Which Should You Choose for Your San Carlos Home?

Most new San Carlos homeowners ask whether to rekey or fully replace their locks. The answer depends on the condition and age of the existing hardware.

  • Rekey when: hardware is in good condition, 5 years old or newer, you just want old keys deactivated
  • Replace when: hardware is worn, damaged, or low-grade (Grade 3 builder locks)
  • Upgrade to Grade 1 deadbolt when: buying a home with original 1970s-1990s hardware
  • Smart lock when: you want keypad access, rental guest codes, or remote unlock capability
San Carlos homes tip: Many White Oaks and Beverly Terrace homes were built in the 1950s-1970s. Original lock cylinders may no longer meet Grade 1 standards. Ask the locksmith to assess the hardware during the service call.
