Fast, Reliable Rekey Locks Across Sausalito
Rekeying locks in Sausalito typically costs $25 – $45 per cylinder, and most homes with two or three doors are done in under an hour. That’s the honest range: the written price you get on the phone is the price on the invoice, before anyone jumps in a van. Preston Locksmith & Security has been doing this work since 2008, and we know Sausalito’s quirks better than most: the stair streets off Bridgeway, the floating-home docks, the salt air that eats lock cylinders faster than inland Marin. Call (409) 405-4485, tell us what’s on the door, and we’ll lock in a firm price. Then a background-checked, uniformed tech arrives when we say they will, with a live tracking link so you can watch the whole drive.
Why Preston Locksmith & Security Is Sausalito’s Preferred Rekey Locks Company
Sausalito is not an easy town to be a locksmith in, and that’s exactly why we’re good at it. Half the homes here require local knowledge just to find the front door: a gate code off a stair street, a dock number on a floating home, a parking spot on a hill too steep for parallel parking. We settle those logistics before dispatch, so the tech doesn’t burn 20 minutes wandering and you don’t get a surprise “trip fee” because the address was ambiguous. That’s the Relay Visibility Guarantee at work: a written price before work begins, a live trackable arrival time, before-and-after photos of every job, and a written guarantee on every repair.
Our customers in Sausalito consistently tell us the same thing: they called because the price was real, the person who showed up matched the photo, and the rekey was done before lunch. Kevin Yoon, who leads our team, trains every tech to treat a Sausalito job as if the neighbor is watching. Because in this town, the neighbor usually is. We’re independently owned and operated, part of the Relay Home Co. family, and we answer the phone with a live person 24/7. No voicemail trees, no callbacks at 2 a.m., no phone tag.
Rekey Deadbolt in Sausalito
Rekey Deadbolt work in Sausalito means pulling the cylinder from the deadbolt, replacing the internal pins and springs so old keys stop working, and handing you a new set of keys without changing the hardware. It’s the fastest and most affordable way to confirm that whoever had the old keys no longer has access. In Sausalito, a standard single-cylinder deadbolt rekey runs $25 – $45, and a double-cylinder deadbolt costs a bit more because the cylinder has to be removed from both sides. If the deadbolt is a Baldwin, Medeco, or high-security cylinder, the pin work is more precise and the range lands at the top of that band.
When a deadbolt rekey isn’t enough
Salt air off the bay gets into lock cylinders through the keyway and corrodes the pins, springs, and plug face. We see it constantly on exterior doors along Bridgeway and the waterfront flats. If the cylinder is seized or the key turns stiffly, we’ll inspect the pins and tumbler stack and tell you whether fresh pins are enough or the cylinder itself should be replaced. The rekey price doesn’t change without your okay.
Deadbolt hardware we handle
We carry pin kits and tailpieces for Schlage, Kwikset, Yale, and Baldwin deadbolts in the van, so most Sausalito deadbolt rekeys are a single visit. If you have a Medeco or Mul-T-Lock high-security deadbolt, the key control is registered to you, and the rekey includes new key cards and pinning that can’t be duplicated at a hardware store.
Rekey House in Sausalito
Rekey House service in Sausalito covers every keyed entry point you want on one key: the front door, back door, side gate, garage entry, and any interior door with a key. You decide the scope, and we rekey each lock’s cylinder to match a single new key, or create a master key setup if you’d like one key for you and a restricted key for a cleaner or housesitter. The cost is per cylinder, not a flat mystery fee, so a typical Sausalito house with four keyed entries runs $100 – $180 total, all in, with the written price confirmed before the first tool comes out.
New homeowners: cover every access point
We see it too often: a new owner in Sausalito rekeys the front door but forgets the dock locker, the back gate off the stair street, or the garage side door. The old keys still work, and the person who had them knows the house. Rekeying one door doesn’t change who has access unless every keyed entry is rekeyed to the new key. Tell us you’ve just closed, and we’ll walk the property with you and list every keyed entry before we quote anything.
Salt-air locks need more than a pin swap
Every rekey we do in Sausalito includes a cylinder and pin inspection, because the bay air accelerates corrosion on exterior hardware. A pin swap alone on a corroded cylinder is a temporary fix: the new pins will stick, and the lock will fail within months. We’ll show you before-and-after photos of the cylinder, so you can see what we saw. That’s part of the Relay Visibility Guarantee: no mystery about what happened inside the lock.
Trusted Brands We Service in Sausalito
We stock parts and pin kits in the van for the brands Sausalito doors actually wear. Kwikset is the default on most hillside rentals and older floating homes. Schlage shows up on newer builds and remodeled entryways. Medeco and Baldwin appear on higher-end homes up in the hills, where owners want restricted keys and stronger deadbolt throws. Yale is common on older mid-century homes. Whatever’s on the door, we carry the pin depths, spring tensions, and tailpieces needed to rekey it right the first visit, and we’ll tell you honestly if the hardware is too corroded to be worth saving.
Common Rekey Locks Problems We See in Sausalito Homes
- Salt-air corrosion on exterior cylinders. The bay’s moisture and salt work into the keyway and seize the pins. We open the cylinder, clean the plug, inspect the springs, and replace anything that won’t hold tension. A rekey on a corroded cylinder without this inspection is a waste of your money.
- Address ambiguity on stair streets and docks. A house on a stair street off Bridgeway or a floating home with a dock number is not where a delivery driver expects it to be. We confirm gate codes, dock numbers, and parking before dispatch so the tech doesn’t burn the arrival window and the quoted price holds.
- Partially rekeyed homes after a sale. New owners rekey the front door and stop there, leaving the back gate, dock locker, or garage on old keys. We list every keyed entry before quoting, so you know what one key will actually control.
- Worn pin stacks that make old keys work too well. An old lock with worn pins sometimes accepts keys it should not, which is a quiet security problem. Rekeying with fresh pins eliminates that slop and tightens the key feel back to factory tolerance.
Pricing for Rekey Locks in Sausalito, CA
Rekeying in Sausalito runs $25 – $45 per cylinder for standard Schlage, Kwikset, Yale, or Baldwin locks. High-security cylinders like Medeco or Mul-T-Lock land at the top of that range, because the pinning is specialized and the new keys are registered to you. A typical four-entry house rekey runs $100 – $180. A single deadbolt rekey runs $25 – $45. These are the numbers, and they do not change between the phone call and the invoice: the price is in writing before anyone is dispatched, and no call-out surcharge appears when the tech arrives. If salt-air corrosion has seized a cylinder and it needs replacement, you’ll see the before-and-after photos and approve the additional cost before it’s done.

FAQs About Rekey Locks in Sausalito
Call us at (409) 405-4485 and describe every keyed entry point: front door, back door, gate, dock locker, garage. We quote a per-cylinder price and a total range while you’re on the phone, and that written price is the final price. No dispatch fee, no arrival surcharge, no “it’s worse than we thought” add-on unless we show you photos and you approve it. That’s the Relay Visibility Guarantee on every job.
Sometimes, and we’re honest about it. If the cylinder is corroded and the pins are seized, the rekey includes a clean-and-inspect of the cylinder and plug. If the cylinder is too far gone, we’ll show you photos and tell you the replacement cost before touching it. Most Sausalito homes near the waterfront need a cylinder inspection at minimum, which is included in the original quote. Call (409) 405-4485 and we can tell you over the phone what to expect, based on where your door sits and how old the lock is.
You get the tech’s name and photo before they arrive, and a live tracking link that shows their vehicle moving toward you in real time. The tech arrives in uniform, with a Preston Locksmith & Security ID. Before any work starts, you get a written price, and after, before-and-after photos of the lock. If the person at the door doesn’t match the photo, don’t let them in. But they will.
No. If a house has four keyed entries and you rekey one, the other three still open for whoever held the previous keys. Rekeying one door is the most common security gap we see in Sausalito after a sale, especially with back gates off stair streets and dock lockers on floating homes. We walk every keyed entry with you and quote the full rekey, then you decide what to include. The point is that after the job, one new key controls everything you choose, and the old keys don’t open anything. Call (409) 405-4485 for a free walkthrough and written price.
A standard four-entry house rekey takes 45 to 60 minutes. What disrupts it in Sausalito is the address: a stair street with no parking, a floating-home dock with a locked gate, or a gate code that wasn’t shared at booking. That’s why we confirm docking, parking, and gate codes before the tech leaves, so the clock doesn’t run out while they search for the door. The work itself is quick; the Sausalito part is knowing where the door actually is.
