Fast, Reliable Rekey Locks Across Redwood City
Rekeying a lock in Redwood City typically runs $25 – $45 per cylinder for standard Schlage or Kwikset hardware, and most homes are done in under an hour. That’s the honest range we quote before a single tool leaves the bag. If you just moved into a place off Woodside Road or you’re handing keys to a new tenant near Sequoia Station, call (409) 405-4485 and we’ll walk you through exactly what your doors need.
Redwood City’s housing stock is unusually mixed for its size. Blocks of pre-war downtown bungalows and mid-century Eichler-style tracts sit within a mile of newer mid-rise and townhome builds off El Camino Real. A rekey quote here often depends on whether the door carries a builder-grade Kwikset pin and tumbler or an older mortise lock that needs its own cylinder work. That’s why we confirm the lock type before promising a per-door price, and why the price on the phone is the price on the invoice.
Our Rekey Locks team covers every corner of Redwood City, from the 94061 flats to the hills above Farm Hill Boulevard. We’re a Bay Area crew that knows this city’s doors. You’ll get a written price, a live trackable arrival time, and before-and-after photos of every job. No anonymous techs in an unmarked van, no bill that swells between the estimate and the invoice.
Why Preston Locksmith & Security Is Redwood City’s Preferred Rekey Locks Company
Rekeying sounds simple until you’re staring at a door with mismatched hardware and a deadbolt that hasn’t been touched since the Nixon administration. That’s the kind of thing we see regularly in Redwood City. Founded in 2008 and run by Kevin Yoon as part of the Relay Home Co. family, Preston Locksmith & Security has built its Redwood City reputation on a simple rule: the price is in writing before any work starts, and it stays that way.
Every technician who arrives at a Redwood City door is background-checked and in uniform. You know who is coming, what they look like, and exactly when they’ll knock, because The Relay Visibility Guarantee puts a live trackable arrival time on your phone. Before-and-after photos document the work. A written guarantee stamped on every repair means if a rekey fails within 365 days, we make it right under the 365-Day Done Right Promise, including a free second visit.
Kevin Yoon runs a team trained on Medeco, Mul-T-Lock, Abloy, Baldwin, and Sargent hardware, alongside everyday Schlage, Kwikset, and Yale. That matters in Redwood City, where a 1940s downtown bungalow and a 2015 townhome off El Camino Real call for very different lock work. We quote for what you actually have, not what a call-center script assumes.
Keyed Alike in Redwood City
When a Redwood City homeowner asks us to key every exterior door to one key, the job involves pulling each lock cylinder, swapping the internal pins so the old keys stop working, and setting every cylinder to the same pin configuration. It’s the fastest way to simplify a key ring without replacing hardware. You keep the same locks; only the pins change. For a standard three-door home, keyed alike service in Redwood City typically runs $75 – $135 total, depending on whether we’re working with one brand or a mix.
Single-Key Convenience
On a call in the Mount Carmel neighborhood, a homeowner handed us keys from a recently vacated rental and wanted every exterior door set to one key. We pulled the original Kwikset and Schlage lock cylinders, changed the pins so the old tenant keys stopped working, and keyed the deadbolt and knob alike on three doors in one visit. Nothing was drilled. The homeowner kept the same hardware and only paid for rekey labor and pins.
For Redwood City landlords near Sequoia High School, keyed alike is the standard between-tenants move. It gives you one key for the front door, side door, and garage service door, and it eliminates the neighbor-with-a-spare-key problem entirely. We can also set up a master key system if you manage multiple units in a duplex or fourplex off Middlefield Road.
Mismatched Hardware
A call we get more than you’d expect: a Kwikset knob and a Schlage deadbolt on the same door. Different brands use different keyways, so you can’t key them alike without swapping one cylinder. We tell you that on the phone, not after we arrive. The cylinder swap adds roughly $20 – $35 to the job, and the total is locked in writing before we dispatch.
Rekey Deadbolt in Redwood City
Rekeying a deadbolt in Redwood City means changing the pins inside the cylinder so the old key no longer turns it. New keys, same deadbolt, no new hole drilled. For a single deadbolt, expect $25 – $45 on a standard Schlage or Kwikset. If your deadbolt is a high-security Medeco or Abloy cylinder, expect $45 – $75 per cylinder for the rekey plus any restricted key blanks, which we quote before we touch the door.
After a Move or Tenant Change
You closed on a house near Red Morton Park, or you just turned over a rental unit near Cañada College. You don’t know who has copies of the keys. Rekeying the deadbolts is the first thing we recommend. It’s cheaper than replacing the hardware, gives you fresh keys that nobody else holds, and takes about 15 to 20 minutes per deadbolt. We’ll also check that the deadbolt actually throws fully into the strike plate while we’re there.
When Rekeying Isn’t the Fix
Homeowners sometimes call for a rekey expecting it to fix a door that won’t latch or a deadbolt that grinds. In Redwood City’s older downtown bungalows, that’s frequently a strike plate misalignment, not the cylinder. Multiple layers of paint over seven decades shift the door slab enough that the latch misses the strike entirely. We’ll tell you if the real problem is alignment and quote you an honest fix instead of selling you a rekey you don’t need.
Trusted Brands We Service in Redwood City
We stock pins, springs, and common cylinders for Schlage, Kwikset, and Medeco hardware, which covers most Redwood City doors. That means fast turnaround on standard rekeys without waiting on parts. We also service Abloy high-security locks for commercial properties along Broadway, and we’re trained on the restricted keyways those systems use. Whether it’s a 1950s Kwikset knob on a Stambaugh Heller home or a new Schlage smart deadbolt on a condo near downtown, we work on what’s actually in your door, and we carry the brand-specific pins to do it right.
Common Rekey Locks Problems We See in Redwood City Homes
- Old tenant keys still floating around. A rental on Edgewood Road changes hands, but nobody can say how many key copies exist. Rekeying every exterior cylinder retires the old keys permanently, and we hand the owner a fresh set with a written key count.
- Flipper-special “rekeys” that weren’t. Builders and flippers swap in cheap non-bump-resistant pin and tumbler sets and hand over a “rekeyed” home. If the old keys were never truly retired, the lock is only cosmetically changed. We inspect and re-pin properly so the old key is dead.
- Strike plate problems disguised as lock problems. In older downtown bungalows near Broadway and Middlefield, doors settle and strike plates drift. The lock cylinder is fine; the alignment is the culprit. We check both and only charge for the actual fix.
- Brand mismatches on the same door. A Kwikset knob paired with a Schlage deadbolt means the two can’t share one key without a cylinder swap. We’ll quote the swap on the phone so there’s no surprise on site.

FAQs About Rekey Locks in Redwood City
We quote a real, itemized price on the phone before anyone is dispatched. You’ll know the per-cylinder rate, the key-blank cost if it’s a restricted brand, and the total before we put a tech on the road. That number is the number on your invoice. No $19 teaser, no arrival-time upsell. If the lock type changes the math, we tell you before we leave the phone call. Call (409) 405-4485 for a free estimate.
For three standard Schlage or Kwikset doors, expect 45 to 60 minutes on site. A single deadbolt is about 15 to 20 minutes. Older mortise locks in downtown bungalows can add time because the cylinder has to be removed and re-pinned carefully. We give you a realistic window on the phone, and with The Relay Visibility Guarantee you can track our tech’s live arrival time on your phone.
Not without a cylinder swap. Kwikset and Schlage use different keyways, so one key cannot operate both without changing one of the cylinders to match the other brand. A cylinder swap runs $20 – $35 per door, and we’ll tell you that on the phone before scheduling. Once swapped, both locks share a single key. Call (409) 405-4485 and we’ll quote the exact swap for your door.
You received a live trackable arrival link before they left, showing the technician’s location in real time. You got a written price before dispatch. And when they arrive, the tech is in a Preston uniform, background-checked, and carrying identification that matches the name you were given at booking. Before-and-after photos of the work get sent straight to your phone under The Relay Visibility Guarantee. You’ll never wonder who’s at your door in Redwood City.
If the hardware is functional and you just need to retire old keys, rekeying is almost always the better value at $25 – $45 per cylinder versus replacing a entire lockset. Replace when the lock is physically worn, the finish is failing, or you want a smart lock upgrade. We’ll assess your hardware and give you a straight answer. The 365-Day Done Right Promise covers rekeys, and the written guarantee on every repair includes a free second visit if anything fails.
