The Science of the Shear Line

Standard residential locks operate on a complex pin-tumbler system. Inside the cylinder plug are stacks of tiny 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 smoothly. When you hire us to rekey door locks, we extract the cylinder plug, empty out the old pins, and insert a completely new mathematical sequence of pins. We then cut a brand new key to match this new sequence. Any previous keys will fail to align the pins and will hit a physical wall, refusing to turn the lock.

Streamlining with Master Key Systems

Do you have a different key for your front door, back door, and garage? As an expert rekey locksmith, we can eliminate the heavy bulk on your keyring. Assuming all of your locks share the same brand's keyway profile (e.g., all Kwikset or all Schlage), we can rekey every single door on your property to operate seamlessly on one single key, making your daily routine much easier.

Upgrading Security During a Rekey

A rekey is the absolute perfect time to enhance your physical security. Standard locks are highly susceptible to "lock bumping"—a burglary technique that forces pins to jump the shear line. While we have your lock cylinder disassembled on our workbench, we can replace standard driver 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 increasing the difficulty of unauthorized entry.

Frequently Asked Questions

Why is it better to rekey rather than replace a lock? Cost and aesthetics. Rekeying only costs the labor and the microscopic brass pins, rather than purchasing the heavy metal casing and latches of a brand new lock. It also allows you to keep the hardware that currently matches your home’s beautiful decor.
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 remove it from 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 new keys. Because we operate mobile workshops with key-cutting machines directly on board, we can originate as many exact duplicates as your family needs before we even leave your driveway.
