Lock Installation & Rekey in Placentia: Direct Answer
Lock rekeying in Placentia typically costs $25-$45 per cylinder, and a standard deadbolt installation runs $95-$180 including hardware and labor. Most single-family homes here need 3-5 cylinders rekeyed, so a full post-sale rekey usually lands between $120-$250 total. We quote the complete price on the phone before anyone is dispatched, and that price does not change when the technician arrives. That rule has been in place since 2002, and it is the foundation our business is built on. Call (331) 310-8471 for an exact quote on your Placentia home.
Fast, Reliable Lock Installation & Rekey Across Placentia
Novak Lock & Security handles Lock Installation & Rekey work across Placentia, from the ranch-style tracts off Yorba Linda Boulevard to the older bungalows near Bradford Avenue. We know Placentia’s housing stock: the dominant pattern is 1960s-1970s single-family detached homes built as the orange groves were subdivided, with original wood door frames that have been swelling and contracting for five decades. That matters when you’re aligning a deadbolt or fitting a smart lock. Our technicians are background-checked, uniformed, and arrive with a written scope and a photo-documented record of every visit as standard.

Why Novak Lock & Security Is Placentia’s Preferred Lock Installation & Rekey Company

Since 2002, we’ve installed and serviced more than 60,000 locks, keys, and systems across Orange County, every one with a written price before we started and a documented record when we left. Placentia customers consistently tell us the same thing: they researched, they read reviews, and they called us because the price was visible and the process was written down. There are no call-out surcharges added at the door. No bait pricing. The dispatcher gives you a firm number, and the technician is contractually bound to honor it under Haven Standard Clause 1: the price on the phone is the price on the invoice.
Placentia’s mix of 50-60-year-old tract homes and aging original hardware means we see specific problems repeat: worn Kwikset pin-tumbler cylinders that spin freely, deadbolts that bind each fall when Santa Ana winds dry out the wooden jambs, and aluminum screen-and-security doors with non-standard 1-3/8″ door prep that most replacement cartridges cannot fit. We carry the right backset hardware and step-drill jigs for those doors, and we’ve done enough of them in Placentia to know what we’re walking into before we arrive. Daniel Novak, our owner, personally oversees the training on these legacy-home retrofits.
Our Lock Installation & Rekey Services in Placentia
Smart Lock Installation
Placentia homes built in the 1960s and 1970s have solid wood doors in most cases, but the aluminum screen-and-security doors on the front entries complicate smart lock retrofits. We install smart locks from Schlage, Yale, and Baldwin, and we handle the backset conversion on thinner doors so the deadbolt actually seats. A smart lock installation on a standard 1-3/4″ Placentia door runs $220-$400 including hardware; expect the higher end if we’re retrofitting an aluminum screen door alongside it.

Keyless Entry
Keyless entry works well for Placentia’s ranch-style homes, especially when owners want separate access for an outbuilding, pool gate, or detached garage. We install keypad and fob-based entry systems that integrate with existing deadbolts or replace them entirely. Pricing for keyless entry hardware and installation in Placentia runs $180-$450 per door, quoted in writing before we start.

Keypad Lock
Keypad locks are the most common request we get from Placentia homeowners with 1960s-era tract houses. The old Kwikset hardware is tired, and owners want a code instead of a key. We stock Schlage keypad deadbolts and Yale keypad locks locally, so most keypad installations in Placentia are completed the same day the call is placed. Typical cost: $160-$320 per lock installed.

Biometric Lock
Biometric locks (fingerprint and key-fob hybrid systems) are installed more often on Placentia homes with detached workshops or gates, where owners want to control access without carrying keys to a building 200 feet away. We install biometric hardware from Yale and other premium brands, and the installation typically runs $350-$600 per lock depending on the door prep and wiring.

Key Duplication
We duplicate standard house keys at our mobile service units, and we cut high-security keys from Medeco and Mul-T-Lock. If you purchased a Placentia tract home and have no idea how many copies of the original key are floating around, rekeying is the better move. Key duplication alone starts at $5 per key for standard cuts, and high-security keys are priced by the card system.

Trusted Brands We Service in Placentia

We are factory-authorized to install and service Medeco, Mul-T-Lock, Yale, and Baldwin hardware, and we work daily with Schlage and Kwikset. For Placentia customers, that means we stock replacement cylinders, backset plates, and tailpieces locally rather than ordering parts and leaving a door torn apart for a week. If your existing hardware is from any of those brands, we can rekey it, rebuild it, or replace it with a compatible upgrade, all priced in writing before we touch anything.
Common Lock Installation & Rekey Problems We See in Placentia Homes
- Worn original Kwikset cylinders on 1960s tract homes. The pin-and-tumbler hardware on Placentia’s original ranch houses is now 50-60 years old. After tens of thousands of cycles, the cylinder walls wear enough that new rekey pins will not seat reliably, and the lock fails intermittently. In most cases, we recommend full replacement with ANSI Grade 1 or Grade 2 hardware rather than rekeying a cylinder that’s already failing.
- Aluminum screen-and-security doors with non-standard 1-3/8″ door prep. A notable share of Placentia’s 1960s-70s tract homes have combination aluminum screen-and-security doors. Modern deadbolt cartridges are cut for 1-3/4″ doors. If a locksmith doesn’t carry the right backset plates and a step-drill jig, the cartridge cannot be secured, or worse, they bore through the door face. We carry the correct hardware for Placentia’s specific door thickness.
- Seasonal deadbolt binding during Santa Ana wind events. Placentia’s inland position puts it directly in the path of Santa Ana winds, which are hotter and drier here than in coastal Orange County. The rapid humidity drop causes wooden door jambs on 1960s tract homes to contract and shift. Older deadbolt bolts that were always tight suddenly bind, and homeowners force the key until the strike plate pulls out or the cylinder breaks. This is a jamb alignment problem, not a lock problem, and we correct it at the jamb, not by grinding down the bolt.
- Self-rekeyed outbuildings and gates failing intermittently. Placentia has a number of acreage remnants and larger lots where owners added outbuildings, workshops, and roadside gates decades ago. We regularly see big-box rekey kits used on these, with pins that will not seat in worn original Kwikset cylinders. The result is a gate or workshop lock that works sometimes and not others. When we come in, we either replace the cylinder or rebuild the lock so every key turns with certainty.

FAQs - Lock Installation & Rekey in Placentia
Most original Kwikset pin-and-tumbler cylinders on 1960s and 1970s Placentia homes are too worn to rekey reliably, so replacement is usually required. We assess each cylinder on site: if the keyway is sloppy or the pins will not seat cleanly, a rekey will leave you with a lock that works intermittently. Replacement hardware typically runs $95-$180 per door, installed with a written quote before we begin. Call (331) 310-8471 and we’ll tell you over the phone whether your locks are likely candidates for rekey or replacement.
No, in most cases we can retrofit the existing door using a 1-3/8″ backset adapter and a step-drill jig, provided the aluminum door frame is structurally sound. The issue is that modern deadbolt cartridges are cut for 1-3/4″ doors, and locksmiths who don’t carry the right backset hardware cannot complete the install. We carry that hardware on every Placentia service call and can typically install a new deadbolt on your aluminum screen door for $140-$250. Call (331) 310-8471 with the door’s width and current hardware and we’ll quote you directly.
Yes, we key every lock on the property alike in a single visit, including the house, outbuilding, workshop, and roadside gate. We carry pin kits and cylinders in the van, so we don’t have to return with parts. For Placentia properties with multiple structures and gates, we typically recommend a master key system so you have one key that works everything, and the ability to issue restricted keys for specific buildings if ever needed. Pricing depends on the number of cylinders, and it’s quoted in writing before any work starts. Call (331) 310-8471 for a specific number.
It’s almost always a door jamb problem, not a lock problem. Placentia’s inland Orange County position means hotter, drier Santa Ana winds that rapidly contract the wood in your 1960s-era door frame. The jamb shifts, the deadbolt bolt binds against the strike plate, and forced turning damages the cylinder or pulls the plate loose. We realign the jamb, reset the strike plate, and test the throw across temperature swings so the deadbolt works in every season. A realignment call in Placentia typically runs $120-$200. Call (331) 310-8471 and we’ll schedule it before the next wind event.
Yes, and we do it regularly. The main challenge is the aluminum screen-and-security door, which uses a non-standard 1-3/8″ door prep, and we carry the backset adapters and step-drill jigs required to install a smart lock deadbolt on that thinner prep. The wooden entry door behind it is usually a standard 1-3/4″ door and accepts smart lock hardware without issue. Smart lock installation on a Placentia home with both door types typically runs $220-$400 total. Call (331) 310-8471 for an exact quote based on your specific doors and smart lock model.
One Visit, Every Door Keyed Alike - Across Placentia

Placentia’s 1960s and 1970s tract homes were built when a single key for a single deadbolt was enough. What we find now, house after house, is a property that has grown: a detached workshop, a roadside gate, a pool enclosure, a screen-and-security door with non-standard hardware. Each lock was added at a different time, with a different key. Last month our crew serviced three exterior doors on a ranch-style home off Alta Vista Street, a 50-year-old tract house whose original Kwikset pin-and-tumbler locks were so worn the key cylinders spun freely. Because the owners had added an outbuilding and a roadside gate in the decades since, we replaced all hardware with ANSI Grade 1 deadbolts, transferred the pins to a single master key system, and retrofitted two original aluminum screen doors with 1-3/8″ backset deadbolts: one visit, every door keyed alike.
That is the work we do across Placentia. The non-standard door prep on those aluminum security doors is the thing that separates a locksmith who finishes the job from one who leaves the door torn apart. We carry the right hardware, we write down the price before we start, and we document what we found when we leave. Daniel Novak built this company on that discipline in 2002, and it holds on every call in Placentia.
