Rekey Locks after Buying a House in San Dimas, Before You Unpack

How this works in San Dimas

Keys are only half of a modern home's access. A keypad deadbolt may still open with the seller's code, or with codes they gave a cleaner years ago. A smart lock such as a Schlage Encode, Kwikset Halo or August may still be linked to the previous owner's app account, which means they could operate it remotely; a factory reset clears that. Garage door openers keep learned remotes and keypad codes until someone erases them at the opener's learn button. We handle the lock side, resetting keypad codes and smart lock pairings, and we'll point out the rest so nothing gets missed. The alarm company needs a call to change master codes, and the HOA handles pool and gate fobs. Expect us to ask for proof that the house is yours. Because your driver's license won't show the new address yet, a photo ID with your closing statement, grant deed or escrow documents works. That check is how we make sure we're helping the buyer, not someone who simply happens to be standing on the porch.

Work included on a typical visit

• Whole-house rekey on possession day. An empty house is the easiest one to rekey. Nothing blocks the slider, the garage isn't stacked with boxes, and every door can swing freely while we test. We work one door at a time, so the house is never left without a working lock, and you can keep meeting the internet installer or the utility crew while we go.
• 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.
• Keypad and smart lock resets. Retrofit smart locks catch a lot of buyers off guard. An August-style unit clamps over the inside thumbturn and a Level Bolt-style unit replaces only the bolt, so the original exterior cylinder stays and still takes the seller's key. Older keypad deadbolts may also need a programming code printed on a label inside the housing. We handle both before leaving.
• Gates, sheds and outbuildings. If your new property includes a detached garage, RV gate, pool equipment enclosure or tool shed, those locks share the same key-history problem. We bring them under your new key, or a second key for areas you want kept separate, such as a workshop you'd rather guests and contractors couldn't open.
• Key control after the move. Keys stamped 'Do Not Duplicate' still get copied at plenty of counters; the stamp is a request, not a control. Real key control comes from a restricted or patented keyway, where blanks are cut only for the registered owner who presents a key card. If tracking every copy matters to you, we can fit those cylinders on your main doors.

How San Dimas shapes the job

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 Via Verde, 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.

Horse properties add tack rooms, feed storage and arena gates to the list, and previous owners may have given keys to farriers, trainers and boarders. When you buy one, rekeying the house is the start; securing tack and equipment is the next step, since saddles and tools are tempting targets. We can key barn areas alike for staff while keeping the residence on its own key.

Foothill homes often have gates, detached garages and side doors facing canyon brush, plus previous owners who left spare keys with neighbors during wildfire evacuations. After buying near Walker House, rekey every exterior lock and think about which neighbor, if any, should hold your new spare. Evacuation season is a good reason to keep one spare with someone you trust who lives close by.

Situations this covers

• 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.
• Think of a family moving into an estate-sale home near Raging Waters Los Angeles, where the previous owner's caregivers, relatives and a home health aide all had keys over the years. Nobody can produce a list. Rekeying every exterior door, plus a reminder to clear the old garage opener codes, gives the new owners a clean starting point before the moving truck arrives.
• 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.
• 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.

From your call to the finished job

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. We verify every buyer before rekeying. A driver's license with your name, matched to the final settlement statement or recorded deed, is ideal. Buying through a trust or LLC? Bring documents showing you're authorized for that entity. It takes a couple of minutes and keeps us from rekeying for the wrong person.
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. We remove each cylinder, push out the old pins, and load a new combination using our key gauge and pinning kit, matched to the fresh key we've cut. Master pins aren't needed in a single-family house, which keeps the locks simpler and harder to manipulate. Then each cylinder goes back exactly as it came out.
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. The visit ends with keys in your hand and a clear record of the work. Keep it with your closing papers. It lists the locks we handled and the keying, which makes later additions, like a new smart deadbolt, easy to match. Then reset the garage remotes and you're done.

How we quote the job

• Number of cylinders. Every keyed cylinder is a separate rekey, so a house with matching deadbolts and knobs on three doors means six cylinders before gates or the mailbox. Adding outbuildings adds cylinders. We price per cylinder plus the visit, which makes it easy to see the effect of including or skipping any lock.
• Mixed brands and keyways. If every lock is the same brand and keyway, keying them alike is simple. When a house mixes Kwikset KW1 and Schlage SC1, the outliers need a compatible cylinder or a new lock to share your key. That adds parts. We'll show you the most economical way to reach one key, or two if you prefer.
• 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.

Advice before you book

• Skip the address tag on your new key ring. A lost ring labeled with a street address is an invitation, and a ring labeled 'front door' tells a finder exactly what it opens. Colored key caps or a simple shape code do the same job for your household without telling a stranger anything useful.
• Schedule the rekey before movers arrive. Once boxes and furniture are inside, you're protecting more behind locks whose key history is unknown, and moving day itself brings helpers through every door. Even a morning appointment on possession day, before the truck shows up, closes that gap.
• 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 San Dimas, 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.
• 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

• 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.
• Rekeying only the front door. The garage entry door, side door and back door are just as likely to be used by someone with an old key, and they're often easier to approach unseen. If you're paying for a visit, cover every exterior cylinder, plus gates and the mailbox if they're keyed.
• 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.

Reaching San Dimas
