Rekeying locks is the service Hillsborough homeowners call us for most often, and the reason is simple: in a town of gated estates and staffed households, keys change hands constantly. Housekeepers, contractors, nannies, and property managers all hold copies, and when a relationship ends or a remodel wraps up, the lock still opens for the old key. Citadel Locksmith has served Hillsborough since 2011, and we’ve rekeyed everything from mid-century ranches on Tobin Clark Drive to newer multimillion-dollar rebuilds behind private gates. Call (833) 589-8078 for a free estimate on rekeying your Hillsborough home.
Why Hillsborough Homes Are Different
Hillsborough is not a typical Peninsula suburb. The town’s zoning keeps density low, which means most of our work here happens on acre-plus lots with long private drives, not storefronts or apartment buildings. The housing stock skews toward large architect-designed estates, many built in the 1950s and 1960s, with a growing share of newer custom rebuilds. That matters for locksmith work because these homes rarely have builder-grade hardware. We’re far more likely to encounter multi-point door systems on solid mahogany entry doors, Baldwin or Sargent handlesets in oil-rubbed bronze, and gate operators that control access to the whole property.
The climate shapes the work too. Hillsborough’s dry, mild summers mean locks rarely freeze or corrode the way they do in colder climates. But seasonal rain and the coastal fog that rolls over the hills from late fall through spring cause wooden garden gates and older door frames to swell. When a gate swells, the latch misaligns and the deadbolt drags. We get a steady run of late-fall calls to lubricate and realign hardware before the wet season fully sets in. And because so many Hillsborough properties sit behind driveway gates on winding lanes, we often coordinate access with estate staff or a gate code before we ever reach the front door. Discreet, unmarked vehicles and pre-scheduled appointments are the standard here, not the exception.
Styles & brands we work with
Our Main Hillsborough Services
The two services Hillsborough residents call about most, beyond rekeying, are car key replacement and emergency lockouts. Both are covered by Citadel Locksmith, and both have their own dedicated Hillsborough pages with full detail.
Car Key Replacement in Hillsborough
Losing a car key on a property with a gated driveway creates a compounding problem: you can’t move the car, and in some configurations, the gate remote is in the car. We cut and program replacement keys for most makes and models, including transponder and fob-style keys, without sending you to a dealership. Hillsborough’s garages are often detached or set back from the street, so we come to you and handle the job on-site. Car Key Replacement in Hillsborough walks through pricing, timing, and what to expect when we arrive.
Emergency Locksmith in Hillsborough
Hillsborough’s quiet, private lanes make a nighttime lockout feel more isolated than it would in a denser town. If you’re locked out of your home or car, we respond with the same discreet, professional approach we use for scheduled work, no marked van announcing your situation to the neighborhood. Because many Hillsborough properties have secondary gates or separate garage access, our emergency calls here sometimes require patient problem-solving rather than a quick drill-and-replace. Emergency Locksmith in Hillsborough explains response times, what information to have ready, and how we handle gates and access codes during after-hours calls.

Rekey Locks in Hillsborough
Rekeying a Hillsborough home usually means rekeying more than a front door. Most properties have a main entrance, a service door, a garage entry, and sometimes a driveway gate, and a proper rekey makes every one of those openings respond to the same new key while the old key stops working entirely. When a housekeeper or contractor leaves your employment in Hillsborough, you may not know how many copies of your key exist. Rekeying removes that uncertainty in a single visit. Our full breakdown is at Rekey Locks, and below we cover the jobs we handle most often in Hillsborough, plus honest local pricing.
Lock Rekey
Signs you need it
If a key you gave out to a contractor, housekeeper, or guest still works your lock and you’re not certain who holds copies, it’s time to rekey.
What it costs in Hillsborough
A standard single-cylinder deadbolt rekey in Hillsborough typically runs $79 to $129, with 10 to 15 minutes per lock once we’re at the door.
How we do it
We remove the lock cylinder, swap the internal pins to match a new key, and reinstall the cylinder so the old key no longer turns it.
Rekey Door Lock
Signs you need it
After purchasing a Hillsborough home, you have no way of knowing which previous owners, agents, or staff still hold working keys, and a rekey should happen before you move anything in.
What it costs in Hillsborough
Rekeying all exterior door locks on a typical Hillsborough home with three to five openings generally falls between $169 and $289 total.
How we do it
We rekey every exterior door cylinder to a single new key, test each lock, and confirm the old key no longer works at any entry point.
Keyed Alike
Signs you need it
If you’re carrying three separate keys for your front door, service door, and gate and want one key to work them all, keyed alike is the fix.
What it costs in Hillsborough
Keying multiple locks alike is typically included in a whole-home rekey and runs from $169 to $289 for the full set depending on lock count.
How we do it
We repin each cylinder so all designated locks share one key, preserving the security of every entry while simplifying your keyring.

| Standard single-cylinder deadbolt rekey | $79 – $129 per lock |

| Keyed alike (all exterior locks to one key) | $169 – $289 total |
How long does rekeying take in Hillsborough?
Most Hillsborough homes are fully rekeyed in 45 to 90 minutes from driveway to test-lock, depending on lock count and gate access. We quote the full price before dispatch, and the number we give you on the phone is the number on the invoice. Call (833) 589-8078 for a specific estimate.
Can you rekey my Hillsborough home the same day?
Yes. Rekeying is a scheduled, same-day job in Hillsborough when you call by early afternoon, and we work around estate staff or gate access without disrupting your household. Call (833) 589-8078 to schedule, and we’ll confirm the total price before we head out.

That means no second trip for a high-security Medeco or Abloy rekey on an estate gate or a custom entry door. Most common rekey jobs are completed in a single visit. See our brands for the full lineup.

What Hillsborough Customers Say
"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."
— Greg Lawson"Told me over the phone that what I needed was a five dollar part from the hardware store, not a locksmith. I called him back a month later for real work because of that."
— Yolanda Mendoza"Key snapped off in the deadbolt. He extracted it without damaging the cylinder, which I did not think was going to be possible."
— Oscar Reyes
