Rekeying changes the internal keying so an old key no longer works while the existing lock body stays in place. Cylinder replacement changes the key-operated core. Full lock replacement changes more of the hardware. The right option depends on condition, compatibility, desired security and whether you want several doors to work with one key.
Common reasons to rekey
Moving into a property, changing tenants, losing control of key copies or simplifying a set of doors are common reasons. HSI Locksmith provides rekeying, cylinder replacement and lock installation in Boca Raton, Delray Beach, Boynton Beach and across Palm Beach County.
