Rekeying is the locksmith service Montalvin homeowners need most often, and this unincorporated pocket of West Contra Costa County has its own reasons for that. Most homes here went up between the 1940s and 1970s, and decades of key copies, roommate changes, and handyman fixes have left a lot of properties with mismatched keys on original single-cylinder deadbolts. Add the damp marine air rolling in off San Pablo Bay, and the exterior hardware on these older homes seizes and corrodes faster than you’d see inland. Cypress Lock & Key has served Montalvin since 2017, and we work on the lock you already have rather than pushing a full replacement. Call (877) 265-4385 for a straight answer on your rekey or any lock issue.
Why Montalvin Homes Are Different
Montalvin is an unincorporated pocket of West Contra Costa County where most homes are older single-family houses on raised foundations. For a locksmith, that means the job often isn’t just the front door. These properties have gate locks, garage hasps, and sliding patio door locks that get just as much daily use as the main deadbolt, and they’re exposed to weather in ways indoor hardware never is. The marine-layer fog off San Pablo Bay keeps exterior metal damp much of the year, and ground-level gate and shed locks seize from rust far sooner than front-door locks. We see original wood-framed doors with single-cylinder deadbolts from the 1950s and 1960s that still work fine mechanically but haven’t been rekeyed in decades.
The high water table and bay-adjacent dampness change how hardware ages in Montalvin. Keys that would turn smoothly in an El Sobrante lock might grind or stick here because the internal pins have corroded. Many properties still have old mismatched keys from years of DIY rekeys and partial replacements, which is a security problem as much as a convenience one: you don’t know who holds a working copy. That’s why rekeying is the service we recommend most often in this area. It’s faster than replacing hardware, it works on the locks you already have, and it gives you a clean key map in one visit.
Styles & brands we work with







Our Main Montalvin Services
Two services account for most of the calls we answer from Montalvin: car key replacement and emergency lockouts. Each has its own page on this site where you can read the full detail, but here’s the short version of how each plays out locally.
Car Key Replacement in Montalvin
Losing a car key in Montalvin usually gets discovered in a driveway, not a parking garage. With older homes on quiet residential streets, many residents park in carports or at the curb, and the damp air near San Pablo Bay adds a wrinkle: keys left outdoors or in a jacket by the door are more likely to corrode at the fob contacts. We cut and program replacement keys for most makes on the spot, without sending you to a dealership across the county. For the full detail on what we cover and what it costs here, see Car Key Replacement in Montalvin.

Emergency Locksmith in Montalvin
Getting locked out in Montalvin is different from a dense city. Streets here are residential, distances to the nearest commercial strip are longer, and when the fog rolls in, standing outside a locked house at night gets cold fast. Our emergency service is built for exactly that: a call, a confirmation of your address in 94806, and a technician heading your way to get you back inside without damaging the door or the lock. Homeowners with original wood-framed doors need careful entry methods, not a crowbar. The full emergency detail, including how fast we respond and what a late-night lockout costs, is on Emergency Locksmith in Montalvin.

Rekey Locks in Montalvin
Rekeying in Montalvin usually means resetting decades-old hardware so that one key controls the doors you actually use. The housing stock here, mostly mid-century single-family homes, often still runs on original Schlage or Kwikset cylinders with worn pins and mismatched keys from past roommates, tenants, or handymen. The damp air off San Pablo Bay accelerates internal wear, and we regularly see cylinders in Montalvin that need a pin-and-spring refresh before a clean rekey can hold. For property owners and landlords, rekeying between tenants is the fastest way to restore control without replacing every lock. You can read the full scope of our rekey work on the Rekey Locks page.
Lock Rekey
Signs you need it
You have a key that works in the front door but not the back, or you can’t account for every copy of your current key.
What it costs in Montalvin
A basic lock rekey in Montalvin typically runs $20 to $35 per cylinder, with the door handle and deadbolt on the same door usually priced together.
How we do it
We pull the cylinder, replace the internal pins to match a new key, reassemble the lock, and test it in the door so the old key no longer turns.
Rekey Door Lock
Signs you need it
You’ve moved into a Montalvin home, ended a relationship, or had work done by someone who may have kept a copy of your key.
What it costs in Montalvin
Rekeying a door lock in Montalvin costs $20 to $35 per cylinder, and if you’re doing multiple doors in one visit the per-door labor drops since we’re already on site.
How we do it
We rekey the cylinder to a new key, then, if you ask, key the additional doors alike so one key operates every lock you choose.
Keyed Alike
Signs you need it
Your key ring has three or four different keys for one house and you’ve stopped remembering which one opens what.
What it costs in Montalvin
Keying locks alike in Montalvin runs $20 to $35 per cylinder, often with a lower effective cost when we rekey four or more locks in one appointment.
How we do it
We set each cylinder to the same key cut, so one key turns every deadbolt, knob, and entry lock you approve, without replacing any hardware.

What Montalvin Customers Say
"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"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
— Allen Chen"Commercial job, panic bar and a master key system for a small office. Clean install and clear documentation of which key opens what."
— Sofia Hernandez
