Why Preston Locksmith & Security Is Fremont’s Preferred Rekey Locks Company
Fremont homeowners call us because we show up when we say we’ll show up, and the price we quote on the phone is the price on the invoice. No dispatch fee added at the door, no upsell to parts you don’t need. The technicians we send are background-checked, uniformed, and you can see their live location before they knock. Kevin Yoon, who leads our team, built this operation around a simple promise: write the price down, show the work when it’s done, and stand behind it for 365 days.
We know Fremont’s housing stock well enough to recognize the difference between a 1960s Schlage cylinder in Centerville and a builder-grade Kwikset in a Mission San Jose townhouse before we even touch the door. That matters, because the rekey job isn’t one-size-fits-all here. Our Rekey Locks team carries pin kits for vintage mortise cylinders and modern deadbolts alike, so there’s no “we’ll have to come back” delay.
Every job includes the 365-Day Done Right Promise. If the rekey isn’t done right, we return and make it right at no charge, no argument, no second invoice.
Rekey House in Fremont
Rekey house work in Fremont means changing the internal pins in every door lock so your old keys stop working and one new key operates everything. Homeowners typically need a whole-house rekey after buying, after a tenant moves out, or when a set of keys goes missing. On a standard Fremont single-family home with three to four entry doors, a full rekey runs $145 – $285 total, written down before we begin.
What the job involves
We remove each lock cylinder, swap the internal pins to match a new key pattern, then reinstall and test the lock. For older Fremont doors with original mortise locks, we pull the cylinder out of the mortise body and re-pin it in place rather than replacing the whole unit unless the body itself is failing. The hardware stays, the keys change.
Matching every door to one key
Most Fremont homes have a mix of deadbolts, knob locks, and sometimes a side gate or back slider. During a whole-house rekey, we cut every cylinder to the same key without swapping any visible hardware, so you’ll turn the deadbolt on the front door and the lock on the gate with one key.
Lock Rekey in Fremont
Lock rekey in Fremont is the same core service, scoped to a single door or a handful of specific locks instead of the whole house. A single deadbolt rekey runs $95 – $130, and adding a matching knob or lever cylinder is usually $40 – $70 more per lock. This is the job Fremont renters and landlords request before a tenant turnover, and it’s also the fix when you want one door keyed differently from the rest of the house.
When a full replacement makes more sense
If a cylinder has already been drilled, re-pinned incorrectly by someone else, or is a no-name import with non-standard pins, the rekey turns into a replacement. We’ll tell you that before we start, show you the worn cylinder, and give you a written price for the swap before any work begins. No surprises after the fact.
Rekey vs. replacing the hardware
Rekeying keeps your existing lock bodies and changes only the pins inside, which costs less and keeps matching finishes across the house. Replacing the hardware means new visible parts on every door. For most Fremont homes, rekeying is the right call unless the lock itself is worn or damaged.
Trusted Brands We Service in Fremont
We rekey and service Kwikset, Medeco, Yale, and Baldwin hardware every week in Fremont, and we stock common pin kits and cylinders locally so jobs don’t stall waiting on parts. Older Irvington and Centerville homes often have original Kwikset or Yale cylinders we’ve re-pinned hundreds of times, while newer Mission San Jose and Warm Springs builds lean Baldwin and Medeco for entry sets and side gates. If you’re not sure what brand is on your door, we’ll identify it when we arrive and confirm the rekey price before starting.
Common Rekey Locks Problems We See in Fremont Homes
- Vintage cylinders that no longer match the key pitch. Older Schlage and Kwikset cylinders in 1950s and 60s Fremont homes often have worn pins that make a new key stick or refuse to turn. Re-pinning with a fresh pin kit resolves it without swapping the hardware.
- Mortise locks that scare off inexperienced techs. Irvington and Centerville homes built before 1970 frequently have original mortise bodies. A tech who only knows modern bored locks will quote a full replacement because they can’t re-pin the mortise cylinder in place. We do it on site.
- Tenant turnovers with keys floating around. Fremont rental turnovers in the Warm Springs and Ardenwood areas are a constant stream of rekey requests. Multiple previous tenants, roommate situations, and handyman copies mean no one truly knows how many keys are out there, which is why a rekey rather than a duplicate is the safe call.
- Builders who keyed every home alike. In many Fremont tract developments, the original builder hardware was keyed identically or with only a few key patterns. A rekey to a unique key pattern is the only way to guarantee your key doesn’t open a neighbor’s door or vice versa.

FAQs About Rekey Locks in Fremont
Every technician we send is background-checked, in a Preston Locksmith & Security uniform, and arrives with a live trackable arrival time you can watch from your phone. Before they touch your door, they’ll show you the written work order with the price you were quoted. If you want more proof, call (409) 405-4485 while they’re standing there and our dispatcher will confirm the technician’s name and photo.
In most cases we can rekey the original mortise lock in place, and that’s true for the majority of 1950s and 60s Fremont homes we see. We pull the cylinder from the mortise body, re-pin it to your new key, and leave the original hardware intact. We only recommend replacement if the mortise body itself is cracked, the bolt is binding, or the cylinder has already been drilled. Call (409) 405-4485 with a photo of the lock and we’ll tell you what you’re likely working with.
A rekey changes the internal pins so old keys stop working, but keeps all the visible hardware in place. New locks mean replacing the entire lock body on every door. Rekeying is faster, cheaper, and leaves the door looking the same, which is why most Fremont landlords choose it for turnovers between tenants. A typical single-family turnover with three entry doors runs $145 – $285, written before we start.
Yes, and most whole-house rekeys in Fremont are exactly that: one key for the front door, back door, side gate, and any other locks you want matched. We cut every cylinder to the same key pattern during the job, test each lock, and hand you the new keys before we leave. If you’d rather have a master key system where one key opens everything but individual keys open only certain doors, we can set that up too. Call (409) 405-4485 and we’ll price it out.
A standard three-door Fremont home takes under two hours from arrival to finished job, including testing every lock and handing over the new keys. Older mortise locks add a little time, but we recently rekeyed a 1962 Irvington ranch with an original mortise front lock, a deadbolt, and two matching entry knobs in under 90 minutes. The quoted price didn’t move. For an exact time estimate, call (409) 405-4485 and describe the doors: front door, back door, gate, slider, and any others.
