Rekey Your Business Locks in North Fontana and Retire the Old Keys
Short answer: Rekey when the lock body is sound and only the key's secrecy is the problem. Replace when the lock is worn, damaged, residential grade on a heavy-use door or out of code. Julian's Locksmith examines each commercial door in North Fontana, shows you the parts that argue for replacement and prices both choices side by side before work begins. Call (951) 903-3193.

A commercial lock rekey sounds like a big job, but what happens inside each cylinder is small and precise. A pin tumbler lock holds stacks of pins on springs; the right key lifts every stack to the shear line so the plug can turn. A rekey swaps the key pins for ones that match a new key, so the old key now lifts the stacks to the wrong heights and the plug stays put. The door, the lock body and the trim all stay where they are. For a business in North Fontana, that means new keys, dead old keys and little downtime. Julian's Locksmith does this on site with a mobile bench. Call (951) 903-3193 and tell us how many cylinders you have.
How this works in North Fontana
A rekey only matters if the new keys stay under control. That starts with the keyway. A standard keyway can be copied at nearly any hardware store, so the number of copies can grow without you ever knowing. Restricted keyways, such as patented profiles, require authorization to duplicate, so copies pass through you. Next comes the structure: which doors share a key, which have their own, and whether a master or manager's key sits above them. Last is the record: a short list of who holds which key, coded rather than labeled with the door's name. Before we leave, we test every door with the new key and with an old key to show that the old one fails. We hand you the keys, a short key chart and our notes on which doors we touched. Ask us about a signed key log for employees; it's a small habit that makes the next change cheaper.
Work included on a typical visit
- Re-pinning cylinders on site. Most commercial cylinders can be re-pinned at the door. We remove the cylinder, strip the old pins, rebuild it to the new key's cuts, reinstall it and test the key before moving on. Because we work from the van, you aren't left without a door while a part goes out to a shop.
- Doors that also have electronic parts. Smart and keypad locks offer a chance to retire keys altogether, but a mechanical backup remains on many models, and that cylinder is a hole in the plan if it stays on the old key. We rekey those backup cylinders so the override matches your current key system.
- Moving to a restricted keyway. Restricted systems from makers such as Medeco, Mul-T-Lock, ASSA ABLOY and Schlage Primus use blanks that aren't sold over the counter and duplicate only with authorization. We tell you which profiles we can supply and cut, how long blanks take to arrive and what the system adds per key before you commit.
- Forgotten openings that stay on the old key. Rekey lists tend to leave out roof hatches, electrical and riser rooms, sprinkler closets, alarm-panel boxes and key switches. Those cylinders are often decades old and still on keys handed out long ago. We look for them on the walk-through and quote them with the main doors.
- Proof that the old keys are dead. After the visit, you can run your own check. Keep one old key per door, label it and try it again a week later. If any works, call us. We'd rather learn about a missed cylinder from you than from a break-in report.
How North Fontana shapes the job
Summer heat across inland Southern California dries out cylinders and expands metal. Exposed rear-door cylinders and gate padlocks take the worst of it and can seize or bind right after a rekey if they were already marginal. We clean and lubricate each cylinder with a dry lubricant, test it warm when we can and replace cylinders on exposed doors that show wear.
Child care centers, tutoring studios and small schools in North Fontana's family neighborhoods have to balance security with quick, safe exits. Keep key levels simple, put a thumbturn or lever on exits so staff never need a key to leave, and rekey when a teacher or volunteer leaves. We check that exit hardware works for small hands and adult hands alike.
New commercial buildings in North Fontana are often turned over with construction keys that the contractor, subcontractors and sometimes the developer's team still hold. A final rekey before opening is the standard way to retire them. We cut the permanent keys, collect the construction set against a sign-off and record both, so the tenant starts with a clean, documented system. Ask the builder for the construction keying records.
Example situations
- A typical call: an auto repair shop near SR-210 has three bay doors, an office and a parts room, each on a different key left behind by three owners. The current owner wants fewer keys on every ring. We identify the keyways, re-pin the compatible cylinders to one shop key, swap two worn ones and give the office its own key.
- A boutique near David W. Long Elementary School wants its locks changed before Monday's opening. Sunday is a working day for us, so we start at 6:30 a.m., rekey the front, rear and stockroom doors, test each with an old key and leave the new keys with the owner by midday. The shop opens on schedule without a closed sign.
- A boutique gym has a rear door whose key sticks and whose cylinder spins part way before catching. The owner asks for a rekey. We explain that the cylinder is worn out and recommend replacement, pinned to the same new key as the front door. The owner agrees, and both doors end up on one key that turns smoothly.
- A franchise owner finishes a build-out in a shopping center and receives a ring of contractor keys along with the permanent set. Before opening, we pin the entry, stockroom and office to a final set of keys, collect the contractor's keys against a sign-off and hand the owner a one-page chart showing which key opens what.
From your call to the finished job
- List every opening. Include doors you don't control, such as suite doors the landlord keys, and tell us who holds the master. It's better to know what we can't change than to find out halfway through the job. We'll mark those on the list and leave them alone unless authorized.
- Identify the cylinders on site. On arrival we look at each cylinder: brand, type, keyway and condition. Many carry the maker's name around the face. We try a key, check the cam or tailpiece and note any wear. That inventory decides which locks can be re-pinned and which need to be replaced.
- Decide rekey, recore or replace, door by door. You make the final call. A door that's rarely used and in good condition might wait for a later phase, while a door that has failed or leaks risk goes first. We write the plan down as a short list, so you can approve it, change it or ask questions.
- Choose the key system and quantities. Next we decide how many keys, of what kind, for which doors. Standard keys are quickest; restricted keys add control. We sketch which doors share a key and who gets which, and we confirm how many copies you want cut now. Extra copies cost less at this visit than later.
- Re-pin, cut and test. We work from the van. Each cylinder comes out, gets rebuilt to the new key, goes back in and is tested with the new key before the next one starts. Doors are never left open or unlatched, and we ask you which entrances must stay usable during the work.
- Prove the old keys are dead and close out. We also give you a close-out list: collect old keys, update alarm and keypad codes, review credential lists and decide who holds spares. Rekeying is the central step, but these small tasks complete it. If you'd like, we'll walk through the list before we leave.
How we quote the job
- Cylinder family and pin count. Common commercial families, such as standard mortise and rim cylinders, come with readily available pins and blanks, which keeps the job straightforward. Less common keyways or proprietary lines take longer to source and sometimes need factory-held parts. We tell you early if your cylinders fall into that group.
- Re-pinning versus replacement parts. Sometimes the lock body, not the cylinder, needs attention: a bent latch, a worn cam or a loose rose. We quote those fixes separately and only with your approval. Doing them at the same visit saves a second trip, but you never owe us for repairs you didn't agree to.
- Scheduling, access and travel. We drive from our base in San Bernardino, and travel time is part of any quote. Grouping the work into one visit keeps it down. Tell us if your building has controlled parking, a guard desk or gate codes so we aren't stalled at the entrance.
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 North Fontana.
What to do before we arrive
- Treat an interchangeable-core control key like a master. Keep it locked up, give it to one or two people and write down who holds it. Anyone with a control key can pull cores, so losing one is a bigger event than losing a door key.
- Don't rekey a lock that is failing. If the key sticks, the plug spins or you have to jiggle the door, say so when you call. We'll test it and probably recommend replacement. A new key in a worn cylinder is still a worn cylinder.
- After the rekey, test every door yourself. Use the new key from outside, the thumbturn or lever from inside, and let the door close on its own. A latch that doesn't catch is a security gap the new key can't fix. Call us right away if anything feels off.
- Look for double-cylinder deadbolts, chains, hasps or padlocks on exit doors. They block escape, and a fire inspector will flag them. Mention them during the visit. We can swap them for hardware that opens without a key from inside while keeping the outside secure.
What not to do
- Assuming a rekey stops copies of the new key. It retires the old keys, but a standard key can be duplicated at nearly any store. Choose restricted keys for doors with many holders and log who has each one, or the problem returns within a year.
- Rekeying only the front door. Back doors, loading docks and roll-up gates are where intruders head because they know owners overlook them. Include every exterior opening and any interior door that guards cash, records or stock. Walk the list once in daylight and once after closing, when forgotten doors tend to show themselves.
- Choosing the cheapest keyway and then handing out keys freely. When any hardware store can copy your keys, the number of copies drifts upward without you knowing. Spend a little more on restricted blanks where many people hold keys. The price difference per key is small next to the cost of redoing the job later.

Frequently asked questions
Can all commercial locks be rekeyed?
Most can, but not all. Standard mortise, rim, key-in-lever and interchangeable-core cylinders are usually rekeyable. Worn or damaged cylinders, locks with discontinued keyways and some inexpensive padlocks and cam locks aren't worth rebuilding or can't be. We test each lock first, tell you which to rekey and which to replace, and price both paths.
What if my business uses a master key system?
Rekeying a master-keyed lock takes extra care because each cylinder carries master pins. We can change individual cylinders, re-master a set or build a new hierarchy. We need your key records or permission to decode the existing system. We explain the scope before pricing, since master systems affect every cylinder.
Can exit devices and panic bars be rekeyed?
The cylinder on an exit device's outside trim or dogging can be rekeyed like any other rim or mortise cylinder. The device itself doesn't change. We also check that the bar releases freely from inside, because egress rules require that. If the device is damaged or worn, we can quote a repair or replacement.
How many keys do I get, and who can copy them?
You decide how many keys we cut. We cut by code on site and test each one. Whether others can copy them depends on the keyway. Standard keys can be duplicated at most hardware stores, while restricted keys require authorization from you. For doors that many people hold keys to, we recommend restricted blanks and a simple log.
Will my old keys really stop working?
Yes, for every cylinder we rekey. After the work we try an old key at each door to show that it no longer turns the plug. Locks we didn't touch stay on their old keys, so the door list matters. Keep one old key per door for a week and test it yourself, then call us if any still turns.
What proof do you need before rekeying my business?
We verify that you have the right to authorize the work. A lease, deed, business license or a letter from the owner or manager, plus photo ID, usually does it. An employee can call on the owner's behalf if the owner approves in writing. We note what we saw on the work order. You can check our license, LCO7891, at search.dca.ca.gov.
How far is North Fontana from your base?
North Fontana is about 14 miles from our San Bernardino base, roughly 19 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.
