Every Lock Reset Between Tenants in Ontario
Short answer: A tenant turnover locksmith resets every lock point in a rental between one lease and the next: rekeying exterior doors, changing mailbox and gate locks, clearing keypad codes, repairing hardware damaged during the tenancy and recording the new key count. In Ontario, Julian's Locksmith does all of it on site once the unit is surrendered. Call (951) 903-3193 to schedule.

Every day a rental sits empty costs rent you won't get back, and lock work is often the item that gets remembered last, the evening before a new tenant picks up keys. A tenant turnover locksmith fixes that by fitting into your make-ready schedule instead of fighting it. Julian's Locksmith comes to your Ontario unit, resets every cylinder to a new key, sorts out the mailbox and gate locks, repairs whatever the last tenancy wore out and hands you a labeled set with a written count. You get one visit, one invoice and a unit that's ready for the move-in walkthrough. Call (951) 903-3193 with the move-out date and we'll book a slot that suits your painters and cleaners.
Tenant Turnover Locksmith in Ontario: what to expect
There's more than one way to handle a turnover, and the right one depends on how many units you run and what hardware is on the doors. Standard rekeying, where we re-pin the existing cylinders to a new key, suits most single-family homes and small multiplexes in Ontario and costs far less than new locks. Kwikset SmartKey cylinders can be reset with a learn tool, but only if you hold a current working key, and a cylinder that was forced or fumbled mid-reset usually has to be replaced. Larger owners sometimes keep a rotation: spare cylinders pre-pinned to fresh keys and swapped in at each move-out, with the removed ones re-pinned later. Properties built with small-format interchangeable cores can change a door's key in seconds with a control key. And if a unit has mismatched brands from years of patchwork repairs, the turnover is a sensible time to standardize on one keyway so every future rekey is simpler and every lock in the portfolio takes the same blanks.
What we can do on-site
- Rekeying every cylinder to a new key. Not every cylinder deserves a rekey. If a lock is so worn that the new key drags, or the cylinder spins in its housing, we'll show you and quote a replacement instead. Most turnover locks are in decent shape, though, and a cleaned, re-pinned cylinder will keep working smoothly through several more leases.
- Keypad and smart lock resets. Codes outlive tenants. A keypad deadbolt may still hold the old resident's code, a dog walker's code and a guest code from a birthday party. We clear every user code, set a new programming or master code that only you control, and make sure the lock's mechanical override cylinder is rekeyed with the rest of the unit.
- Repairing move-out damage. Evidence of forced entry from earlier in the tenancy, such as a cracked jamb around the strike, a bent bolt or pry marks on a cylinder, goes on the work order. We repair the lock side and can install a reinforced strike, and we'll tell you plainly when the jamb itself needs a carpenter rather than a locksmith.
- Garage, gate and outbuilding locks. Perimeter keys are easy to lose track of because tenants rarely use them. We find every keyed point outside the house, including the T-handle lock on an older tilt-up garage door, and bring it onto the new key, so the incoming tenant carries one key instead of a jangling collection nobody can identify.
- Temporary vendor keying during the make-ready. During a make-ready, plenty of people need access: painters, cleaners, flooring crews, appliance techs. We can pin the cylinders to a temporary key you hand out freely, then come back before move-in to set the tenant's final key. The new resident ends up with a key no contractor has ever carried.
What's different about Ontario
Older rentals in Ontario often carry decades of patchwork: a different brand on every door, painted-over hardware, deadbolts with short throws and original mortise locks on front doors. A turnover is the right moment to tidy that up gradually. We rekey what can be rekeyed, replace worn or obsolete pieces, and note where replacement would bring the house onto one key and one keyway.
Many owners in Ontario spend long hours on the freeway, so turnover appointments have to fit around a commute. We start at 6:30 a.m. every day, which lets an owner meet us before heading to work, or skip the meeting entirely with a lockbox, written authorization and photos sent as we finish each lock point on the list.
Inland heat shows up at turnover time. Doors swell and frames shift over a long summer, so a deadbolt that threw easily at move-in may now bind against the strike. Keypad batteries drain faster in hot entryways, and gate padlocks bake in direct sun. We realign strikes, replace tired batteries and fit weather-rated exterior hardware where the old pieces keep failing.
Common situations
- Here's a request we handle carefully: rent has stopped, most of the tenant's things are still inside, and the owner wants the locks changed today. Until possession has been legally returned, through a surrender, a completed abandonment notice process or a sheriff's lockout, changing the locks can count as an illegal lockout. We'd book the rekey for the day possession is clear.
- Suppose the owner lives out of state and runs the Ontario rental from a laptop. The tenant has moved out, keys are in the lockbox, and the owner can't be on site. We'd ask for written authorization and proof of ownership before the visit, send photos of every lock as we work, and leave the new keys in the lockbox under a code the owner chooses.
- For example, a single-family rental where the last tenant installed a Wi-Fi smart deadbolt tied to their own app and moved away without releasing it. The owner can't add codes, and the former tenant has stopped answering messages. We'd remove that lock, install a standalone keypad deadbolt the owner controls, key its override cylinder to match the other doors and leave written programming steps.
- Imagine a rental in North Ontario where a lockout earlier in the tenancy was solved with a shoulder against the door. The jamb around the strike is cracked, the strike screws are only biting into trim, and the deadbolt sits loose. We'd rekey the lock, fit a reinforced strike with long screws into the framing, and advise the owner to have a carpenter replace the cracked jamb section.
Step by step with Julian's Locksmith
- Send the turnover details. A few photos save a lot of guessing. Snap the front of each lock, the keyway face of the deadbolt cylinder and the mailbox, then send them with the address. From those we can identify brands and keyways, tighten up the quote and bring the right pins and parts.
- Confirm possession and authorization. California prohibits landlords from locking out a tenant who still has the right to occupy. So we ask how the unit became vacant: a normal move-out with keys returned, a completed abandonment process or a sheriff's lockout. That single question protects you as much as it protects us.
- Walk every lock point. We test function as well as keys: deadbolts thrown with the door shut, latches catching cleanly, window latches and sliding-door locks working. A vacant unit is the easiest time to fix those, with no furniture in the way and no tenant taking time off work.
- Repair and replace what needs it. Tenant add-ons come off at this stage, with holes filled or covered where practical. Smart locks you're keeping get reset and re-enrolled; ones tied to an unreachable account get replaced with your approval. Anything outside lock work, such as a split jamb, goes into the notes for the right trade.
- Rekey and cut the new keys. If you've chosen the two-stage approach, this step happens twice: a temporary vendor key at the start of the make-ready and the tenant's final key just before move-in. The second visit goes quickly because the inventory and repairs are already finished.
- Test, count and hand off. Before leaving, we run each new key through every lock, operate the deadbolts with the doors closed and confirm keypad codes respond. You get the agreed number of keys, tagged without the address, plus a written note of what was done to each lock.
Pricing factors
- Condition and move-out damage. Damage found halfway through a job never gets quietly added to the bill. If we uncover a cracked jamb, a seized gate lock or a smart lock that refuses to reset, we stop, explain what we found and requote. You approve the extra work first, or you choose to leave it for another day.
- Keyed alike, master-keyed or high-security. Keying all the doors in a unit alike is standard and adds very little. Fitting a turnover into a master key system takes more care, because each cylinder has to follow a keying chart so both the tenant key and the manager's master keep working. Properties with no records need decoding first, which adds time to that first turnover.
- Smart locks and keypads. Clearing codes on a standalone keypad deadbolt is quick. App-connected locks take longer, because they may need a factory reset, a firmware update and re-enrollment under your account. If a former tenant's account still controls the lock and it can't be released, the cost becomes a replacement lock rather than a simple reset.
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 Ontario.
Practical tips before you call
- Reset garage door opener codes and remotes during the turnover. Most openers let you clear stored remotes and set a new keypad PIN from the motor unit or keypad; the opener's manual explains how. A garage that still opens for the old tenant's remote is an unlocked back door into the house.
- Count keys at the move-out walkthrough, not afterward. Bring the key log from move-in, collect door, mailbox, gate and garage keys from the tenant in person, and write the total on the move-out form you both sign. Missing keys are far easier to discuss while the tenant is still standing in the doorway.
- Tape over lock hardware before the painters arrive. Paint in a strike pocket or on a latch bolt is one of the most common reasons a freshly rekeyed deadbolt won't throw. Ask your painters to mask knobs, roses and strikes, or schedule the lock work after they've finished and the paint has dried.
- Standardize on one keyway across your rentals. When every property uses the same brand and keyway, rekeys go faster, blanks are always in stock, and a maintenance master can be added later if the portfolio grows. Make the change gradually, one unit per turnover, instead of replacing everything at once.
Mistakes to avoid
- Treating returned keys as proof that every key is back. Tenants hand over whatever is on their own ring, not the copies a roommate, partner or babysitter had cut. If the old key family stays live, you can't know who could still walk in. A full turnover rekey is the only real answer.
- Leaving a former tenant's smart lock in place because it still seems to work. If their account controls it, they may still be able to open the door, add codes or watch the activity log. Reset and re-enroll the lock under your account, or replace it, before the new tenant arrives.
- Forgetting the mailbox, gates and garage. Owners who rekey only the front door leave the former tenant holding a working mailbox key, gate key or service-door key. Every lock the old key opened has to change, or the turnover rekey has a gap in it that nobody notices until something goes missing.
Reaching Ontario

Frequently asked questions
What if the tenant never returned the keys?
Then a rekey isn't optional. If the tenant has surrendered the unit, we rekey every cylinder their keys opened, including the mailbox and gates. If you aren't sure they've actually given up possession, settle that first, because changing locks on a tenant who still has the right to occupy can be an illegal lockout under California law, whatever the rent situation.
Can you meet the sheriff for a lockout after an eviction?
Yes. Book us for the scheduled lockout time and we'll wait until the deputy has completed the lockout and returned possession to you or your agent. Then we rekey every exterior lock and the mailbox and secure any gates. We don't enter the unit or change anything until the deputy has formally handed it over, even if the occupant appears to have left.
Do you rekey the garage as part of a turnover?
We rekey the garage service door, the door from the garage into the house and the T-handle lock on older manual garage doors. Openers, remotes and keypads aren't rekeyed; they're reset through the opener's own memory, which you or a garage door company can handle. If you'd like, we'll show you where the opener's learn button is while we're there.
The last tenant installed a smart lock. What happens to it?
If you own it and it's registered to your account, we reset it, clear every code and re-enroll it. If it's tied to the former tenant's account and they won't release it, replacing it is usually simpler. If your lease let the tenant take their own lock with them and they left holes or mismatched hardware behind, we'll restore a proper deadbolt keyed to the unit.
Should I rekey or replace the locks at turnover?
Rekey whenever the hardware is in good shape, because it costs far less and the unit looks exactly the same. Replace when a lock is worn, damaged, obsolete or too flimsy for rental use, or when you're moving a property onto one keyway. During the walk-through we'll tell you which locks fall into which group and quote both options whenever the decision is close.
Do you work weekends, including Saturdays?
Yes, we're open Saturdays and Sundays. Our hours are 6:30 a.m. to 11:30 p.m. every day of the week. For a Saturday move-in, we can be on hand that day, or you can book the turnover for Thursday or Friday morning and leave the new keys in a lockbox.
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.
