Rekey locks is the call we make most often in Alamo, and it rarely looks like a single front door. Homes in the 94507 zip sit on half-acre-plus lots with detached garages, guest quarters, pool equipment enclosures, and driveway gates – sometimes five or six exterior locks per property. When a homeowner here changes cleaning crews, ends a contractor relationship, or moves into an estate property, key control matters more than convenience. Citadel Locksmith has served Alamo since 2011. Call (833) 589-8078 for a locksmith who stocks the hardware Alamo homes actually use.
Why Alamo Homes Are Different
Alamo locksmith work skews heavily toward estate and perimeter security because the housing stock demands it. Most homes were built between the 1970s and 2000s as custom or semi-custom builds, which means door prep and hardware vary house to house. There is no single builder-grade template. A Schlage deadbolt on one door, a Baldwin entry set on another, and an older Kwikset knob on the side garage entrance is common on the same property.
The Diablo Valley climate shapes the work too. Hot, dry summers bake exterior hardware. Dust from long private driveways works its way into cylinders and gate operators. Then winter rains arrive and seize anything that was already marginal. We regularly rekey locks in Alamo where the cylinder still functions but the finish is pitted and the tailpiece is starting to bind. On hillside and canyon-edge lots near the oak edges of the valley, the nearest neighbor can be a quarter mile away, which is exactly why working gate locks and reliable deadbolts get treated as priority items, not afterthoughts.
Styles & brands we work with
Our Main Alamo Services
Most Alamo homeowners first call us for one of two reasons: a car key that stopped working or a lock emergency that cannot wait until morning. Both are available now.
Car Key Replacement in Alamo
Long driveways and detached garages mean car keys in Alamo get lost in odd places: garden beds, garage cabinets, the bottom of a pool bag. When a transponder key or key fob fails, dealership pricing and wait times make it worse. Citadel Locksmith programs replacement keys and fobs at your Alamo property, same day in most cases. We work with the major automotive key platforms and carry programming equipment in our service vehicles. Car Key Replacement in Alamo covers what we replace, what it costs, and how long it takes.
Emergency Locksmith in Alamo
A failed deadbolt on a gated driveway at 11 p.m. is not the same as an apartment lockout in Walnut Creek. There is no leasing office and no maintenance line. Citadel Locksmith responds to Alamo lockouts, break-in repairs, and lock failures outside standard hours. We arrive with a stocked van and the hardware to make the door secure before we leave. Emergency Locksmith in Alamo explains response coverage, what we can do on the spot, and what to expect for after-hours service.

Rekey Locks in Alamo
Rekeying in Alamo usually means resetting every exterior lock on the property to a single new key, not just swapping one cylinder. Between the main residence, detached garage, and driveway gate, a typical Alamo rekey covers three to five locks. The goal is simple: one key operates everything, and every old key stops working immediately. This is the fastest way to reclaim control after a move, a tenant change, or a lost key, and it costs far less than replacing functioning hardware. We handle full-property rekeys as a standard part of our Rekey Locks work, including the gate hardware many locksmiths will not touch.
Lock Rekey
Signs you need it
A key has gone missing, a contractor or cleaner still holds a copy, or you have moved into a new Alamo home and do not know who has keys.
What it costs in Alamo
Expect $18 to $35 per cylinder for standard residential locks, plus a service call.
How we do it
We disassemble each lock, replace the internal pins to match a new key, reassemble, and verify the old key no longer turns.
Rekey Door Lock
Signs you need it
One specific door is on a different key than the rest of the house, or a single lock fails after a key is lost.
What it costs in Alamo
A single door lock rekey runs $18 to $35 if we are already on site for other work; a standalone trip adds a service call.
How we do it
We remove the cylinder, repin it to the new key, test operation through multiple cycles, and reinstall with the tailpiece properly aligned.
Keyed Alike
Signs you need it
You carry separate keys for the front door, side door, garage, and gate, and want one key for all of them.
What it costs in Alamo
Keying multiple locks alike is $18 to $35 per cylinder, assuming the locks share a compatible keyway.
How we do it
We pin each lock to the same key cuts, confirm all cylinders turn smoothly, and test the key at every door, including the gate.
What Rekey Locks Costs in Alamo
| Item | Typical range in Alamo |
|---|---|
| Per-cylinder rekey (standard residential) | $18 – $35 |
| Service call | $45 – $100 |
| Whole-home rekey (3-5 locks, most Alamo homes) | $99 – $275 |
Most Alamo rekeys run between $150 and $300 all in, depending on cylinder count and whether gate hardware is included. Price goes up when locks are high-security brands like Medeco or Mul-T-Lock, since those require specialized pins and more labor per cylinder. We quote the full price on the phone before anyone is dispatched, and that is the price on the invoice.
How long does a rekey take at an Alamo home?
A standard three-to-five lock rekey takes 45 to 90 minutes on site. High-security cylinders or gate hardware can add 30 minutes.
Will the old keys really stop working after a rekey?
Yes. Rekeying replaces the internal pins, so every previously issued key is dead immediately. We test this in front of you before leaving.
Brands We Service in Alamo
We are trained and equipped for Schlage, Kwikset, Medeco, and Abloy hardware, plus the premium architectural lines that show up on Alamo estate homes. Parts for common Schlage and Kwikset cylinders ride in the van. We stock our brands across the full spectrum, and most rekeys and cylinder swaps are done same day from van inventory.

Prices in Alamo run slightly higher than in neighboring Danville or Walnut Creek because properties are larger and we are often servicing four or more locks on a single visit. High-security brands like Medeco and Abloy cost more due to parts and labor. You will get the full price on the phone before we dispatch, and we do not add a call-out surcharge when the tech arrives.

What Alamo 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."
— Brandon Wong"Installed a smart lock and actually set up the app and the codes with me instead of leaving me to figure it out from a leaflet."
— David Nguyen"Something came loose about a month after the work. Called them, and they were back out the next day and fixed it at no charge. Didn't argue, didn't try to bill me for the trip."
