Rekeying is the locksmith job we handle most often in San Lorenzo, and it almost always comes down to securing a mid-century home after a sale, a rental turnover, or a change in who holds the keys. Because most of the housing stock here went up between the 1950s and 1970s, we spend our days working on original knob locksets and builder-grade cylindrical deadbolts that share the same wear patterns across thousands of tract homes. If you need a rekey, a new key, or a lock that actually turns smoothly again, call Cypress Lock & Key at (877) 265-4385.
Why San Lorenzo Homes Are Different
San Lorenzo is an unincorporated, master-planned mid-century suburb, and that shapes nearly every lock we touch. The housing stock is overwhelmingly single-story ranch and tract homes built in a tight postwar window, which means the original hardware tends to be mortise/knob locksets and basic cylindrical deadbolts rather than modern smart locks or high-security systems. We see the same Schlage and Kwikset originals on block after block, and that repetition actually works in a homeowner’s favor: we know exactly how these locks age, what fails first, and which keyways they use without a long diagnostic session.
The East Bay climate adds its own layer. San Lorenzo gets mild, rainless summers and damp winters, so the common complaints are sticking deadbolts, corroded strike plates, and sun-bleached exterior finishes. Frost heave and frozen cylinders are not the problem here; moisture and decades of seasonal expansion are. Wood door slabs from that era also swell and shift, which means a rekey often pairs with a strike plate adjustment or a latch realignment so the new key turns cleanly. There is no real downtown commercial district to speak of, so the work is driven by resale churn and rental turnover along the 94580 corridors rather than storefront security. That has made Cypress Lock & Key familiar with the exact lock generations installed in San Lorenzo’s original build-out, and with what a 60-year-old door needs to keep working.
Styles & brands we work with







Our Main San Lorenzo Services
Most calls we take from San Lorenzo homeowners fall into two buckets: keys for vehicles and emergencies that cannot wait, which is why these two services have their own dedicated pages with full pricing and sub-job detail.
Car Key Replacement in San Lorenzo
When a car key snaps in the ignition or a transponder key stops reading, San Lorenzo residents usually face a choice between towing to a dealership and calling a locksmith with the right programming equipment. We handle automotive key replacement on-site, covering cut keys, transponder programming, and key fob work without sending you across the bay to a dealer service bay. The ranch-style driveways and attached garages here make driveway service straightforward, and we carry the key blanks and programmers for most domestic and import vehicles. For the full breakdown on car key replacement, see Car Key Replacement in San Lorenzo.

Emergency Locksmith in San Lorenzo
A lockout at 2 a.m. on a quiet San Lorenzo street is exactly the kind of call our emergency line handles. We have worked the 94580 neighborhoods enough to know that the original door hardware on these tract homes has a habit of letting the latch close behind you, and that the side garage door is often the one left locked with keys still inside. We arrive with non-destructive entry tools and rekey capability on board, so one visit can get you back inside and change the keys if needed. For response details and what to expect, see Emergency Locksmith in San Lorenzo.

Rekey Locks in San Lorenzo
Rekeying in San Lorenzo usually means one of two scenarios: you just bought or rented a mid-century ranch and want to know that no previous tenant or contractor still holds a working key, or you have a lock that has been weathered by decades of East Bay damp winters and no longer turns without a fight. The dense concentration of identical post-war tract floor plans means we often rekey one home and then hear from two neighbors on the same street who want the same builder-grade hardware secured. For a deeper look at the service itself, see Rekey Locks.
Lock Rekey
Signs you need it
You have lost a key, moved into a home in San Lorenzo, or ended a relationship where someone else had access to the house.
What it costs in San Lorenzo
Lock rekeying in San Lorenzo typically runs $75 to $135 for the first lock and $30 to $50 per additional lock on the same visit, depending on the cylinder type and whether we need to cut multiple keys.
How we do it
We remove the cylinder, swap the internal pins to match a new key, test the turn in the door, and hand you the new keys while the old ones stop working immediately.
Rekey Door Lock
Signs you need it
You want every exterior door in your San Lorenzo home to work from a single key, or a specific door’s key has been copied so many times you are unsure who holds one.
What it costs in San Lorenzo
Rekeying a door lock here ranges from $75 to $135 for the first cylinder, with additional doors typically $30 to $50 each when we are already on site.
How we do it
We pull each cylinder from its door, repin it to the new key code, reinstall it, and confirm that the latch and deadbolt both throw cleanly before we leave.
Keyed Alike
Signs you need it
You carry a different key for the front door, back door, and garage side door, and you want one key to open all of them.
What it costs in San Lorenzo
Keying multiple locks alike in San Lorenzo is priced per cylinder, so plan on $75 to $135 for the first and $30 to $50 for each additional lock brought onto the same key.
How we do it
We repin each cylinder to a single key code on-site so every designated door opens with one key, and we test each lock twice before handing over the set.
What Rekey Locks Costs in San Lorenzo
| Item | Typical range in San Lorenzo |
|---|---|
| First lock rekeyed | $75 – $135 |
| Each additional lock (same visit) | $30 – $50 |
| Keyed alike (per cylinder) | $75 – $135 first, $30 – $50 each additional |
These ranges cover the common Schlage and Kwikset cylinders we see in San Lorenzo. If a lock is badly corroded from damp winters or the door slab has shifted enough to bind the latch, we will tell you on the phone before anyone is dispatched so the price we quote is the price on the invoice.
How much does it cost to rekey a house in San Lorenzo?
Rekeying a typical San Lorenzo ranch with three exterior locks costs roughly $135 to $235 total, since the first cylinder runs $75 to $135 and each extra is $30 to $50. Call (877) 265-4385 for an exact figure before we schedule.
Is the rekey price quoted on the phone the final price?
Yes. We give you a firm quote on the phone before dispatching a technician, and that is the amount on your invoice. We do not add a call-out surcharge when the technician arrives, and if a lock needs replacement rather than rekeying, we tell you before doing the work.
Brands We Service in San Lorenzo
We work on the lock you already have, and in San Lorenzo that usually means original Schlage and Kwikset hardware. We also service Yale, Baldwin, Mul-T-Lock, and Sargent cylinders, and we stock common pins, key blanks, and tailpieces for those lines in our van so most rekeys happen in one visit. See our brands for the full list we carry and service.

What pushes a San Lorenzo job toward the higher end is usually the age of the door: swollen wood slabs from damp winters and 60-year-old mortise locksets can require extra latch alignment or strike plate work. The price we quote on the phone is the price on the invoice, and we tell you the full cost before anyone is dispatched.

No. Rekeying a lock is a hardware change, not a structural or construction job, so no city permit or HOA sign-off is required in San Lorenzo. The process takes under an hour for most homes and does not alter the door or its finish. We can rekey existing hardware without removing the door or changing its appearance.
Because San Lorenzo is compact and we are based nearby, residential lockouts are typically reached quickly once you call and confirm your address.

What San Lorenzo Customers Say
"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth a review."
— Sarah Vaughn"Got me back in and the price was fair for the hour. He did arrive closer to 45 minutes than the 20 he estimated, which felt long standing outside, but he was honest that traffic was the problem."
— Marcus Prince"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
— Lisa Sullivan
