Rekey Locks is the service Cupertino homeowners call Citadel Locksmith for most often, and it usually costs between $95 and $180 to rekey a standard single-cylinder deadbolt and knob set in the 95014 and 95015 ZIP codes. The work here is shaped by the housing stock: thousands of mid-century single-family homes built from the 1950s through the 1990s, many with original hardware that has weathered decades of dry summers and wet winters. Whether you just closed on a house near Rancho Rinconada or you’re updating a 1960s east-side tract home after a tenant change, call (833) 589-8078 and we’ll give you a firm price before anyone is dispatched.
Why Cupertino Homes Are Different
Cupertino’s locksmith work is not generic. Most of 95014 is detached single-family housing, and a large share of it was built between the 1950s and the 1990s, especially in the east-side tracts and Rancho Rinconada. Those homes often still have their original wood-frame doors. After the first winter rains, doors that have lived through sixty or seventy seasonal cycles swell and settle. A lock that worked fine in August suddenly binds in January because the strike plate has drifted a quarter inch. That means a re-key here frequently turns into adjusting hinges and strike plates, not just swapping pins.
At the same time, Cupertino’s newer construction and remodels lean hard toward smart deadbolts and premium hardware. The homeowner base near Apple Park and across the east side expects electronic entry systems and pick-resistant cylinders, not builder-grade fare. Tech employees buy, remodel, and re-key at a steady clip, which means we see a constant stream of move-in re-keys, smart-lock retrofits, and master-key upgrades on high-end single-family residences. Sun exposure also does its work here: south-facing exterior hardware weathers and wears, and we regularly replace tired cylinders and trim on those doors while we’re rekeying.
Styles & brands we work with
Our Main Cupertino Services
Most Cupertino calls to Citadel Locksmith fall into one of two categories: a car key that needs replacing, or a lockout that needs a response right now. Both are covered below, and each has its own dedicated Cupertino page.
Car Key Replacement in Cupertino
Cupertino drivers lose keys in the usual ways: between the seats of a car parked at the Apple Park visitor center, dropped on a trail at Rancho San Antonio, or left in a gym bag that walked out of a driveway off De Anza Boulevard. When that happens, going to a dealership often means towing the car and paying hundreds more than necessary. We cut and program replacement keys, transponder keys, and fobs on-site for most makes, which keeps you out of the dealership line. See Car Key Replacement in Cupertino for the full breakdown.
Emergency Locksmith in Cupertino
A deadbolt that will not turn at 11 p.m. on a rainy night off Stevens Creek Boulevard is a security problem, not a scheduling problem. Our emergency response covers lockouts, broken keys, and locks that fail after a break-in attempt, and we carry the cylinders, pins, and hardware to fix the problem on the first trip. Cupertino’s older doors fail more often in winter when swollen frames jam the bolt, and that is exactly when a fast response matters most. See Emergency Locksmith in Cupertino for details on what an emergency call involves.

Rekey Locks in Cupertino
Rekey Locks is the fastest way to take back control of who holds a key, and in Cupertino it is almost a seasonal service. After a home purchase in Rancho Rinconada or a tenant change in an east-side rental, you cannot know how many copies of the old key are floating around. We rekey the existing locks without replacing the hardware, which costs less than new locksets and restores security the same day. The local twist in Cupertino is that older 1950s and 1960s doors often have settled or swollen frames, so a re-key here frequently includes adjusting the strike plate and hinges so the rekeyed cylinder actually turns smoothly. We handle the full range: traditional Schlage and Kwikset cylinders, high-security Medeco and Abloy systems, and everything between. Learn more about the process on our Rekey Locks service hub.
Lock Rekey
Signs you need it
You have a new key that does not match the lock, or you have lost track of how many copies of your current key exist.
What it costs in Cupertino
A standard single-cylinder deadbolt rekey in Cupertino typically runs $60 to $90 per lock, depending on the cylinder type.
How we do it
We remove the cylinder, replace the pins to match a new key, and reinstall it, often in under twenty minutes per lock.
Rekey Door Lock
Signs you need it
You are moving into a new home in Cupertino, ending a relationship, or a roommate or tenant has moved out with their key.
What it costs in Cupertino
Rekeying a door lock in Cupertino usually falls between $75 and $130 per entry when strike plate adjustment is included.
How we do it
We re-pin the cylinder to a new key, then check and correct the strike plate alignment so the deadbolt throws cleanly.
Keyed Alike
Signs you need it
You carry three or four keys for one house and want a single key that works every exterior door.
What it costs in Cupertino
Keying multiple locks alike in Cupertino starts around $60 per cylinder after the first lock, so a three-door setup typically lands between $120 and $200.
How we do it
We pin every cylinder to the same keyway and cut enough copies for the household, then test each door in sequence.
What Rekey Locks Costs in Cupertino
| Item | Typical range in Cupertino |
|---|---|
| Single-cylinder deadbolt rekey | $60 – $90 per lock |
| Rekey door lock with strike plate adjustment | $75 – $130 per entry |
| Keyed alike (per additional cylinder) | $60 – $80 per cylinder |
How long does rekeying take in Cupertino?
Most Cupertino rekey jobs take between twenty and forty minutes per door. Older east-side homes with swollen frames or drifted strike plates take longer because we adjust the hardware while we’re there, and we will tell you that on the phone before you commit.
Can you rekey a Medeco or Abloy lock in Cupertino?
Yes. We stock pins and key blanks for Medeco and Abloy high-security cylinders, along with Schlage and Kwikset. Not all locksmiths speak Medeco or Abloy. We do, and we rekey them to factory spec in Cupertino without sending the cylinder out.
Brands We Service in Cupertino
We work with the brands serious about security. That means Schlage and Kwikset for everyday residential hardware, and Medeco and Abloy for high-security, pick-resistant systems on Cupertino homes that demand more. We stock key blanks, pins, and common replacement parts locally, so most brand-specific work is completed in a single visit rather than a special order. See our brands for the full roster and what each one is best for.

What Cupertino Customers Say
"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"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
