Fast, Reliable Rekey Locks Across Hayward
Rekeying a lock in Hayward means swapping the internal pins and springs so old keys stop working, and it typically costs $95 – $160 for a standard deadbolt or knob when we come to you. You don’t need new hardware, you don’t need new keys to match other doors, and you don’t need to wait through a four-hour window. Call (409) 405-4485 and you’ll get a written price before anyone is dispatched, a live arrival time you can track, and a background-checked technician in uniform who shows up with the right pin kit for your specific lock.
Hayward is not a one-size-fits-all rekey market. A 1920s bungalow off B Street with an original mortise lock is a completely different job from a 1970s townhouse off Mission Boulevard with standard Kwikset deadbolts. We carry the cylinders, pins, and tools for both. That’s the kind of local knowledge that keeps a rekey from turning into a surprise hardware replacement you didn’t ask for.
Why Preston Locksmith & Security Is Hayward’s Preferred Rekey Locks Company
Hayward homeowners and small-business owners call us because we name the price before we dispatch. That’s the whole deal. We write down the exact cost, you see it, you approve it, and that same number lands on the invoice when the work is done. No arrival surcharge, no “Oh, this lock is special so it costs more.” If a tech quoted you a teaser price on the phone and changed it on your doorstep before, that’s exactly the experience we built Preston Locksmith & Security to replace.
Our technicians know the lock hardware that actually exists in Hayward. Downtown bungalows and Victorians near the Hayward Hills carry original mortise locks with non-standard cylinder sizes. Mission-Foothill neighborhoods and South Hayward subdivisions skew toward Schlage, Kwikset, and Yale tubular deadbolts. We stock pin kits and replacement cylinders for Medeco, Baldwin, and Yale alongside everyday hardware, so we rarely leave a job waiting on a part. When you book with us, you get a live trackable arrival time and before-and-after photos of every cylinder we rekey. That’s the Relay Visibility Guarantee, and it’s standard on every job, no exceptions.
Rekey House in Hayward
Rekey House is the job where every exterior lock in your home gets repinned to work on one new key, and it starts at about $160 for a standard Hayward ranch or townhouse with three or four common deadbolts and knobs. This is the service you need after buying a home, after losing a key, after a tenant moves out, or after a roommate situation changes. In Hayward, where plenty of homes have had multiple owners and each one had a spare key floating around, a full-house rekey is the fastest way to know for sure who can and can’t open your front door.
Single-Key Access for Every Door
If your home has separate keys for the front door, the back door, and the garage entry, we can rekey all of them to one key. That includes mixed hardware. A Kwikset deadbolt on the front, a Baldwin knob on the side door, and an older Schlage thumbturn on the back is normal for a Hayward house that’s been added onto over the years. We pin each cylinder independently so they share one key profile.
Non-Destructive, Same-Day Work
Nothing gets drilled. Nothing gets replaced unless it’s genuinely worn past the point where a rekey makes sense. We remove the cylinder, replace the pins and springs, and reinstall it in the same housing. Most three-door houses are done in under an hour, and you keep the original hardware. If you’re in the Hayward Hills and the fog has rusted a cylinder, we’ll tell you before we touch it and give you a written price for the replacement cylinder before we proceed.
Lock Rekey in Hayward
Lock Rekey is a per-cylinder job where one specific lock gets repinned to a new key, and it runs $95 – $160 in Hayward depending on the cylinder type. You might need a per-lock rekey if one door in the house has a different key than the others and you want it matched. Or if you just bought a new place in the Burbank neighborhood and the seller’s key is still out there somewhere. Or if a specific lock stopped turning smoothly and you’d rather start fresh than keep using a key that’s worn down to a nub.
Mortise Cylinder Rekey for Older Homes
Hayward’s housing stock splits sharply across the fault line. Pre-war bungalows near downtown and the Hayward Hills often carry original mortise locks and thin-gauge builder hardware, so a rekey there is a pinning and key-control job, not a drop-in swap. A neighboring city like Union City or San Leandro tends toward 1960s – 80s tract homes with standard tubular deadbolts, which is a different job altogether. If you’re in an older Hayward home, we match your mortise cylinder to the new key rather than telling you the only option is to replace the whole lock.
Bump-Resistant and Grade 1 Hardware
If you’re rekeying anyway and want to harden the door at the same time, we can swap a worn cylinder for an ANSI Grade 1 deadbolt while we’re in there. That’s a common call for homeowners near the Hayward Shoreline, where wind-driven rain and salt air age outdoor locks faster than inland hardware. The price for adding a Grade 1 deadbolt is separate from the rekey and always quoted in writing before we start.
Trusted Brands We Service in Hayward
Our techs service Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware. That’s not marketing vocabulary. It means we show up with the actual branded pin kits and cylinder followers for your actual lock, not a universal kit that kind of fits. Rekey Locks work on premium deadbolts from Medeco and Baldwin needs different pins than a standard Schlage. We stock for both in our Hayward service vehicles, so turnaround is same-day for most residential and light commercial jobs. If your Yale smart lock accepts a keyed backup cylinder, we can rekey that too. If it’s keyless-only, that’s a programming call, not a pinning job, and we’ll tell you that honestly before you spend a dollar.
Common Rekey Locks Problems We See in Hayward Homes
- Original mortise locks with non-standard cylinders. Downtown Hayward bungalows and Victorians often have cylinders that don’t match modern Schlage or Kwikset pin kits. A tech who only carries those kits ends up ordering a part online and leaving the job half-done. We carry the right cylinders for the job from the start.
- Hillside homes with mismatched rekeys from previous owners. If a Hayward Hills home has four exterior doors that were rekeyed separately over the years, you might have three different keys for one house. We rekey all cylinders to a single key without replacing the hardware, and if you want a proper master key system for a rental or multi-family property, we can set that up too.
- Teaser phone quotes that change on arrival. We hear this from Hayward customers weekly: a dispatcher quotes a low number, the tech arrives and says the job needs a hardware upgrade, and the price triples. That’s why our price is written and confirmed before dispatch. The number we agree on is the number on the invoice.
- Fog and marine air damage near the Hayward Shoreline. Salt-heavy air wears cylinders and corrodes pins faster than you’d expect. A rekey on a shoreline home sometimes requires a new cylinder when the original is too pitted to accept new pins. We’ll show you the cylinder and give you the price for the replacement before we touch it.
Pricing for Rekey Locks in Hayward, CA
A standard rekey of one deadbolt or knob in Hayward runs $95 – $160, and a full-house rekey typically runs $160 – $280 when we’re rekeying three to five cylinders. Mortise cylinder rekeys in older homes run toward the higher end because the cylinders take more time to pull and pin. Adding a new Grade 1 deadbolt starts around $180 including installation, and we’ll show you the exact hardware options and prices before anything goes on the door. Call (409) 405-4485 for an exact written estimate. The estimate is free, the price on the phone is the price on the invoice, and there is no call-out surcharge added when the tech pulls up in front of your Hayward address.

FAQs About Rekey Locks in Hayward
No. In most cases we pull the mortise cylinder, replace the internal pins and springs, and reinstall the same lock body. If the cylinder itself is corroded or cracked beyond a clean rekey, we’ll show it to you and quote a replacement cylinder in writing before we proceed. We never drill a mortise lock in a Hayward bungalow unless it’s fully seized, and even then we’ll explain every step before it happens. Call (409) 405-4485 and describe your lock; we’ll tell you what to expect.
A single deadbolt takes 20 to 35 minutes on-site. A three-door house takes 45 to 75 minutes. Mortise cylinders on older downtown Hayward homes add about 10 minutes per cylinder because of the extra steps to remove and reinstall the lock body. Your live arrival window is texted to you before the tech leaves, and you can track the van on the way to your home.
Yes. We rekey each cylinder, even mixed-brand hardware from Kwikset and Baldwin or Schlage and Yale, to the same key profile. This is one of the most common requests we get from homeowners in the Hayward Hills who have four exterior doors and three different keys. We can also set up a master key system so you have one master key and separate keys for tenants, a cleaner, or a home office. Call (409) 405-4485 and we’ll price the whole house, not just one door.
You get a live trackable arrival link before the tech leaves, a photo of the technician in uniform before they knock, and the written price you approved when you booked. The tech arrives in a Preston Locksmith & Security vehicle and carries a badge matching the name you were sent. If anyone ever knocks and doesn’t match the photo we texted, don’t open the door. That’s not us. That’s the kind of clarity we built into the Relay Visibility Guarantee because Hayward residents told us they wanted it.
If your smart lock has a keyed backup cylinder, yes, we can rekey it so the physical key changes while the keypad codes stay programmed. If your lock is keyless-only and has no physical cylinder at all, rekeying isn’t the service you need; we’ll tell you that before we schedule anything and point you to the right fix. Many Hayward homeowners with Yale or Kwikset smart deadbolts ask this exact question. The answer is: it depends on whether a key can turn in the lock. Call (409) 405-4485 with the brand and model if you want us to check.
