West Covina, Los Angeles County
Commercial Rekey Projects in West Covina, Planned Door by Door
Short answer: Commercial rekeys in West Covina can be scheduled before tenants arrive or after they leave. Julian's Locksmith works every day from 6:30 a.m. to 11:30 p.m. Buildings on interchangeable cores often need far less time on site, because new cores are pinned in the van and swapped at each door with a control key.

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 West Covina 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.
Commercial Rekey in West Covina: what to expect
How a building is cored decides how a commercial rekey feels. With conventional fixed cylinders, every cylinder has to come off the door, be disassembled, re-pinned and reinstalled. With interchangeable cores, the hardware stays mounted and only a figure-eight-shaped core comes out, released by a control key. Small format cores, the A2 and A4 pinning systems used by Best, Falcon, Arrow and others, and large format cores from Schlage, Sargent, Corbin Russwin, Yale and Medeco both follow this idea. For a rekey, that means new cores can be pinned ahead of time and swapped at each door in moments, which makes IC buildings well suited to frequent tenant turnover. The trade-off is the control key: anyone holding it can pull any core in the system, so it needs tighter custody than any master key. If your property has fixed cylinders and you rekey often, ask whether converting the high-turnover doors to IC housings is worth it. Julian's Locksmith can explain both approaches and quote each so you can compare them on paper before deciding.
Work included on a typical visit
- Mortise cylinder rekeying. A mortise cylinder only works if its cam matches the lock body behind it. When we rekey these cylinders, we keep each cam paired with its own cylinder, check that the cylinder seats to the right depth against the trim, and tighten the set screw so nobody can spin the cylinder out from the hallway side.
- Rim cylinders on exit devices and night latches. Cylinder-dogged exit devices let staff hold the latch retracted during business hours with a key instead of a hex wrench. Those dogging cylinders belong in the keying plan too. We rekey them along with the trim cylinders so the right people can dog and undog the bar, and nobody outside that group can.
- Storefront and Adams Rite cylinders. Aluminum storefront doors usually lock with an Adams Rite deadbolt or deadlatch operated by a mortise cylinder with an Adams Rite cam. We rekey the outside cylinder and, on double-cylinder setups, the inside cylinder too, then check that the hook bolt throws fully into the frame keeper.
- Construction keying conversion. New buildings and tenant improvements are commonly delivered on construction keying so trades can move freely. Before occupancy, those cylinders need to switch to the owner's permanent keying. We replace temporary construction cores with permanent ones or re-pin construction-keyed cylinders, then cut the owner's keys and record the system.
- 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.
How West Covina shapes the job
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.
Medical office buildings mix ordinary suites with rooms that hold medications, records and equipment. When a practice leaves a suite in West Covina, 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.
Inland summers bake metal doors and the cylinders inside them. In West Covina, south- and west-facing commercial doors often show dried-out cylinders, gummy lubricant and storefront locks that stick in the afternoon. During a commercial rekey we clean each plug, use a dry lubricant that won't collect dust, and check that heat-swollen doors still let deadbolts and hook bolts throw fully into their strikes.
Common situations
- Picture an HOA management company responsible for a clubhouse, a pool equipment room and a maintenance shed after the groundskeeping vendor is replaced. The old crew had one key to all three. We'd rekey the equipment room and shed to a new vendor key, keep the clubhouse on the board's key, and leave the pool gate alone, since residents carry that key and the vendor never had it.
- Picture a light-industrial unit off Garvey Avenue North and South 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.
- 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.
- Imagine a car dealership service department where a key to the parts room went missing during a busy month. The showroom and sales offices aren't affected. We'd rekey only the service-side cylinders, cut a limited number of new keys for the service manager and parts lead, and suggest restricted blanks so nobody can copy them at a hardware counter.
Step by step with Julian's Locksmith
- Scope call. The first conversation covers what's driving the commercial rekey and who's behind it. A tenant departure, a lost master, a contractor handover and a portfolio cleanup each lead to different plans. Tell us who owns the building and who's ordering the work, since those may not be the same party.
- Authorization and site walk. Larger properties get a written door list during the walk: location, hardware type, cylinder type, keyway and the key each opening should take afterward. That list becomes the keying schedule. Smaller jobs, such as a single suite, can usually be scoped and rekeyed in the same visit.
- Keying plan and quote. The quote breaks out cylinder rekeys, cores, padlocks, keys and any replacement hardware, so you can trim or add items. If the property needs restricted blanks or a keying chart drawn up from scratch, that shows as its own line. Nothing gets added on rekey day without your sign-off.
- 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. Before we leave, you can walk the property with your new keys if you want to. Afterward, keep the keying record somewhere secure and update it whenever keys are issued or returned. That record is what makes the next commercial rekey quick and accurate instead of starting over.
What affects the cost
- Interchangeable cores versus fixed cylinders. Fixed cylinders take more labor per door: removal, disassembly, pinning, reassembly and reinstallation. On a small property the difference hardly matters. On a building that turns tenants over often, that extra labor repeats at every turnover, which is when an IC conversion starts to deserve a serious look.
- Timing, phasing and access. Work scheduled comfortably inside our normal hours costs less than a rush job squeezed into one evening. Phasing a big property across several visits adds trip time, while doing everything at once may need more hands. We'll lay out both options so you can weigh disruption against cost.
- Cylinder condition and extra parts. Old commercial cylinders sometimes fight back. Seized plugs, worn chambers, broken cams or cylinders painted over by a previous contractor take longer and may need replacement. We price those exceptions separately and show you each one before swapping it, so the base rekey price stays clear.

Practical tips before you call
- 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.
- 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.
- 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.
- Ask for Do Not Duplicate stamping if you like, but don't treat it as protection, since plenty of key counters ignore it. Real duplication control comes from restricted or patented keyways whose blanks are sold only through authorized channels, paired with a signed record of who requested each copy.
Common errors that cost time and money
- Cutting too many keys. Ordering a dozen spares just in case puts unlabeled keys in drawers, glove boxes and truck consoles. Cut what current key holders need plus a small, logged spare set, and cut more later when someone actually needs one.
- Adding a key-locking deadbolt to the inside of an exit door to tighten security during the rekey. Building and fire codes generally require exits to open from inside without a key or special knowledge, with only narrow exceptions that come with signage and conditions. Egress function is a code question, not a keying choice.
- 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.

Frequently asked questions
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.
Can you rekey a building that has no keying records?
Yes, though it takes more time at the start. We decode representative cylinders and, where needed, take a few apart to learn the existing bittings and any master pinning. From there we either rebuild the existing system on paper or design a fresh one. Either way, you finish the commercial rekey with documentation the property didn't have before.
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.
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.
Is rekeying enough after a dispute with a tenant or employee?
Rekeying stops old keys from working, which handles the mechanical side. Also think about alarm codes, keypad and access control credentials, gate remotes and shared passwords, because a rekey doesn't touch any of those. If the situation involves threats or damage, contact law enforcement first. For the locks themselves, we can usually schedule promptly once your authorization is confirmed.
Can you rekey one suite and keep the building master working?
Yes, as long as we can work from the existing keying chart or decode the system reliably. The suite's cylinders get a new change key that fits inside the current master structure, so management and maintenance keys still open the suite. If records are missing, we'll explain what decoding involves before quoting, since guessing at a master system produces keys that open the wrong doors.
How far is West Covina from your base?
West Covina is about 42 miles from our San Bernardino base, roughly 47 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.
