Fast, Reliable Rekey Locks Across Kensington
If you’ve just bought a home in Kensington, had a tenant move out, or lost track of who holds keys to your front door, a professional rekey is the fastest way to restore control over your locks. A typical residential rekey in Kensington runs $75 – $160 for the first lock and $15 – $25 per additional cylinder, with most homes finished inside an hour and a half. We serve all of Kensington including the hillside streets off Arlington Avenue, the flats near Colusa Circle, and the neighborhoods around Kensington Park. Call (956) 275-7388 and a live person answers, day or night.
Rekeying means changing the internal pins inside your existing lock cylinders so the old keys stop working. You keep the hardware you already have. New keys are cut on the spot. No drilling, no drywall dust, no new holes in your door.
In Kensington, that distinction matters more than in most places. The housing stock here runs heavily toward homes built in the 1920s through the 1950s, and many of those doors still carry their original mortise lock bodies. Those locks are often better built than anything you can buy at a big-box store today, which is why a rekey, not a replacement, is usually the right call. More on that below.
Why Ridley Locksmith & Security Is Kensington’s Preferred Rekey Locks Company
We are not a call center. When you call Ridley Locksmith & Security, you reach a live person who works for the company, and the technician who arrives at your Kensington door is a background-checked, uniformed employee, not a subcontractor dispatched from a parking lot. That matters when you’re handing over every key to your house.
Ridley Locksmith & Security is independently owned and operated, and has been part of the Garrison Partners family since 2007. Every job we run in Kensington, whether it’s a single cylinder Rekey Locks job or a full five-lock keyed-alike conversion on a 1930s bungalow, operates under The Garrison Standard. That’s a written code covering how the price is set, how the work is performed, and what happens if something goes wrong. It’s not a slogan. It’s the document we hand you before any tool comes out of the van.
Kensington homeowners tell us the same thing over and over: they’ve been burned by a locksmith who quoted one price on the phone and a different price at the door, or who finished the job and vanished. We run a written price before work begins, every time, and we back the repair with a written guarantee for one full year. If the work fails inside that window, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s automatic on every rekey in Kensington.
Rekey Service in Kensington
Rekey Service in Kensington is the job we run most often: removing the lock cylinder, replacing the internal pin and tumbler stack, and cutting a new key so every old key stops working immediately. Kensington homeowners call for this after a tenant turns over a rental near the Contra Costa College corridor, after a contractor or housekeeper hands back a key, or after a divorce or roommate change leaves questions about who else can still get in. In a Kensington hillside home where the front door faces Arlington Avenue and the back door opens to a canyon, you want every exterior cylinder pinned to one new key, fast.
The work does not require replacing your lock hardware. The cylinder is pulled, re-pinned, and reinstalled. The whole process usually takes 15 – 20 minutes per lock. Total cost for a typical Kensington home with two or three exterior doors lands between $105 and $210.
Rental Turnover Rekeys
Kensington has a steady churn of rentals, particularly in the mid-century apartments and duplexes around Colusa Circle and the flats below the hillside. When a tenant leaves, you need the locks rekeyed the same day, not next week. We run rental turnover rekeys with written documentation for every cylinder, so the property owner has a record of who holds keys and when the work was done.
Locks Against Lost Keys
If a key went missing, rekeying beats replacement on cost and on hardware quality. A rekey in Kensington runs $75 – $160 for the first cylinder and $15 – $25 for each additional one, compared with $120 – $300 per lock for full hardware replacement. Most Kensington homes we see have original hardware worth keeping.
Keyed Alike in Kensington
Keyed Alike in Kensington means pinning every lock in your house to the same key, so one key operates the front door, the back door, the side gate, and the garage door into the house. That’s not a convenience trick; it’s a real simplification for older Kensington homes where occupants have spent years juggling a front-door key, a back-door key, and a deadbolt key that all look identical on a ring.
Keyed alike pricing in Kensington runs $15 – $25 per cylinder to pin after the first cylinder’s rekey is covered, so a three-door home typically lands between $135 and $235. If you want the front door and back door on one key but the garage interior door on a second key, we can do that too, and we’ll hand you a written key schedule so you know exactly what opens what.
One Key for the Whole House
The old keys stop working the moment the new pins are loaded. We cut the new keys on site, test every cylinder in front of you, and hand you the written guarantee covering the work for one full year. No more fumbling at the back door in the dark while the front door key sits useless on the same ring.
Selective Keying for Multi-Unit Buildings
Kensington has a number of small multi-unit buildings, particularly the older courtyard apartments tucked off the Arlington corridor. We can pin common-area locks and individual unit locks to different keys, or set up a simple master key system, so a building owner carries one key while each tenant carries another. The written key schedule we provide tells you exactly which key operates which door.
Trusted Brands We Service in Kensington
We work on Kwikset and Schlage hardware more than any other brands in Kensington, because those are the cylinders most often retrofitted into the older mortise lock bodies in this area. We also carry Medeco and Yale cylinders and pins for high-security rekeys, which we see on Kensington doors where a previous owner upgraded to a restricted keyway. Because we stock parts for these brands on the van, we rarely need to leave a Kensington job to chase a part. That means the rekey gets finished in one visit, not two.
Common Rekey Locks Problems We See in Kensington Homes
- Corroded or seized mortise lock bodies. Kensington’s older homes often have original mortise locks, and decades of coastal fog and damp air from the Bay can corrode the internal mechanism. A rekey won’t fix a failing lock body, and a technician who quotes one price over the phone and then discovers a seized lock has two choices: force the job or level with you. We level with you before any work starts.
- Painted-over cylinders. When a Kensington house gets repainted, painters often spray right over the lock cylinder and escutcheon. Removing that cylinder cleanly takes patience. Rushing it scores the finish or cracks the trim plate, and then you’re paying for a replacement you never needed.
- Sight-unseen quotes that shift on arrival. Some outfits quote a flat rekey price over the phone, then arrive and declare the hardware is too old, too odd, or too far gone, and the only option is full replacement. That’s the bait-and-switch. We give you a written price before any work starts, and we never change it at the door.
- Mixed keyways from decades of patchwork fixes. A Kensington house that’s been through two or three owners often has Schlage on the front door, Kwikset on the back, and an original mortise cylinder on the side door. Those keys don’t interchange. We can pin all three to one key if the cylinders are in good shape, which is the fastest path to a single working key ring.
Pricing for Rekey Locks in Kensington, CA
Here’s what a rekey in Kensington actually costs. The first cylinder rekey runs $75 – $160. Each additional cylinder runs $15 – $25. A typical three-door home lands between $105 and $210.

FAQs About Rekey Locks in Kensington
Yes. We’ll ask how many exterior doors you have, what brands you can see on the face of the lock, and the approximate age of the house. From that, we’ll give you a firm price range in writing before anyone is dispatched. That written price is what you pay, and it’s the price on the invoice. Call (956) 275-7388 for your exact quote.
A rekey works on most older Kensington hardware, including the original mortise locks in many 1920s through 1950s homes. Those lock bodies are often built better than modern big-box hardware. If the cylinder itself is in good shape and the mechanism turns, we can rekey it. If the lock body is corroded or seized, we’ll show you what’s wrong and quote a repair or replacement before doing anything.
Keyed alike means every lock you choose is pinned to the same key. For a Kensington home with three or four exterior doors, it’s absolutely worth it: one key instead of a ring full of look-alike keys, and no standing in the dark trying to find the back door key. The cost is a few dollars per cylinder to pin, and we cut all new keys on site.
A typical two- or three-door rekey in Kensington takes 45 – 90 minutes. We rarely need to drill. Drilling only becomes necessary if a lock is severely seized or a cylinder can’t be pulled because it’s been painted over and is genuinely stuck. Even then, we’ll tell you before we drill and give you the replacement cost in writing first.
Every technician we send to Kensington wears a Ridley Locksmith & Security uniform, drives a marked van, and carries company ID. You’ll know the name of your technician before they arrive, and you can call our dispatcher at any time to confirm who’s coming to your door. We don’t use subcontractors, and we don’t send unmarked vehicles.
