Fast, Reliable Rekey Locks Across Colma
Rekeying a lock in Colma typically costs $25 – $45 per cylinder for standard Kwikset or Schlage hardware, and most houses here are finished in under an hour. If you just moved into a home off El Camino Real, lost a key, or ended a lease with a tenant who never returned their copy, this is the fastest way to make every old key useless without replacing a single piece of hardware. We’re Preston Locksmith & Security, and our Rekey Locks team works throughout Colma with a written price confirmed before anyone is dispatched. Call (409) 405-4485 and you’ll get a live person, not a queue.
Why Preston Locksmith & Security Is Colma’s Preferred Rekey Locks Company
Colma is not like most Bay Area towns. The residential footprint is small and tightly clustered east of El Camino Real, with most of the rest of the town given over to cemeteries and auto dealerships. That means our Colma rekey calls are short routes, and we know the housing stock: tract homes from the 1950s through the 1970s with builder-grade Kwikset and Schlage cylinders that have been through decades of coastal fog. Kevin Yoon, who leads our team, has trained technicians on those exact cylinders. We do not send an anonymous subcontractor. A background-checked, uniformed tech arrives with a live trackable ETA, and the price was already settled in writing before they left.
Colma homeowners tell us the same thing again and again: another locksmith quoted one number on the phone, then a different one at the door. That is not how we work. The price we quote on the phone is the price on the invoice. No call-out surcharge added on arrival, no “per cylinder” surprise once the hardware is apart. The 365-Day Done Right Promise covers every rekey we do in Colma, and if a repair fails, the second visit is free.
Rekey Service in Colma
Rekey Service in Colma means swapping the internal pins and springs inside an existing lock cylinder so the old keys stop working, without replacing the hardware itself. For most Colma homes, that is the smarter play: the original Kwikset or Schlage lock housings are often in fine shape, and the only real problem is that someone out there has a key you do not control.
It costs $25 – $45 per cylinder for standard hardware. High-security brands like Medeco or Mul-T-Lock run higher because the key blanks and pins cost more, and we will quote that range before we touch the lock.
New keys, same locks
Most Colma homeowners choose to rekey instead of replace because the hardware still works. We disassemble the cylinder, clean out years of coastal grit, re-pin it to a fresh key code, and cut new keys on the spot. Every old key fails at the curb.
Rental turns and tenant changes
Property managers around Colma call us between tenants. A rekey is cheaper than swapping hardware and takes far less time. We can key all exterior doors to one new key and log the key codes so future rekeys are quicker.
Keyed Alike in Colma
Keyed Alike in Colma means every exterior door on your property works from a single key. If your front, back, and side doors each take a different key, we re-pin all three cylinders to match one key code. Most Colma homes have two or three exterior doors, and the job usually runs $75 – $135 for the set plus the key cuts.
This is especially popular right after a move-in. The previous owner handed over a jumble of keys, nobody knows what half of them open, and the garage side door still has a Kwikset that has not been turned in years. One visit. One key. Done.
Single-key convenience for the whole house
We re-pin each exterior cylinder to the same key cuts, cut as many keys as you need, and test every door before we leave. Schlage and Kwikset cylinders are the most common in Colma and they key alike without any issue.
Landlord and property manager keying plans
For Colma rental owners, we can key all units in a building to a master key while each tenant keeps their own individual unit key. That includes Medeco and Mul-T-Lock restricted keyways if you want to prevent tenants from copying keys at the hardware store.
Trusted Brands We Service in Colma
We work on the hardware Colma homes actually have: Kwikset and Schlage on nearly every tract house east of El Camino Real, plus Yale on older door sets and Baldwin on higher-end remodels. We also service Medeco and Mul-T-Lock restricted cylinders for commercial and multi-unit properties. Because the Colma housing stock is so consistent, we keep the common replacement pins, springs, and key blanks for these brands stocked, so a typical rekey does not wait on a parts run. High-security keyway work may take an extra day if we need to order restricted blanks.
Common Rekey Locks Problems We See in Colma Homes
- Builder-grade cylinders binding after decades of fog and grit. The original Kwikset and Schlage cylinders in Colma’s 1950s – 1970s tract homes collect coastal dampness and fine grit, and the pin stacks bind. An honest rekey includes cleaning and re-pinning the stack, not just cutting a new key and calling it done.
- A low phone quote that balloons at the door. A caller accepts a cheap rekey estimate, then the tech arrives and quotes a higher “per cylinder” price. We settle the number before anyone is dispatched, and that is the invoice price.
- Landlords asking for a “quick rekey” without specifying key control. If a cylinder was never actually re-pinned, a previous tenant’s key still works. We re-pin every cylinder and document the key code, so you know exactly what opens what.
- Deadbolts installed with short screws into trim, not framing. A family off El Camino Real had a back door deadbolt that looked fine until we pulled it. The strike was screwed into the trim. We reset it with long screws into the framing and swapped in a bump-resistant cylinder while the hardware was off.
Pricing for Rekey Locks in Colma, CA
A standard rekey in Colma runs $25 – $45 per cylinder for residential Kwikset or Schlage hardware. Keying multiple cylinders alike typically lands between $75 and $135 for the full set, including cut keys. High-security brands like Medeco and Mul-T-Lock run $45 – $90 per cylinder because the restricted blanks and specialized pinning cost more. Full hardware replacement, when needed, is a separate quote covering the parts and install. The price we confirm on the phone is the price on your invoice, and we do not add a call-out surcharge when the tech arrives. Call (409) 405-4485 for an exact quote before anyone is dispatched.

FAQs About Rekey Locks in Colma
Yes. We confirm the full rekey price on the phone before anyone is dispatched to your Colma address. The price covers the cylinder re-pinning, the new keys, and the labor. Nothing is added on arrival, and the figure you hear is the figure on the invoice. Call (409) 405-4485 and we will give you a dollar range for your specific hardware.
Most Colma homes only need a rekey. If the hardware still turns smoothly and the housing is intact, re-pinning the cylinder makes every old key useless for $25 – $45 per cylinder. Replacement only makes sense if the hardware is broken, badly corroded, or you want a different finish or security grade. We will tell you which one actually applies and quote both before doing anything.
For a two- or three-door house in Colma, a full rekey plus new keys usually takes 45 minutes to an hour on site. Keying all doors alike adds little time because we re-pin each cylinder in sequence. Your tech’s live ETA shows you exactly when they will arrive, and they send before-and-after photos as part of The Relay Visibility Guarantee.
Our technicians are background-checked and arrive in a Preston Locksmith & Security uniform. You get a live trackable arrival time, so you see who is coming and when. When the tech knocks, they will have the written price for your job already on record. If anything does not match, call (409) 405-4485 and we will verify it on the spot.
No. Drilling is a last resort. In the vast majority of Colma homes, we extract a broken key or free a jammed cylinder without damaging the lock. If the cylinder is already failed beyond repair, we will quote a replacement before doing anything and drill only if you approve it. The goal is to leave you with working, rekeyed hardware, not a pile of it.
