Rekeying, smart locks, high-security hardware, and estate key control for San Mateo County homeowners.
A licensed residential locksmith in Portola Valley can rekey your estate home's deadbolts for $60-$120 per lock, install smart locks compatible with Apple HomeKit or Google Home, and set up master-key systems that reduce the number of keys circulating among estate staff and vendors.
Residential locksmiths hold a BSIS license authorizing them to work on home entry hardware: deadbolts, knob sets, lever sets, padlocks, and electronic/smart locks. For Portola Valley estate properties with multiple entry points, detached garages, equestrian outbuildings, and secondary structures, a residential locksmith can build a single master-key system so the property owner carries fewer keys while maintaining access control.
Rekeying changes the internal pin configuration of an existing lock cylinder so that only new keys cut to a different code will operate it. Old keys are voided permanently. The hardware stays in place, making rekeying significantly faster and less expensive than full lock replacement.
When to rekey:
Smart locks are particularly practical for Portola Valley estate properties with regular vendor access. Instead of distributing and recovering physical keys from housekeeping services, landscaping crews, and contractors, a smart lock lets you issue and revoke time-limited entry codes remotely.
Popular smart lock brands compatible with California estate homes include Schlage Encode Plus (supports Apple Home Key, no hub required), Yale Assure Lock 2 (HomeKit and Z-Wave compatible), and August Wi-Fi Smart Lock (retrofit design that preserves existing exterior hardware aesthetics).
Installation typically takes 30-60 minutes. The locksmith will confirm door prep dimensions, install the hardware, configure the initial codes, and walk you through the app pairing process.
Standard residential deadbolts are rated ANSI Grade 2 or Grade 3 and offer adequate security for typical residential use. For Portola Valley estates with higher security requirements, Grade 1 high-security deadbolts from Medeco, Mul-T-Lock, or ASSA Abloy provide additional protection:
High-security hardware costs $80-$300 per lock for the hardware alone, plus installation. The key duplication restriction is particularly valuable for estate properties where multiple vendors have historically had key access.

See our BSIS licensing section for step-by-step verification instructions. Briefly: ask for the BSIS license number before booking, verify it at the California BSIS public portal, and confirm the technician presents photo ID and their license card on arrival.
For estate-scale projects (full property rekey, master-key system setup), ask for a written scope of work before any labor begins listing each entry point, the hardware type at each, and the per-unit cost.
