken piece and cut a fresh key on site, with the cost varying based on whether it is a basic house key, a car blade, or a chipped key that needs programming. Whatever the outcome, once you are back in, have a spare made right away so a single worn or bent key is never your only way in again.
