Change Key Without Replacing Lock: Rekey Options in Fontana

What to expect in Fontana

It helps to keep a short checklist of what survives a key change. Stays: the lock body, bolt, latch, strike plate, handle or lever, finish, door prep and mounting screws, plus any keypad, touchscreen or Bluetooth electronics on a smart lock. Changes: the key pins inside the cylinder and the key itself. Does not change automatically: keypad codes, app guest access, garage remotes and whatever neighbors or relatives are holding for you, which is why we review those with you at the end of the visit in Fontana. The lock's strength also stays the same. Rekeying makes the old key useless but does not turn a weak lock into a strong one, so a budget deadbolt stays a budget deadbolt. If you want better security, we can swap in a higher-grade cylinder or deadbolt, and we'll price that separately so you can see the difference. A rekey is also a good moment to look over the door itself: strike plate screws, hinge screws and bolt throw all get a check before we pack up.

How we can help in Fontana

• Deadbolts: new key, same bolt. A single-cylinder deadbolt is the easiest lock to rekey. We release the cylinder from the bolt body, re-pin it to a new key and refit it in a few minutes. The bolt, backplate and finish never leave the door. You get new keys, and every old copy stops working.
• Mortise locks in older homes and storefronts. Original mortise hardware in older Fontana homes can be decades old and worth keeping. The cylinders come in standard sizes, so a new one can be fitted if the old one is worn out. We keep the escutcheon, the knob and the key's look, and change only what you need changed.
• Cylinder swaps when a rekey won't hold. Some cylinders are too worn, corroded or damaged to re-pin reliably. Rather than push a bad plug through another rekey, we fit a new cylinder of the same brand and keyway into your existing lock. You get a fresh mechanism and a new key, and the lock body, trim and finish stay on the door.
• Smart locks and keypads with a key override. Smart deadbolts usually keep a conventional key cylinder as a backup, and that cylinder can often be rekeyed independently of the electronics. We change the key and leave the keypad, app and wiring alone. Then we remind you that PIN codes are a separate matter.
• An honest rekey-or-replace check. Sometimes the right answer is neither. A door that has dropped or a misaligned strike plate makes a good lock feel bad, and a few screws and a re-chiseled mortise fix it. We'll tell you if the problem is the door rather than the lock.

How Fontana shapes the job

Family homes in Fontana accumulate keys: kids, sitters, neighbors, relatives. A rekey resets the lot. We keep the locks you chose and give you a fresh set, then help you decide who truly needs one. It is a sensible habit to rekey when a teenager's friend group changes, a nanny leaves or a child moves out. A single visit can cover the front door, back door, garage entry and side gate together.

Older Fontana homes often have hardware worth keeping: a heavy brass entry set, a mortise lock original to the door, glass knobs with a deadbolt added later. Replacing those means new bores, filled holes and a different look. Changing the key keeps the character. We rekey or swap the cylinder, keep the trim, and tell you plainly if the lock body is tired enough to retire.

HOA communities sometimes control exterior hardware: finish, style, even brand. Changing a key without replacing the lock keeps your door within the rules, since nothing visible changes. We rekey entry locks and private gates, leave common-area hardware alone, and suggest you check the architectural guidelines before swapping any visible lock for something new. Nothing about the exterior of your home changes, so there is nothing for the architectural committee to object to.

Situations this covers

• A landlord with a rental off Jurupa Avenue gets the unit back from a tenant who left on poor terms and kept one key. The Schlage deadbolts are in good shape, so we rekey both and keep the hardware. The landlord leaves with a short record for the next move-in, and the old key no longer fits.
• A shop owner in Fontana lets an employee go, and that employee kept a key to the back door. The storefront has a keyed mortise cylinder and an Adams Rite deadlatch. We rekey both cylinders, cut keys for the current staff and leave the door itself untouched, so the shop opens on schedule the next morning with no hardware to repaint.
• A renter who has just received a protective order asks her landlord for new locks. In certain protective order situations, California requires landlords to change them within 24 hours of a written request (Civil Code sections 1941.5 and 1941.6). The landlord books us, we confirm authority with the landlord, rekey the entry deadbolt, test the lock and hand the new keys to the landlord to give to her.
• A resident of Fontana loses a key ring at the gym. There's no address on it, but the house key is on there, and she doesn't want to replace a handleset she loves. We rekey the deadbolt and latch to a new key, cut three copies, and the lost ring becomes a set of metal charms with no door to open.

From your call to the finished job

1. Describe the lock and why the key needs to change. Count how many keyed locks you want changed and whether you still have a working key for each. A working key makes the job simpler, but it isn't required. Tell us about any smart locks, gates or padlocks so we plan time for them.
2. Show that you're allowed to change it. California's Locksmith Act, administered by the Bureau of Security and Investigative Services, is why licensed locksmiths ask these questions. Our license is LCO7891, and you can look it up at search.dca.ca.gov. The check takes a minute and protects you as much as us.
3. Inspect the lock and choose rekey, cylinder swap or replace. We test the lock before touching it: key action, bolt throw, latch retraction, strike alignment. A sound lock gets a rekey. A worn or corroded cylinder gets a swap. A cracked or failing lock gets a replacement quote. You see the options and choose.
4. Remove the cylinder and re-pin it. Where a cylinder can't be re-pinned, we fit a new one in the same keyway, or a different one if that's your goal. Interchangeable cores are swapped with a control key in seconds, and padlocks are opened at the work tray.
5. Test the new key and the working door. We test the new key in each lock, in both directions, with the door open and then closed. We try the old key to confirm it no longer turns. Then we make sure the bolt throws fully into the strike and the latch catches smoothly.
6. Hand over keys and check what's left. The last step is a question: who else needs a key? Family, a neighbor, a pet sitter? We cut them now so nobody has to be guessed at later. Then you approve the work, we settle up as quoted and leave the door as we found it, only with a new key.

How we quote the job

• Brand, keyway and security level. Pin counts matter too. Five-pin cylinders are the norm; six-pin cylinders and sidebar designs take more care and sometimes special blanks. We identify the cylinder type from a photo when we can, so the quote matches what we find at the door.
• How many new keys and what type. Keys are cut on site, and each one adds a small amount to the job. Most households want three to five. Restricted or six-pin keys need special blanks and cost more, but copies can't be made at a kiosk, which helps if you've had trouble with stray duplicates.
• Timing, travel and add-on work. Planned visits are easy to schedule. If your key has just been stolen and you need the lock changed soon, tell us at the start so we can give you an honest arrival estimate and bring the likely parts. We quote before any work begins.

Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in Fontana.

What not to do

• Assuming a new key cancels keypad codes, app guests or remotes. The key and the electronics are separate systems. Changing one leaves the other open. After a rekey, review every PIN, app invite and garage remote, and remove anyone who shouldn't have access.
• Buying a DIY rekey kit for the wrong brand. Kits are built for specific keyways, and a Kwikset kit won't help a Schlage lock. Pins that look similar can sit at the wrong depth. Check the brand and keyway before you order, or let a locksmith handle it.
• Rekeying a rental without permission. A tenant who changes locks without the landlord's consent can break the lease and block emergency access. Ask in writing first. Landlords have their own obligations too, including working deadbolts on main entry doors under Civil Code section 1941.3.

Advice before you book

• Keep the brand and model if you have the box or receipt. A model number lets us check whether parts and cylinders are available, which matters for older or decorative locks. Take a photo of the paperwork and file it with your home records.
• Don't let copies pile up. A key you can copy at a kiosk for a few coins will be copied. If you want control, ask about restricted keys. Even if you don't, keep a count and ask anyone you hand a key to for it back later.
• Use a puff of graphite or PTFE spray in the keyway once a year, never household oil. Oil traps dust and bakes into gum in a hot, dry climate, while a dry lubricant keeps the new pins moving and the key turning without effort.
• Decide who really needs a key before we arrive. Every key you add is another way in. Four to six works for most households. Write the names down and keep the list somewhere safe, so you know who to ask when the next lost key turns up.

Getting to Fontana

Fontana is about 16 miles from our San Bernardino base, roughly 22 minutes in light traffic via Palm Avenue to I-215 South. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

Once the evening commute thins out on Foothill Boulevard, drive times usually shrink. That makes an evening call before closing a practical option for non-urgent jobs that you couldn't fit into the workday.

About Fontana: Bono's Historic Orange, an orange-shaped fruit stand built in 1936, still stands on Foothill Boulevard, the old Route 66 through Fontana.
