The Mechanics of the Shear Line

Standard residential locks operate on an intricate pin-tumbler system. Inside the cylinder plug are stacks of top and bottom brass pins of varying lengths. The correct key elevates these pins to form a perfectly flush line—the shear line—allowing the lock to turn. When you hire us to rekey door locks, our expert rekey locksmith extracts the cylinder plug, dumps out all the old pins, and inserts a completely new mathematical sequence of pins. We then cut a brand new key to match this new sequence. Any previous keys will hit a physical wall and will completely fail to turn the lock.

Streamlining with Master Key Systems

Are you tired of carrying a heavy, confusing keyring with a different key for the front door, the back patio, and the side gate? We can streamline your access. Assuming all of your locks share the same brand's keyway profile (e.g., they are all Kwikset or all Schlage), we can rekey every single door on your property to operate seamlessly on one single key!

Upgrading Security During a Rekey

A rekey is the absolute ideal time to enhance your physical defense. Standard hardware store locks are highly susceptible to "lock bumping"—a common burglary technique that uses kinetic force to make the pins jump open. While we have your lock cylinder disassembled on our workbench, we can replace standard pins with high-security "spool" or "serrated" pins. These specialized pins bind up and catch at the shear line during a bumping or picking attack, drastically thwarting unauthorized entry.

Frequently Asked Questions

Why is it better to rekey rather than replace a lock? Cost and convenience. Rekeying only costs the labor and the microscopic brass pins, rather than purchasing the heavy metal casing and latches of a brand new lockset. It also allows you to keep the hardware that currently matches your home’s aesthetic.
How long does it take to rekey a door? A skilled residential locksmith can typically remove, disassemble, re-pin, and reinstall a standard residential deadbolt in about 15 to 20 minutes per lock.
What if I don't have the original key to the lock? Normally, we use the original key to smoothly turn the plug and slide it out of the housing. If the key is permanently lost, we simply pick the lock open to access the pins. It is a completely routine process that takes only a few minutes longer.
How many new keys will I receive? Our service includes a standard set of newly cut keys. Because we operate mobile workshops with precision key-cutting machines directly on board, we can originate as many exact duplicates as your family needs before we ever leave your property.
