Fast, Reliable Rekey Locks Across Brentwood
If you’ve just closed on a house in Brentwood, had a roommate move out, or lost track of a spare key, rekeying your locks is the fastest way to restore control of who can get in. Rekeying means we swap the internal pins inside your existing lock cylinders so the old keys stop working and new keys take over – no new hardware required. In most Brentwood neighborhoods, from Deer Ridge to Apple Hill Estates, we can have a technician at your door the same day you call. That includes neighborhoods near Balfour Road, Garin Elementary, and the newer developments east of Highway 4. Call (409) 405-4485 and you’ll get a live person who can give you a straight answer on timing and cost before you hang up.
Why Preston Locksmith & Security Is Brentwood’s Preferred Rekey Locks Company
Brentwood homeowners tend to ask the same three questions before anyone touches a lock: who’s actually showing up, what’s the real price, and how do I know the work is done right. That’s exactly why we built Preston Locksmith & Security around The Relay Visibility Guarantee – a written price before work starts, a live trackable arrival time, and before-and-after photos of every cylinder we repin. Kevin Yoon, who leads our team, has made the rule simple: no anonymous tech, no bill that changes between the quote and the invoice. Every technician is background-checked and arrives in uniform, so when the doorbell rings, you know exactly who you’re letting in.
We do a lot of rekey work in Brentwood’s newer subdivisions where builders installed Kwikset or Schlage deadbolts by default. Those locks are perfectly fine to rekey – we don’t need to sell you new hardware unless the cylinder is genuinely worn out. And we won’t upsell you on a replacement just because rekeying is cheaper. The price we quote on the phone for a Brentwood job is the price on the invoice, period. That’s the standard we’ve held since 2008, and it’s backed by our 365-Day Done Right Promise: if something isn’t right, we come back and make it right at no charge.
Because Brentwood isn’t as dense as Concord or Walnut Creek, scheduling is usually straightforward. A rekey on a typical three-bedroom home with two or three entry doors takes under an hour once we’re on site. And since dispatch and scheduling run through our San Francisco Bay Area office, we typically route a technician to Brentwood the same day you call, often within a couple of hours depending on where you are relative to our current jobs in Contra Costa County.
Keyed Alike in Brentwood
Keyed alike is the phrase we use when every exterior door in your Brentwood home works from a single key. Instead of carrying one key for the front door, another for the garage side entry, and a third for the back patio, one key turns them all. We recently rekeyed the locks at a home in the Deer Ridge neighborhood after a home sale closed. The new owner handed us a mismatched set of old keys for the front door and side garage entry, and our tech pulled the existing Kwikset deadbolts, swapped the pins inside the lock cylinders, and made both doors keyed alike. The old keys stopped working, and we left the owner with two fresh keys and the lock cylinders still in place.
For a Brentwood house with two or three exterior doors on standard Kwikset or Schlage deadbolts, keying the locks alike typically runs $95 to $180 depending on how many cylinders we’re repinning. That’s the total job price, written before we start, with no added service call fee when the tech steps out of the van. If your locks are mismatched brands – say a Baldwin on the front door and a Kwikset on the side – we can often still key them alike if the cylinders accept the same key profile. We’ll confirm that on the phone before you commit to anything.
Single-Key Entry for Busy Families
Most Brentwood households with kids, a dog walker, or a cleaning service prefer one key that works everywhere. It means fewer copies floating around and fewer places for a lost key to cause trouble. We’ll cut you a set of fresh keys on site and test every lock twice before we leave.
Post-Move-In Rekeying
If you bought a resale home in Brentwood and you’re not sure who else might still have a key from the previous owner’s relatives, contractors, or neighbors, rekeying is the fix. We can key all the exterior locks alike as part of the same visit – no need to replace the hardware.
Rekey Deadbolt in Brentwood
A rekey deadbolt job in Brentwood is exactly what it sounds like: we take your existing deadbolt off the door, open the cylinder, swap the tiny spring-loaded pins inside, and put the deadbolt back. Your old keys stop working immediately. The deadbolt itself – the housing, the bolt, the thumbturn – stays right where it is. In most Brentwood homes built after the early 2000s, the deadbolts are builder-grade Kwikset or Schlage units that were installed by the original contractor. Those cylinders almost always repin cleanly on the first visit.
Rekeying a standard deadbolt in Brentwood runs $35 to $55 per cylinder, and most homes have two or three exterior deadbolts. If you’ve got a Baldwin or Yale deadbolt with a higher-security cylinder, the work is the same but the per-cylinder price can run $55 to $75 because the pins and tolerances are tighter. We’ll give you the exact per-cylinder price over the phone before anyone rolls out – no range games.
Worn-Out Deadbolt Cylinders
Occasionally a deadbolt on a Brentwood home has been in service for 15-plus years and the pins inside wear down enough that rekeying won’t hold reliably. When that happens, we’ll show you the cylinder and explain a direct replacement as an option. We won’t do the replacement without your okay, and the 365-Day Done Right Promise covers new hardware we install too.
Same-Day Deadbolt Rekey
Since we stock rekey kits and replacement pins for Kwikset, Schlage, and Yale on our service vehicles, there’s no run back to a supply shop for a typical Brentwood job. That’s why most same-day calls get finished the same afternoon they’re booked.
Trusted Brands We Service in Brentwood
Most Brentwood homes have Kwikset or Schlage deadbolts and knobs on the exterior, and that’s where most of our rekey work starts. But we’re also factory-trained on Medeco, Baldwin, Yale, and Mul-T-Lock hardware, which matters if you’ve upgraded to high-security cylinders or if your home has a front entry set from a premium builder. Because our techs carry rekey kits and pins for all those brands on the truck, we don’t have to schedule a second visit for a “special order” part on a Brentwood job. If you’re not sure what brand your lock is, read the face of the deadbolt or the edge of the bolt itself – it’s usually stamped right there, and we can confirm it with you over the phone.
Common Rekey Locks Problems We See in Brentwood Homes
- Surprise service-call fees after a low phone quote. Homeowners in Brentwood accept a phone quote that sounds low, then get an added “service call” or “after-hours” surcharge when the tech arrives. We fix this by putting the full price in writing before anyone is dispatched, and no one shows up at your door with a surprise line item.
- Worn builder-grade deadbolts that refuse a clean rekey. A rekey is attempted on a tired Kwikset or Schlage cylinder, but the pins won’t seat reliably because of years of dust, grit, and spring fatigue. When that happens in Brentwood, we’ll show you the cylinder and discuss a direct replacement rather than leave you with a lock that works only sometimes.
- Unverifiable techs at the door. A homeowner opens the door to someone who can’t or won’t prove they’re from the company that was called. Every Preston tech arrives in uniform, is background-checked, and can show you their ID and your written job order before they touch a lock.
- Post-sale key control gaps. New owners in Brentwood’s resale market sometimes wait weeks or months before rekeying, which means all the old keys are still out in the world. We’ve rekeyed plenty of houses on Lone Tree Way and around Veterans Park where the previous owner’s keys had circulated among multiple people without anyone keeping a count.

FAQs About Rekey Locks in Brentwood
Every Preston Locksmith & Security technician arrives in a marked uniform with a photo ID badge and a printed copy of your written job order. The written price we agreed on over the phone is on that order, so you can compare it with what’s in your text or email before we start. You’ll also get a live trackable arrival time, so you see who’s coming and when – before they knock. If anything ever looks off, call (409) 405-4485 and we’ll verify with you on the spot.
Yes. Brentwood’s housing stock is full of builder-grade Kwikset and Schlage deadbolts, and those cylinders rekey cleanly in the vast majority of cases. We just replace the pins inside the cylinder and cut you new keys. The only reason you’d need a new deadbolt is if the cylinder is mechanically worn or corroded to the point where new pins won’t seat reliably, and we’ll only suggest that if we can show you the problem clearly. Call (409) 405-4485 for a phone quote on your specific locks.
No. Our per-cylinder rekey prices are the same across our Contra Costa County service area, including Oakley, Discovery Bay, and Antioch. What changes from job to job is the number of locks and the brand of hardware, not the city line you live on. We won’t tack on a “Brentwood surcharge” or an “after-hours fee” for a normal same-day job. The price you get on the phone is the final number.
For a standard three-bedroom Brentwood home with two or three exterior doors on Kwikset or Schlage deadbolts, the on-site work takes 30 to 60 minutes. That includes pulling each cylinder, swapping the pins, testing the new keys, and cleaning up. You don’t need to empty the house or move furniture – it’s just the door hardware. If you’re on a tight schedule, call (409) 405-4485 and we’ll give you a live arrival window before you commit.
We can still help, but the job and the price are a little different. Mortise locks, common on some older or custom-built Brentwood homes, have a larger body inside the door and require a different cylinder removal process. Smart locks with a key override can often be rekeyed at the cylinder like any other deadbolt, but some integrated electronic models need a factory reset or a cylinder swap. Tell us what you have over the phone – we’ll walk you through what’s possible and what it costs before we schedule the visit. Reach us at (409) 405-4485.
