Rekey locks in Key is the service we perform most often, generally for homeowners who have just closed on a house or had a set of keys go missing. Most of the homes here were built in the same few decades, which means many doors still carry the original Schlage or Kwikset cylinders the builder installed. The dry heat and hard water in this part of Arizona do not only affect landscaping – they get inside lock cylinders too, and we account for that on every rekey. If you need a locksmith in Key, call (888) 455-7175 and we will quote the full job on the phone before anyone is dispatched.
Why Key Homes Are Different
Key sits in the high desert northeast of the Phoenix metro, and the environment shapes the lock work we do here. The combination of intense sun exposure, fine dust, and low humidity wears on lock hardware in predictable ways. Exterior cylinders accumulate grit that works its way into the pin chambers, making keys harder to turn and eventually causing them to stick or fail. Interior locks fare better but still dry out, especially in homes where evaporative coolers add moisture during the summer monsoon months and then leave everything bone dry in June.
Housing stock in Key is primarily single-family and overwhelmingly frame-and-stucco construction from the 1980s through the early 2000s, with some older ranch-style homes and a scattering of newer builds. Most front and back doors are steel or fiberglass with standard 2-1/8 inch bore holes, which means the rekey work is predictable for a technician who has done it hundreds of times but often reveals cheap builder-grade hardware that was never serviced. An HOA is common in the subdivisions, and while none we have encountered restrict rekeying or lock replacement, many require exterior hardware finishes to stay within certain tones, so if you want to swap visible hardware we can tell you which finishes will keep the board off your back. On the dirt roads and larger lots toward the northern edge of the community, dust is the constant enemy of exterior locks, and we recommend a heavier-bodied lubricant than we would in town.
Styles & brands we work with







Our Main Key Services
When a Key resident calls Thornton Lock & Key, the two situations we hear about most are a dead car key or fob with no spare, and a lockout that cannot wait until morning. Both are jobs we handle directly, in the field, without asking you to call a dealer or a different company.
Car Key Replacement in Key
A lost or dead car key in Key usually means a trip to a dealership in Scottsdale or Mesa unless you call us instead, and on a summer afternoon that is a drive nobody wants to make with a vehicle that will not start. We cut and program transponder keys and fob-style keys on-site for most makes, often at a lower price than the dealer quotes. The heat is part of the job here too: key fob batteries fail faster in 110-degree interiors, and worn ignition cylinders are common on vehicles that have spent years parked in full sun. For the full rundown, see our Car Key Replacement in Key page.

Emergency Locksmith in Key
Locked out at night in Key, with the nearest busy commercial strip a good drive away, feels a lot more isolated than the same problem in central Phoenix. Our emergency response covers home and vehicle lockouts across Key, and we will tell you honestly on the phone how long the drive will take before you commit to anything. Broken keys, failed deadbolts, and doors that will not latch are all situations we see out here, and we arrive with the tools to fix the problem without destroying your hardware. Details are on our Emergency Locksmith in Key page.

Rekey Locks in Key

Most rekey jobs in Key come from one of two moments: the week after a home sale closes, or the morning someone realizes a key ring has gone missing somewhere between the mailbox and the garage. The houses here, mostly built between the 1980s and 2010s, almost always have Schlage or Kwikset hardware that rekeys quickly and cleanly, but the desert dust that builds up in those cylinders means we lubricate and clean as part of the job, not as an add-on. Rekeying is the fastest way to restore real security after keys walk away without replacing every piece of hardware on the door. For a deeper look at the service across the broader area, see our Rekey Locks resource page.
Lock Rekey
Signs you need it
You have closed on a new house, lost a key, ended a tenancy, or have a key you gave to a contractor or cleaner that was never returned.
What it costs in Key
A standard single-cylinder deadbolt or knob rekey in Key typically runs $18 to $35 per cylinder, with most homes needing three to five cylinders done.
How we do it
We remove the cylinder, replace the internal pins to match a new key, lubricate it, and test the lock several times before we leave.
Rekey Door Lock
Signs you need it
Any exterior door that still opens with a key you no longer trust, or that has a keyway worn loose enough that any similar key jiggles the cylinder.
What it costs in Key
Rekeying a door lock in Key is $25 to $60 per cylinder for most residential hardware, with the upper end covering Baldwin and Yale pieces.
How we do it
We key each door to one matching key, confirm the latch and deadbolt align correctly, and recommend a single key for all exterior doors if yours are currently keyed differently.
Keyed Alike
Signs you need it
Your keyring holds three or four separate keys for one house and you would rather carry one.
What it costs in Key
A keyed-alike rekey in Key runs $18 to $40 per cylinder, plus $4 to $8 per duplicate key, depending on how many doors are involved.
How we do it
We repin each cylinder to the same key code, cut duplicate keys on the spot, and test every lock on the property before we hand them over.
What Rekey Locks Costs in Key
| Item | Typical range in Key |
|---|---|
| Rekey per cylinder (standard Schlage/Kwikset) | $18 – $35 |
| Rekey per cylinder (premium or decorative) | $25 – $60 |
| Duplicate keys | $4 – $8 each |
How long does a rekey take in Key?
Most full-home rekey jobs in Key take 30 to 60 minutes once we are on site. Larger homes with many doors or mixed hardware brands may run closer to 90 minutes. Call (888) 455-7175 for a time estimate on your specific doors.
Should I rekey or replace my locks after buying a home in Key?
Rekey, in almost every case. Rekeying gives you brand-new keys that void every copy the previous owner handed out, at a fraction of replacement cost. We only recommend replacement when the hardware itself is failing. Call (888) 455-7175 and we can tell you which route fits your doors.
Brands We Service in Key
We work on the lock you actually have, not the lock we would rather sell you. In Key that means a lot of Schlage and Kwikset on tract and custom homes alike, plus Yale and Baldwin on higher-end and decorative sets, and Medeco, Mul-T-Lock, Abloy, and Sargent when a homeowner or small business wants real high-security cylinders. Our van carries common parts and pins for all of them, so most jobs finish in one visit. See our brands for the full range of manufacturers we support.

What Key Customers Say
"Does good work. Card payment was a bit of a production, so have another option handy."
— Robert Kowalski"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."
— Henry Park"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."
— Christine Nguyen
