Rekey Locks in Glendora: Know When, Then Get It Done
Short answer: The right time to rekey is the day the risk begins, not after something goes missing from the house. Lost keys tied to your address, a move-in with unknown copies floating around, or a rental turnover all qualify. In Glendora, we come to the property, verify that you own or manage it, and hand you new keys that run every rekeyed door.

Five keys for five doors is a habit, not a requirement. When we rekey locks in Glendora, one of the most common requests is to fold the front deadbolt, front knob, back door, garage entry and side gate onto a single key. It works when the cylinders share a keyway, and most builder-grade homes in the area use one brand throughout, or close to it. Where an odd lock won't match, we'll tell you whether a replacement cylinder or a new lockset is the better route. You end up with fewer keys on the ring, fewer chances to grab the wrong one in the dark, and old copies that no longer work anywhere on the property.
Most people don't think about rekeying until an event forces it, and in Glendora the triggers are predictable. Move-in is the biggest: you can't know how many copies of the previous owner's keys exist, from a realtor's lockbox to a dog walker to the painter. A lost key or a stolen purse is next. A roommate or partner moving out is the third. A rental turning over between tenants is the fourth. Rekeying suits all four better than replacement because you keep the hardware you chose and still make every old key useless. It also lets us key the exterior locks alike, so the front door, back door, garage side door and a gate lock open with one key instead of five. Families in the ranch homes around the South Hills tend to ask for exactly that, since kitchen, garage and patio doors are all in daily use. Count your locks before we arrive. People forget the garage side door, the shed, the back gate, the mailbox and any padlocks, and each one is easy to add during the same visit. We check ID and proof of residence or ownership before changing any lock, because rekeying takes away someone's access, and that decision belongs to the person entitled to make it.
Rekey Locks in Glendora: what to expect
Who gets to order a rekey matters as much as when. Homeowners can rekey their own locks whenever they like; we only ask for ID and proof of ownership, such as a deed, closing statement or property tax bill. Renters are a different case. Many leases in Glendora require landlord approval for lock changes and a copy of any new key, so the cleanest route is to ask the manager first and let us coordinate that extra key. Landlords and property managers rekey between tenants as standard practice, and California Civil Code 1941.3 already requires them to provide working deadbolts on main entry doors. Rekeying makes sure those deadbolts answer only to the current tenant. There's also a special case worth knowing: California tenants with a qualifying protective order, or in some situations a police report, can require the landlord to change the locks within 24 hours of asking. A rekey is usually the fastest way to meet that deadline. Executors, trustees and HOA boards each have their own paperwork, and we'll tell you exactly what we need when you call.
Work included on a typical visit
- Lost or stolen key rekeys. A lost key with nothing linking it to your address is low risk. A stolen purse holding your driver's license, or a car taken from the driveway with the house key on the ring, is not. In that second case we move the visit up, rekey locks at every door that key opened, and cut replacements.
- Ex-roommate, partner and family changes. Divorce and separation calls need tact and paperwork. We confirm the person requesting the rekey has the right to do so, which may mean a deed, lease or court order, then re-pin the locks and hand over new keys. If both parties are still on title, settle that first; we don't take sides.
- Keying every door alike. Many Glendora homes collect a different brand at every door after years of piecemeal repairs: a Kwikset knob, a Schlage deadbolt, a no-name lever on the garage entry. We sort them by keyway, rekey what can match, and suggest the fewest replacements needed to get you down to one key.
- Rekeys after contractors, sitters and caregivers. Remodels hand out keys freely: the general contractor, the tile crew, the cabinet installer, maybe a lockbox code everyone on the job knew. When the final punch list is done, rekey locks and close that chapter. We can come the same week the crew leaves, before furniture and electronics move back in.
- Protective order and safety rekeys. If someone you need protection from had a key, call us. California tenants with a qualifying protective order or police report can ask their landlord to change the locks within 24 hours. We work with landlords, managers and tenants to rekey quickly, and we keep the details of the visit private.
What's different about Glendora
Larger homes have more doors and more people with keys: housekeepers, estate managers, pool and landscape crews, sometimes private security. A rekey is a chance to restructure, not just reset. Many owners choose high-security or restricted cylinders on the main entries, keep service doors on a separate key, and limit duplicates through a signed key agreement. We map the plan door by door before anything changes.
Clinics and medical offices hold patient records and controlled supplies, so key turnover matters more than usual. When a staff member leaves, rekey the suite entry, medication room and records storage, and track who carries each key. Restricted keyways stop casual copying. For suites in a managed building near Rubel Castle, we work within the building's master system with the property manager's approval.
Busy households lose keys constantly: on sports fields, in backpacks, at friends' houses. In family neighborhoods across Glendora, a keyed-alike rekey simplifies daily life, since everyone carries one key that opens the front door, back door and garage entry. Pair it with a keypad deadbolt on the door the kids use most, and a lost key stops being a reason to rekey every season.
Common situations
Suppose a family buys a house in the South Hills tracts and the seller's agent hands over three keys, with no way of knowing about the rest. They ask for the front, back and garage side doors to share a single key, plus the gate padlock. We'd check closing papers and ID, rekey the four locks to a new key set, test each, and cut spares. The old keys, wherever they've gone, stop working the moment we finish.
- Picture new buyers handed a ring of seven keys at closing, two of which fit nothing. The house has a Schlage deadbolt, three Kwikset knobs and a no-name lever on the garage entry. They'd rather replace two pieces than three, so we install a Kwikset deadbolt and a matching garage lever, rekey everything to one new key, and cut four copies.
- A typical turnover: a landlord with a fourplex off SR-210 has one unit vacated on the 28th and a new tenant arriving on the 1st, with painters booked in between. We rekey the entry knob, deadbolt and rear door on paint day, label three new keys, and leave an office copy in the manager's lockbox along with a note describing the new keying.
- Picture someone returning from a week away to find the back door forced and a spare key ring missing from a kitchen drawer. After the police report, we repair the split strike area, replace the bent deadbolt, and rekey the front and garage entry locks to match the new deadbolt, so the stolen ring opens nothing on the property.
From your call to the finished job
- Tell us why you're rekeying. On the phone we'll ask how many doors take a key, what brand names appear on the lock faces, and whether you still have a working key. With that, we can quote a realistic figure and load the right pins and blanks before we head to Glendora.
- Confirm who's authorizing the work. Verification is quick when documents are ready. A driver's license showing the address, or ID plus a recent bill or closing paper, covers most homes. We note who authorized the job on our work order and keep that record with the keying details.
- Agree on the keying plan. Next we settle the keying: one key for everything, or separate keys for the house and outbuildings. We check each cylinder's keyway first. If one lock won't match the rest, you choose between a second key and replacing that lock before we begin.
- Re-pin each cylinder. We work cylinder by cylinder at a pinning tray, so nothing small gets lost in the carpet. Kwikset SmartKey locks reset with a tool rather than loose pins; Schlage, Yale and most others are re-pinned by hand. The old keys stop working the moment each lock is finished.
- Test every key in every door. Before we call it done, try the keys yourself. Lock and unlock every door that was rekeyed, including the ones you rarely use. It's far easier to catch a stiff lock while we're still in your driveway than after we've left for a job in San Dimas.
- Hand over keys and a key list. You receive the number of keys you asked for, cut and tested, plus a written note of which doors they operate. We suggest recording who gets each copy. The old keys can go straight in the trash, since they no longer fit any lock on the property.
What affects the cost
- Brands and keyways. When every lock shares one keyway, rekeying to one key is straightforward. Mixed brands change the math: matching a Schlage deadbolt to Kwikset knobs means replacing a lock or cylinder, which adds parts. We'll show you which locks match and price the options side by side.
- Keying plan and number of keys. A plain one-key-for-everything plan is the simplest. Splitting the property into zones, such as the house on one key and a rented casita on another, adds cutting and planning. Each extra key adds a little, and restricted or high-security blanks cost more than standard ones.
- Lock condition. A clean, smooth cylinder rekeys quickly. One packed with dust, gummed with oil or worn from decades of use takes longer, may need new springs, and occasionally isn't worth saving. Inland heat and wind-blown grit age exterior locks faster than most people expect.

Practical tips before you call
- After any rekey tied to lost or stolen keys, clear your garage opener's remote memory. On most LiftMaster and Chamberlain openers, holding the learn button on the motor unit until its light goes out erases every paired remote and keypad. Then re-pair the remotes you still have.
- Test the new keys in every lock before the technician leaves, including doors you rarely use. A stiff side-door deadbolt is much easier to sort out in your driveway than on a hurried morning when you finally need that door to open.
- Write down who gets each new key, with the date. A short note on your phone turns a future question about who still has a copy into a quick check rather than another rekey. Landlords should keep the same list in each unit's file.
- Lost keys without ID? Think about where they disappeared. Keys dropped on a hiking trail carry less risk than keys taken from a gym locker along with a wallet. Rekeying costs little compared with years of wondering, but the second case shouldn't wait a single night.
What not to do
- Buying a DIY rekey kit for a house with mixed brands. Kits fit one brand and one keyway, and SmartKey resets can jam if the key comes out at the wrong moment. A half-finished rekey often leaves a door that no key will open at all.
- Changing the smart lock code and forgetting the key cylinder. A keypad reset does nothing to the physical keys a former roommate or tenant still carries. Rekey the backup cylinder too, or the old key quietly keeps working every time they stop by.
- Trusting that you received every key. Sellers hand over whatever they find in a drawer, not what they gave a cleaner six years ago. Former tenants return one copy and forget the spare in their car. The count you're handed is rarely the count that exists.

Frequently asked questions
How long does it take to rekey a whole house?
A typical house with four to six cylinders is finished in a single visit, usually an hour or two once we're on site, though dirty or worn locks take longer. Adding gates, padlocks or keyed-alike lock replacements extends the job. We'll give you a realistic estimate of time on site when you call (951) 903-3193 and describe your doors.
Can I rekey my apartment as a renter?
Usually only with your landlord's permission, and many leases require you to give them a copy of the new key. Some complexes run master key systems that a tenant rekey would break. Ask management first; if they approve outside work, we'll verify your lease and the approval, rekey the unit, and help get a key to the office.
My roommate gave back their key. Should I still rekey?
Usually, yes. A returned key doesn't tell you whether copies were made, lent to a friend or left in a car. Rekeying the shared doors is the only way to be sure the old key, and every copy of it, stops working. If you rent, get your landlord's approval first and we'll provide a copy of the new key for them.
Should I rekey after a break-in?
Yes, if keys, a garage remote or anything with your address was taken, or if you simply can't be sure. If the door was forced, the lock or frame may be damaged and need repair or replacement rather than a rekey. We assess each door, fix what's broken, and make sure every exterior lock runs on a key the intruder never had.
Can you rekey my locks today?
Often, depending on the schedule and your distance from our San Bernardino base. Urgent rekeys after stolen keys or safety concerns get priority when we can manage it. We work every day, 6:30 a.m. to 11:30 p.m. Call (951) 903-3193 for an honest ETA to Glendora.
What do I need to show before you rekey?
Photo ID plus something that ties you to the property: a deed, closing statement, lease, recent utility bill or property management agreement. Landlords and managers show ownership or authority, while executors bring letters testamentary or trust documents. We won't rekey a lock for anyone who can't show they have the right to, and that rule protects you too.
How far is Glendora from your base?
Glendora is about 35 miles from our San Bernardino base, roughly 41 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.
