You don’t know who has copies of the old keys.

Why Preston Locksmith & Security Is La Cañada Flintridge’s Preferred Rekey Locks Company
The locksmith trade has a well-earned reputation problem: vague hourly rates, anonymous techs, and a bill that swells between estimate and invoice. We built Rekey Locks service at Preston Locksmith & Security to kill that playbook. Every job starts with a written price. You get a live trackable arrival time, and the tech who shows up is background-checked and in uniform. Before they knock, you know who is coming, what they look like, and when they’ll arrive.
We handle the specific reality of La Cañada Flintridge housing stock: original 1950s and 1960s mortise locks, builder-grade Kwikset knobs, and newer smart deadbolts all on the same property. That mixed-age hardware is the norm here, not the exception. Our techs carry pins, springs, and cylinders for Schlage, Kwikset, Yale, Baldwin, Medeco, and Mul-T-Lock, so a rekey job does not stall waiting on a part. The 365-Day Done Right Promise applies to every rekey in La Cañada Flintridge. If it is not done right, we make it right, no charge and no argument.
Rekey Door Lock in La Cañada Flintridge
Rekey Door Lock work in La Cañada Flintridge means resetting the internal pins inside an existing lock cylinder so the old keys stop working and a new key operates the same hardware. No new hardware needed, no drilling, no mess. We do this constantly for homeowners on Descanso Drive, Chevy Chase Drive, and up in the Flintridge hills after a move-in, a tenant turnover, a divorce, or a lost key. A standard rekey runs $25 to $45 per cylinder, written price confirmed before we start.
What the Tech Actually Does
We disassemble the cylinder, remove the old pins, insert new pins matched to your new key, and reassemble. On a Schlage or Kwikset cylinder, this takes about ten minutes per lock. On older mortise cylinders, it takes longer because the pin chambers on 1960s hardware are often worn beyond the point where a standard rekey kit seats cleanly. In those cases we recommend a cylinder replacement, quoted before any work begins.
When Rekeying Beats Replacement
If your existing locks are in decent mechanical shape, rekeying is the smarter spend. You keep hardware that matches the rest of the door, get fresh key control, and avoid paying for new deadbolts that may not fit the existing mortise pockets on a mid-century La Cañada Flintridge home. If the cylinder is too worn to rekey, we’ll tell you and show you why before recommending replacement.
Rekey Service in La Cañada Flintridge
Rekey Service in La Cañada Flintridge is the full-scope job: inventory every exterior cylinder on the property, rekey all of them to a single new key, test each lock, and hand you the working set. Most LCF homes have three to five exterior doors. Garage side doors, back patio doors, the front door, and a service entrance. They are rarely the same brand. Decades of piecemeal repairs leave a house keyed three different ways, and our job is to make one key rule all of them. Whole-house rekey service runs $150 to $350 depending on cylinder count and wear.
Multi-Door, Mixed-Brand Jobs
We rekey Kwikset, Schlage, Yale, Baldwin, and Medeco cylinders to the same key when the keyways allow it. Some combinations cannot share a key profile, and we will tell you that up front rather than promise a setup that will not work. The written quote includes every cylinder we can see. If we find a hidden door with a different lock, we stop and re-quote before touching it.
Mortise Lock Experience
La Cañada Flintridge’s mid-century homes are full of original mortise locks. These are not the quick swap-out jobs a tech with only modern deadbolt training can handle. We service and rekey mortise cylinders regularly here. If the pin chamber is too worn to hold a fresh rekey, we quote a replacement cylinder with an ANSI Grade 1 rating, which is the same standard our Commercial Locksmith in La Cañada Flintridge uses on commercial buildings.
Trusted Brands We Service in La Cañada Flintridge
We are trained and equipped to service Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware. For La Cañada Flintridge work, the brands we see most are Kwikset and Schlage on mid-century homes, Yale on newer builds, and Baldwin on higher-end remodeled properties. We stock pins, springs, tailpieces, and common cylinders locally so a rekey on Descanso Drive does not wait on a courier. If you have a Medeco or high-security cylinder, the rekey cost runs higher because the pinning process is more involved and the key blanks are restricted.
Common Rekey Locks Problems We See in La Cañada Flintridge Homes
- Worn mortise pin chambers: Original 1950s and 1960s mortise locks in LCF often have pin chambers so worn that a fresh rekey will not hold reliably. Forcing standard pins into a wallowed-out chamber damages the cylinder. We check this before rekeying and quote a replacement if needed.
- Mismatched brands across doors: Three to five exterior doors on one La Cañada Flintridge property frequently carry different lock brands from decades of piecemeal fixes. A rekey quote should inventory every cylinder first. Ours does.
- Worn 1960s keyways on Schlage and Kwikset: Original hardware that has been in daily use since the Johnson administration sometimes has a keyway so worn that new pins will not seat correctly. The cylinder needs replacement, not new pins. We diagnose this before any work starts, not after dispatch.
- Multiple keys floating around after a sale: La Cañada Flintridge homes change hands with no reliable record of who has key copies. Neighbors, contractors, cleaners, pet sitters, a relative who borrowed a key years ago. Rekeying restores key control in under two hours for most properties.

High-security cylinders like Medeco or Mul-T-Lock run higher, typically $35 to $65 per cylinder for the rekey alone because of restricted blanks and tighter pinning tolerances.

FAQs About Rekey Locks in La Cañada Flintridge
Plan on 60 to 90 minutes for a three-to-five-door house with standard Schlage or Kwikset cylinders. Mortise locks, worn cylinders, or mixed high-security hardware can push that to two hours or more. We will give you a time range on the phone and a live trackable arrival time before the tech heads your way. Call (409) 405-4485 to schedule and get a written price.
We rekey mortise locks. La Cañada Flintridge’s mid-century homes are full of them, and a tech who only knows modern deadbolts will either refuse the job or charge you for a cylinder they cannot properly service. We rekey or replace mortise cylinders on the spot, and we quote the work before starting. If the cylinder is too worn, we recommend a replacement and show you why.
Usually, yes. Kwikset, Schlage, Yale, and many Baldwin locks can be rekeyed to the same key profile when the keyways are compatible. Some combinations will not match, and we will tell you that before quoting work that cannot hold. Getting one key to rule every exterior door on your La Cañada Flintridge home is the goal, and the written estimate covers every cylinder we inventory up front.
Before the tech arrives, you get their name, a live trackable arrival time, and confirmation that they are background-checked and in uniform. They arrive in a company vehicle. The price is already in writing. The tech sends before-and-after photos of the work, and you get a digital invoice with a pay link. No anonymous subcontractor, no mystery bill. This is the Relay Visibility Guarantee, and it is on every job we do in La Cañada Flintridge.
Rekeying is cheaper than replacing hardware when the existing locks are in sound mechanical shape. A rekey runs $25 to $45 per cylinder versus $45 to $120 or more for a new deadbolt, plus labor. On a home with original mid-century hardware, replacement often means new mortise pockets and door prep, which adds cost fast. Rekeying preserves the hardware that fits your doors and restores key control for far less. If a cylinder is too worn to rekey, we will quote the fix honestly before any work starts. Call (409) 405-4485 for a free estimate.
