The instinct to jam something in and 'jiggle it out' is exactly what turns a modest extraction into a replaced lock cylinder. Stop before you do anything: don't insert the other half of the key or a second key, since that can shove the broken piece deeper and wedge it against the pins. Don't spray oil-based lubricants like WD-40 into an ignition — they can gum up the wafers or affect electronics. If the car is running or sitting in an unsafe spot, deal with safety before the key. And skip the popular super-glue trick; done wrong, it bonds the broken stub permanently inside the cylinder and all but guarantees a professional repair.
If a good length of the blade is still sticking out of the lock, you have a fair shot at a clean DIY extraction. Grip the exposed metal straight-on with fine needle-nose pliers or tweezers and pull gently in line with the keyway — no twisting, no wiggling. A dedicated broken-key extractor tool, an inexpensive thin hook you slide alongside the blade to catch its teeth, is the right instrument for pieces sitting closer to flush. A small amount of dry graphite lubricant can ease movement without the mess or risk of oil. Work slowly, and if the piece doesn't come free with light, steady effort, treat that as a signal to stop rather than force it.
Some situations are pro-only, full stop. A key broken off inside the ignition cylinder is delicate work — the wafers and steering-lock mechanism are easy to damage and expensive to replace, so it's rarely worth the risk. A fragment that's fully flush or buried where you can't get a grip, a key that snapped because the lock itself is worn or seizing, or any broken key on a transponder or high-security system all call for a locksmith. A pro can usually extract the piece and cut a fresh working key on-site, and paying for that is almost always cheaper than repairing a cylinder you cracked trying to save a service fee.
