Rekeying is the service Atherton homeowners call Citadel Locksmith about most, and the town’s housing stock shapes every job differently than it does in neighboring Menlo Park or Redwood City. Homes here sit on acre-plus lots behind long drives and automated gates, so the work skews toward programmed access control, multi-door master-key systems, and hardware that gets punished by damp winter fog under a heavy tree canopy. Call (833) 589-8078 when you need a locksmith in Atherton who works with the hardware serious about security, from Medeco and Abloy high-security cylinders to the Schlage and Kwikset locks on staff doors and pool houses.
Why Atherton Homes Are Different
Atherton is almost entirely large custom single-family homes, many built or rebuilt between the 1990s and 2010s. Those newer builds tend to carry multi-point European hardware, smart locks, and integrated security on every exterior door. The pre-war estates that remain have original solid-core doors and mortise locksets that need vintage parts, not the universal-fit replacements a van stocked for tract housing would carry. The town’s heavy tree canopy and damp winter fog keep exterior hardware and gate actuators wet for months at a time, which accelerates corrosion and seizing on exposed locks, keypads, and hinges, especially on shaded north-facing entries. That means a standard rekey here often involves working around oxidized cylinders and swollen wood, not just swapping pins. Atherton’s ZIP code 94027 covers the entire town, and the work concentrates on gated entries, service gates, and staff doors rather than the front-door hardware a locksmith sees in most Bay Area cities. Contractors and domestic staff arrive through side gates, and residents rarely use front doors, so the most common call is a worker or guest locked out at a motorized driveway gate whose keypad failed after a rainy season, not a house lockout.
Styles & brands we work with
Our Main Atherton Services
Atherton homeowners call us for two services more than any other: car key replacement for vehicles that sit in long driveways or garages, and emergency response for gate failures and staff-door lockouts that cannot wait for a scheduled appointment.
Car Key Replacement in Atherton
Replacing a car key in Atherton usually means a transponder or proximity fob for a late-model vehicle, and the cost of going through a dealership for that work is avoidable. We cut and program keys on site, including high-security blade styles, so you are not towing a vehicle or waiting on a parts counter. The long driveways here do not change the key work itself, but losing the only working fob to a car parked behind a gate you also cannot open is a compounding problem, and we can solve both in one visit. See Car Key Replacement in Atherton for details on what we cover and what it costs.
Emergency Locksmith in Atherton
Most emergency calls in Atherton involve a motorized driveway gate whose keypad has died, a staff door that will not open after a winter of moisture, or a lockout at a service entrance. Our emergency service covers lockouts, broken keys, and failed hardware on the spot, without sending you to a voicemail queue. The damp, shaded entries common in this town mean we arrive expecting corroded cylinders and seized actuators, so the truck is stocked for that reality.

Rekey Locks in Atherton
Rekeying a home in Atherton means changing the internal pins of each lock so old keys stop working, without replacing the hardware itself, and it is the fastest way to take back control of who holds a key after a contractor finishes, a caregiver leaves, or a set of keys goes missing. On newer estates, that often involves working through a house full of Schlage or Kwikset cylinders and a couple of high-security Medeco or Abloy locks on the main entries, keying everything to one set of keys where possible. Older homes present mortise locksets that need vintage cylinder pins, not the standard kit every van carries. For the full scope of what we rekey, see Rekey Locks.

You have moved into a home, dismissed a staff member, or cannot account for every copy of a key that was ever handed out.
What it costs in Atherton
Standard cylinder rekeying in Atherton runs $20 to $45 per lock, with most homes needing two to six cylinders done.
How we do it
We disassemble each cylinder, swap the pins to a new key code, reassemble, and test every lock against the new key.

Signs you need it
A single exterior door has an old lock that still works but uses a key you no longer trust.
What it costs in Atherton
Expect $20 to $45 per lock for a standard Schlage or Kwikset rekey, with high-security Medeco or Abloy cylinders adding parts costs specific to the keyway.
How we do it
We pull the lock, rekey the cylinder to the new key, lubricate the mechanism, and confirm the deadbolt throws cleanly.
Rekey Service
Signs you need it
You want every exterior door on one key, including the gate or pool house, but the locks are a mix of brands.

Full-house rekey service in Atherton typically runs $150 to $350, depending on the number of cylinders and whether high-security locks are in the mix.
How we do it
We survey each door, rekey all cylinders to a single key code where the hardware allows, and hand you a working key for every entry.
Keyed Alike
Signs you need it
Your front door, back door, and gate each take a different key, and you want one key for everything.

Keying locks alike costs $20 to $45 per cylinder for standard hardware; high-security and vintage mortise cylinders may run higher.
How we do it
We rekey each cylinder to the same key code, verify the key turns smoothly in every lock, and leave you with a single key ring.
What Rekey Locks Costs in Atherton
| Item | Typical range in Atherton |
|---|---|
| Rekey standard cylinder (per lock) | $20 – $45 |

Can you rekey a home in Atherton the same day you are called?
Yes. We keep rekey kits for Schlage, Kwikset, Medeco, and Abloy on the truck, so most Atherton homes are done the same day. Call (833) 589-8078 for a time window.
Will rekeying my Atherton house really stop every old key from working?
Yes, when each lock is rekeyed to a new code, every previously issued key becomes useless in that cylinder. The exception is a key that opens a lock we did not rekey, which is why we walk the whole property with you first.
