Chino Hills, San Bernardino County
Need a New Key but Not a New Lock in Chino Hills?
Short answer: To change the key without replacing the lock, you rekey it: the cylinder is re-pinned for a new key and the old one no longer turns it. If the cylinder is worn, corroded or the wrong keyway, swapping just the cylinder is the next step. In Chino Hills, we look at your lock first, tell you which route fits, and give a firm quote.

Something prompted this search: a lost key ring, a roommate who moved out with a copy, a contractor who still has your garage key, a tenant who left on bad terms, or a house you just bought. In every case the goal is the same: make the old key useless, keep the lock. You don't need new hardware for that, and it rarely takes more than one visit. In Chino Hills, Julian's Locksmith can usually re-pin your existing locks the same day we first see them. We verify that you live there or own the place, quote the work in advance, and hand you new keys before we pack up.
What to expect in Chino Hills
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 Chino Hills. 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.
What we can do on-site
- Deadbolts: new key, same bolt. Deadbolts take the most abuse, since they lock every night. If yours turns smoothly but the key's history worries you, a rekey fixes the real problem. If it's stiff or the throw is short, we check alignment with the strike plate first, because re-pinning can't cure a door that has shifted.
- Door knobs and levers with keyed entry. Some knobs release their cylinder only after the whole knob comes off; others have a small access hole. We identify which you have, work carefully around the finish, and test the latch when we're done. If the knob is loose or the spindle is worn, we say so, because no rekey will fix that.
- 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.
- Patio doors, security gates and screen doors. Hookbolt and mortise-style locks on patio and security doors can often be rekeyed in place, though some are riveted into the frame and need replacing. We identify the model first and tell you what's feasible before we begin, so there are no surprises midway through the visit.
- An honest rekey-or-replace check. Before touching a cylinder, we try the lock: turn the key, throw the bolt, feel for grit, check the strike plate alignment and look for cracks. That short check tells us whether a rekey will last. If it won't, we show you what's wrong and price both options.
How Chino Hills shapes the job
High-end homes in Chino Hills often carry expensive locks: heavy handlesets, custom finishes, multipoint systems. Rekeying them preserves the investment. We re-pin the cylinders, or swap to restricted high-security cylinders where the body is compatible, so your key control improves while the beautiful hardware stays on the door and the finish stays unmarked. We also keep a written record of the cylinders and keyways, so future additions to the property match.
Inland heat bakes locks. Brass expands, lubricants dry out, and plastic parts in some budget locks warp. Rekeying a sound lock is fine, but a heat-damaged one may deserve a cylinder swap or replacement. We check the plug, test the latch and use dry lubricant, because oil collects dust and bakes into gum on hot afternoons in Chino Hills. A short check each spring catches sticking before summer makes it worse.
Builder-grade locks in newer Chino Hills tracts are fully rekeyable, and a rekey soon after closing is smart, because construction crews and sales staff may have held copies. We re-pin the entry deadbolts and handlesets to a combination only you hold, keeping the finishes the builder installed and sparing you the cost of swapping hardware that works perfectly well. Rekeying a new house is a cheap way to start with a clean key history.
Example situations
- A shop owner in Chino Hills 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 property owner with a gated side yard discovers the padlock key was cut for a gardener who left long ago. The padlock itself is solid. We re-pin it, cut new keys and check the hasp, so the gate stays shut, the old gardener key is dead metal, and nothing has to be bought new.
- A landlord with a rental off Grand 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 resident of Chino Hills 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.
How the visit works
- Describe the lock and why the key needs to change. Photos help more than descriptions. Snap the front of each lock, the edge of the door where the latch sits, and any stamp on the cylinder. We can often recognize the lock, say whether it's re-pinnable and quote the visit before we arrive.
- Show that you're allowed to change it. If you live in a rental, tell us up front. Landlords control the locks in most leases, so we need their permission, and sometimes the landlord will want to book us directly. Protective-order lock changes follow their own rules, which we're glad to explain.
- 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.
- Remove the cylinder and re-pin it. We unscrew or release the cylinder, use a plug follower to push the plug out without losing the springs, and swap the key pins for ones that fit the new key. Each cylinder is measured twice. Then it goes back into the lock and the hardware is refitted.
- Test the new key and the working door. Testing includes the lock's feel. A stiff turn, a gritty plug or a bolt that stops short means something else is wrong, and we fix it or tell you. Smart locks get their backup key tested as well as their keypad.
- 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
- How many keyed cylinders you're changing. Count carefully before you call: storm doors, patio doors, gate locks, the shed padlock. The cylinder you forget to mention is the one that keeps an old key alive. We'd rather quote a complete job than leave a gap in your security.
- Rekey, cylinder swap or full replacement. Rekeying usually costs less than replacing, but not always. A cheap, worn lock can cost almost as much to rekey as to swap for a new one, and the new one lasts longer. We'll tell you where the break-even sits for your particular hardware.
- 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.
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 Chino Hills.
What not to do
- Expecting a rekey to make a weak lock strong. Re-pinning changes who can use the lock, not how well it resists force. A flimsy deadbolt or a short strike screw is still flimsy afterward. For better protection, add a quality deadbolt, a longer strike screw and a reinforced frame.
- Rekeying a lock that is already failing. If the bolt is cracked, the plug is corroded or the latch sticks, new pins won't help. You pay for the rekey and then for a replacement. Have the lock inspected first so the money goes into the right fix.
- Waiting for the next lost key. A key that has gone missing doesn't announce where it is. The sooner you rekey, the sooner a stranger's copy becomes useless. Putting it off for months leaves your doors on a combination someone else may hold.
Advice before you book
- Photograph the lock before you call. Get the keyhole side, the edge of the door where the latch sits and any name stamped on the cylinder face. Those three photos let us recognize the lock, tell you whether it can be rekeyed and quote the visit before we arrive.
- Treat a rekey as a mini tune-up. While the lock is apart, tighten the mounting screws, check the strike plate, clean the latch and add a dry lubricant. A smooth lock is also less likely to jam when you're in a hurry with a handful of groceries.
- 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.
- Renting? Ask in writing. Most leases make the landlord responsible for locks, and some forbid changes. Get permission by email or text and keep it. California law sets specific duties for landlords on deadbolts and protective-order lock changes, so the conversation is worth having.

Frequently asked questions
Will the lock look different or need new holes drilled?
No. When we change the key, the lock stays on the door exactly as it is: same handle, finish, bore and screw holes. Nothing needs drilling or filling. The only visible change is a new key. If we swap a cylinder, the face may differ slightly in finish, and we match it as closely as the maker's parts allow.
Do I need to be home while you change the key?
We need someone present at the start to verify ID and proof of residence or ownership, show us the locks and approve the quote. After that, you can step away while we work, though most people stay to watch. For a rental or business, an authorized manager can sign off. New keys go to a verified person only.
Can you change just one lock instead of the whole house?
Yes. If only one door is a problem, we change that one. Just remember that the new key won't match the others unless we pin them alike. Many people change the key on one lock after a loss, then decide to match the rest so they carry a single key. We lay out the options and price each one.
Can you really change the key without replacing the lock?
Yes, for most keyed locks. We remove the cylinder, replace the pins inside it to match a new key and put it back. The deadbolt, handle, finish and strike stay on your door, and the old key stops working. The exceptions are damaged, corroded or unusual locks, which may need a cylinder swap or replacement. We check yours on site in Chino Hills and tell you which applies.
Can I change the key myself?
Sometimes. Kwikset SmartKey locks reset with a small learn tool and a working key, which most owners manage. Conventional locks need a plug follower, replacement pins and a key gauge, and the springs fly if the plug comes out wrong. A DIY kit suits a patient person with matching hardware. If you'd rather not risk a lock that won't turn, call us.
What actually changes inside the lock?
Only the pins in the cylinder. Each chamber holds a key pin, a driver pin and a spring. We swap the key pins for sizes that match your new key, which moves the shear line to a new position. The bolt, latch, springs and mounting parts stay the same. It's a small mechanical change, not a rebuild, and it's why a rekey often costs less than a new lock.
How far is Chino Hills from your base?
