Commercial Lock Rekey in Ontario: Rekey, Recore or Replace?
Short answer: A rekey doesn't change copies of the new key, electronic credentials, alarm codes, keypad codes or safe combinations. It only retires the old keys for the cylinders we re-pin. If your Ontario business also uses a keypad, fobs or a landlord's master, those need their own steps. We list every opening and explain what each change covers. Call (951) 903-3193.

Business owners often ask whether it would be easier to buy new locks. Sometimes it is, but a commercial lock rekey frequently costs less, because the expensive parts of a lock, meaning the body, the trim and the door prep, are usually fine. What has failed is the key, which has been copied, lost or handed to someone who has left. New hardware still needs new keys cut and every door tested. We help you compare both options door by door, and we recommend replacement when the lock itself is worn, residential grade or out of code. Call (951) 903-3193 and we'll look at what you have in Ontario.
What to know first in Ontario
Here is the honest list. A commercial lock rekey changes which keys operate the cylinders we touch, and it retires every old key for those cylinders. It does not change copies of the new keys, so key control after the job matters as much as the job itself. It does not change the PIN on a keypad lock, the codes on your alarm panel, the credentials on a fob or card system, or the combination on a safe or cash drop, though we can often change a keypad code or safe combination at the same visit. It does not affect a lock we didn't open, such as a roof hatch, a back gate padlock or a cylinder the landlord controls. And it can't fix a door that doesn't latch, a hasp screwed on from the outside or a window that opens without a key. We go through your doors and tell you what the rekey will cover and what it won't, so you can decide what to add before we pack the van.
What we can do on-site
- 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.
- Rekeying under a landlord's building standard. Suite doors in office and industrial parks can sit on a master key you don't control. When the landlord's master is the problem, your options are to ask the landlord to re-master, to add a second, tenant-controlled lock where the lease allows, or to leave the suite door alone and secure the interior doors instead.
- Moving to a restricted keyway. A rekey can't change a lock's keyway; it only changes the pins inside the slot. To move to a restricted, copy-controlled keyway we replace the cylinders. The upgrade makes sense on doors with the most key holders, or wherever lost keys have already caused trouble.
- Forgotten openings that stay on the old key. Desks, file cabinets, display cases and mailboxes use small cam and wafer locks. They aren't in the same league as a door cylinder, but a cash drawer or a records cabinet may matter a great deal. We rekey or replace them as needed and note which are worth bringing onto your system.
- Alike, different and master: planning which doors share a key. Before we pin anything, we sort the doors. Back-of-house doors might share one key, the front door and office another, and a manager's key might open both. Keyed-alike groups are simple; keyed-different doors need more keys. We sketch the plan with you and keep it to one page.
Local factors in Ontario
Hotels, event venues and attractions in Ontario have staff, vendors and seasonal workers coming and going, which makes tight key levels and a good log more important than the rekey itself. We separate guest-facing, back-of-house and management doors, and recommend restricted keys for storage, linen and office areas. Large hotel systems with card locks involve a different vendor. Seasonal hires make the log matter most.
Converted houses used as offices, salons or small shops in older Ontario neighborhoods often mix residential locks with commercial needs. A knob and a deadbolt from the 1960s can be rekeyed, but they may not meet commercial egress rules or hold up to staff use. We rekey what's sound and recommend commercial-grade levers or exit hardware where the occupancy and the code call for it.
Strip malls and shopping centers in Ontario often put dozens of tenants on one landlord's key system, with a storefront door, a rear service door and a stockroom per shop. When a store changes hands, the rear door is the one most often forgotten. Check your lease, rekey the rear door and the stockroom, and make sure the landlord's emergency key is the only copy outside your control.
Situations this covers
- Two partners dissolve their small design studio near Graber Olive House, and one buys out the other with the transfer set for Monday. We schedule the rekey for Sunday morning. With the buyout agreement and photo ID as proof of authority, we re-pin the entry and studio doors, and the departing partner sees the old key fail.
- Consider a tire shop near Milliken Avenue whose office door was pried open over a holiday weekend. The thief didn't get far, but the shop's spare keys were in the desk. We replace the damaged cylinder, rekey the other doors, add a reinforced strike on the office door and give the owner a short list of what else to check.
- For example, a small dental office near Toyota Arena lets a hygienist go. She returns her key, but the practice wants more than that. We rekey the front, supply room and records closet, and remind the office manager that the alarm code, the supply cabinet combination and the keypad PIN are separate changes a rekey doesn't cover.
- A facility manager at a charter school calls after losing the control key for the school's interchangeable-core locks. Because that key can pull any core, losing it matters more than losing any single door key. We recore the office wing, set up a new control key, explain how to store it and quote the other wings in phases.
How the visit works
- 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. If a lock is a poor candidate for rekeying, we show you why: a loose plug, a missing part, a keyway with no available blanks. Sometimes replacing a cylinder costs about the same as rebuilding it, and we say so honestly, so you aren't paying for labor that isn't worth it.
- 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. Cutting happens on site too. Keys are cut by code or from the first rebuilt cylinder, then tried in every lock they should open and in the ones they shouldn't. If a key binds, we recut it. A key that feels rough on day one will feel worse on day ninety.
- Prove the old keys are dead and close out. At each rekeyed door we try an old key to show it no longer turns the plug. We then hand over the new keys, a short key chart and notes on which doors were touched. The work order records who approved the job and when.
What affects the cost
- 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.
- Structure of the key system. A single key for everything is the simplest and cheapest, but it creates one point of failure. Separating staff, management and owner doors costs a little more in pin work and gives you much better control. Most small businesses land on two or three levels.
- Scheduling, access and travel. Our hours run every day from 6:30 a.m. to 11:30 p.m. Work scheduled before opening or after closing, or on short notice, can be priced differently than a planned daytime visit. Travel from our San Bernardino base also counts, and a few days' notice lets us plan the visit so the whole job can be finished in one trip.

Common errors that cost time and money
- 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.
Practical tips before you call
- 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.
- Photograph your key chart and keep a copy off site. A chart that lives only in the office drawer disappears with the office. Store a copy with your accountant or in a private cloud folder, tag keys with codes and keep the decoder separate.
- Ask whether the new keys will be restricted before you order extras. A standard key can be copied at nearly any hardware store, which can quietly undo the rekey. A restricted key costs more but keeps duplication under your authorization.
- 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.
Reaching Ontario
Ontario is about 25 miles from our San Bernardino base, roughly 33 minutes in light traffic via I-215 North to the I-15 junction at Devore. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.
We plan the drive the way a delivery route gets planned: freeway first, Haven Avenue where it makes sense, then the side streets you describe. A landmark or the color of your building helps the technician spot you.

Frequently asked questions
My landlord controls my locks. Can I still rekey?
It depends on the lease. Some landlords keep a building-standard cylinder and an emergency key and don't permit changes, while others allow tenant rekeys with a copy for the manager. Check the lease or ask your property manager, and send us the answer. We won't touch landlord-controlled cylinders without clear authorization.
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.
What's the difference between rekeying and recoring?
Rekeying changes the pins inside a cylinder you keep. Recoring applies to interchangeable-core locks: we pull the figure-eight core with a control key and install a core already pinned to the new key. Recoring is often faster across many doors, but it needs a working control key and the right core platform. We tell you which fits your locks.
How do I decide between rekeying and replacing commercial locks?
Rekey when the lock is sound, commercial grade and compliant. Replace when it's worn, residential grade on a heavy-use door, damaged or out of code, or when you want a restricted keyway, which a rekey can't provide. Julian's Locksmith examines each door, shows you the wear and writes up both options so you can compare them.
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 long does a commercial lock rekey take?
It depends on the cylinder count, the lock types and whether any need replacement. A few doors are often a single visit, while a large building takes longer or is phased. Interchangeable cores go faster than conventional cylinders. After the walk-through we give you a realistic time frame instead of a number promised over the phone.
How far is Ontario from your base?
Ontario is about 25 miles from our San Bernardino base, roughly 33 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.
