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.
