Fast, Reliable Rekey Locks Across Alamo
Rekeying a lock in Alamo typically runs $25 – $45 per cylinder, takes 20 – 30 minutes per lock once we’re on site, and the price you confirm on the phone is the price on the invoice. We serve every corner of Alamo, from the Alamo Oaks loop off Danville Boulevard to the larger hillside properties along Stone Valley Road, usually arriving within 45 – 60 minutes of your call. Preston Locksmith & Security is an Alamo Residential Locksmith crew that gives you a live arrival time you can track, before-and-after photos of every cylinder we touch, and a written price before a single tool leaves the bag. Call (409) 405-4485 any hour and you’ll reach a live person, not a voicemail tree.
Why Preston Locksmith & Security Is Alamo’s Preferred Rekey Locks Company
Alamo Commercial Locksmith and residential customers call us for two reasons: the quote is locked in writing before we dispatch, and the technician who shows up is the person we said would show up. That’s The Relay Visibility Guarantee – a written price, a trackable arrival time, and photo documentation of the work. It sounds basic until you’ve dealt with a random dispatch service that sends an anonymous van and a vague hourly rate.
Kevin Yoon runs our bay area operations and holds every job to The Relay Standard: if it’s not done right, the 365-Day Done Right Promise means we come back and make it right, free. That promise is written on every rekey we perform in Alamo. We answer the phone 24/7. We wear uniforms. We carry Schlage, Kwikset, and Medeco pins and cylinders in the van, not just a drill and a blank key.
When an Alamo resident calls about a rekey, we already know what to expect: original 1960s and 70s builder-grade locksets on ranch homes, pin-and-tumbler cylinders that are often still perfectly serviceable, and a homeowner who wants key control without replacing every piece of hardware. That context is the difference between a 90-minute visit and a four-hour upsell.
Lock Rekey in Alamo
Lock Rekey in Alamo means pulling the cylinder out of the existing hardware, swapping the internal pins to a new key, and reinstalling everything so the old keys stop working immediately. It’s the fastest way to gain key control after a home purchase, a tenant departure, or a lost key. On a typical Alamo ranch built in the late 60s or early 70s, the original Kwikset or Schlage key-in-knob sets are usually good candidates for a rekey – the pins are worn but the cylinder body is still solid.
Cost for a standard Alamo lock rekey runs $25 – $45 per cylinder. A five-door home with matching keyways usually lands around $125 – $225 total, written and confirmed on the phone before we dispatch. That number includes cleaning and lubrication of each cylinder, cutting new keys, and testing every door twice before we hand them over.
Key Control After a Purchase or Tenant Change
When you close on a home in Alamo, you have no way of knowing how many copies of the old key are floating around. A rekey changes the pin configuration inside the cylinder; the hardware stays, the key changes. You get new keys, the old ones stop working, and you don’t pay for six new locksets you don’t need.
Worn Cylinder Reality Check
Occasionally an old cylinder is too worn to rekey cleanly – the new pins won’t seat and the key will stick or fail to turn. We check each cylinder before we re-pin it. If one needs replacing, we show you the wear and the replacement cost is agreed before any new part goes in. You’re never surprised by a growing bill.
Locksmith Rekey in Alamo
Locksmith Rekey in Alamo is the same mechanical procedure whether you call it a rekey or a re-pin: we re-key the cylinder to match a new key, eliminating access for anyone holding the old one. But the locksmith part matters because our techs are trained on the full mechanical range – Medeco high-security cylinders, Schlage deadbolts, Kwikset knobs, and every builder-grade pin-and-tumbler you’ll find in an Alamo ranch.
Most Alamo jobs take 20 – 30 minutes per cylinder, excluding drive time. A three-door house runs about an hour on site. A five-door with two double-cylinder deadbolts runs closer to two hours. The written quote you get on the phone is the invoice total unless you decide to add work after seeing the condition of an existing cylinder. No call-out surcharge, no “arrival fee” piled on at the door, no upsell to new hardware we can’t show you is necessary.
When Rekeying Beats Replacing
New hardware makes sense when the existing lock is truly failing. But most of what gets replaced during “rekeys” in Alamo is salvageable. We’d rather re-pin a solid Schlage deadbolt to a fresh five-pin schedule than swap it for a cheap box-store knob. The keys match, the deadbolt throws cleanly, the price stays a fraction of hardware replacement.
Deadbolt and Backset Verification
A proper rekey includes verifying each deadbolt is ANSI Grade 1 or Grade 2, that the backset is measured (2-3/8″ vs 2-3/4″ is common in older Alamo doors), and that every door uses the same keyway. Otherwise you end up with mismatched keys across the house. If a deadbolt fails a function test, we tell you before any pin is touched.
Trusted Brands We Service in Alamo
Our crews carry a full pinning kit for Schlage, Kwikset, and Medeco hardware, with additional cylinders and parts for Yale and Baldwin jobs kept stocked on the van most days. Alamo’s housing stock is heavy on Kwikset and Schlage from the original build era, so we keep plenty of five-pin and six-pin kits ready and can rekey those cylinders without waiting on parts. If you have a Medeco or Abloy high-security cylinder, the rekey requires the specific pins and key blanks for that system – we schedule those with a written scope and flat per-cylinder price before any work begins. Call (409) 405-4485 and tell us the brand stamped on your key or faceplate; we’ll confirm coverage and pricing in one call.
Common Rekey Locks Problems We See in Alamo Homes
- The bait-and-switch rekey quote. A locksmith advertises a cheap rekey price on the phone, then arrives at your Alamo home and claims every cylinder needs full replacement at triple the number. Our written quote covers the rekey unless a cylinder is genuinely unserviceable, and if that happens you’ll see the wear yourself before approving anything.
- Worn builder-grade Kwikset cylinders. In original 1960s – 70s Alamo ranches, we see cylinders that have been operating for 50 years. Sometimes the new pins won’t seat properly on a rekey – the key sticks, turns hard, or won’t turn at all. We check before re-pinning so you don’t discover this after we’ve left.
- Mismatched keyways across doors. Over decades, prior owners often replaced one lock at a time, mixing Kwikset, Schlage, and generic brands. A single rekey key will not work across mixed keyways. We map every cylinder before we re-pin and tell you if one key will control the whole house or if some doors need a hardware decision.
- Cross-threaded or stripped cylinders from past DIY attempts. Alamo homeowners who try a rekey themselves or hire a handyman often cross-thread the cylinder when reinstalling it. We see this enough that we inspect every cylinder’s threading before re-pinning. A fresh cylinder is sometimes the only honest fix, and we quote it separately before touching the lock.
Pricing for Rekey Locks in Alamo, CA
A standard Rekey Locks job in Alamo runs $25 – $45 per cylinder for pin-and-tumbler hardware like Kwikset and Schlage. High-security cylinders from Medeco or Abloy run $45 – $75 per cylinder because the key blanks and pins cost more and the work requires a specific pinning kit. Most Alamo homes have 3 – 5 entry points, so a full-house rekey generally lands between $100 and $250. Deadbolt verification, key cutting, and cylinder cleaning are included. You’ll always get a written price on the phone before we dispatch, and that number is the invoice unless you approve an additional line item after we show you the condition of your hardware. Call (409) 405-4485 for a free estimate.

FAQs About Rekey Locks in Alamo
Yes, every rekey quote is written and confirmed on the phone before anyone drives to your Alamo home. A standard cylinder rekey runs $25 – $45, and we confirm the number of locks and keyways in that one call. That price is what you pay unless you approve an additional line item after we show you why it’s needed, which the 365-Day Done Right Promise and written guarantee back up. Call (409) 405-4485 for an exact quote – estimates are free.
In most cases, yes – the original Kwikset or Schlage cylinders on those Alamo ranch homes can be re-pinned to a new key without replacing the lock bodies. We check for worn cylinder threading and stripped pins before we re-pin, so you’re not paying for a rekey that won’t hold. If a specific cylinder is too far gone, we show you the condition and quote a replacement cylinder separately before any work proceeds.
Plan on 20 – 30 minutes per cylinder, so a three-door Alamo home runs about an hour on site; a five-door home with double-cylinder deadbolts runs closer to two hours. That includes pulling the cylinders, re-pinning, cleaning, cutting new keys, and testing every deadbolt twice. Our arrival window is live-trackable so you aren’t waiting in a four-hour block.
The technician who arrives at your Alamo door is background-checked, uniformed, and will match the name and arrival time you already received on your phone. Before work starts you get a written price, and during the job you get before-and-after photos of each cylinder. That’s The Relay Visibility Guarantee, and it’s the same standard on every job including a free second visit if the repair fails. Call (409) 405-4485 and a live person answers 24/7.
Yes – rekeying changes the pin configuration inside each cylinder, so every key cut to the old schedule stops working immediately. You get new keys, and anyone holding an old copy is locked out without you replacing the hardware. For a home with multiple exterior doors in Alamo, we verify every cylinder uses the same keyway before re-pinning so one new key controls the whole house.
