Glendora, Los Angeles County
Commercial Rekey Projects in Glendora, Planned Door by Door
Short answer: Before you book a commercial rekey, have three things ready: an approximate count of doors and padlocks, any keying chart or bitting list a previous locksmith left, and proof that you own or manage the property, or a signed authorization from the owner. With those in hand, Julian's Locksmith can quote a Glendora job accurately and arrive with the right keyways and parts.

The hardest part of a commercial rekey usually isn't the pinning. It's working around people. Medical suites see patients until evening, warehouses run shifts, and retail tenants won't accept a storefront that's open to the sidewalk during business hours. Julian's Locksmith plans Glendora commercial rekeys around those windows. We can start at 6:30 a.m. every day, work into the evening until 11:30 p.m., and break a large property into phases so no door is left without a working lock overnight. Tell us which spaces are occupied, when each tenant opens, and where the building's master key needs to keep working, and we'll build the schedule from that.
How this works in Glendora
Commercial rekeys carry responsibilities that residential work doesn't. First, authority: we need to see that you own the building, manage it, or hold written authorization from someone who does, because California's Locksmith Act and the Bureau of Security and Investigative Services expect licensed locksmiths to confirm who is entitled to the work. Tenants should also read their lease, since many commercial leases require landlord consent before locks change and a key handed to the landlord afterward. Second, codes: a rekey alters only the cylinder, so exit devices, fire-rated door hardware and accessible levers keep working exactly as they did. That's one reason rekeying is safer than swapping in random hardware. Third, limits: rekeying won't fix a door that drags, a closer that slams, a strike that no longer lines up, or an access control panel full of stale user codes. We point those out during the commercial rekey so you can decide whether to deal with them now or later. Julian's Locksmith holds California license LCO7891, which you can confirm at search.dca.ca.gov.
How we can help in Glendora
- Rim cylinders on exit devices and night latches. Rear service doors and stairwell exits usually carry a rim cylinder that controls outside entry through the panic bar trim. If keys to that door have wandered, the building is open to anyone holding one. Rekeying the rim cylinder closes that gap without touching the exit device itself or its fire listing.
- Interchangeable core rekeys. The control key is the most sensitive key in an interchangeable core system. As part of an IC rekey, we'll ask who currently holds it. If a control key went missing, the safe move is a new control bitting across the system, since anyone holding the old one can remove cores whenever they like.
- Tenant suite turnover rekeys. The goal of a suite rekey is to cut off the outgoing tenant without disturbing anyone else. We check which shared doors the old tenant could open, such as restroom corridors, trash enclosures or a back hallway, and decide with you whether those need their own rekey or a separate common-area key.
- Roll-up doors, padlocks and yard gates. Padlocks are where key control quietly fails. A building can be rekeyed perfectly while the yard gate padlock still opens with a key from years ago. During a commercial rekey we list every padlock, separate the rekeyable models from the throwaway ones, and bring the whole set onto the new key or keying plan.
- Phased rekeys and keying records. Inherited a building with no records? We can rebuild them. By decoding cylinders during the rekey, we establish what the system actually is, not what someone remembers it to be, and document it going forward. That turns the next tenant change into a planned task instead of a scavenger hunt.
How Glendora shapes the job
Medical office buildings mix ordinary suites with rooms that hold medications, records and equipment. When a practice leaves a suite in Glendora, those rooms deserve their own keys under the new tenant, not a single key every staff member carries. We rekey around patient hours, usually before the clinic opens or after the last appointment, and keep the building master working so property management and engineering access stays the same.
Parts of Glendora with older housing usually have older commercial buildings close by, often with original mortise hardware, brass rim cylinders and keys stamped with numbers nobody can trace. Those locks are frequently still sound and worth rekeying rather than replacing. We clean and re-pin them, replace the few cylinders that are too worn, and document the result, since older properties tend to have the thinnest key records of all.
Plenty of building managers and owners drive in from elsewhere in Los Angeles County, so timing a commercial rekey around when a key holder can be on site matters. We start at 6:30 a.m. every day, which lets us finish a suite before tenants arrive, and we can work into the evening for buildings that clear out late. Tell us when your contact will be there, and we'll plan the visit around that window.
Situations this covers
- A typical older-building job: a single-story office from the 1970s with original mortise locks and keys stamped with a number nobody can trace. The new owner wants fresh keys and real records. During the commercial rekey we'd decode a cylinder or two, clean the gummed-up plugs, replace any seized cylinders outright, and document the new system so the next owner doesn't start from zero.
- Picture a light-industrial unit off Glendora Avenue with two roll-up doors, an office entrance and a rear man door. The outgoing tenant left padlocks on the roll-ups and took the keys. After confirming the landlord's authorization, we'd remove those padlocks, rekey the office and man-door cylinders, and fit new rekeyable padlocks on the same key so the incoming tenant carries just one.
- For example, a property manager oversees a two-story office building off Foothill Boulevard where a law firm just vacated a second-floor suite. The firm returned four keys, but the lease ran seven years. We'd rekey the suite entry and its three interior doors to a new change key, keep them on the building master, and confirm the old keys still fail at the shared restroom corridor, which stays on its own common key.
- For example, a general contractor finishing a tenant improvement in a newer business park calls to schedule the keying turnover. The cylinders shipped with construction cores, and a dozen trades have held keys. After the final inspection, we'd swap in permanent cores pinned to the owner's keying schedule, cut the owner's keys, and leave the contractor's crew holding keys that open nothing.
Step by step with Julian's Locksmith
- Scope call. If you have them, send photos of a few cylinders and the keys you carry today, plus any keying chart from a previous locksmith. Even a picture of a key's stamped number helps. It lets us bring the right blanks and pinning parts rather than discovering the keyway at the door.
- Authorization and site walk. On the walk-through we look at each door's hardware, not just its cylinder. A sagging closer, a strike that's out of line or a loose lever won't be fixed by rekeying, and it's better to know before keys are cut. Every observation goes into the quote so you decide what to include.
- Keying plan and quote. For buildings with existing master keying, the plan respects what already works. If your management master opens every suite today, it should still open them afterward. We'll show which keys change and which stay, so tenants and maintenance staff know what to expect before anyone's key stops working.
- Scheduling around occupants. Occupied buildings need notice. We'll suggest giving tenants a short heads-up with the date, the doors affected and how they'll receive new keys. When a suite can't spare its entrance during business hours, we rekey it first thing in the morning or after close.
- Rekeying and testing each opening. When we find a cylinder that won't hold a new combination, such as one with worn chambers, a cracked shell or a broken cam, we stop and show you before replacing it. You decide whether to swap that cylinder now or leave the door for a later visit.
- Keys, records and handoff. Handoff is also when we review key custody: who holds masters, who holds control keys, how spares are stored. We'll suggest a simple sign-out log or key cabinet if you don't have one. Good custody keeps a fresh rekey from going stale within months.
Pricing factors
- Interchangeable cores versus fixed cylinders. Buildings with interchangeable cores often cost less in labor per opening, because the hardware doesn't need disassembly. New cores are a parts cost, though, unless we're re-pinning the cores you already own. We'll compare re-pinning against new cores so you can choose based on quantity and condition.
- Master keying and keying charts. Each added level raises the price: a grand master over several buildings, masters per building, sub-masters per tenant, change keys per door. More levels mean more calculation and more pins per chamber. We'll suggest the fewest levels that still give each group the access it actually needs.
- Cylinder condition and extra parts. Parts beyond the pins can show up on a commercial rekey: new cams to fit a different lock body, cylinder collars or rings for a proper fit, padlock replacements, or new furniture lock cores. They're small items individually, but on a large property they add up, so we list them line by line.

What to do before we arrive
- When a building is sold, ask the seller for every key, the keying chart and any control keys at closing, then rekey anyway. The chart speeds the work and lets you keep a well-designed hierarchy, but no seller can account for every copy made over the years.
- Keep the keying chart and bitting list off site, or locked away from the general key cabinet. Anyone who reads it could have keys cut by code at a shop that doesn't ask questions. Treat it like the combination to the building, because in practice that's what it is.
- Collect old keys at tenant move-out even though you're rekeying. Returned keys tell you whether anyone held a master or a key to shared doors that wasn't on your list. If a returned key opens something unexpected, that door belongs in the commercial rekey too.
- Rekey when you change vendors, not months later. When janitorial, security patrol or HVAC contracts end, the outgoing crew often still holds keys. Schedule the rekey for the contract's last day, and issue the new vendor's keys on their first visit.
Common errors that cost time and money
- Booking from a phone price that never asked about cylinder count or hardware type. A commercial rekey priced without knowing the doors is a number that will change once someone arrives. Ask what's included per cylinder, whether keys and padlocks are extra, and get the full price before work starts.
- Rekeying the suite but forgetting the shared doors. The outgoing tenant's key no longer opens their old space, but it still opens the back corridor, the roof hatch or the trash enclosure because those were on the same key. Always check what else the old key operates before settling the scope.
- Swapping a commercial lever for a cheaper residential knob because it takes the same key. Commercial doors often need Grade 1 hardware, accessible lever trim and, on rated openings, labeled hardware. A rekey preserves all of that; mixing in residential parts can break compliance and wear out fast under commercial traffic.

Frequently asked questions
What goes into the price of a commercial rekey?
Our quote lists the per-cylinder rekey work, the number of keys, any new cores or padlocks, replacement parts such as cams or collars, and keying chart work if it's needed. We don't publish fixed prices, because the mix of hardware varies so much from building to building. We count cylinders, confirm the plan with you, and quote before starting. Call (951) 903-3193.
Do you rekey padlocks, gate locks and roll-up doors?
Yes, where the lock has a rekeyable cylinder, as many commercial American Lock and Abus padlocks do. Cheap laminated padlocks usually can't be rekeyed and are better replaced with rekeyable units on the new key. Roll-up door locks with standard cylinders can be rekeyed, while proprietary parts from a door manufacturer may need replacing. We sort all of this out during the inventory.
When can you schedule a commercial rekey in Glendora?
We work every day from 6:30 a.m. to 11:30 p.m., and we're closed overnight. For occupied buildings, early mornings and evenings usually work best, and large properties are scheduled in phases. Call (951) 903-3193 with your door count and preferred window, and we'll give you an honest estimate of when we can start.
How long does a commercial rekey take?
It depends on cylinder count and hardware type. A single suite with a few locks is often handled in one short visit. A building with dozens of mortise cylinders, exit devices and padlocks may take a full day or several phased visits. Interchangeable core buildings move fastest because cores are pinned ahead. After the walk-through, we'll give you a realistic time estimate along with the quote.
Can you rekey high-security cylinders like Medeco or Mul-T-Lock?
Often, but it depends on the system. High-security cylinders use patented keys and sometimes special pins or sidebars, and blanks may be restricted to the original dealer or the registered holder of the key system. Tell us the brand and whether you have a key card or registration. We'll explain what can be done on site and what has to go through the manufacturer's channel.
What does a commercial rekey include?
A commercial rekey changes the internal combination of your property's lock cylinders so existing keys no longer work, then supplies new keys. On a typical Glendora building that covers mortise cylinders, rim cylinders on panic bars, storefront cylinders, key-in-lever locks, and often padlocks and cabinet locks. Doors, levers, exit devices and closers stay in place. You end up with new keys and a record of which key opens each door.
How far is Glendora from your base?
Glendora is about 35 miles from our San Bernardino base, roughly 41 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.
