Pomona Lock Rekey: New Keys Pinned Into Your Existing Cylinders

How this works in Pomona

Rekeying is the right call far more often than people expect, but it isn't universal. Standard pin-tumbler hardware from Kwikset, Schlage, Weiser, Yale, Baldwin, Sargent and Corbin Russwin re-pins easily. Kwikset SmartKey cylinders use a sidebar and sliders instead of loose pins, so they reset with a tool and a working key rather than a pin kit. Interchangeable cores are swapped with a control key after we pin a new core. High-security cylinders with patented keyways, like Medeco, Mul-T-Lock or ASSA, can be rekeyed, but key blanks and some parts are controlled by authorized dealers, so registration paperwork matters. Then there are locks that shouldn't be rekeyed at all. A cylinder with wallowed-out pin chambers, broken springs or a cracked cam won't hold new pinning reliably. Some inexpensive imported keypad locks use proprietary cylinders with no pin kits available. A lock that was forced during a break-in usually needs replacement, not new pins. When someone in Pomona calls, we ask about brand, age and symptoms so we arrive prepared, and we tell you at the door if a cylinder isn't worth the labor.

Work included on a typical visit

• Kwikset SmartKey resets. If you've lost the only working SmartKey, the tool method is off the table. We can decode or disassemble the cylinder, or fit a replacement cylinder keyed to your other doors. We also confirm the SmartKey keyway matches your standard Kwikset hardware so a single key really does run every lock in the house.
• 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 Pomona site are fast.
• Keying locks to a key you already carry. Have a key you like? If the keyway matches, we can pin your other cylinders to it so one key runs the house. We decode that key first, and if its cuts are worn we correct them to factory depth, so future copies work in every lock rather than just the one you started with.
• Key decoding and code cutting. A traced copy repeats every flaw of the original: rounded peaks, shallow cuts and burrs. Decoding reveals the intended depths, which we write down so replacement keys for your Pomona home or business can be cut accurately later, even if every physical key is lost at once.
• Rekeying locks with no working key. When nobody has a key, the cylinder still comes out; it just takes another route. We pick the plug to the open position, or work a thin shim between plug and shell, then follow it out and re-pin as usual. Ownership documents matter even more here, because a no-key rekey is also, functionally, an opening.

How Pomona shapes the job

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.

Apartment rekeys are about turnover speed and key control. Many complexes run a master system so maintenance can enter every unit, which means each unit's cylinder carries master pins. We re-pin unit cylinders to new change keys while keeping the master working, or swap interchangeable cores where the property uses them. Tenants need landlord authorization for a rekey, and California law gives tenants with protective orders specific lock-change rights.

Student rentals change occupants constantly, and keys get copied freely between roommates. For landlords renting near Fairplex, rekeying between leases or after a roommate leaves is the practical way to know how many keys exist. We re-pin front, back and garage-entry cylinders quickly, cut one key per tenant plus owner copies, and can install restricted-keyway cylinders if casual copying at hardware stores keeps happening.

Common situations

At a townhome in Phillips Ranch, a woman asks for her two Schlage deadbolts and a Kwikset knob to be rekeyed after a roommate moved out. The Schlage cylinders come apart on the kitchen counter, where we sort the old pins, fit new ones cut for a fresh key and reassemble. The Kwikset SmartKey needs only a learn tool and a minute or two. Every lock then works on the new key, the roommate's copy opens nothing, and she keeps the hardware she already paid for.

• A typical call: a dental office near Adobe de Palomares lets a front-desk employee go, and the key never comes back. The suite has a storefront door with a mortise cylinder, a rear exit device with a rim cylinder and three interior office locks. We re-pin all five after the last patient leaves, stamp each new key with an identifier, and hand the office manager a written list of keys issued.
• As an example, an owner rents a guest casita behind the main house in North Pomona and has just replaced the cleaning crew. Changing the keypad codes takes a minute, but the old crew also had the override key. We re-pin that deadbolt cylinder to a new owner key, rekey the casita's sliding door handle to match, and log the single copy issued to the new cleaners on the key sheet.
• Picture a small private school whose doors run on small format interchangeable cores, and the facilities lead retires without handing over the control key. Without it, no core can be swapped. We pick one core to the control line, decode the control bitting from its pins and cut a new control key. The school then decides whether to re-core every door to a fresh control system.

From your call to the finished job

1. Count cylinders and confirm authorization. Before we arrive, we ask how many keyed cylinders you have, the brands, and whether any are master keyed or high-security. At the door we confirm photo ID and proof that you live at or own the property, or written authorization from the owner or manager.
2. Choose the new bitting. This is also when you decide on structure. Should the garage-entry and front door share a key? Does the pool gate or a casita get its own? We sketch the plan with you, assign a bitting to each group and confirm keyways so the plan is buildable before parts come out.
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. Pins are chosen by number from the bitting, not by eye. Once they're loaded, a fingernail or flat edge drawn across the plug tells the story: a pin standing proud or sitting low is the wrong size. If you asked for security drivers, they go into the shell at this stage.
5. Reassemble and test on the door. The plug goes back in behind the follower, the retaining clip or cam is reinstalled, and the cylinder is tried on the bench with the new key and the old one. Then it returns to the door, where we test it locked, unlocked and with the door closed against the strike.
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

• Brand and cylinder type. Less common hardware adds time for a reason. We may need a manufacturer-specific cylinder retainer, a different pin kit or a cam we don't usually stock. Decorative handlesets and imported European profile cylinders fall into that group. When we know the brand ahead of time, we bring the right parts and keep the job to one trip.
• Cylinder condition. Dust, heat and age wear cylinders down. Corroded springs, worn chambers or a cracked cam can mean extra parts or a replacement cylinder for one door. We point these out before doing the work, so a worn lock never turns into a surprise on the invoice.
• Access and missing keys. A ring of unlabeled keys is better than nothing, though sorting it takes some time. We try each key in each lock to find which still operate, and even a worn key that turns only with jiggling may be enough to get the cylinder out cleanly. Bring every key you have, including the ones you think are useless.

What to do before we arrive

• If your keys were stolen with something showing your address, such as a wallet with a license or a car with the registration in the glove box, treat the rekey as urgent. Call early in the day, and until we arrive, keep the deadbolt thrown and switch the garage opener to its lock or vacation mode.
• Include the door between the garage and the house. People remember the front door and forget that one, even though anyone holding an old key and a garage remote can walk straight in. Reset the opener codes on the same day.
• Rekey from a code, not from your oldest key. Ask your locksmith to decode the key and pin the lock to factory depths. A lock pinned to a worn key will feel fine with that key and stiff with every fresh copy someone cuts for you later.
• Check the keyway before planning one key for everything. Look at the brand stamped on each lock face or on your keys. Kwikset and Schlage keyways are different shapes, so mixing brands means either carrying two keys or replacing a cylinder or lock.

Mistakes to avoid

• Pulling the plug without a follower. The moment the plug leaves the housing, the springs shove drivers into the empty space, and the cylinder has to be reloaded pin by pin with tweezers, often after a spring or two has already vanished under the fridge.
• 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.
