Broken Key Extraction in Auburn Mills

In the parking lot your car key snapped in the driver's door. You are holding the plastic head with the buttons on it, the metal blade is inside the lock, and the spare is on a hook at home.

Broken Key Extraction

In plain words

If a key has just snapped in your lock, the most helpful thing you can do is nothing further to the lock. Keep the half in your hand, note whether the door is locked, and resist the tweezers and the glue, both of which push the piece deeper and add material the locksmith must clear first. On the phone, describe the lock, whether any of the blade shows, and whether the key turned when it broke. Have photo identification to hand, or the ownership papers if it is a vehicle. That short conversation means the locksmith arrives with the right extractors and a plan.

Sound familiar?

Overnight the deadbolt froze, and this morning the key would only turn partway. One more push and it sheared off flush with the face of the cylinder. There is nothing left to grip, and the cold is not helping.

How the visit goes

Auburn Mills

How the visit goes

  1. How the piece is sitting

    The first look is at the fragment itself, without touching it. Does any of the blade show above the cylinder face, or is it flush or deeper still? Is the plug sitting at its normal rest position, or did it stop partway round when the key gave way? A protruding piece in a resting plug is the simplest case. A fragment past the shear line in a rotated plug means the pins are holding it, and the plug has to be brought back before anything will slide. Reading this correctly decides which extractor comes out of the case and spares the keyway from needless probing.

  2. Cutting the key you leave with

    Once the lock is clear, a replacement key is made. The two halves of the broken key are laid together and the cuts are read with a key gauge, or the locksmith cuts from the key code if you have the tag or the lock's records, or from a crisp spare. What is avoided is copying a worn original, because a duplicate inherits every rounded cut and will stick and wear the same way. The new key is cut on a code machine, tried in the lock with the door open, then closed, and from both sides. Extra copies are cut from the new key while the machine is set.

  3. A lock that turns like it should

    The visit closes with the lock proving itself. The new key goes in fully, turns through its full travel and comes out without a catch, from both sides, first with the door swung open, then with it shut against the strike. The bolt is watched seating fully in its pocket. You are shown the fragment that came out and told what condition the cylinder was in. Anything the locksmith noticed, a strike screw backing out or a hinge that has dropped, is pointed out so it is not a surprise later. The door is locked with your own new key as the last act of the visit.

What affects the quote

Same fees day, night or weekend

  1. 1Whether the plug turned before the break

    A key that snapped mid-turn leaves the plug rotated and the pins holding the fragment. Easing the plug back to rest before extraction is an extra step in the work.

  2. 2Where the key broke

    A house deadbolt, a knob, an older mortise case, a padlock, a car door and a vehicle ignition each call for different access and different care, and the quote follows the hardware.

  3. 3Rekeying other doors to match

    If the cylinder ends up rekeyed or replaced, matching the other exterior locks to the new key is priced per cylinder, and simplest while the locksmith is already there.

Broken Key Extraction: questions

Do you need my spare key?

It helps if there is one. A crisp spare is the ideal pattern for the replacement, better than the broken halves and far better than a worn copy. It also lets the locksmith test the cylinder the moment the fragment is out, which shows whether the pins and springs are sound. If the spare is itself bent or worn, mention that too; it is a candidate for retirement rather than a pattern.

What lubricant should I use on the lock afterwards?

Whatever the lock's own maker specifies, since cylinders differ: many call for a dry graphite or PTFE spray blown into the keyway and worked in with the key, once or twice a year, while others prohibit graphite and specify their own product instead. General-purpose oils, grease and sprays feel smooth at first but on most cylinders collect dust and clog the pins, which leads back to the sticking that breaks keys. A little goes a long way; too much of any lubricant can also hold moisture.

The key broke while the door was locked. Can you still get me in?

Yes. The fragment comes out first, because nothing else can happen while it blocks the keyway. With the cylinder clear and the plug at rest, the door is opened by the same non-destructive methods used for any lockout, then a working key is cut and tested. If the door is a rental, the visit is noted for the building manager on request.
