Upland, San Bernardino County
Rekey Locks After Losing Keys in Upland
Short answer: How fast you act depends on what went missing with the keys. Keys stolen along with your ID, or taken from a car parked at your house, call for a same-day rekey. A lone key dropped at a trailhead can usually wait a day or two. We work in Upland every day, 6:30 a.m. to 11:30 p.m.

You've checked every pocket, the car seat and the bottom of the bag twice, and the keys still aren't turning up. Before calling anyone, retrace your steps and phone the last couple of places you stopped; lost keys get turned in more often than people expect. If they're still missing by the end of the day, it's time to decide whether to rekey locks after losing keys in Upland, and which ones. This page walks through that decision the way we'd talk it over at your door: what was on the ring, whether anything ties it to your address, and how fast to move. When you're ready, Julian's Locksmith comes to you, re-pins the locks those keys opened and cuts new ones before leaving.
How this works in Upland
Two situations look alike but play out differently at a Upland front door. If you still have one working key, rekeying is straightforward: we use it to turn and remove each cylinder, re-pin it and test it. If the lost ring was the only set, we have to get into each cylinder without a key, usually by picking the plug or decoding the lock, before re-pinning. That adds time per lock and is worth mentioning when you call. Brand matters too. A Kwikset SmartKey cylinder resets quickly with its tool, but only with a working key in hand; without one it can be stubborn, and replacing that cylinder is sometimes the more sensible quote. High-security cylinders such as Medeco or Mul-T-Lock use controlled key blanks, so rekeying them may need parts from an authorized source. Whatever the mix, we explain each option when you rekey locks after losing keys, and you approve the plan before work starts.
How we can help in Upland
- Rekeying only the locks the lost key fit. Before we touch anything, we map the house. Each lock gets tried with the keys you still have, and we decode any we can't match. The result is a short list of cylinders the lost key could open. Those get re-pinned; the rest stay as they are unless you decide to put everything on one new key.
- Rekeying when no key is left. When every key is gone, we first get you inside if needed, then work through the cylinders one at a time. Before any of that, we confirm you live there: ID with the address, a lease, a utility bill or closing papers. Then the locks get a new combination and you get a fresh, counted set of keys.
- Mailbox lock changes after a lost ring. Mail theft is a common follow-up to stolen keys, because your mailbox key was probably on the same ring. For cluster boxes, who changes the lock depends on ownership: the Post Office handles boxes it owns, while HOA or property-owned boxes are changed by the owner's locksmith. We'll help you work out which applies.
- Lost work keys and master key exposure. In a master keyed building, losing a key isn't a one-door problem. A change key affects its own lock; a master or grand master affects every cylinder beneath it. We review the keying chart, if one exists, before quoting, and we'll be honest when the better long-term fix is restructuring the system.
- Lost car keys on the same ring. When the car key went with the house keys, the vehicle becomes a second exposure, especially if the registration with your address was in the glove box. We can cut and program a replacement for many vehicles and, on many models, erase the lost key from the immobilizer so it can't start the car. Some makes need the dealer.
What's different about Upland
Long commutes leave the house empty for long stretches, and keys get lost far from home: on a train platform, at a park-and-ride, in an office tower an hour away. If the keys left with your car or a work badge showing your name, rekey promptly. Our 6:30 a.m. start every day can fit a rekey before you head out on 19th Street, or an evening visit after you get back.
Clinics and medical offices keep patient records and medications behind keyed doors, so a lost key there can raise privacy and compliance questions beyond the lock itself. Tell your practice manager right away. We rekey suite doors, records rooms and supply closets in Upland with the owner's or manager's authorization, and can suggest restricted keys that staff can't duplicate at a hardware store.
Downtown offices and storefronts often run older master key systems with keys handed out over many years. If you lose a key that opens your suite, a back corridor or a shared building entrance, tell the building manager first. We rekey cylinders you control in Upland after the owner or an authorized manager approves, and can help restructure a master system when one lost key exposes too many doors.
Situations this covers
- For example, a family on a lake trip watches the house keys slip off the dock into deep water. Nobody is ever going to use those keys. Here the honest advice is a spare, not a rekey: we cut new keys from a surviving copy, or decode a lock if none exists, and the cylinders stay exactly as they are.
- For example, a renter in a Upland Hills Estates fourplex loses keys at a concert and emails the property manager that night. The manager approves an outside locksmith in writing. We verify the lease and the approval, rekey the unit's deadbolt and knob, cut three keys and leave a sealed copy for management, while the building's other units stay untouched.
- A typical evening call: a gym locker near Benson Avenue is pried open, and the bag inside held house keys and a car registration. The car is still in the lot, but the home address isn't private anymore. We'd rekey the house that evening, entry doors before the side gate, then talk through erasing the missing fob from the car's immobilizer.
- For example, a shopper in Upland turns from the trunk to find her purse gone from the cart, with her license, house keys and a garage remote inside. After the police report, a typical plan starts at the house: rekey the front deadbolt and knob plus the garage entry door first, then the back slider's cylinder. She clears the opener remotes herself while we cut four new keys.
From your call to the finished job
- Secure the house tonight. Your first job isn't calling us, it's closing the obvious openings. Engage any interior-only lock you have, disable the garage opener if a remote went missing, and move valuables out of sight of windows. If the theft just happened and you feel unsafe, call the police first.
- Inventory the missing ring. Think beyond keys. Was there a garage remote, a gate fob, a car key, a tag with your street, or a wallet nearby? Each item expands the job slightly and changes how soon we should be there, so the list is worth five quiet minutes before you pick up the phone.
- Call with the details. On the phone we'll ask a few practical questions: Kwikset, Schlage or something else? Knobs, levers, deadbolts? A smart lock? Any spare key at all? Your answers decide which pins and tools come along, and we quote the job before anyone heads your way.
- Verify residence and walk the doors. When we arrive, we check that you live at or own the property, using ID with the address or another document. Then we walk the doors with you, confirm which cylinders the lost keys fit, and agree on the list before any lock comes apart.
- Re-pin each cylinder and test. Each cylinder comes out, the plug is removed, and the old key pins are swapped for a new combination. We reassemble, cut your new keys, and test every lock from both sides of the door, including deadbolts that must throw fully into the strike.
- Reset the extras and count the keys. Before we leave, we go back to the inventory: garage opener remotes erased, keypad codes changed, mailbox and gate handled, car key next steps clear. Then we count the new keys and note who holds each, so if one goes missing later, you know the exposure immediately.
How we quote the job
- How many cylinders the lost key opened. Every keyed cylinder is its own piece of work: the deadbolt, the knob below it, the garage entry lever, the gate. The more of them your lost key ran, the larger the quote. We'll count them with you over the phone, then confirm on site before any work begins.
- Lock brand and cylinder type. Mixed hardware is common: a Schlage deadbolt the previous owner added, Kwikset knobs from the builder, a Yale smart lock on the front. Each brand uses its own keyway, so getting everything onto one new key may mean swapping a cylinder or two. We'll show you that trade-off before quoting.
- Extras that were on the same ring. Mailbox cam locks, padlocks, gate locks and a car key all add to the visit. Some are inexpensive swaps; a transponder or smart car key involves cutting and programming that's priced separately. We list each item on the quote so you can decide which to handle now and which can wait.
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 Upland.
Practical tips before you call
- A garage remote clipped to the visor of a car parked outside is a common weak point, because the registration in the glove box supplies the address. The opener buttons built into many cars are less obvious to a thief, and erasing the opener's memory cancels them if the car is ever stolen.
- A Bluetooth tracker on your key ring can find a set dropped in a parking lot or left at a friend's house. It won't tell you whether someone copied the keys in the meantime, but it shrinks the number of truly lost rings, and the rekeys that follow them.
- If a key goes missing at a store, gym, school or office, call their lost and found before you call a locksmith. Leave a description and your number. Keys recovered the same day, from a place you trust, may turn an urgent rekey into an optional one.
- Ask for a few extra keys during the rekey rather than duplicating them later at a kiosk. Keys cut to code on the same machine tend to run more smoothly than copies of copies, and you'll know exactly how many exist from the first day.
Mistakes to avoid
- Ignoring the mailbox key. People rekey the house and forget the little key that opens a box full of bank statements and new cards. If it was on the lost ring, arrange a mailbox lock change through whoever owns the box.
- Waiting for the keys to turn up before doing anything. Hoping is reasonable for a few hours, but if theft is involved or an address was attached, every day of waiting is a day someone else might use them. Secure the doors with interior locks while you decide.
- Hiring the first number in a search without checking the license. California locksmith companies are licensed by BSIS, and anyone can look up a license at search.dca.ca.gov. Ours is LCO7891. Get a quote before work starts, and be wary of a vague phone estimate that balloons at the door.

Frequently asked questions
I rent. Can I rekey my apartment after losing my keys?
Usually only with your landlord's approval, and most leases expect management to keep a working key. Report the loss in writing first. Some properties send their own vendor; others approve an outside locksmith. With written approval, we'll verify your lease, rekey the unit, and cut a key for the office. Protective-order lock changes are a separate situation with their own rules under California law.
Should I rekey or replace my locks after losing keys?
Rekey, in most cases. A rekey changes the internal pins so the lost keys stop working while your existing hardware stays in place, and it costs much less than new locks. Replace only when a lock is worn out, damaged, too weak for its door, or when you wanted a different style or a smart lock anyway. We'll tell you honestly which applies to each door.
Should I worry about the mailbox key I lost?
Yes, especially if your address can be tied to it. Mailboxes receive bank statements, replacement cards and checks. For a box on your own property, we can usually swap the lock during the same visit. For a cluster box, who changes the lock depends on ownership: the Post Office handles boxes it owns, and an HOA or property owner handles the rest.
My car key was on the same ring. Can you help with that too?
For many vehicles, yes. We can cut and program a new transponder key or fob on site, and on many models erase the lost key from the immobilizer so it no longer starts the car. Some makes and model years require dealer programming, and we'll tell you before you book. We verify ownership before making any car key, so have your registration or title and ID available.
Can you rekey if I lost every key I had?
Yes. Without a working key, we pick or decode each cylinder to remove the plug, then re-pin it to a new combination and cut keys in the van. It takes longer per lock than working from a spare, and a few cylinder designs resist it, in which case we may recommend a replacement cylinder. If you're also locked out, we handle entry first, after confirming you live there.
How long does a rekey after lost keys take?
With a working key, each standard cylinder goes quickly, and a typical house with several doors is usually finished in a single short visit. Without a key, add time for picking or decoding each lock. Smart locks, high-security cylinders and mailboxes add a little more. When you call, tell us how many locks are involved and we'll give you a realistic estimate.
How far is Upland from your base?
Upland is about 24 miles from our San Bernardino base, roughly 30 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.
