Lock Rekey Service in Fontana

Short answer: A lock rekey replaces the small key pins inside your existing cylinder so a new key works and every old copy stops working. In Fontana, we do it on-site: each cylinder comes out, gets re-pinned to a fresh bitting, goes back in and is tested on the door. Your knobs, levers and deadbolts stay put, and you get new keys before we leave.

Lock Rekey in Fontana, CA — Rekeying pins and a lock cylinder

Booking a lock rekey in Fontana is simple. You tell us how many doors and which brands, we give you a quote and an honest ETA, and a technician working under California license LCO7891 arrives with pins and blanks already on board. We confirm you live at or own the property, then work door by door, testing each cylinder with the new key before the trim goes back on. Old keys get tried too, so you can watch them fail. You keep your existing hardware and leave with new keys cut to factory depths rather than copied from a worn original.

Rekeying is mechanical work, and understanding it helps you judge a quote. Inside a standard pin-tumbler cylinder, stacks of spring-loaded pins cross the shear line. The right key lifts each stack to exactly that line so the plug can turn. To rekey, we remove the plug with a follower so the springs stay put, pull the old key pins and fit pins sized to the new key's cuts. Schlage cylinders step in increments of .015 inch and Kwikset in .023, so a key gauge and the correct pin kit matter. Mix them up and the lock binds. Master-keyed locks add a layer, with extra master pins between the key pin and driver. Kwikset's SmartKey works differently: it has no pins to change. A learn tool, the current key and the new key reset the sidebar in moments, which is quick but only works on a clean, smooth cylinder. Most pin-tumbler deadbolts and knobs can be rekeyed. Exceptions include sealed budget hardware without a removable plug, damaged cylinders, and old locks with worn pin chambers that won't hold a precise stack. In Fontana's dusty air, cleaning grit and graphite out of the chambers is part of the job. Anything we cannot rekey is replaced rather than left half-done.

What to know first in Fontana

The quality of a lock rekey shows up in the keys. A careless job copies whatever key is handy, including years of brass worn off its cuts, and pins the lock to that wear. Months later a fresh copy cut to factory depths feels stiff or refuses to turn. We decode keys with a depth gauge, correct them to the manufacturer's specifications and cut new keys by code so every future copy matches. Bitting choice matters too. Each brand publishes a maximum adjacent cut specification limiting how far neighboring cuts can differ; ignoring it produces keys that drag or snap. We also avoid weak combinations, such as every cut sitting at nearly the same depth. Master keyed cylinders add another layer. A master pin, a thin spacer between key pin and driver, creates a second break so both a change key and a master key operate the lock. For Fontana businesses and rental owners, we can match an existing keying chart, strip master pins to make a cylinder single-key, or set up a fresh hierarchy. Keys can be stamped with identifiers, and you get a written list of what was cut and for which doors.

What we can do on-site

  • Kwikset SmartKey resets. SmartKey cylinders don't use loose pins. With a working key inserted and turned a quarter turn, a learn tool releases the internal sliders so a new key can be taught. We handle routine resets, including cylinders that jammed partway through the process, and we tell you when a forced or damaged SmartKey should simply be replaced.
  • Commercial mortise and rim cylinders. Mortise cylinders come in lengths matched to door thickness and trim, with collars and blocking rings that control how far the face sticks out. When we re-pin one, it goes back with the same collar stack and a snug set screw. A cylinder that protrudes or spins in its threads invites a wrench attack, so we correct that before handing over keys.
  • Interchangeable core swaps. Schools, clinics and larger offices favor interchangeable cores because a lost key means swapping a core, not touching door hardware. We pin cores to your existing system or establish a new control key, and when you ask, we keep spare pre-pinned cores ready so future changes at your Fontana site are fast.
  • Key decoding and code cutting. Some keys carry clues: a stamped code on the bow, a key-set mark from a master system, or a card filed with the original paperwork. For the rest, we check each cut's depth and its spacing from the shoulder, because right depths at the wrong spacing still bind. You get a bitting in the manufacturer's numbering that any qualified cutter can use.
  • Padlocks, cam locks and gate cylinders. Many laminated and solid-body padlocks, file cabinet cam locks and keyed gate hardware can be re-pinned to match your door key or a separate utility key. Cheap wafer cam locks often cost less to replace than to rekey, and we'll tell you honestly which route makes sense for each one.

How Fontana shapes the job

Clinics and medical offices protect records rooms, medication storage and staff-only areas, so key control after staff turnover matters. We rekey mortise and cylindrical locks across a suite, re-pin interchangeable cores where a building uses them, and keep a master system working so managers can still reach every room. Medication cabinet cam locks can often be rekeyed or swapped to fit the system, and we schedule around patient hours whenever possible.

In a gated community, your front door may be only one of several keyed points: pedestrian gates, pool gates, mailbox compartments and clubhouse doors. Most of those belong to the HOA, and we only rekey them with the association's written authorization. For your own home, we arrange gate access with you ahead of time, rekey every exterior cylinder, and can match a side-gate padlock to your house key when the hardware allows it.

If you leave before sunrise and get home after dark, scheduling matters as much as the lock work. We start at 6:30 a.m. every day and work into the evening, so a lock rekey can happen before your commute or after it. If you can't be there, an adult you authorize can meet us with documentation, and the new keys go only to that person.

Situations this covers

A Coyote Canyon homeowner has a Kwikset SmartKey deadbolt on the front door and a standard Kwikset on the garage entry, all opened by the old builder keys. For the SmartKey, we put it into learn mode and reset it to a new key in moments. For the garage lock we remove the plug, re-pin it to match and cut three keys by code. Then we test both locks from outside and inside, and the builder-era keys no longer turn either one.

  • As an illustration, three students renting a house in the 92335 ZIP code change roommates mid-year. The landlord authorizes a rekey of the front deadbolt, the knob and the garage-entry door. We re-pin all three to a new key, cut one key per tenant plus a copy for the landlord, and note on the invoice how many keys exist so the next turnover starts with an accurate count.
  • An office tenant asks us to rekey a door fitted with a Medeco cylinder after a key holder leaves. The cylinder is on a restricted system registered through a dealer years ago. We explain that blanks for that keyway are controlled, help the property manager track down the registration card, and coordinate the re-pin and new keys through the proper channel instead of improvising.
  • Say a homeowner tries to reset a Kwikset SmartKey deadbolt with the tool, gets interrupted halfway, and now neither the old key nor the new one turns. That's a familiar SmartKey failure. We work the cylinder back into a known state, complete the reset with a properly cut key, then check the remaining SmartKey locks in the house so all of them end up sharing the same key.

From your call to the finished job

  1. Count cylinders and confirm authorization. A quick photo of each lock face and the brand name on your key bow speeds things up. On arrival, we match ID to the property: a deed or tax bill for owners, a lease plus landlord approval for tenants, a management agreement or work order for property managers.
  2. Choose the new bitting. The new combination is chosen deliberately: no near-flat cuts, no steep jumps between neighbors and no repeat of the old bitting. For master keyed doors, we calculate every master pin size from the keying chart before opening anything.
  3. Remove each cylinder. We work one door at a time, so a home or shop is never left with holes in several doors at once. Screws, retainers and cams go into a labeled tray for that opening, and the tailpiece orientation is noted before anything slides out, which removes guesswork at reassembly.
  4. Re-pin at the shear line. This is the heart of a lock rekey. Each pin stack gets a new bottom pin matched to the new cut depth, and master pins are added or removed as the chart calls for. We inspect chambers and springs while the plug is out and replace anything worn.
  5. Reassemble and test on the door. Our test is a checklist, not a quick turn. Every new key goes in and out of each cylinder, the bolt is thrown from outside and from the thumbturn, the key has to return to rest and pull out cleanly after locking and unlocking, and an old key gets a fair try.
  6. Cut keys and leave a record. We cut the number of keys you ask for on a code machine, deburr them and test each one. You get a note of the bitting code and which doors share it, which makes future copies, added locks or another rekey straightforward.

What affects the cost

  • How many cylinders. Most of the labor is per cylinder, so a condo with two keyed locks and a house with seven are different jobs. A front entry set usually counts as two cylinders, the knob or lever plus the deadbolt, and garage-entry, side and back doors each add more.
  • Master keying and keying charts. If your building already runs a master system, matching the existing chart is faster than designing a new one. Without a chart, we may need to decode existing keys and cylinders first, and larger hierarchies with sub-masters add calculation and testing time.
  • Number and type of keys. How many keys, and what kind, matters. Ten keys for a busy office cost more than two for a couple, and patented keyways can't be cut from generic blanks. Key identifiers and color-coded heads are available when they help you keep track of who carries what.

Common errors that cost time and money

  • Forgetting the digital side. Rekeying the override cylinder on a keypad or smart lock stops old keys, but an ex-roommate's PIN, a past guest code or a shared app login still opens the door. Delete old users and change the master code on the same day the cylinder gets re-pinned.
  • Rekeying only the front door. Old keys still open the garage-entry door, the side door or a keyed patio handle if those cylinders are left out, which defeats the purpose of the rekey. Walk every exterior door before scheduling and list each keyed cylinder.
  • Ignoring an old master key system. If a previous owner or manager master keyed the property, a rekey that leaves the master pins in place still lets the old master key work. Ask for the master pins to be removed or the system rebuilt.

Practical tips before you call

  • Write down how many keys exist after a rekey and who holds each one. Knowing the count is the whole point of rekeying. For a business in Fontana, a simple sign-out sheet keeps that number accurate through staff changes and promotions.
  • Store the bitting code somewhere safe, like a sealed envelope with your home documents. With that code, a locksmith can cut working keys even if every physical key is lost, without pulling a lock apart or decoding a cylinder first.
  • Use a dry lubricant. Graphite or a dry PTFE spray keeps pins moving freely. Wet oils attract dust and pollen, then thicken in warm weather and gum up the chambers, which is a common reason keys start sticking a year after a rekey.
  • Ask about security drivers. During a rekey, spool or serrated driver pins can often replace plain ones where the manufacturer's parts allow, making the cylinder noticeably harder to pick without changing how your key feels in the lock. It costs little extra while the plug is already out.

Frequently asked questions

How long does a rekey take?

A standard Kwikset or Schlage cylinder takes a few minutes once it's off the door; removing and reinstalling trim often takes longer than the re-pinning itself. A typical home with several exterior locks is handled in one visit. Master keyed systems, mortise locks and cylinders without a working key take longer, and we tell you that when we quote.

Can every lock be rekeyed?

No. Most pin-tumbler cylinders can, but some imported keypad locks use proprietary cylinders with no available pins, cheap wafer locks often cost less to replace, and cylinders with worn chambers, broken cams or break-in damage won't hold new pinning reliably. Restricted high-security cylinders can be rekeyed, but keys and parts may have to come through an authorized dealer.

Do you rekey storefront and commercial door locks in Fontana?

Yes. We re-pin mortise cylinders on offices, Adams Rite-style storefront deadlocks, rim cylinders on exit devices from brands like Von Duprin, and interchangeable cores. Each cylinder is reinstalled with the correct cam or tailpiece so the hardware operates properly, and new keys can be stamped for tracking. An owner or authorized manager approves the work before we begin.

Can a landlord rekey between tenants, and what about protective orders?

Landlords commonly rekey between tenancies so an outgoing tenant's copies stop working. Separately, under Civil Code §1941.5 and §1941.6, a landlord must change the locks within 24 hours of a tenant's written request in certain situations involving a protective order or similar documentation. Re-pinning the existing cylinders is often the quickest way to meet that request, with the landlord's authorization.

Is rekeying as secure as installing new locks?

Against old keys, yes. Once re-pinned, a cylinder simply won't turn with the previous key. Rekeying doesn't upgrade the lock's grade, strike, bolt length or pick resistance, though. If your hardware is flimsy or damaged, replacing it may make more sense, and we can add security driver pins to many cylinders during the rekey for better pick resistance.

Do you carry the parts, or will something need to be ordered?

Our van carries pin kits for the common residential and commercial keyways, springs, drivers, retainers and a wide range of key blanks, so most rekeys finish in one visit. Restricted high-security keys, uncommon decorative cylinders and some proprietary smart lock cylinders may need ordering. When your description points that way, we say so on the phone, so nothing surprises you at the door.

How far is Fontana from your base?

Fontana is about 16 miles from our San Bernardino base, roughly 22 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
