Rekey Locks after Buying a House in Pomona

What to know first in Pomona

A thorough rekey after a home purchase starts with a walk-through. We count every keyed cylinder: front deadbolt and knob or handleset, garage entry door, back and side doors, keyed patio handles, gates, sheds and the mailbox. Then we look at brands and keyways. Many resale homes in Pomona have a mix, say Kwikset on the front and Schlage on the garage door, and those two use different keyways (KW1 and SC1), so they can't share one key as they stand. We can swap the odd cylinder or replace that lock so one key runs the whole house. Kwikset SmartKey locks are rekeyable too; we set them to your new key so the old one no longer turns them. High-security cylinders such as Medeco or Mul-T-Lock may need restricted blanks or authorized service, and we'll tell you if yours fall into that group. Last, we flag hardware that isn't worth rekeying: worn latches, wobbly deadbolts, a bargain lock on the door from the garage. You decide what gets rekeyed and what gets replaced.

How we can help in Pomona

• Whole-house rekey on possession day. Possession day is when this service makes the most sense. We arrive with pins, key blanks and a code machine, work door by door, and test every new key in every lock before leaving. If a cylinder turns out to be seized or broken, we stop and show you rather than forcing it.
• Lock condition check and upgrades. If you want the rekey to do double duty, we can load security pins, such as spool or serrated top pins, into cylinders that accept them, which makes picking and bumping much harder. Swapping short strike screws for three-inch screws that bite into the stud is another quick improvement. Each upgrade is priced separately, so you can pick and choose.
• 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.
• Security screen doors and iron gates. Screen doors keyed on both sides deserve a closer look. A double-cylinder lock needs a key to get out, and building codes expect the main exit to open from inside without one. We can key it to your house key, switch it to a single-cylinder version with an inside thumbturn, or talk through what suits a door with glass nearby.
• When the seller's keys don't fit. It's surprisingly common to close escrow holding a ring that opens the front door and nothing else. After we confirm you own the home, we open the remaining locks without damage whenever the lock allows it, using picks or decoding tools, then rekey them to your new key so the missing originals no longer matter.

How Pomona shapes the job

Older homes in Pomona 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.

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 Pomona, 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.

Where rental housing is dense, a purchase is often a condo carved from a former apartment building or a small multi-unit property with tenants in place. Rekey your own unit right away. For occupied units, California generally expects reasonable written notice before entry, with 24 hours presumed reasonable, and the tenant needs new keys the same day. Civil Code §1941.3 also requires working deadbolts on the main entry doors of rental units.

Example situations

• For example, a couple closes on a 1960s single-story home in Spadra, and the seller's agent hands over three different keys plus a garage remote. During the walk-through we'd find a Kwikset front deadbolt, a Schlage knob on the garage entry door and a padlock on the side gate. A typical plan: re-pin what matches, swap the odd cylinder, and leave them with one key for every door.
• Suppose escrow closes and the ring from the agent opens the front deadbolt but not the side door or the door from the garage. Maybe a seller swapped those locks years ago and kept the keys in a drawer that left with them. After checking your ID and closing papers, a locksmith would open the two odd locks, read their pins, and bring all three doors onto one new key.
• Here's a common one on larger lots: a ranch-style property with a detached garage, a tack room or workshop, and a long driveway gate. The seller leaves a coffee can full of unlabeled keys. We'd sort which keys fit which locks, rekey the house to one key, put the outbuildings on a second, and recommend replacing padlocks that have rusted beyond saving.
• Consider a buyer who purchases a duplex near Pomona Valley Hospital Medical Center, moves into one side and inherits a tenant in the other. Their own unit can be rekeyed the day they take possession. The tenant's unit is different: a typical plan is giving proper written notice, rekeying at the agreed time, handing the tenant new keys on the spot, and confirming the main door has a working deadbolt.

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. 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. 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. With the pins done, we clear keypad codes, factory-reset smart locks and pair them to your phone. Then we test every new key in every lock, from inside and outside, with the door open and closed. A key that turns stiffly gets corrected now, not discovered when you're standing on the porch with groceries.
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.

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.
• 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.

Advice before you book

• Walk the perimeter looking for hidden keys: fake rocks, magnetic key cases under eaves or meter boxes, keys taped inside an electrical panel door, and combination lockboxes that contractors left on hose bibs or fences. Rekeying makes those keys useless, but a lockbox still holds whatever someone puts in it next. Remove everything you find.
• 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.
• Ask the sellers to remove the property from their app accounts before closing: Wi-Fi garage controllers, video doorbells, smart thermostats and connected locks. If they can't or won't, factory reset each device after you take possession. A garage controller still tied to someone else's phone can raise the big door no matter which keys you hold.

What not to do

• Waiting until after moving in. Once your belongings are inside and life gets busy, rekeying slides down the list for weeks or months. Meanwhile, every old key still works. Book it for possession day; it's a short visit compared with everything else you're juggling that week.
• 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 the sellers handed over every key. They gave you the keys they could find. Copies made years ago for a babysitter, a contractor or a neighbor are almost never accounted for, and lockbox access during the sale added more people. Rekeying is the only way to know the count is zero.
