Rekeying locks is the service Alamo homeowners call us for most often, and the reasons are tied directly to how this town is built. Most of the homes here sit on multi-acre lots behind long private driveways, with detached garages, guest houses, and pool structures that each carry separate locks and gate hardware. A move-in rekey in Alamo rarely means two or three locks. It usually means six or eight, spread across a gate, a garage door, an interior door, and the main residence. If you need a locksmith in Alamo who can handle that scope without making you book a second appointment, call Cypress Lock & Key at (877) 265-4385.
Why Alamo Homes Are Different
Alamo is a semi-rural enclave in the San Ramon Valley where custom and semi-custom single-family estates dominate the housing stock. Most were built between the 1970s and the 2000s, and nearly all of them sit on acreage with detached structures. A typical rekey call here is not one front door. It’s a driveway gate, a detached garage side door, a pool house latch, and sometimes an interior door between the main wing and a guest suite. Each of those has its own key, its own wear pattern, and its own story.
The climate does real work on that hardware. San Ramon Valley summers run hot and dry, with Diablo winds that pull moisture out of wooden gates and exterior door frames. That warping throws latch alignment off, so a gate that worked fine in May will not catch by August. Winter rains reverse the problem, swelling the same wood until old exterior locks seize or bind. Cypress Lock & Key has served Alamo since 2017, and we have learned to plan for those seasonal shifts. When we rekey a property here, we check the strike alignment and the gate frame while we are changing the pins, because in Alamo the mechanical issue and the lock issue are usually connected.
The other thing that defines Alamo work is the clientele. These are homeowners and estate managers who want discreet, appointment-based service, not a truck idling in the driveway while someone figures out a price. They tend to ask for better hardware than builder-grade, which is why we stock Baldwin and Sargent cylinders on the truck and rekey Medeco and Mul-T-Lock systems on site when the job calls for it.
Styles & brands we work with







Our Main Alamo Services
Two services generate the majority of our calls from Alamo: car key replacement and emergency lockout response. Both require equipment and training that most general locksmiths do not carry, and both are covered in depth on their own pages.
Car Key Replacement in Alamo
When you live on a multi-acre lot in Alamo, losing a car key is a different kind of problem than it is in a dense suburb. There is no walking to a corner store, no neighbor two doors down. Your car is likely in your own driveway, but it might as well be ten miles away. We come to the property, cut and program a replacement key on the spot, and handle transponder and chip keys for most major makes. That means you do not have to tow the vehicle to a dealership in Walnut Creek and arrange a ride home. Full detail is on the Car Key Replacement in Alamo page.

Emergency Locksmith in Alamo
A lockout in Alamo often happens at the gate, not the front door. Someone closes a driveway gate behind them without a key, or an older electric strike fails with the family locked outside the perimeter. We take those calls seriously because around here, being locked out can mean standing at the end of your own driveway in the dark. Our emergency service covers gate lockouts, home lockouts, and garage access failures, with the same up-front pricing we use for scheduled work. The details are on the Emergency Locksmith in Alamo page.

Rekey Locks in Alamo
Rekeying in Alamo means changing the internal pins of each lock so old keys stop working and a new key takes over. For homes here, that usually spans multiple structures: the main house, a detached garage, a gate, and occasionally a pool house or guest suite. We do this without removing or replacing the existing hardware, which preserves the finish on older Baldwin or Yale sets that are often original to homes built in the 1990s and 2000s. More detail is on our Rekey Locks service page.
Lock Rekey
Signs you need it
You have moved into a home in Alamo and cannot confirm how many previous owners, contractors, housekeepers, or caretakers still hold a working key.
What it costs in Alamo
A standard single-cylinder rekey in Alamo runs $65 – $150 per cylinder depending on the brand and finish, with most homes needing five to eight cylinders total.
How we do it
We label each lock, disassemble the cylinder, swap the old pins for a new configuration, reassemble, test the new key, and hand you all copies while verifying the old ones no longer turn.
Rekey Door Lock
Signs you need it
One door in the house works on a different key than the others, or a recent housekeeper, contractor, or tenant change means someone outside the home still has a key.
What it costs in Alamo
Rekeying a single door lock in Alamo typically costs $65 – $150, and we can match it to your existing house key so your keychain stays to one or two keys.
How we do it
We remove the cylinder, inspect the springs and pins for wear (the valley’s summer heat dries out original lubricant), switch the pins, and test the lock on the door before we leave.
Keyed Alike
Signs you need it
Your Alamo property has four or five different keys for the house, garage, gate, and pool house, and you cannot remember which key goes to which door.
What it costs in Alamo
Keying multiple cylinders alike in Alamo costs $20 – $40 per cylinder for the rekey labor, plus $5 – $20 per key blank, so a six-lock job typically starts around $150 and climbs with hardware condition.
How we do it
We repin every cylinder you want on one key so a single key opens the front door, the side gate, the garage man door, and the guest entrance.
What Rekey Locks Costs in Alamo
| Item | Typical range in Alamo |
|---|---|
| Standard rekey per cylinder | $20 – $40 |
| Full rekey (first lock, incl. service call) | $65 – $150 |
| Key copies per blank | $5 – $20 |
How much should a rekey cost in Alamo?
A full home rekey in Alamo usually lands between $250 and $600, depending on how many detached structures and gates share the key. That includes the service call, labor, and new keys, with no hidden add-on at the door. We quote the whole job on the phone before dispatch at (877) 265-4385.
Can you rekey the gate and house on the same key?
Yes. We regularly key Alamo driveway gates, detached garages, and main-house doors to a single key. The job takes longer when the gate uses a padlock or an integrated electric striker, but both can be matched. Call (877) 265-4385 and we will tell you if your gate hardware can be key-combined.
Brands We Service in Alamo
We work on the lock you already have, rather than pushing a replacement. That matters in Alamo, where Baldwin and Yale hardware is common on higher-end homes, and where estate-style gates often carry Sargent or Mul-T-Lock cylinders. We stock pins, springs, and blanks for those lines on the truck, so most rekeys happen in one visit. See our brands for the full list of eight lines we service.
Pricing for Locksmith in Alamo, CA
| Service | Typical range in Alamo |
|---|---|
| Standard rekey per cylinder | $20 – $40 |
| Full rekey (first lock, incl. service call) | $65 – $150 |
| Key copies per blank | $5 – $20 |
| Car key replacement (basic non-transponder) | $75 – $200 |
| Transponder key programming | $75 – $225 |
| Emergency lockout response | $75 – $250 |
| Gate latch repair or alignment | $95 – $250 |
| High-security rekey (Medeco, Mul-T-Lock) | $30 – $60 per cylinder above standard |
What pushes a price up in Alamo is usually the gate. When a wooden driveway gate has warped in the summer heat, the lock cylinder may be fine but the strike needs realignment, and that is a second line item on the invoice. Older high-security hardware from Sargent or Medeco also costs more to rekey because the cylinders require proprietary pins and a longer labor window. Every price on this table is a real range, not a teaser. We quote the full number on the phone before anyone is dispatched, and that number is the number on your invoice.

FAQs About Locksmith in Alamo
No. Rekeying an existing lock is a maintenance task and does not require a building permit anywhere in Contra Costa County, including Alamo. Modifying a driveway gate that sits on an HOA-managed easement can trigger an architectural review, but simply changing the lock cylinder on an existing gate does not. If you are unsure, your HOA documents will say.
For emergency calls, our average response across the 94507 zone is under one hour during normal business periods, and we run after-hours dispatch as well. Long private driveways and unmarked lanes can slow the final approach, especially at night, so we ask for a gate code or a good landmark when you call.
Yes. Alamo is entirely unincorporated Contra Costa County, so there is no separate city limit to worry about. We cover all of 94507, including the hillside estates off Stone Valley Road and the ranch properties along the valley floor. The full area also reaches into the cities listed in the Service Area section above.
