Fast, Reliable Rekey Locks Across Lucas Valley-Marinwood
Rekeying locks in Lucas Valley-Marinwood typically costs $25 – $45 per cylinder and takes under an hour for most homes. The work means swapping the internal pins so old keys stop working while your existing hardware stays in place. If you’ve just bought a house off Lucas Valley Road, lost a key in Marinwood, or have a former tenant or contractor who might still have copies, call us at (409) 405-4485 and we’ll give you a written price before anyone gets in the truck.
We know this area’s homes well because we work in them every week. Lucas Valley-Marinwood isn’t one housing style stacked next to another. It’s 1960s ranch homes along Lucas Valley Road, two-story tracts from the 1970s and 1980s in Marinwood proper, and a handful of newer builds tucked up against the open space. That mix matters when you’re rekeying locks, and we plan for it before we arrive.
Why Preston Locksmith & Security Is Lucas Valley-Marinwood’s Preferred Rekey Locks Company
Kevin Yoon founded Preston Locksmith & Security in 2008, and the way we run rekey jobs hasn’t changed since: a written price before work starts, a live arrival time you can track, and before-and-after photos of every cylinder we touch. No other locksmith serving Lucas Valley-Marinwood puts that in writing. That’s The Relay Visibility Guarantee, and it’s on every invoice.
When a Marinwood homeowner calls about a rekey, they’re usually handling something time-sensitive. A closing date that moved up. A key that went missing somewhere between the car and the front door. A roommate situation that ended on bad terms. We answer the phone 24 hours a day with a live person. No voicemail queue, no callback tag. You’ll know the price, the arrival window, and the name of the background-checked, uniformed technician before they knock.
Our Rekey Locks team carries pinning kits for Schlage, Kwikset, Medeco, and Baldwin hardware, which covers nearly every lock we encounter in Lucas Valley-Marinwood. That means we don’t leave mid-job to chase a part. We also know which homes in this area tend to have original 1960s cylinders that need different pinning than the newer deadbolt someone added years later. That’s not something a generic locksmith from outside the area figures out on the fly. It’s something we already know when we quote the price.
Keyed Alike in Lucas Valley-Marinwood
Keyed alike means setting multiple locks to open with the same key, and in Lucas Valley-Marinwood it’s one of our most common requests. A typical keyed-alike job across three or four exterior doors runs $95 – $180 total, including the pinning work and a written key count. Homeowners ask for it when they’re tired of a key ring with four nearly identical brass keys, or when they’ve bought a home and want every door on one new key while making every old key useless.
The catch in this area is the mixed-vintage hardware. A home off Lucas Valley Road might have a 1960s Kwikset knob on the garage door, a newer Schlage deadbolt on the front, and a Baldwin handle on the side entrance. Getting all of them keyed alike isn’t just about cutting the same key. It requires pinning each cylinder to match a single pinning chart, and the older cylinders often need different bottom pins than the newer ones. We do that consistently, and we check every cylinder after pinning to confirm the old keys no longer turn.
Single-Key Conversion
Most Lucas Valley-Marinwood homes have three to five exterior locks. Converting them all to one key takes about 45 to 90 minutes depending on how many cylinders we’re repinning and whether any are worn past the point of holding a new pin stack. We quote the full job before dispatch, not a per-hour estimate that climbs once we see the hardware.
Old Key Retirement
When we key locks alike, every previous key is retired. We test each lock with the old key to prove it no longer operates, then we hand you all the new keys and bag the old ones for disposal. You’ll get a written key count so you know exactly how many copies exist.
Rekey Deadbolt in Lucas Valley-Marinwood
Rekey deadbolts in Lucas Valley-Marinwood usually run $30 – $50 per deadbolt, and the job takes about 15 to 25 minutes per lock. The deadbolt is the lock that actually secures the door against forced entry, so it’s the one homeowners care about most. We rekey the cylinder so the old key stops working, then we check the strike plate, the bolt throw, and the fit of the door to make sure the deadbolt is doing its job.
In older Marinwood homes we frequently see deadbolts that were added years after the original construction, which means the cylinder is newer than the doorknob below it. That’s fine mechanically, but it means a single-door rekey often involves two different pinning kits. We account for that in the quote, so the price you get on the phone is the price on the invoice. There is no dispatch fee added on arrival and no bait price that swells once the tool bag opens.
Deadbolt Health Check
Every deadbolt rekey includes a quick physical check. We look for a strike plate that’s loose, a bolt that doesn’t fully throw, or a cylinder that’s so worn the pins float. If the rekey won’t hold because the cylinder is past saving, we tell you before we do the work and give you a straight replacement price.
Mixed-Brand Front Door
A front door with a Schlage deadbolt above a Kwikset knob is standard in Lucas Valley-Marinwood, and it’s honestly not a problem. We pin both cylinders to the same key during the visit. What matters is that both get pinned from the same key control plan, not with whatever pins are closest in the van. That’s how you avoid a deadbolt that works with the new key while the knob still turns with the old one.
Trusted Brands We Service in Lucas Valley-Marinwood
We’re trained and equipped to service Schlage, Kwikset, and Medeco hardware, plus Abloy, Baldwin, Mul-T-Lock, Yale, and Sargent cylinders. For Lucas Valley-Marinwood customers, that matters because this area’s housing stock runs heavily toward original Kwikset and Schlage from the 1960s through the 1980s, with Medeco and Baldwin showing up on higher-end upgrades. We keep a full range of OEM pinning kits in the truck, so a rekey on a Medeco high-security cylinder doesn’t turn into a two-day wait for parts. If your lock uses a brand we can’t properly pin, we tell you before we quote, not after we’ve taken the lock apart.
Common Rekey Locks Problems We See in Lucas Valley-Marinwood Homes
- Float pins in worn 1960s cylinders. Original builder-grade Kwikset cylinders in the oldest Lucas Valley Road homes often have enough wear that a standard rekey won’t hold. The old key can still jiggle the pins and turn the plug weeks later. We check for this before we call the job done.
- Mixed-vintage hardware on the same door. A newer Schlage deadbolt above a 1960s Kwikset knob is not unusual in Marinwood. Both need pinning, but they take different kits. We quote for both before dispatch so the price doesn’t change at the doorstep.
- Missing keys after a property transfer. When a Lucas Valley-Marinwood home changes hands, the seller sometimes hands over one key that works the front door and shrugs at the rest. We can rekey every exterior lock to one new key and give you a written key count in the same visit.
- Mortise locks on older front doors. Some ranch homes off Lucas Valley Road still have original mortise locks, and those don’t rekey the same way as bored cylindrical locks. We tell you what the job involves before quoting, including whether the mortise body should be replaced rather than repinned.

FAQs About Rekey Locks in Lucas Valley-Marinwood
In nearly every case, rekeying is the right call and it costs $25 – $45 per cylinder instead of $60 – $150 per new lock. Rekeying swaps the internal pins so every previous key stops working, which is what you actually need after a sale closes. Replacement only makes sense if the hardware is physically damaged or you want to upgrade to higher-security cylinders. Call (409) 405-4485 and we’ll tell you which applies after we look at the locks.
Yes, and this is a standard job for us in Marinwood. A home with a 1960s Kwikset knob on the back door and a Schlage deadbolt up front can absolutely be keyed alike. We pin each cylinder to the same key control plan using the correct pinning kit for each brand, then we test every lock with the old keys to confirm they no longer turn. The quote covers the mixed-brand work before we arrive.
You’ll get the technician’s name, photo, and a live trackable arrival time before they reach Lucas Valley-Marinwood. Our techs arrive in uniform, drive marked vehicles, and carry company identification. The Relay Visibility Guarantee also means you get before-and-after photos of every cylinder we touch, so there’s a record of exactly what was done and who did it. Kevin Yoon’s team has worked this way since 2008.
A full rekey on a three- or four-door Lucas Valley-Marinwood home takes 45 to 90 minutes. Single deadbolts run about 15 to 25 minutes each. Older cylinders with float-prone pins or mortise locks on the front door can add time, but we tell you that during the quote, not after we’ve started.
No, a properly done rekey doesn’t damage the lock and doesn’t void the manufacturer’s warranty. The cylinder is disassembled, the old pins are replaced with new ones matched to your new key, and everything is reassembled with the same components. If a cylinder is too worn to hold a rekey properly, we stop and show you before recommending a replacement. Every job is covered by our 365-Day Done Right Promise, and if a rekey fails within a year, the second visit is free.
