Rekey Locks after Buying a House in Fontana

Short answer: Yes, you should rekey locks after buying a house, ideally on the day you take possession. Sellers, their relatives, agents, cleaners and contractors may all hold copies, and none of them have to give those back. Rekeying swaps the pins inside your existing cylinders so every old key stops working. Julian's Locksmith does it on site in Fontana; call (951) 903-3193.

Rekey Locks after Buying a House in Fontana, CA — Locksmith rekeying a residential lock cylinder

Rekeying sounds technical, but the idea is simple. Inside each cylinder sits a row of small brass pins cut to match the old key. We remove the cylinder, swap those pins for a new combination, and cut you fresh keys, so the lock looks and works the same but no previous key can turn it. For most residential brands, including Kwikset, Schlage and Yale, that's a short job per lock and costs far less than buying new hardware. If you've just bought a home in Fontana, it's one of the smartest small investments you'll make in your first week there.

What to expect in Fontana

It helps to be clear about what a rekey does and doesn't do. Rekeying changes who can operate a lock. It doesn't make the lock stronger, the door thicker or the frame harder to kick in. If the deadbolt on your new home is an entry-level Grade 3 model held by short strike screws in a soft jamb, fresh pins won't change how it handles a shoulder or a pry bar. That's why a good post-purchase visit looks past the cylinder. We check whether each exterior door has a deadbolt at all, whether the bolt fully extends into the strike, and whether the strike screws reach the stud behind the jamb rather than stopping in thin trim. We look at glass near each lock, since a pane within arm's reach of a thumbturn changes the advice. For buyers who want more than a key change, the next steps are clear: security pins that resist picking and bumping, Grade 1 or Grade 2 hardware on the main entry, reinforced strikes, and restricted keyways that stop copies from being cut at any hardware counter. None of it is required. We'll explain which upgrades suit your doors and budget, then rekey the rest.

What we can do on-site

  • Whole-house rekey on possession day. We rekey every keyed cylinder in one visit, so the house goes from an unknown number of keys to only yours in a single appointment. That includes front, back, side and garage entry doors, plus keyed patio handles. You get fresh keys cut on site and can request as many copies as your household needs.
  • Garage entry and side door locks. The door from the garage into the house is the one buyers forget and burglars appreciate, since an old opener remote can lift the big door and expose it. We rekey that knob or deadbolt with the rest, and we'll tell you if it lacks a deadbolt and would benefit from adding one.
  • Mailbox lock change. A mailbox lock is a small cam lock, and the right replacement comes down to measurements: cylinder length, cam length and offset, and which direction the cam turns. We match those so the door closes flush and the cam catches the frame. On HOA-owned cluster boxes, we work only on the compartment the association confirms belongs to you.
  • Lock condition check and upgrades. A rekey visit is a natural time to evaluate the hardware itself. We check backset, bolt throw, strike plate screws and how the door sits in the frame. Some buyers stop at rekeying; others add a higher-security deadbolt on the front door or a sturdier lock on the garage entry. Your call entirely.
  • Key control after the move. Once only your keys work, keep it that way. We can cut a counted set of copies, label which key goes to which area if you keep some separate, and suggest who should hold spares. For contractors and movers, a temporary key that we rekey out afterward avoids starting from scratch later.

Local factors in Fontana

Family neighborhoods mean school schedules, carpools and a lot of people who may have held the previous owner's keys: babysitters, grandparents, coaches dropping kids off. After you buy in Village of Heritage, rekeying gives you a clean slate before your own kids start getting keys. Many families pair it with a keypad deadbolt so children never carry a key that can be lost at school.

Buying new from a builder? Construction keying is designed to lock out the trades' key once your homeowner key is first used, but confirming it worked on every cylinder is wise. Builder-grade locks are usually Kwikset or Schlage and rekey easily. Many buyers also use this visit to add a smart deadbolt or upgrade the garage entry lock while the house is still empty and easy to work in.

Inland heat bakes exterior locks. Lubricant dries, pins gum up, and keypads on sun-facing doors wear out faster. When we rekey after a purchase in Fontana, we clean and lubricate each cylinder with a dry graphite or PTFE product rather than oil that attracts dust, replace tired springs, and check keypad batteries, which hot weather drains faster than many owners expect.

Situations this covers

  • Imagine buying a home whose sellers had a Kwikset keypad deadbolt on the front and a Wi-Fi smart lock on the back door. The keypad still opens with their code, and the smart lock still shows up in their app. We'd clear every stored code, factory-reset the smart lock, pair it to your phone, and rekey both backup cylinders to your new key.
  • Consider a bank-owned home off Foothill Boulevard bought as a first house. The preservation company changed the locks at foreclosure, likely to a code shared across many properties, and the lockbox was opened by every agent who showed it. In a case like this, rekeying every exterior lock, plus checking for broken latches left over from the vacancy, would be the first job before anything else.
  • Say you buy a newly built home and assume the locks are pristine. Builders often use construction keying, where the crew's key is supposed to quit working after your first key turns. A locksmith would test each cylinder with the construction key if one is available, confirm the change took, and rekey anything that didn't. It's a short visit that replaces assumption with certainty.
  • Take a 1980s stucco home with a black steel security screen door over the front entry, keyed on both sides, plus a slider with a keyed handle. The sellers left one key for the screen door and none for the slider. In a case like this, we'd rekey the screen door to match the house, switch it to an inside thumbturn if the owners agree, and replace the slider cylinder.

Step by step with Julian's Locksmith

  1. Book around your possession date. When you call, have the property address, your possession date and a rough count of exterior doors ready. Photos of each lock face, including the brand stamped on the deadbolt, let us stock the van with the right pins and cylinders. We work every day, 6:30 a.m. to 11:30 p.m.
  2. Bring proof of ownership. Since your license won't show the new address yet, bring photo ID plus a closing statement, grant deed, escrow instructions or similar documents in your name. If the deed hasn't recorded yet, escrow paperwork showing the close is fine. We check this before touching any lock; it protects you as the new owner.
  3. Walk the property and count cylinders. Together we walk every exterior opening: front, back, side and garage entry doors, keyed patio handles, gates, sheds and the mailbox. We note brands, keyways and condition, and ask which areas you'd like on one key. That list becomes the written quote, so nothing gets added without your approval.
  4. Re-pin each cylinder. Your new combination comes from a fresh code, not a variation on the seller's key. We cut keys on a code machine to the manufacturer's depth and spacing specifications, keeping neighboring cuts within the allowed limits so the key turns smoothly and doesn't wear early. Kwikset SmartKey cylinders are reset with their own tool instead of loose pins.
  5. Reset codes and test every key. Before we pack up, every door gets a full function test: the key turns smoothly, the deadbolt throws completely into the strike, and the latch catches when the door closes. Electronic locks get new codes and fresh batteries if needed. Anything that didn't pass gets fixed or flagged on the invoice for a follow-up.
  6. Hand over the keys and the record. Before we leave, we count the keys out with you and decide where each one goes. A spare belongs with a person you trust or in a lockable spot indoors, not under a mat or inside a fake rock. If you'll add locks later, hold on to the key code record so new hardware can match from day one.

What affects the cost

  • Lock condition. Vacant and flipped homes bring their own wear. Locks left unused for months can seize, flip crews sometimes paint right over escutcheons and screws, and preservation crews may have drilled cylinders and swapped in whatever was handy. Each of those adds labor or parts. We point them out during the walk-through so the quote reflects the actual hardware.
  • High-security and smart locks. Standard residential cylinders are the quickest. Restricted high-security systems such as Medeco or Mul-T-Lock may need key blanks from an authorized source, or factory service, and can take longer to arrange. Smart lock resets and app pairings add some time per lock. We identify these before quoting so there are no surprises.
  • Scheduling and location. Planned rekeys are easier to schedule and price than emergencies. If you call a few days before closing, we can line up a visit that fits your moving plans and route it efficiently. A same-day request is often possible too, but evening slots before our 11:30 p.m. close fill quickly.

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 Fontana.

What to do before we arrive

  • Ask your agent to collect every key, remote and code from the sellers before closing, and to note how many there are. It won't make rekeying unnecessary, since nobody can account for copies made at a hardware store, but it tells you which locks exist and whether any are high-security.
  • Call the alarm company to change the master and user codes, and ask them to remove the previous owner's contact list. In HOA communities in Fontana, contact management to deactivate the seller's gate remotes or pool fobs and issue yours. These sit outside a locksmith's work but belong on the same checklist.
  • Don't forget sliding doors and windows. Most sliders have no keyed cylinder, and their latches are often worn. Add a secondary lock or a bar in the track, and check that every window latch in the house actually catches. Rekeying won't help an opening that never locks properly in the first place.
  • Ask for one key for the whole house. Fewer keys means fewer copies to track, and it's easier for every family member. If you want certain areas kept separate, like a home office or detached workshop, we can put those on their own key while everything else shares one.

What not to do

  • Tackling a DIY rekey kit on a mix of brands without knowing what you have. Kits are brand-specific, Kwikset SmartKey cylinders need their own tool, and springs lost under a sofa end many weekend projects. A locksmith visit handles every brand at once and leaves each lock tested.
  • Assuming new locks from a store box are unique. Retail locks ship with factory combinations drawn from a limited set, so the same key code turns up in other packages on other shelves. If you install new hardware yourself after buying, having it rekeyed to a fresh combination is what makes those keys truly yours.
  • Ignoring codes and electronic access. A rekeyed deadbolt with the seller's keypad code still active, or a smart lock still linked to their app, leaves the door open to them. The same goes for garage remotes and alarm codes. Reset everything programmable on the same day the keys change.

Frequently asked questions

The house is brand new. Do I still need to rekey?

It's less urgent but still worth checking. Builders often use construction keying so the trades' key stops working after the homeowner key is used, yet that only works if every cylinder was actually switched over. Model homes and spec homes also see plenty of visitors. A quick test or a full rekey removes the uncertainty for a modest cost.

When is the best time to rekey after closing?

On the day you take possession, before movers arrive. If the sellers are renting back, rekey the day they hand over the keys and leave. If you're remodeling first, give contractors a temporary key and rekey when they finish. Calling (951) 903-3193 a few days ahead of closing helps us fit your date into the schedule in Fontana.

Can you rekey on a weekend before our move?

We work every day from 6:30 a.m. to 11:30 p.m., weekends included. We're closed between 11:30 p.m. and 6:30 a.m. Sunday works well for buyers who want the rekey done before the workweek starts, and early weekday mornings are another good option. Book a few days ahead of closing if you can, and we'll fit your visit around movers and escrow timing.

Does rekeying cover the garage door and the keypad codes?

Rekeying covers the keyed locks, including the door between the garage and the house. The big garage door opener is separate: clear its memory with the learn button and reprogram only your remotes and keypad. We do reset keypad deadbolts and smart locks as part of the visit, clearing old codes and the previous owner's app access.

Can every lock be rekeyed?

Most standard residential locks can, including Kwikset, Schlage, Yale and many keypad deadbolts with backup cylinders. Some very inexpensive locks aren't worth the effort, some high-security brands require authorized service or restricted blanks, and certain smart locks have no key cylinder at all. Badly worn or broken locks are better replaced. We'll tell you which is which during the walk-through.

I bought a rental property with tenants living in it. Can I rekey their unit?

Yes, with the tenant's rights in mind. In California, a landlord generally needs to give reasonable written notice before entering, and 24 hours is presumed reasonable. Schedule the rekey for the agreed time, hand the tenant new keys right away and keep the owner's copy somewhere secure. Main entry doors on rental units must also have working deadbolts under Civil Code §1941.3.

How far is Fontana from your base?

Fontana is about 16 miles from our San Bernardino base, roughly 22 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.
