Making the Rekey a Routine Step of Every San Dimas Unit Turn

How this works in San Dimas

At the cylinder level, a tenant turnover rekey is mechanical and repeatable. For a standard residential pin tumbler lock such as a Kwikset KW1 or a Schlage SC1, the technician removes the knob or deadbolt cylinder, pushes the plug out with a follower so the driver pins stay in place, replaces the bottom pins to a new bitting, reassembles and tests. For doors keyed alike, every cylinder in the unit gets the same pinning so one key runs the entry, the patio door and the storage closet. It takes minutes per lock when the hardware is standard and in good shape. What takes time is everything around the lock: finding the unit, getting access, verifying authority, testing both keys, labeling the set and updating the record. That is why batching units into one visit saves far more than speeding up any single rekey. Plan the visit around the building, not the lock, and the per-door time stops being the thing you worry about.

Work included on a typical visit

• Setting a rekey-every-turn policy. A written policy beats good intentions. State what gets rekeyed (all exterior cylinders and any unit-controlled locks), when (after make-ready work), who authorizes it (manager or owner) and what gets recorded. We can draft that language with you, and we'll tell you honestly which parts are legal questions for your attorney.
• Re-pinning to a fresh bitting on the same keyway. The new key cut is chosen deliberately, not randomly. We change as many pin positions as the lock allows, so the old key doesn't come close to fitting, and we avoid recent cuts you've used elsewhere in the building. Details like that sound fussy, but they make the result of a rekey trustworthy.
• Keyed-alike sets per unit. A resident shouldn't carry four keys for one apartment. We key the unit's front door, patio door, storage and any internal keyed locks alike, so one key does the job. Fewer keys means fewer copies and fewer lockouts. Where hardware differs, we may use compatible pin kits or replace a lock to match.
• Hot turns: same-day move-out and move-in. When a resident leaves in the morning and the next arrives that afternoon, the rekey must slot in after the cleaners and before keys change hands. Tell us the turn dates when you book. We'll plan the window, confirm an honest arrival estimate and bring cut keys so you can hand over the set the same day.
• When your own maintenance tech does the rekey, and when to call us. We can train your team on the basics, such as testing the old key and recording the new bitting, and take the harder cases. A split like this keeps routine units quick and sends the awkward ones to someone with the right tools. You decide where the line goes, and we'll tell you where we'd draw it.

How San Dimas shapes the job

Single-family rentals in suburban San Dimas are often managed by owners or small firms that handle turns one house at a time. Each house has a front door, back door, garage side door and sometimes a gate, and each can use a different brand. Standardizing on one keyway over a few turns cuts the key ring and the time per visit. Keep a one-page key sheet for each house.

Older rental houses and fourplexes tend to carry decades of mixed hardware, and a turn is the time to see what's really there. We rekey what's healthy, flag what's worn and quote replacements that move the building toward one keyway. In older neighborhoods around Northern Foothills, painted-over strike plates and warped doors also show up, so we check how each bolt throws before closing out a unit.

Inland heat shortens the life of lock hardware in rental units: finishes fade, plastic parts crack, and warped doors strain latches. A turn is a chance to inspect every bolt and strike while the unit is empty. We rekey the cylinders, check how each latch engages, and flag the units that need weatherstripping or adjustment so the next resident isn't the one to find out.

Situations this covers

• A new management company takes over a small portfolio and inherits a drawer of unlabeled keys. The first priority is a baseline: we rekey the units about to turn and set up a unit-by-unit key sheet. From then on, each turn follows the same pattern, so within a few months the whole portfolio runs on records the company created rather than records it inherited.
• A property manager with a four-unit building near San Dimas Canyon Golf Club has two vacancies landing in the same week. Instead of two separate calls, she sends one list with both unit numbers, the lock counts and the next move-in dates. We quote the batch, schedule a single visit inside our hours, rekey both units and leave a labeled key set for each. One trip, one invoice, two units cleared.
• During a turn, the technician finds a second deadbolt on the back door that a resident installed without asking. Nobody has a key log for it. We'd remove it or key it to the unit's new set, repair the door prep, and the manager documents the unauthorized hardware with photos. After that, the turn checklist gets a new line: inspect every door for added locks.
• A model unit is used for self-showings with a keypad deadbolt. Every few weeks the codes pile up from agents, photographers and applicants. At each turn we help the manager clear the codes, check the batteries and rekey the backup cylinder. The unit is then ready for the next resident, and the manager sets codes to expire so the pile doesn't grow back.

Step by step with Julian's Locksmith

1. Add the lock step to your turn checklist. Start on your side. Name the step something specific, like lock reset, assign an owner and place it after paint, clean and repairs but before final inspection. Add a field for the date it was done. When the step lives on the checklist, it stops being forgotten during busy weeks.
2. Send the turn list. Email or call with the units due this week: unit numbers, number of exterior doors, any lock brands you know, whether doors are keyed alike or master-keyed, and the dates the next residents arrive. A shared spreadsheet works fine. The more complete the list, the more accurate the quote.
3. Quote and slot the visit. Pricing follows cylinders and units, with the details you gave us. We call out anything that could change the number, such as a master-keyed door or a restricted keyway. Then we propose a day. If you need a hot turn, say so now, and we'll give you an honest sense of what's realistic.
4. Authorization and access. California's Locksmith Act is why we ask for authority before touching a lock, even for a property you manage every day. It also protects you from someone claiming to represent an owner. Our license, LCO7891, can be checked at search.dca.ca.gov before we arrive.
5. Rekey, cut and test, unit by unit. Inside each unit, we work through the cylinders in a fixed order, re-pin to the new bitting, cut the keys and test. New key works, old key fails, master still works where one exists. We repeat that test at every lock, mark the unit complete and move to the next.
6. Close out with a key log and an invoice by unit. Hand the keys over with the resident's signature on the count, and keep a controlled set in the office. If anything looks off at move-in, such as a key that sticks, call us and we'll sort it out. A prompt follow-up is part of the service, not an extra.

How we quote the job

• Hardware standardization. A property with one brand and keyway throughout turns faster than one with a mix. Standard parts, familiar pin kits and predictable cylinders mean fewer surprises and less time per unit. If your hardware varies, standardizing during turns, one door at a time, lowers the cost of every future rekey.
• Key system: different, alike or master-keyed. If you're considering moving to a master system, restructuring an entire building is a different project from a turn rekey and is priced as one. Don't try to fold it into a single unit turn. We can walk the building, describe what a system would involve and give you an honest sense of scale.
• Lead time and the vacancy window. Emergencies happen, such as a hot turn where the inspection slipped or a lock found failing the day before move-in. We'll tell you how fast we can honestly get there and what the visit will cost before we drive. Same-day work isn't always possible, and we won't pretend otherwise.

Common errors that cost time and money

• Skipping the old-key test. A cylinder that was pinned incorrectly can accept both keys, and nobody finds out until a dispute. Testing the old key at every door takes seconds and proves the work was done. Write the result on the work sheet so the proof outlasts your memory.
• Rekeying before the make-ready is done. Paint, dust and adhesive end up in the cylinders, and a new key can get stiff within weeks. Contractors who already hold cut keys keep access, too. Schedule the lock step after the last trade and before the final inspection.
• Waiting for a problem to prompt the rekey. A turn without a lock step becomes a policy by accident, and the first time it matters is the day a former resident's key shows up in a complaint. Decide once, write it down and follow it.

Advice before you book

• Photograph the hardware in every unit the first time we visit. Faceplates show brand and model, and the door edge shows backset and bolt style. Those photos let us bring the right parts on later turns and make quotes for new staff or vendors far more accurate.
• Treat contractor keys as part of the policy. Painters, cleaners and carpet crews hold keys during a turn, so the rekey should come after they finish, not before. Track who has a temporary key and collect it before the permanent set is cut.
• Review your lock records once a year. Which units turned most often, which doors needed repair, which hardware aged badly? A short annual review points to the hardware worth replacing and the units that deserve a better lock. A tenant turnover rekey routine gets cheaper when the locks themselves improve.
• Put the tenant turnover rekey on the move-out checklist and the turn board with its own name, such as lock reset. A task with a name and an owner gets done; a task everyone assumes someone else did gets skipped. Review the board each week for units that are ready except for locks.

Getting to San Dimas
