Fast, Reliable Rekey Locks Across Concord
Rekeying a lock in Concord typically costs $75 – $160 per cylinder for labor, plus $5 – $35 if we supply new keys, and most single-family home jobs are done in 45 – 90 minutes. A rekey means we swap the internal pins inside your existing lock so old keys stop working and a fresh key takes over. No new hardware needed. If someone moved out of your Concord home, lost a key, or you just closed on a house near Concord Blvd, call (409) 405-4485 and we’ll give you a written price before anyone is dispatched.
Why Preston Locksmith & Security Is Concord’s Preferred Rekey Locks Company
We’ve handled rekey jobs in Concord since Preston Locksmith & Security was founded in 2008, and the work here has its own rhythm. Older ranch tracts, newer builds near the Concord BART station, rentals turning over every year or two. Concord homeowners and landlords call us because the price is locked in writing before we roll, and the technician who shows up is background-checked and in uniform. You see a live trackable arrival time the moment your job is booked, so there’s no four-hour window.
Kevin Yoon leads our rekey work across the Concord area, and the standard we hold is the same on every job: written price, before-and-after photos, and the 365-Day Done Right Promise. If it’s not done right, we make it right, with a written guarantee stamped on every repair. Landlords near Todos Santos and homeowners off Clayton Road both get the same thing: a real person answering the phone 24/7, no voicemail trees, no callback queues.
Rekey Deadbolt in Concord
Rekey Deadbolt work in Concord is the most common service we do, and it usually runs $75 – $150 per deadbolt depending on the cylinder type and key style. The process means disassembling the deadbolt cylinder, replacing the internal pin and tumbler stack, and reassembling it so the old key no longer turns. No new deadbolt is installed, and the lock stays on your door.
Why Concord Deadbolts Need More Than a Pin Swap
Many Concord homes built in the 1950s and 1960s still run the original Schlage or Kwikset deadbolts. Contra Costa’s dry-summer heat hardens the factory grease inside those cylinders. Before we rekey, we clean the plug and re-lubricate it, so the new pins ride smooth instead of hanging up six weeks later.
When a Landlord or New Homeowner Should Rekey
Right after a tenant moves out, right after closing, or right after a key goes missing. If you’re near the Concord BART station and renting a unit, rekeying the deadbolt between tenants is the single fastest way to cut off access from whoever has the old key. We can key it to a master key system so you keep one key for every unit while tenants each get their own.
Rekey House in Concord
Rekey House service in Concord is a full exterior lock rekey: front door, back door, garage entry, side door, any lock that opens the house from outside. Most jobs run $170 – $340 for a typical 3 – 4 lock home, and we often key everything to a single key so you stop carrying a ring of four different cut profiles.
One Key for Every Door
If you bought a house off Clayton Road and the previous owner handed you three keys that all look the same but only two work, we fix that. We rekey every exterior cylinder to the same key, matching Schlage or Kwikset keyways so the whole house is on one key ring. This is standard practice for us, not an upcharge.
Key Control After a Life Change
Divorce, new roommate, in-law moved out, contractor finished the remodel. Any time the number of people who had a key becomes unclear, a house rekey in Concord resets access. We give you a written key control plan showing exactly how many keys exist and how many cylinders we rekeyed.
Trusted Brands We Service in Concord
We’re trained and equipped to rekey Schlage, Kwikset, Medeco, and Yale hardware, from the builder-grade deadbolts on 1960s Concord ranches to high-security Medeco cylinders on commercial storefronts near Willow Pass Road. We carry pin kits for these keyways on the truck, so a Schlage or Kwikset rekey in Concord doesn’t turn into a two-visit job waiting on parts. If your deadbolt is worn past clean-and-rekey territory, we’ll show you the cylinder, explain what’s failing, and give you a written price for a replacement before any work starts.
Common Rekey Locks Problems We See in Concord Homes
- Stiff cylinders on older ranch homes: Homes off Concord Blvd and around Todos Santos often have original builder-grade Kwikset or Schlage locks. Years of Contra Costa heat bakes the factory lube, pins hang up, and the key fights you. A rekey here also needs a clean and re-lube, not just a pin swap.
- Bootleg “rekey starting at” quotes: Concord gets heavy traffic on I-680 and the BART corridor, and lots of dispatch services prey on that. They quote a low teaser number, then stack trip fees, after-hours fees, and “cylinder upgrade” charges on your doorstep. Our price is written before we dispatch, and it’s the invoice price.
- Rekeying only the front door: A new tenant can still open the side door or garage with the old key because only the front lock got rekeyed. We rekey every exterior lock tied to the same key control plan so nothing slips through.
- Unverified technician at the door: You should be able to match the person at your door to the company you called. Our technician arrives in uniform, with a truck matching our company name, and you see a live trackable arrival time plus a photo of the tech before they knock.
