Lock Rekeying, Repair, and Security Upgrades in Los Angeles, CA


When you move into a new home, fire a disgruntled employee, or lose a set of keys, your property's security is compromised. You don't know who has a copy of your key. However, running out to the hardware store to buy entirely new locksets is often an expensive and unnecessary hassle. We provide professional lock rekeying and repair services across Los Angeles, CA. We manipulate the internal mechanics of your existing hardware, rendering old keys useless and restoring total access control to your property for a fraction of the cost of replacement.

The Science of Lock Rekeying


A standard deadbolt contains a cylinder filled with small brass pins of varying lengths. The correct key pushes these pins to a perfectly aligned "shear line," allowing the cylinder to turn. When we rekey a lock, we remove the cylinder, discard the old pins, and insert brand new pins that correspond to a completely different key pattern. Your old hardware remains on the door, but the old keys will never turn it again. We then provide you with a fresh set of keys.

High-Security Lock Upgrades


Standard hardware store deadbolts are highly vulnerable to lock bumping and drilling. If you want to fortify your home's perimeter, we install high-security cylinders (such as Medeco, Schlage Primus, or Mul-T-Lock). These locks feature anti-drill hardened steel inserts, side-bitting pin variations, and restricted keyways, meaning nobody can duplicate your key without your authorized signature card.





Frequently Asked Questions


  • Is it cheaper to rekey or replace a lock? Rekeying is significantly cheaper. You are only paying for the labor and the microscopic brass pins, rather than buying the heavy metal housing of a brand new lockset.
  • Can any two locks be keyed to match? They must share the same keyway profile (e.g., both must be Schlage style, or both Kwikset style). If you have mismatched brands on your front and back doors, we can often replace the cylinder core of one so they match, allowing you to use one key for both.
  • My door lock is sticky and hard to turn. Does it need replacing? Often, no. Locks accumulate dirt and the internal springs wear out. We can disassemble the lock, clean it, lubricate the pins with specialized graphite or Teflon sprays, and repair it to smooth functioning.
  • What is a bump key? A bump key is a specially cut key used by criminals to force the pins inside a standard lock to jump to the shear line, opening the door in seconds with no signs of forced entry. We install bump-resistant pins and high-security locks to prevent this attack.
  • Can you rekey smart locks and electronic deadbolts? Yes. Most smart locks still have a manual override key cylinder for emergencies. We can rekey this mechanical override cylinder just like a traditional deadbolt.

Customer Reviews

"We just bought our first home and wanted to make sure nobody else had a key. They came out the same day we closed, rekeyed all 5 doors to a single key, and charged a very fair price."

"I run a retail store and had to let a manager go. I called them at 6 PM, and they were there by 7 PM to rekey the front doors and the office. Great peace of mind."

"The deadbolt on our front door was constantly jamming. Instead of making me buy a new $150 lock, the technician took it apart, fixed a bent piece inside, and now it works perfectly."
