You don’t pay for new deadbolts. For most National City homes, a rekey runs $85 to $160 for labor, plus $15 to $25 per cylinder, with a written price confirmed before we dispatch. If you’re off Highland Avenue or anywhere between the 5 and the 805, call (409) 405-4485 and a live person answers.
We know National City’s housing stock. It’s not one housing type. It’s pre-war stucco bungalows west of I-5, mid-century ranch houses near Kimball Park, and infill townhomes along the 54 and Mile of Cars corridor. Each takes a different rekey approach, and each deserves a price in writing before a truck rolls. That’s how Preston Locksmith & Security works, and it’s why homeowners here call us when a key changes hands.
Why Preston Locksmith & Security Is National City’s Preferred Rekey Locks Company
Since 2008, Preston Locksmith & Security has built its National City reputation one door at a time. Our customers aren’t just a number in a dispatch queue. When you call, you get a live person. When we quote, the price is in writing. When our tech arrives, you get a live, trackable arrival time so you’re not standing by the front window for four hours wondering if anyone is coming.
Every technician we send to National City is background-checked and arrives in uniform. That matters when you’re handing over the keys to every lock on your house. You’ll see a name, a face, and a Preston-branded vehicle before the doorbell rings. Our work is backed by the 365-Day Done Right Promise. If a rekey isn’t done right, we make it right, with a written guarantee stamped on every job, no exceptions. Kevin Yoon leads our team, and he holds every tech to the same standard across the National City service area.
Rekey House in National City
Rekey house in National City means pulling every exterior lock cylinder, repinning it to a new key, and making sure one key works every door that leads outside. Not just the front door. The back door, the side door off the carport, the garage entry, the slider if it has a keyed handle. If a door has a key, it gets rekeyed. That’s the only way a rekey actually secures your home, whether it’s a 1940s bungalow off East 8th Street or a newer townhome near Plaza Boulevard. A full house rekey in National City typically runs $140 to $240, depending on lock count and cylinder type.
What the Job Involves
We pull each cylinder, remove the old pins, and install new pins matched to a fresh key. Old keys go dead immediately. The lock body stays in the door. For modern Schlage and Kwikset deadbolts, it’s quick. For older mortise lock bodies common on National City’s west side, it takes more care but is almost always rekeyable.
When a National City Homeowner Needs It
You closed on a house and you don’t know who still has a key. You had a tenant move out off Paradise Valley Road. A key went missing from a bag. A cleaner, contractor, or dog walker no longer works for you. Each is a reason to rekey, and each is a job we can usually complete the same day you call.
Lock Rekey in National City
Lock rekey in National City is the same service, whether you need one deadbolt done or six. We repin the cylinder so old keys stop turning, and we cut you new keys on the spot. A single lock rekey in National City runs $85 to $130, including the service visit and one new key. Additional locks drop the per-lock cost. If you have a mixed set of Kwikset and Schlage locks, we can often convert them to a single key control set so one key operates everything, even if the brands don’t match.
One Lock vs. Whole House
Rekeying one front deadbolt does not secure the rest of the house. We see it all the time in National City: someone buys a house near Sweetwater Road, rekeys the front door, and never thinks about the garage entry. Then a neighbor’s key, a contractor’s key, or a previous tenant’s key still opens the back. We’ll check every lock and give you a single price to do them all.
Mortise Locks and Non-Destructive Entry
West-side National City bungalows often have original mortise lock bodies. Some locksmiths reach for the drill. We don’t, unless the lock is genuinely failed. A rekey almost always gets a working mortise lock back in service for far less than replacement. We’ll tell you honestly which route makes sense.
Trusted Brands We Service in National City
Our techs are trained on Schlage, Kwikset, and Medeco hardware, plus commercial-grade systems from Abloy. Most National City homes we see run standard Schlage or Kwikset deadbolts, but we regularly rekey Medeco high-security cylinders for small business owners and landlords near the Mile of Cars. We stock common pins, springs, and key blanks for these brands on the truck, which means a rekey doesn’t turn into a two-day wait for parts.
Common Rekey Locks Problems We See in National City Homes
- Old mortise locks getting replaced unnecessarily. A 1940s bungalow off East 8th Street will often have a tired mortise lock body. Many locksmiths quote a full replacement. We rekey and service these locks, keeping the original door hardware intact and saving the homeowner hundreds.
- Rekeying only the front door. The back slider and garage entry still work on the old key. The house isn’t secured. We rekey every keyed entry, not just the one facing the street.
- Phone quotes before the tech sees the lock. A lock is not a lock. A mortise lock body and a modern ANSI Grade 1 deadbolt are different jobs with different labor. We confirm your lock type before we lock in a price.
- Drilling when non-destructive entry works. A drill is faster for the tech, but it destroys your hardware. We use non-destructive entry tools whenever the lock is functional, then rekey it. No drilling, no upsell, no surprise replacement invoice.

FAQs About Rekey Locks in National City
Yes. We ask about your lock type, confirm whether you have mortise locks or modern deadbolts, and give you a written price before a technician is dispatched. The price we quote is the price on your invoice. There is no add-on surprise when the tech arrives. Call (409) 405-4485 and we’ll walk you through it.
Almost always, it can be rekeyed. Mortise lock bodies on National City’s pre-war homes are built to be serviced, not thrown away. We pull the cylinder, repin it, and have it working on a new key without damaging the door. Replacement is only the answer if the lock body itself is cracked or seized beyond repair, which we’ll show you with photos before any work begins.
A typical four-door house rekey takes 45 minutes to an hour once we’re on site. Older mortise locks take a little longer. A single deadbolt is often done in 20 minutes. We’ll give you a live arrival time when you book, so you know exactly when we’ll have your new keys ready.
You’ll receive a live, trackable arrival link before we get there. Our tech arrives in a Preston-branded vehicle, wearing a uniform, with a name badge. You’ll also get before-and-after photos of the work. If anything looks off when the doorbell rings, call us and we’ll confirm the tech’s name on the spot.
Yes. This is one of the most common requests we get in National City. We can repin most mixed-brand setups to a single key control set, so one key operates the Kwikset deadbolt on the front door and the Schlage on the back. We’ll confirm your specific hardware before we quote, and the price is written before we start.
