We recently rekeyed a 1970s custom estate on a sloped lot near Newport Avenue and La Colina Drive where the owner wanted high-security Mul-T-Lock cylinders on the main entry, detached garage, and pool gate - all keyed to a single master system. The original Schlage strikes were corroded from hard water and sun exposure, causing deadbolt binding; we reinforced the frames and retrofitted proper strike plates to eliminate the misalignment. Jobs like this are why we stock premium hardware and keep experienced technicians on the road.
Our Lock Installation & Rekey Services in North Tustin
Smart Lock Installation
North Tustin’s large custom homes with multiple entry points - primary doors, side entrances, detached garages, pool houses - benefit from smart lock systems that eliminate key management headaches. We install Schlage Encode, Yale Assure, and other Wi-Fi and Z-Wave options that integrate with existing home automation. Because North Tustin is unincorporated Orange County, smart lock installation for ADUs or major security upgrades may require county permitting rather than city approval. We help you navigate that distinction so your project doesn’t stall.
Electronic Lock & Keypad Entry
Keypad locks are popular on North Tustin’s wrought-iron driveway gates and service entrances, where carrying a physical key to a gate fifty yards from the house is impractical. We install weather-rated electronic keypads from Schlage and Kwikset that withstand the sharper temperature swings and Santa Ana wind grit common in the foothills. Many hillside homes here have gates exposed to direct sun and chaparral debris; we specify hardware with sealed keypads and stainless-steel components to prevent the intermittent failures we see every autumn.
Biometric Lock Installation
For North Tustin’s estate properties, biometric fingerprint locks offer access control without code sharing or key duplication. We install these on wine rooms, home offices, and secondary structures where selective access matters. Fingerprint readers require precise alignment and clean power; we verify your door frame condition first, because a biometric lock on a loose frame from the 1970s will fail regardless of the technology’s quality.
Key Duplication
We cut keys on-site for Medeco, Mul-T-Lock, Schlage, Kwikset, and high-security restricted keyways. North Tustin’s master-key systems - common on multi-structure estates - require precision duplication that hardware store kiosks can’t provide. We verify each key against the lock before leaving. Our mobile units carry blanks for most premium brands, so you’re not waiting for a special order.

Common Lock Installation & Rekey Problems We See in North Tustin Homes
- Original 1960s-80s Schlage or Kwikset interior knobs with worn springs that fail completely during a rekey, requiring full replacement to match the new keyway. The spring tension in these vintage knobs degrades predictably after forty-plus years; we test before we start so you’re not surprised by a parts upgrade mid-job.
- Corroded strike plates and loose door frames from decades of coastal foothills humidity and Santa Ana winds causing deadbolt bind even after new cylinders are installed. Rekeying or replacing the lock won’t fix a frame that’s shifted on its hinges. We check alignment as standard practice.
- Homeowners mistakenly referencing Tustin city code instead of Orange County permitting for smart lock installation, delaying projects until the correct jurisdiction is confirmed. North Tustin is unincorporated - your permit comes from the county, not the city. We clarify this on the first call so your timeline stays intact.
- Seasonal binding from thermal expansion in the inland foothills, where sharper day-to-night temperature swings than coastal Orange County cause metal door frames and lock cylinders to expand and contract. Your deadbolt that worked fine in June may stick in October. We identify expansion-related binding and specify hardware with tighter tolerances where needed.

FAQs - Lock Installation & Rekey in North Tustin
No - standard rekeying does not require any permit in unincorporated Orange County. Permits only enter the picture for new electronic access systems, ADU security installations, or structural modifications to door frames. Because North Tustin is unincorporated, any required permitting routes through Orange County rather than the City of Tustin. Call (833) 294-4584 and we’ll confirm whether your specific project needs paperwork.
Santa Ana wind events drive fine grit and chaparral debris into exterior keyways, and the sharper temperature swings of North Tustin’s foothill position cause metal frames to contract differently than in summer. The combination produces seasonal binding that eases in milder weather. We clean and lubricate cylinders properly - not with graphite that attracts more grit - and check frame alignment. Call (833) 294-4584 before the winds pick up.
Yes, provided the hardware is compatible. We regularly master-key North Tustin estates with multiple structures, matching Mul-T-Lock, Medeco, or high-security Schlage cylinders across primary entries, detached garages, pool gates, and service entrances. We assess each lock’s condition first; corroded strikes or loose frames must be addressed or the new keying won’t operate smoothly. Call (833) 294-4584 for an exact quote on your property.
No - a freely spinning knob indicates a failed internal spring or cam, not just a keyway issue. Rekeying won’t restore function; the knob needs replacement. We carry period-appropriate Schlage and Kwikset replacements that match your existing finish and keying. Done right, and backed in writing. Call (833) 294-4584 to schedule.
Yes - we install and repair electronic keypads, mechanical deadbolts, and padlock hardware on North Tustin’s wrought-iron and ornamental gates. We specify weather-sealed components because these gates take direct sun, wind grit, and occasional moisture with no protection. Call (833) 294-4584 for a free estimate.
