Fast, Reliable Rekey Locks Across Belmont
Rekeying a lock in Belmont typically runs $95 – $160 per cylinder for standard pin-and-tumbler hardware, and most jobs on a mid-century ranch take under an hour once we’re at the door. The price is agreed in writing before we dispatch, so what you’re quoted on the phone at (409) 405-4485 is what appears on the invoice. We know Belmont’s housing stock well: the 1950s and 1960s homes off Ralston Avenue, the Eichler neighborhoods near Carlmont, and the hillside streets above El Camino Real all share a common quirk – original locks that have outlived several owners and an unknown number of old keys.
That’s why a rekey here isn’t just swapping pins. It’s verifying cylinder wear, confirming keyway compatibility, and sometimes catching a mortise lock that newer subdivision homes never had. We’re a Rekey Locks team that actually knows what’s behind the faceplate on a 1962 Belmont original. Call us, and a live person answers – no voicemail, no callback queue.
Why Preston Locksmith & Security Is Belmont’s Preferred Rekey Locks Company
Belmont homeowners call us because we put the final price in writing before a background-checked, uniformed technician ever leaves the San Francisco Bay Area dispatch office. Kevin Yoon, who leads Preston Locksmith & Security, built the company in 2008 on a simple rule: no anonymous tech, no vague hourly rate, and no bill that swells after the work starts. That rule applies to every rekey in Belmont, whether it’s a single deadbolt near Twin Pines Park or a full keyed-alike project in the Hallmark neighborhood.
Our relay visibility guarantee means you get a live, trackable arrival time before the tech heads your way. You’ll know who’s coming, what they look like, and exactly when they’ll be on your doorstep. That matters on Belmont’s winding hillside streets, where a four-hour window is not an answer. We’ve rekeyed doors on Old County Road, in the Sterling Downs area, and up near the Belmont Country Club, and the feedback from Belmont customers is consistent: the agreed price holds, the old keys stop working, and the guarantee is stamped on paper. Every job also comes with the 365-Day Done Right Promise – if it’s not done right, we make it right, with a free second visit if the repair fails.
Rekey Service in Belmont
Rekey Service in Belmont means swapping the internal pins inside your existing lock cylinder so the old keys no longer turn it, no new hardware needed. Because much of Belmont’s housing stock is mid-century ranches and Eichlers with original mortise and 1960s pin-and-tumbler locks, a rekey here often means servicing worn lock cylinders that newer subdivisions replaced decades ago. That makes old-key control and cylinder wear – not new-hardware sales – the real job on many Belmont doors.
A standard rekey on a Schlage or Kwikset deadbolt in Belmont runs $95 – $160 per cylinder, written price confirmed before we start. If the cylinder is too worn for the new pins to hold reliably, we’ll tell you at the door and quote a replacement before touching anything. No surprise fees after the fact.
Post-Move Rekeys
Belmont sees steady turnover in its older neighborhoods, and the first thing a new owner should do on a 1960s ranch or Eichler is kill every prior key. We don’t know how many copies were made over the decades, and neither do you. A full rekey of front, back, and garage doors brings that unknown back to zero. The old keys stop working right there. The price per cylinder is the same flat range, written down before we dispatch.
Lost Key Response
If a key went missing between Carlmont and El Camino, don’t wait to see if it turns up. We can be at a Belmont address fast, rekey the affected lock, and if you want, cut every lock on the property to a single new key at the same visit. We stock pins and parts for Schlage, Kwikset, Baldwin, and Yale hardware on the truck, so there’s no second trip for common cylinders.
Keyed Alike in Belmont
Keyed Alike in Belmont means rekeying multiple locks so one new key operates every door. That usually runs $95 – $160 per cylinder plus a small service fee for the visit, though a partially worn cylinder that’s too far gone will add the cost of a replacement at the same price we quoted before work started. On a mid-century home with original mixed hardware, the actual challenge is keyway compatibility – a 1960s Schlage keyway and a modern Kwikset keyway take different blanks, so we verify what’s in the door before promising one key works across all of it.
The 365-Day Done Right Promise covers every keyed-alike job in Belmont. If a cylinder we rekeyed doesn’t operate smoothly, we come back and make it right at no charge. That’s in writing on the invoice, not a verbal promise.
Front and Back Door Consistency
Most Belmont homes have three or four entry points: front, side, garage door into the house, maybe a back slider. If they’re on different keys, that’s four keys on a ring and a lot of fumbling in the dark. We can bring every pin-and-tumbler cylinder onto one key, and if there’s a mortise lock in the mix, we’re equipped to rekey that too. The price is per cylinder, agreed before we arrive.
Old Lock, New Key
On a rekey call off Ralston Avenue near the Belmont hills, our tech found a 1950s ranch with original Schlage pin-and-tumbler deadbolts and two tired Kwikset knobs where the owners had no idea how many prior keys existed. We pulled each lock cylinder, swapped the pins so the old keys stopped working, and keyed everything alike on a single new key – no drilling, no new hardware. The homeowner watched the whole rekey at the door and paid the agreed price before we packed up.
Trusted Brands We Service in Belmont
Most Belmont rekey work lands on Schlage and Kwikset – that’s what the mid-century builders used – but we also service Baldwin, Yale, Medeco, and Mul-T-Lock hardware where homeowners have upgraded. We stock common pins, springs, and cylinder parts for Schlage and Kwikset on the truck, so a rekey on a standard Belmont deadbolt is almost always same-visit. For Medeco or high-security cylinders, we still give a written price before we dispatch and tell you upfront if parts need to be ordered. You’ll never get a vague “we’ll figure it out when we arrive” answer from us. The quote is specific, and it holds.
Common Rekey Locks Problems We See in Belmont Homes
- Worn cylinders that won’t hold a rekey. Belmont’s aging mid-century lock cylinders are often worn enough that a straight rekey won’t hold – the pins need inspection, not just replacement. We test the cylinder before and after pinning so you don’t end up with a lock that works for a week, then jams.
- Teaser pricing that balloons at the door. Homeowners comparing rekey quotes get burned by bait pricing that spikes once the tech sees a mortise lock or a stuck deadbolt. That’s why we state the per-cylinder price on the phone and confirm it in writing before anyone is dispatched. The price on the invoice is the price you approved.
- Mismatched brands on keyed-alike requests. Keyed-alike requests across mismatched old and new brands – Schlage, Kwikset, Baldwin – fail when the technician doesn’t verify keyway compatibility before quoting. We check keyways first, then quote, so you’re not told “one key for everything” only to be handed two keys at the end.
- Mortise locks that scare off less experienced techs. Many of the older Belmont homes near the train tracks and along the hills still have original mortise lock bodies. A tech who’s never opened one will push a full replacement. We rekey mortise cylinders in place when the body is sound, and we tell you honestly if the plate needs a rebuild instead.
Pricing for Rekey Locks in Belmont, CA
A standard rekey in Belmont runs $95 – $160 per cylinder for common Schlage, Kwikset, Yale, or Baldwin pin-and-tumbler locks. The visit itself adds a service call that covers travel to your Belmont home and the first cylinder. If a cylinder is too worn to rekey reliably, we quote a replacement at that price before any work starts – not after. Mortise cylinder rekeys fall in the same range, though we inspect the body before pinning. High-security Medeco or Mul-T-Lock cylinders can run higher because the pins are proprietary, and we’ll give you that number on the phone. There is no call-out surcharge added on arrival, and the full price is quoted to you on the phone at (409) 405-4485 before anyone is dispatched. That’s the price that shows up on your invoice. No bait, no build-up.

FAQs About Rekey Locks in Belmont
We rekey old mortise and 1960s pin-and-tumbler deadbolts in place as long as the cylinder body is sound. Many of Belmont’s original Schlage and Kwikset cylinders were built better than what’s sold today, and they rekey fine after 60 years. If the cylinder is too worn to hold pins, we tell you at the door and quote a replacement before touching anything. We don’t push hardware. We fix what’s there. Call (409) 405-4485 and we’ll confirm what’s on your door before we arrive.
You get a written quote on the phone, itemized by cylinder, before we send anyone out. The tech arrives with that number on the work order, and the invoice matches it. No call-out surcharge added on arrival, no “labor fee” that appears after the fact. The price you approve is the price you pay. If something hidden changes the scope, we stop and requote in writing before proceeding. Call (409) 405-4485 for a free estimate now.
Plan on 25 – 40 minutes for the first door and about 10 – 15 minutes per additional cylinder on a standard Belmont ranch. If we’re keying three doors alike, expect the whole job to finish within an hour of arrival. Mortise locks add a few minutes each because the cylinder comes out differently. We’ll give you a time estimate on the phone along with the price, and you can track our arrival live. Call (409) 405-4485 to schedule.

Most Belmont homes with original Schlage and Kwikset hardware key alike with no problem – we rekey each cylinder to the same new pin pattern and cut matching keys.

That’s the Relay Visibility Guarantee, and it’s standard on every Belmont visit. Call (409) 405-4485 and we’ll walk you through exactly what happens before we ever ring your bell.
