Key Snapped in the Lock? What to Do Next

A snapped key is common with worn keys and stiff cylinders — especially in cold weather. The goal is to remove the broken piece without pushing it deeper or damaging the lock.

---

Step 1) Check how the key snapped

• If the key broke while turning, the lock may be under tension.
• If it broke while inserting/removing, it’s usually easier to extract.

If the lock is mid-turn, avoid forcing it further.

Step 2) If the key is sticking out at all

Try needle-nose pliers:

• grip firmly
• pull straight out (don’t twist)

If you can see 2–3mm, extraction is often straightforward.

Step 3) If it’s flush inside the keyway

Safer options:

• a broken key extractor tool (inexpensive, designed for this)
• a thin hooked pick (carefully)

Avoid thick objects that will push the fragment deeper.

Step 4) What not to do

Avoid:

• screwdrivers, knives, or anything bulky
• pouring oil inside the cylinder (can attract dirt and worsen sticking)
• drilling (last resort, and usually avoidable with proper tools)

When you should call a locksmith

• the fragment is fully recessed and won’t hook
• the lock is stiff and the key keeps binding
• the door is your only entry and you can’t risk damage
• your cylinder is old and you want a clean replacement

Sometimes the most cost-effective solution is simply replacing the cylinder with a new set of keys.
