Why Novak Lock & Security Is Concord’s Preferred Lock Installation & Rekey Company
Concord homeowners call us because we show up knowing the city’s housing stock. The ranch homes near Clayton Road, the garden apartments along Monument Boulevard, the condos by Todos Santos Plaza: each building type has predictable lock failures, and we have seen them thousands of times. Our technicians are background-checked and uniformed, and every visit ends with a documented photo record left with the customer. That is not a courtesy. It is procedure.
We answer the phone with a live person, 24/7. When a deadbolt seizes on a 100-degree afternoon in a house off Treat Boulevard, you do not want a voicemail queue. You want a dispatcher who can name a price and a technician who can be there quickly. Concord sits deep in the inland Diablo Valley, and we stage local crews who understand that summer heat means swollen wood frames and stuck bolts. Our written estimate covers the work, the hardware, and the documentation. No arrival surcharges. No bait-and-switch.
Since 2002, we have installed or serviced more than 60,000 locks, keys, and systems across the East Bay, including Lock Installation & Rekey in Concord. Every one of those jobs carried a written price before the first tool came out.

Smart Lock Installation
Concord homeowners in 1960s ranch homes are increasingly replacing original deadbolts with smart locks for keyless entry and remote access. The important detail in Concord is frame compatibility: if the original wood frame has swelled or shifted over 50 Diablo Valley summers, the smart lock’s bolt will bind in the strike plate. We inspect the frame alignment before installing any smart lock, and we will tell you plainly if the door needs strike plate adjustment or frame work first. A typical smart lock install in Concord runs $180-$350 including hardware mounting and app setup, quoted in writing.

Keyless Entry
Keyless entry systems for Concord condos and apartments turn on the same principle: a code replaces a key, and when a tenant moves out, you delete the code instead of rekeying the building. For owners of rental units near the Concord BART station, that eliminates the key-control problem that otherwise forces building-wide rekeys. We install standalone keypad deadbolts and full keyless entry systems for multi-tenant entry doors. Keyless entry installation in Concord typically runs $150-$320 per door, depending on the system and whether door frame work is needed.

Keypad Lock
A keypad lock is the most common entry-level upgrade on Concord’s apartment and condo units, especially where a freeholder or HOA has rules about drilling into doors. Keypad locks give you keyless entry without a full smart home integration. We install keypad deadbolts and lever sets from Schlage, Kwikset, and Baldwin, and we will match the finish to the existing hardware. In Concord, keypad lock installation runs $120-$280 per door, with the price quoted in writing before we start.

Biometric Lock
Biometric locks, typically fingerprint readers, show up most in Concord home offices, gun safes, and a few high-end residential entries in neighborhoods like Holbrook and Turtle Creek. They are not the right choice for every door, and we will say so if your door frame will not hold alignment. Biometric lock installation starts around $250 and can run to $500 or more depending on the cylinder grade. We recommend a physical key override on any biometric install; being locked out by a dead battery at midnight is avoidable.

Common Lock Installation & Rekey Problems We See in Concord Homes

- Seized deadbolts on summer days. The Diablo Valley’s 95-105°F heat swells the original wood door frames on Concord’s 1960s-1970s ranch homes, squeezing the deadbolt against the strike plate until the key will not turn. We see this every June through September, especially on homes off Clayton Road, Bailey Road, and around the Monument Corridor.
- Original hardware on 50-year-old doors. Many Concord tract homes still run their first-generation deadbolts, which are not bump-resistant and do not meet current California entry security standards. Homeowners who buy a rental or inherited home often rekey or replace these locks on day one.
- Key-control gaps in rental turnover. Apartment complexes near the Concord BART station and along Monument Boulevard run high tenant turnover, and unreturned keys mean no one knows who holds a working key to the building. Building-wide rekeys under time pressure are the normal fix.
- Bent strike plates from Diablo wind. Winter wind events in the Diablo Valley can slam doors hard enough to bend strike plates and damage latch hardware on older, lighter-gauge doors. A bent strike plate makes even a good lock feel misaligned and stiff.
Pricing for Lock Installation & Rekey in Concord, CA
Here are the ranges we quote for Concord work. Rekeying a standard residential cylinder runs $65-$95 per cylinder, including disassembly, new pins, and a new key. Rekeying to a restricted keyway, common in Concord apartment buildings, runs $120-$185 per cylinder because the key blank itself is restricted and cannot be copied at a hardware store. New deadbolt installation runs $120-$280, and full lock replacement with a Grade 1 deadbolt runs $180-$380 depending on door prep. Key duplication for standard keys is $5-$12 per key; restricted keys from Mul-T-Lock or Abloy run $18-$35 each. Every quote is written before we dispatch, and the technician cannot change it at the door. Call (331) 310-8471 and ask for Daniel Novak’s team; estimates are free.

FAQs - Lock Installation & Rekey in Concord

A deadbolt that sticks in summer is almost always the wood frame swelling, not the lock cylinder failing. Concord’s 1960s-1970s ranch homes were built with original wood door frames that absorb heat and moisture, and the inland Diablo Valley regularly hits 95-105°F, far hotter than coastal Bay Area cities over the hills. The swollen wood pushes the door out of alignment and squeezes the bolt against the strike plate. The fix is strike plate realignment or minor frame adjustment, not replacing the entire lock. Our techs perform this adjustment without drilling or damaging the freeholder’s door. Call (331) 310-8471 for a written quote; we can usually reach Concord homes the same day.
Yes. We rekey the existing lock cylinders by replacing the internal pins, so the hardware stays in place and the old keys stop working. For a multi-tenant building, that means all common-area Schlage deadbolts can be changed to a new restricted keyway in one visit, without replacing the hardware itself. We rekeyed a six-unit complex off Monument Boulevard last June that way, after a tenant moved out and the property manager could not account for all the old keys. A building-wide rekey typically runs $65-$155 per cylinder depending on whether you choose a standard or restricted keyway, quoted in writing before we start. Call (331) 310-8471 to schedule a survey.
California law permits a landlord to deduct the cost of a rekey from a security deposit only if the rekey is necessary to restore the unit to the condition it was in at move-in, and only if the tenant caused the need by losing keys or failing to return them. A routine rekey between tenants is generally considered a normal turnover cost, not a tenant charge. If you are a Concord tenant and your landlord is charging you for a rekey you did not cause, request a written itemization. If the charge stands, call us at (331) 310-8471 and we will give you a written copy of the rekey cost so you can compare it fairly. Estimates are free.
Install an ANSI Grade 1 deadbolt with a reinforced strike plate and a cylinder that carries at least a bump-resistant rating. The bolt should be solid metal, not the hollow bolt common on budget deadbolts, because solid bolts tolerate frame movement better. We also recommend replacing the original wood strike plate screws with longer screws that anchor into the frame stud, which reduces shifting as the wood swells. In Concord, a Grade 1 deadbolt installation runs $180-$380, including door prep and strike plate reinforcement, quoted in writing before we start. Call (331) 310-8471 and we will tell you exactly what your 1968 door needs.
Yes, in most cases. We use non-destructive entry techniques, including lock picking with professional tools, to open a locked condo door without drilling the cylinder or damaging the door, which matters when the door is not yours to alter. If you are a tenant or a condo owner with HOA rules about door hardware, we document the entry with a photo record so there is a clear written record that no damage occurred. The price is quoted on the phone, typically $95-$220 depending on the lock type, and it is the price on the invoice. Call (331) 310-8471 and we will get you back in without putting a hole in a door the freeholder owns.
