Fast, Reliable Rekey Locks Across Atherton
Rekeying locks in Atherton starts with a simple fact: the work itself usually takes 20 to 40 minutes per cylinder, and the full price should be agreed on the phone before our van passes your gate. We’re Ridley Locksmith & Security, and we’ve been operating to The Garrison Standard since 2007. When you call (956) 275-7388, a live person picks up, asks about your doors and hardware, and gives you a written price range for the job. No call-out surcharge added on arrival. No price that shifts when the tech steps out of the van. Just a straight answer about what a Rekey Locks job will cost in Atherton, and when we can be there.
Why Ridley Locksmith & Security Is Atherton’s Preferred Rekey Locks Company
Atherton homeowners don’t call a locksmith casually. Most homes here sit well back from the road, behind gates or long private lanes off Atherton Avenue, Alameda de las Pulgas, or El Camino Real. The person you let through that gate is the person touching every lock cylinder on your house. That’s why every Ridley technician is background-checked, uniformed, and dispatched in a marked vehicle with verifiable company credentials. We don’t use subcontractors. The tech who shows up at your driveway is the same person whose identity you can confirm before you open the gate.
Drew Kowalski leads our team, and he’s built the operation around one thing: a written price before any work starts, and a written guarantee covering every repair for one full year. Atherton customers who’ve had us rekey after a sale, a housekeeper transition, or a contractor project routinely tell us the same thing: knowing the invoice will match the quote changes the whole experience. That’s not a marketing line. That’s The Garrison Standard, and it’s been how we operate since 2007.

Lock Rekey in Atherton
A Lock Rekey in Atherton means changing the internal pin and tumbler configuration inside your existing lock cylinder so old keys stop working, without replacing the hardware itself. For a town with as many large-lot custom homes and mid-century ranches as Atherton, rekeying is almost always the smarter first move over swapping hardware. The brass Schlage or Kwikset cylinders on older Atherton doors are typically solid. What’s not solid is knowing who holds copies of the keys. A rekey fixes that for a fraction of what full hardware replacement costs.
Standard Cylinder Rekey
Most Atherton rekey jobs involve Schlage or Kwikset pin and tumbler cylinders, sometimes Baldwin on higher-end front entries. We pull the cylinder, re-pin it to a new key, and test the action before reinstalling. This usually runs $25 to $40 per cylinder depending on the hardware type and condition, and it’s the most common request we handle in Atherton.
High-Security Cylinder Rekey
When a home runs Medeco, Mul-T-Lock, or Abloy cylinders, the rekey process is more involved. These are restricted keyways that require proof of ownership before any work proceeds. Rekeying high-security cylinders in Atherton typically runs $35 to $65 per cylinder, and it’s worth every dollar if you’re securing a property that’s had staff, contractors, or previous owners with key access.
Locksmith Rekey in Atherton
A Locksmith Rekey is the same mechanical job performed by a vetted, credentialed professional who can also assess whether your existing deadbolt is actually doing its job. In Atherton, we regularly find homes where the lock body says Kwikset or Schlage but the deadbolt is an older, non-hardened model that a re-pinned cylinder can’t fix by itself. A legitimate rekey from a trained locksmith includes that assessment: re-pin the cylinder, yes, but also tell you plainly if the strike plate or deadbolt needs attention. That’s the difference between a rekey and a security upgrade.
Residential Lock Rekey
For Atherton homes, a residential rekey usually means multiple cylinders: front door, back door, garage entry, sometimes a detached pool house or ADU. Most jobs run $120 to $280 total for a typical Atherton property depending on cylinder count. We quote the full scope on the phone, before anyone is dispatched.
Commercial and Estate Rekey
Larger Atherton properties, including estates with guest houses or staff quarters, often benefit from a master key system installed at the same time as a rekey. That means one key for the owner that opens everything, and restricted keys for staff that only open what they need. We survey these jobs before quoting because the cylinder count and access points vary widely. Every quote is a written price, not a ballpark.
Trusted Brands We Service in Atherton
Most Atherton homes have Schlage, Kwikset, or Yale hardware, with Baldwin on higher-end custom builds. We carry pin kits, cylinders, and common replacement parts for all of these on our service vehicles, so a rekey in Atherton rarely requires a second visit for parts. When the hardware runs high-security lines like Medeco or Mul-T-Lock, we have the training and authorization to rekey those cylinders correctly, and we’ll verify ownership before touching the lock. That’s not an inconvenience; it’s how restricted keyways are supposed to be handled.
Common Rekey Locks Problems We See in Atherton Homes
- Old keys still circulating after a sale. Atherton properties change hands regularly, and the previous owner’s family, staff, and contractors often still hold copies. A rekey is the only way to retire every one of those keys at once.
- Hardware that was never re-pinned after construction. Many Atherton homes built in the mid-century boom still run their original Schlage or Kwikset cylinders, which means dozens of people have potentially held working keys over the decades.
- Gated driveway complications. Because so many Atherton homes sit behind gates, some out-of-town locksmiths quote a low per-lock price then add gate, distance, or “after-hours” fees once they arrive. We quote the whole job up front, including gate access.
- Mismatched cylinder types across one property. Atherton homes often have a mix of hardware: Schlage on the front door, Kwikset on the back, a Baldwin on a side entry. Rekeying all of them to a single key is a straightforward job, but it requires a tech who recognizes the difference and has the right pins on the truck.

FAQs About Rekey Locks in Atherton
Ask for the tech’s company ID and vehicle number before opening the gate. Every Ridley technician carries company credentials and arrives in a marked vehicle. You can also call (956) 275-7388 while the tech is at the gate and confirm the dispatch directly with our office. A live person will answer and verify the technician’s name and assignment in seconds.
No. Gate access, driveway length, and property size are all factored into the quote we give you on the phone before dispatch. If we quote $180 for a three-cylinder rekey behind a gate, that’s the invoice total. Some out-of-town shops quote a teaser per-lock price and then add gate or distance fees on arrival. We don’t do that, and we never have. Call (956) 275-7388 for a straight quote.
In most cases, yes. Older Schlage and Kwikset cylinders are built well and rekey cleanly. We’ll inspect the cylinder and the deadbolt while we work. If the deadbolt is tired or the strike plate is loose, we’ll tell you and give you a written price for the fix. But if the cylinder itself is sound, a rekey is all you need. New hardware is rarely required on Atherton’s mid-century homes.
A typical four-to-six-cylinder home rekey in Atherton takes 60 to 90 minutes on site. Add a detached pool house or ADU with another two to three cylinders, and you’re looking at two to two and a half hours. We’ll give you a time window on the phone that accounts for your specific door count. The price is set before we arrive, and the clock doesn’t change it. Call (956) 275-7388 to schedule.
Yes, and doing it during a rekey is the most cost-efficient time. We can re-pin cylinders to a master key layout in the same visit, which means the family key opens everything while staff or service providers get restricted keys for specific doors only. Atherton estates with guest houses or staff quarters use this setup often. We’ll survey the property and give you a written scope with a flat per-lock price before any work begins. Call (956) 275-7388 to arrange a survey.
