Fast, Reliable Rekey Locks Across Pacheco
Rekeying a lock in Pacheco typically costs $25 to $45 per cylinder, and a full house with three or four locks usually lands between $95 and $160. That price is set in writing before our tech leaves the driveway, and it does not change at your door. If you just bought a home off Pacheco Blvd, fired a contractor who still has a key, or split with a roommate near the 680 interchange, we can have a uniformed tech at your Pacheco door in about 45 minutes to an hour. Call (409) 405-4485 and you will talk to a live person, not a menu tree.
Pacheco’s housing stock is a mix of 1960s ranchers and newer infill, which means the same property often has two different lock brands on two different doors. We plan for that before we show up. You get one new key for every door, no hardware swap if the cylinders are in decent shape, and old keys are dead before we leave.
Why Preston Locksmith & Security Is Pacheco’s Preferred Rekey Locks Company
We have worked enough Pacheco homes to know what a rekey here actually involves, and it is rarely just one lock. Older ranchers off Center Avenue still run original contractor-grade Kwikset cylinders whose pins are so worn that a straight rekey will not hold. Newer builds near the Boulevard and 680 side often mix Schlage deadbolts on the front with a different keyway on the slider or garage entry. A low-bid quote that only rekeys the front door leaves you carrying two keys and wondering why you paid for the job at all.
Kevin Yoon leads our team, and every tech who rolls to a Pacheco job is background-checked, uniformed, and held to the Relay Standard. You get a live trackable arrival time before we dispatch, so you are not stuck in a four-hour window. You get a written price before any work starts. You get before-and-after photos of the cylinders we touched. And you get the 365-Day Done Right Promise on every rekey: if it is not done right, we make it right, including a free second visit if the repair fails.
Pacheco residents call us because the quote is not a teaser. The number we give on the phone is the number on your invoice. No arrival fee added at the door, no “we found an unexpected problem” upcharge after the fact. If a cylinder is too worn to rekey, we tell you the replacement cost in writing before we touch it, and you approve it first.
Rekey Service in Pacheco
Rekey Locks in Pacheco means swapping the internal pins and springs inside an existing cylinder so the old key stops working and a new key takes over. The lock stays on the door. Nothing about the hardware changes except the key. For a Pacheco homeowner who just closed escrow on a rancher off Pacheco Blvd or a condo near the interchange, a rekey is the fastest way to guarantee that no previous owner, tenant, contractor, or real estate agent still has a working key to your front door.
Most Pacheco rekeys run $25 to $45 per cylinder. A standard front door plus side gate plus garage entry is usually three cylinders, so figure $75 to $135 for the whole job. If your cylinder is a high-security Medeco or Yale, expect the top of that range or slightly above, because the pin kits cost more and the work takes longer to do right.
New Home Rekey
Closing escrow in Pacheco means previous owners, their kids, the agent, the handyman, the cleaning crew, and possibly a neighbor all held keys at some point. You will never know how many copies are out there. We rekey every entry the same afternoon, hand you one new set of keys, and confirm each cylinder turns smoothly before we mark the job done.
Lost Key Rekey
If a key is missing and you are not sure whether it was lost or taken, rekeying is cheaper than replacing every lock and just as secure. We can also rekey a single cylinder if only one key is unaccounted for, while leaving the rest of your Pacheco home on the same existing key.
Keyed Alike in Pacheco
Rekey Locks in Pacheco often includes a request to have every lock on the property keyed alike, meaning one key operates the front deadbolt, the back slider, the side gate, and the garage entry. It is the most useful upgrade we perform on Pacheco lots where people actually come and go through two or three different doors. One key in your pocket, no fumbling through a ring of six.
Keyed alike pricing follows the same per-cylinder rate, $25 to $45, but the real value is in getting every keyway matched in one visit. Older Pacheco ranchers frequently have a Kwikset keyway up front and a Schlage keyway out back. Those are different pin systems. A tech who only rekeys the front and hands you two keys did not finish the job. We rekey both to the same new key, same bitting, same blank.
Front and Back Doors on One Key
We rekey the front deadbolt and the back entry, including sliders with bolt locks, to a single key. If you have a newer smart lock or keypad on one door, we can usually key the cylinder behind it to match your mechanical locks, so the physical override also works with your main key.
Side Gate and Garage Included
On Pacheco properties where the side gate is the everyday entry, skipping it on a rekey is a security hole. We include every gate, garage walkthrough, and storage door in the quote up front, so you are not surprised later by a door we ignored. The written price covers the whole property, not just the front.
Trusted Brands We Service in Pacheco
We carry pin kits and blanks for Kwikset, Schlage, Medeco, and Yale on the truck, which means we can rekey most Pacheco homes on the first visit without running to a supply house. Older Baldwin hardware shows up on higher-end Pacheco remodels, and we service that too. If a cylinder is too worn for a reliable rekey, like the contractor-grade Kwikset units common on 1960s ranchers, we tell you honestly and quote a replacement before any work happens. The price does not change between that conversation and the invoice.
Common Rekey Locks Problems We See in Pacheco Homes
- Worn contractor-grade Kwikset cylinders on older ranchers. Pins and springs wear down over decades. A straight rekey will sometimes not hold, and the cylinder needs replacing before new keys will track reliably. We check for this before we rekey, not after you call us back.
- Mixed keyways on one property. Original Kwikset up front, newer Schlage out back, sometimes a Medeco on the side gate. A low-bid quote that ignores the second keyway leaves you with two keys and no savings. We match everything to one key in the same visit.
- Front-door-only rekeys. On Pacheco lots where the side gate and garage entry are the real everyday doors, only rekeying the front is a half-done job. We include every door you actually use in the written quote.
- Rekeying after a tenant or contractor change. If a tenant moved out or a remodeling crew finished up, every key they held is still a working key until the cylinder is rekeyed. We rekey the same day, and old keys are dead immediately.
Pricing for Rekey Locks in Pacheco, CA
A single cylinder rekey in Pacheco runs $25 to $45. Two cylinders, like a front deadbolt and a side gate, run $50 to $90.

Keying additional cylinders to match runs the same per-cylinder rate, and we quote the total before we dispatch.
