House Rekey in Monrovia: Every Door Accounted For
Short answer: A house rekey changes the pins in every keyed lock on your home so old keys stop working, while the hardware stays on the doors. In Monrovia, Julian's Locksmith walks the house with you, counts each cylinder from the front door to the side gate, re-pins them to one new key or to separate keys where you want them, and quotes before starting. Call (951) 903-3193.

Keys are only one way into a house. Garage door remotes, the keypad by the garage, smart lock codes, alarm codes, a hidden spare under a fake rock and a realtor's lockbox can all outlast a rekey. That's why our house rekey visits in Monrovia end with a short checklist: we re-pin every keyed cylinder, then help you clear the garage opener's memory, change keypad and smart lock codes, and retire any hidden spare. When we leave, the ways into your house should match the people living in it, and nothing more.
What to know first in Monrovia
During a house rekey, every door gets one of three decisions: rekey it, replace it, or key it separately. Rekeying is the default for sound hardware, because the lock already fits the door and costs nothing extra to keep. Replacement makes sense when a lock wobbles on the door, the finish has worn through, the key sticks even when it's cut fresh, a back door has no deadbolt at all, or a cheap builder knob guards a garage entry that deserves better. Separate keying fits a rented casita, a room with its own entrance, or a workshop with expensive tools. We'll make a recommendation for each opening and price them line by line, and you choose. A house in Monrovia commonly ends up mostly rekeyed, with one or two locks replaced and keyed to match, and a deadbolt added somewhere it was missing. Nothing gets swapped without your approval and a price for that specific lock.
How we can help in Monrovia
- Security screen and wrought-iron doors. Security screen doors double the cylinders on an entry: one on the screen door, one or two on the door behind it. A house rekey that skips the screen door leaves an old key working on the first barrier. We rekey or replace that lock and make sure the latch still catches against the frame.
- Side gates and yard padlocks. A side-gate padlock still on an old key gives anyone holding that key quiet access to your backyard and back door. During a house rekey we either re-pin the padlock to your new key, swap it for a rekeyable model, or suggest a combination padlock if neighbors or gardeners need gate access.
- Casitas, ADUs and rented rooms. Rooms rented with their own exterior entrance, a converted garage studio, or a home office with client access can each get a separate key during the house rekey. Rekeying a tenant's unit requires the right notice and paperwork, so plan timing around the lease and any move-out date.
- Older-house and mortise locks. Many mid-century houses in Monrovia still run the knobs they were built with. Older Schlage knobs, for example, rekey well once the grime is cleaned out. Where an old lock's parts are no longer available or its keyway can't match the rest of the house, we'll show you a replacement that suits the door's style.
- Keypads, smart locks and garage codes. Electronic locks bring their own checks during a house rekey: battery condition, a backup key that actually works, and the admin login. If a smart lock uses a proprietary backup cylinder that can't be re-pinned, we'll explain the choices, from a factory replacement cylinder to relying on codes and storing the old key securely.
Local factors in Monrovia
In a family neighborhood the problem is volume. Teenagers, grandparents, babysitters, carpool parents and dog walkers all pick up a key over the years, and kids lose them. A house rekey in Monrovia is the natural time to cut a short list: one key per adult and driver, a labeled spare, and codes for everyone else. Kids' keys go on distinctive rings with no address tag. Evening appointments run until 11:30 p.m. every day.
Long commutes leave the house empty from early morning, and a rekey can't happen while you're stuck on the freeway. We start at 6:30 a.m. every day and run until 11:30 p.m., so an early or evening appointment fits around the drive home. If you can't be there all day, a spouse or trusted adult can show ID at the start of the visit, walk the doors with us and approve the quote.
Hillside houses often have several levels of entry: a street-level garage, a lower patio door, a deck stair and a side path with a gate. Each is a keyed opening to count during a house rekey in Monrovia. Santa Ana winds blow grit into cylinders and slam doors on loose strikes, so we clean the locks we rekey and check that latches catch. Consider leaving a spare with someone who can reach the house if you can't.
Common situations
- For example, owners who rented their house out for six years are moving back in. Several sets of tenants, a property manager and maintenance vendors all had keys. We rekey every exterior lock, the side gate padlock and the garage entry door, help them reset the garage opener, and suggest swapping the worn back door deadbolt for a new one keyed to match.
- Picture a 2006 two-story off Canyon Boulevard with builder-grade Kwikset SmartKey on every door. The previous owners left two keys and a garage keypad still set to their code. With a working key, each SmartKey cylinder resets quickly, so the house rekey covers the front, garage entry, garage side door and back door in one short visit, followed by a keypad code change.
- For example, an executor handling a late parent's house books a rekey before the cleanout crew starts. She brings ID and the court's letters showing her authority. Several relatives, a caregiver and a neighbor had keys over the years. We rekey every exterior lock, cut keys for the executor and the cleanout company, and note which doors share a key for the eventual buyer.
- Picture a 1930s Spanish-style house in South Monrovia with its original mortise lock on the arched front door. The cylinder on the outside is threaded into the lock body and can be re-pinned, so the door keeps its character. The interior skeleton-key locks don't matter for security, and the back door gets a modern deadbolt keyed to the front cylinder.
How the visit works
- Walk your house before you call. Pull out every key you own and try each one in each lock during your walk. You'll learn which doors share a key already, which locks have no working key, and whether a mystery key opens something you forgot. Share that with us when you call (951) 903-3193.
- Gather proof the house is yours. Verification is quick when the papers are ready. Keep your ID and one document tying you to the address near the front door. If the house is newly purchased and your license still shows an old address, escrow or closing documents with your name on them do the job.
- Walk-through and label every door. When we arrive, we walk the house with you and confirm every opening on the list. This is where the forgotten locks surface: a screen door, a padlock behind a trash can, a door from the garage into a side yard. Each one gets a label on the work order and a line on the quote.
- Settle the key plan. Think beyond this week. If a family member may move into the casita, or you plan to rent a room later, keying it separately now saves a future rekey. We'll explain the trade-offs and cut a key count that fits the people actually living in the house.
- Rekey door by door and test. We pull one cylinder at a time, re-pin it to the new combination and put it straight back, so the house is never left with an open door. Each lock is tested with the new key from inside and outside, with the door shut, and the old key is tried so you can watch it fail.
- Close the routes keys don't cover. A house rekey changes cylinders, not codes. Before we leave, we help you clear the garage opener's memory and re-pair the remotes you're keeping, change the garage keypad code, remove old smart lock users, and retire any hidden spare. Then the new keys and a short key list are yours.
Pricing factors
- Separate key zones. Zones change the key count more than the pinning work. A main house key plus a separate casita key means two sets of keys to cut and track. If an owner needs a key that opens both, ask about it; on some hardware that requires master pins, which takes more planning.
- Extras around the property. The extras are often where old keys linger longest. A screen door on a separate key, a padlock nobody remembers buying, a shed lock from the previous owner. Each one is priced individually, so you can include what matters and skip what you plan to replace yourself.
- Missing keys and stuck cylinders. If the sellers, a former tenant or a relative left you no key for one door, tell us when you call. It changes the approach for that lock and sometimes the parts we bring. Most can be opened and rekeyed without damage; a few are better replaced to match the rest of the house.
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 Monrovia.
Practical tips before you call
- If a lockbox was used during a sale, remodel or rental, take it down or change its code once the work is done. Lockbox codes travel among agents, contractors and cleaners, and a rekey doesn't help if a new key ends up sitting in the same old lockbox.
- Decide what to do with the casita or rented room before the visit. Keying it separately protects a tenant's privacy and your own; keying it to the house is simpler if family uses it. Making the call ahead of time keeps the walk-through short and the quote accurate.
- Leave address tags off key rings, especially kids' keys. A key with a tag or a school ID showing your street is a key that leads straight back to your house. Use a colored key cap or a distinctive ring so family members can tell the house key from the rest.
- Clear your garage door opener's memory after any rekey prompted by keys that walked away. On most openers you hold the Learn button on the motor unit until its light goes out, then re-pair the remotes you're keeping. Change the outdoor keypad code at the same time.
Mistakes to avoid
- Buying matching locks for one door and expecting the house key to fit. Different brands use different keyways, so a new Schlage lever won't take your Kwikset key. Tell your locksmith before buying, or let us supply hardware keyed to the rest of the house.
- Leaving the screen doors and gate padlocks on old keys because they're "just the outer layer." They still control access to the doors behind them and the backyard. If a former key holder can open the screen or the gate, the house rekey left a gap.
- Rekeying only the front door. Anyone holding an old key will try the back door, the garage side door or the garage entry next. A house rekey only works when every exterior keyed lock moves to the new key, including the ones that rarely get used.

Frequently asked questions
When can you do my house rekey in Monrovia?
We schedule Monrovia house rekeys every day from 6:30 a.m. to 11:30 p.m. Weekends are included. Call (951) 903-3193 and we'll give you an honest arrival window based on our schedule and the drive. If you feel unsafe and we're closed, call 911 first; the rekey can follow on the next day we're open.
What does a house rekey include?
A house rekey re-pins every keyed cylinder on your home to a new key, so old keys stop working while the hardware stays on the doors. We count the front deadbolt and handleset, the garage entry and garage side doors, back and patio doors, security screens, gate padlocks and any outbuildings, then rekey the ones you choose. We quote by the cylinder count, cut the new keys, test every lock, and go over codes and remotes before we leave.
Can I rekey a house I rent?
You'll need the owner's written permission, because a lease usually bars tenants from altering locks without consent. Many owners agree, especially if they receive a key. California also limits when a landlord may enter and requires notice, so a rekey is best treated as an agreement between tenant and owner, not a unilateral change. Bring the owner's written okay when we arrive, along with your ID and a lease showing the address.
How often should I rekey my house?
There's no calendar interval. Rekey when the list of people who might hold a key stops matching the people you trust: a move-in, a lost key, a breakup, a roommate leaving, the end of a remodel or a tenancy. Houses that host guests or employ regular help may rekey more often, or move to codes. If you can't say who holds copies, that's reason enough, even years after your last rekey.
Does a house rekey cover the garage opener and keypad?
No. Rekeying changes keyed cylinders only. Your opener still answers every remote ever paired with it, and the outdoor keypad keeps its old code, until you reset them. On most openers, holding the Learn button on the motor unit until its light goes out erases the remotes, and then you re-pair the ones you're keeping. We walk you through that and the keypad code at the end of the visit.
How many keys should I have cut?
One per adult and driver in the household, plus a spare kept somewhere secure that isn't outside the house. If a casita or workshop has its own key, count those separately. Resist cutting a handful for helpers; a keypad or lockbox code is easier to change than a key is to collect. We cut keys to code during the visit, test each one in every lock it should open, and note who received which.
How far is Monrovia from your base?
Monrovia is about 44 miles from our San Bernardino base, roughly 48 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.
