Why Ridley Locksmith & Security Is Petaluma’s Preferred Rekey Locks Company
Ridley Locksmith & Security is part of the Garrison Partners family, operating to The Garrison Standard since 2007. That means every technician who shows up at a Petaluma address is background-checked, uniformed, and held to a written code of conduct, not just a vague promise. We don’t subcontract work to unknown crews, and we don’t run an answering service. A live person answers our phone 24 hours a day, 7 days a week.
Our local reputation in Petaluma is built on the 365-Day Done Right Promise: if the rekey doesn’t work right inside a full year, we come back and fix it at no charge. That guarantee is written on every job, not spoken. Petaluma homeowners tell us the same thing again and again: they’ve been burned by a tech who quoted one number on the phone and a different number at the door. We address that directly. Drew Kowalski, who leads our team, insists on a written price before any work begins, every single time.
We know Petaluma’s housing stock. We know what’s behind the front doors on Keller Street and the commercial strips on Petaluma Boulevard. That local knowledge changes how we quote, how we stock our vans, and how fast we can get a rekey done right.
Rekey Service in Petaluma
Rekey Service in Petaluma means changing the internal pins inside a lock cylinder so the old keys no longer turn it, while keeping the existing hardware on the door. A rekey on a standard Schlage or Kwikset deadbolt in Petaluma runs $95 – $150 per cylinder. When the job involves an original mortise lock body on an older west-side home, the price is $180 – $320 because the cylinder has to be pulled, disassembled, re-pinned, and reinstalled with more care. No hardware gets replaced unless you ask for it.
Mortise Lock Rekeying
Many Petaluma homes from the 1900s and 1910s still have their original mortise locks, especially in Oakhill-Brewster and the A Street Historic District. These aren’t bored-cylinder deadbolts. They take longer to rekey and require a tech who’s actually worked on them before. Our technicians are trained on this hardware, and we keep the right pin kits in our vans for it.
Deadbolt and Entry Knob Rekeying
For newer Petaluma construction, standard deadbolts and entry knobs from Schlage, Kwikset, and Yale are the common case. We re-pin these quickly, usually within 30 – 45 minutes on site, and we’ll key them to match an existing key if you’d prefer not to carry a new one.
Keyed Alike in Petaluma
Keyed Alike in Petaluma means re-pinning multiple locks so one key operates all of them. A typical Petaluma job involving a front door, back door, and one deadbolt costs $220 – $380, depending on whether the cylinders are standard or mortise. This is one of the most popular services we do for Petaluma homeowners who’ve just closed on a house and want to know exactly who has working keys. One key for every exterior door, old keys dead, done in a single visit.
Post-Closing Keyed Alike
When you buy a house in Petaluma, you don’t know how many copies of the old key are floating around. The seller, their agent, a contractor, a neighbor who watered the plants. Rekeying every exterior lock to one new key eliminates that question. We do these jobs same-day or next-morning throughout Petaluma.
Landlord and Rental Keyed Alike
For Petaluma landlords, keyed alike simplifies turnover between tenants. We can rekey all exterior doors to a single key, and when a tenant moves out, we rekey again so the old key goes dead. It’s faster and cheaper than replacing hardware, and it keeps your existing locks intact.
Trusted Brands We Service in Petaluma
We rekey and service hardware from Kwikset, Schlage, and Yale, plus high-security lines including Medeco and Baldwin. For Petaluma’s older homes, we stock common cylinder profiles and pin kits for original mortise locks that big-box stores don’t carry. That means we show up ready to work, not ready to order parts. When a Petaluma door has a Baldwin mortise lock or a Medeco high-security cylinder, we don’t swap it for cheaper hardware. We rekey what’s there and keep it functional.
Common Rekey Locks Problems We See in Petaluma Homes
- Mortise cylinders rekeyed with the wrong pin lengths. Big-box rekey kits are built for modern bored-cylinder locks. When someone uses one on an antique Petaluma mortise cylinder, the pins bind the plug and the lock jams within a week. Unfortunately, we’ve been called to undo that exact damage more times than we can count.
- Antique mortise locks need rekeying, not replacement. Homeowners on the west side of Petaluma are sometimes told their original hardware is “too old” and needs to be replaced. That’s often wrong. A tech who knows this hardware can pull the cylinder and re-pin it without touching the lock body or the door. Replacement is only needed when the lock body itself has failed.
- A second keyway on the same door gets missed. Older Petaluma rentals often have a separate landlord lock or a keypad entry added to the same door. If you rekey only one cylinder, the old key still works in the other. We check every door and every keyway before we call the job done.
- Poorly installed smart lock keypads. Many Petaluma homes have smart locks or keypads added to original doors. When the mechanical cylinder under that keypad isn’t rekeyed along with the deadbolt, the old key still works. We rekey both so the door is actually secure.

We don’t add a call-out surcharge when the tech arrives, and we don’t “discover” problems that change the number unless you approve the written change before we do the work.

FAQs About Rekey Locks in Petaluma
You don’t have to replace it. Most original mortise locks in Petaluma’s older homes can be rekeyed by pulling the cylinder and re-pinning it, which costs $180 – $320. Replacement is only necessary if the lock body itself is cracked, seized, or otherwise mechanically failed. We’ll tell you which situation you have before any work starts. Call (956) 275-7388 and we’ll walk through what’s on your door.
Because we give you a written price before dispatch. When you call (956) 275-7388, we’ll ask about your doors, the lock brands, and whether they’re mortise or standard. We then give you a firm number. That number is the price on the invoice. No tech arrives to “discover” anything that changes the price. If the scope changes, you’re handed a written new price and you approve it before we touch a screw.
Most standard rekeys take 30 – 45 minutes per cylinder once the tech is on site. A simple two-door, keyed-alike job is typically done in under an hour. Mortise lock rekeying on older Petaluma homes takes longer, usually 1 – 2 hours for a front-and-back combo. We schedule a specific window and stick to it. Call (956) 275-7388 to book a time that works.
Have every key you want to keep or match, plus your ID to verify you’re the homeowner or the person authorized to request the rekey. If you’re a renter, check your lease: most require landlord permission before a rekey. We’ll verify ownership or authorization on site. The whole thing takes two minutes and keeps everyone honest.
Yes. Many Petaluma homes have smart locks or keypad entry added to original doors. We rekey the mechanical cylinder inside those units so the old physical key stops working, while leaving the keypad and digital functions intact. That runs $120 – $220 per unit. We also rekey the standard deadbolt alongside it, so one new key works across the whole door. Call (956) 275-7388 for a firm price on your setup.
