How to Handle a Broken Key in the Lock Without Causing Damage
It always happens at the worst moment—you insert your key, turn it, and snap—half of it is stuck in the lock. A broken key is more than just frustrating; it can lead to a costly lock repair if not handled correctly.
At Affordable Security Locksmith And Alarm, we help Phoenix homeowners deal with broken keys quickly and without further damage. If it happens to you, here’s what to do (and not do) next.
Need help now? Our Phoenix locksmiths specialize in fast, safe key extraction
Step 1: Stop Turning or Forcing the Key
If part of the key is still sticking out of the lock, your first instinct might be to twist or pull harder. Don’t. This can push the broken piece deeper inside or damage the pins and cylinder.
Step away, take a deep breath, and follow these safer steps.
Step 2: Determine If the Key Is Visible
If part of the key is visible and sticking out, you may be able to remove it with a pair of needle-nose pliers or tweezers. Grip it gently and pull it straight out—don’t twist.
If the key is flush or deep inside, you’ll need a different approach or a professional locksmith.
Step 3: Use a Broken Key Extractor Tool
Locksmiths use slim extractor tools specifically designed to hook onto the broken key and slide it out without damaging the internal pins. You can find these tools online, but be cautious—forcing it without proper skill could damage the lock.
We recommend calling a professional unless you’re confident in the technique.
Step 4: Lubricate the Lock (Optional)
If the key fragment is stuck, a graphite or silicone-based lubricant can sometimes help ease it out. Avoid using oil-based sprays like WD-40, especially in Phoenix’s dusty climate—they attract grime and can clog the lock.
Step 5: Don’t Push It In Further
It might be tempting to try inserting the other half of the key to “push” the broken piece out, but this can make things worse. You could jam the lock permanently or misalign the internal pins.
