Rekey Locks after Buying a House: What San Bernardino Buyers Should Cover

What to know first in San Bernardino

A purchased house comes with a key history you can't see. Over the years a seller may have handed copies to a housekeeper, a gardener, a pool tech, a pet sitter, grown kids who moved out long ago, a neighbor for vacations and the contractor who redid the bathroom. During the sale, a listing agent's lockbox held a key that every showing agent could reach, and inspectors, appraisers and stagers came and went. Foreclosures and flips add another layer: preservation crews and investors often key many properties to one shared code, so a key to your house may open others and the reverse. New construction isn't automatically clean either. Builders commonly use construction keying, designed so the trades' key stops working once the homeowner key is first used, but it's worth confirming that actually happened on every lock. Rekeying settles all of it at once. New pins, new keys, and the only copies in existence are the ones you're holding in your hand.

How we can help in San Bernardino

• Keying the whole house alike. Kwikset's SmartKey cylinders and its older pinned cylinders both take the same KW1 key blank, so a house with a mix of the two can still share one key. Schlage's standard five-pin SC1 locks behave the same way among themselves. The real obstacle is a lone off-brand or import lock, which we usually replace rather than chase scarce parts for.
• Garage entry and side door locks. Side doors, laundry-room doors and the garage-to-house door often carry the cheapest locks on the property. We rekey them to match your new key, check that the latch catches properly and that the strike plate is anchored. If a lock is too worn to trust, we'll quote a replacement rather than rekeying a failing part.
• Keypad and smart lock resets. Codes travel even further than keys. We wipe every stored code from keypad deadbolts, remove the previous owner's app pairing through a factory reset, and help you set new master and user codes. Then we rekey the override cylinder, which most people forget a smart lock even has.
• Gates, sheds and outbuildings. Pool gates add a safety wrinkle. They need to keep closing and latching on their own, and a stiff keyed latch or a padlock hung through the hasp can quietly defeat that. When we bring a pool gate onto your new key, we check that it still self-closes and self-latches, and suggest keyed latch hardware that preserves both functions.
• Lock condition check and upgrades. While each cylinder is out, we look at what most buyers can't see: worn pins, loose deadbolt screws, short strike screws, sticky latches and frames that don't line up. You get a straight answer on which locks are fine to rekey and which are worth replacing or upgrading, with a quote for each.

What's different about San Bernardino

Older homes in San Bernardino often carry decades of key history: original knob locks, deadbolts added by a later owner, maybe a rim lock on a back door. Vintage cylinders can be stiff or corroded, and some original hardware isn't worth re-pinning. During a post-purchase rekey, we'll tell you which locks deserve new pins, which deserve retirement, and whether those older doors and frames will hold a modern deadbolt properly.

Long commutes shape how you rekey. Many buyers in San Bernardino leave before dawn and get home after dark, so the house sits empty most of the day. We start at 6:30 a.m. every day and work until 11:30 p.m. That makes a before-work or evening rekey realistic. Since the garage entry is often your everyday front door, that lock gets extra attention, and a keypad deadbolt can spare you a lockout at five in the morning.

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 San Bernardino, 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.

Example situations

• 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.
• Consider a bank-owned home off SR-210 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.
• 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.
• Suppose you buy a townhome in an HOA community. Your unit's front door and patio gate are yours to rekey, but the pool gate, mailbox units and common doors usually belong to the association. We'd rekey your unit, change your mailbox compartment lock if the HOA allows it, and point you to the management office for pool and gate fobs.

From your call to the finished job

1. Book around your possession date. Call (951) 903-3193 as soon as you know when you'll get the keys. Tell us the closing date, whether the sellers are renting back, and roughly how many exterior doors the house has. We'll schedule the rekey for possession day or the first visit after, before your movers if possible.
2. Bring proof of ownership. If someone else will meet us, such as a spouse who isn't on title, a relative or a property manager for an out-of-area buyer, they need the owner's written authorization plus copies of the ownership documents. We may also call the owner to confirm. It's a little extra effort, and it's the same check we'd want for our own homes.
3. Walk the property and count cylinders. Before quoting, we inventory the house. Each keyed cylinder gets checked for brand, keyway, wear and whether it can join a keyed-alike set. We also note keypads, smart locks and any high-security cylinders. You see the full list and price, and you decide what's rekeyed, replaced or left for later.
4. Re-pin each cylinder. This is the hands-on part. Each lock comes apart, the old bottom pins come out, new pins go in to match your new key, and the springs and top pins are checked for wear. Worn springs or corroded pins get replaced rather than reused, especially on doors that bake in afternoon sun.
5. Reset codes and test every key. Then it's your turn. You operate each lock yourself with the new key, enter your keypad codes, and see how the smart lock behaves from the app and from the door. We show you where the batteries go, what the low-battery warning looks like, and where the backup key works, so nothing surprises you later.
6. Hand over the keys and the record. You receive the number of keys you asked for and a work record showing which locks were rekeyed and which combination they share, so future copies match. We'll remind you about the garage opener, alarm company and HOA fobs, the remaining items on a new homeowner's access checklist.

Pricing factors

• 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.
• Number and type of new keys. Cutting extra copies while we're already there is efficient, since our code machine is set to your combination. Standard keys can be duplicated later at many counters; restricted keys come back through us. Colored key caps or a tag for the workshop key cost little and make a shared ring easy to sort without labeling it with your address.
• Scheduling and location. Bundling saves a return trip. If you plan to add a deadbolt to the garage entry, install a smart lock or replace a failing patio handle, doing it during the rekey means one visit instead of two, and travel is part of every quote. Splitting the work across separate appointments is fine too, but each trip adds to the total.

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 San Bernardino.

What not to do

• Hiding a spare outside the same week you rekey. A fake rock or a key on top of the door trim is the first place anyone looks, and it hands a stranger the very access you just paid to remove. Give a spare to someone you trust, or use a keypad code you can delete.
• Replacing perfectly good locks when rekeying would do. If the hardware works smoothly and you like how it looks, new pins and keys solve the access problem for much less. Replacement makes sense for worn, damaged, low-grade or mismatched locks, or when you want a smart lock upgrade.
• 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.

Advice before you book

• 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.
• If you plan a remodel, give contractors a temporary key and plan to rekey once they're finished, or install a keypad lock whose code you can delete. Rekeying twice costs less than wondering how many copies a crew made, and good contractors won't be offended by it.
• 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.
• 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.
