Should you rekey or replace when you change locks in Monterey Park?

Most people who call us about a lock change aren't attached to a method. They want the keys that are out in the world to stop working: the previous owner's, an ex-roommate's, a contractor's, the spare nobody can account for. There are two ways to get there, and the right one depends on the hardware on your door, not on which option sounds more thorough.

Rekeying keeps your existing lock bodies and changes the internal pin arrangement so the old keys no longer turn them. Replacing swaps the hardware for new locks. On the basic security question, both end the same way: the old keys are dead. The difference is what else you want from the door. Our job is to look at what you actually have and tell you honestly which one fits. If you want the full detail on either path, we cover them on our pages for lock rekeying and lock replacement.

What does it mean to change door locks?

Change locks is an everyday phrase that covers several different jobs, and it helps to know which one you're really asking for. When you call, you don't need to know the right term. Describe the door and what's worrying you, and we'll sort it out. But here is how we think about it:

  • Rekey: the same hardware gets a new key. When the locks are sound and from a reputable maker, this is usually the more economical route.
  • Replace: new knobs, levers, handlesets, or deadbolts go on the door. This makes sense when the old hardware is worn, damaged, loose, or simply not something you want to keep.
  • Upgrade: you move to a stronger deadbolt, a different style, or an electronic lock because you want more than just new keys.
  • Key everything the same: several doors get set up so a single key opens them all, which is often the real goal for a household that's tired of a heavy key ring.

How do you change locks after buying a house?

If you've just bought a place, changing the locks is one of the first things worth doing, ideally before your first night there. You have no way of knowing how many copies of the old keys exist. Previous owners, relatives, a cleaner, a contractor, a neighbor who watered the plants: any of them may still have one. A lock change fixes that in a single visit, and it costs far less than finding out the hard way. If you're searching for a locksmith for a new house or a locksmith after moving, this is the job you're looking for.

Think through every door that has a keyed lock, not just the front one. People often rekey the front door and forget the back slider, the side door by the garage, or a detached garage. Do the deadbolt and the knob or handleset together so one key works both.

If you closed escrow and the keys you were handed don't work, or you're standing outside without them at all, that starts as a house lockout call. We can get you in and change the locks during the same visit, so you don't have to schedule twice.

  • Front door deadbolt and handleset or knob
  • Back door, patio door, and any side entry
  • Door between the garage and the house
  • Detached garage and side garage doors
  • Gate locks, shed locks, and mailbox locks that came with the property

How a lock change works, step by step

Here is what happens when you call us about changing the locks at your Monterey Park home or rental. Nothing about it is complicated, and nothing is done before you've agreed to it.

  1. You call (213) 577-1366. A person answers at any hour. Tell us how many doors, what kind of locks you think you have, whether you're locked out, and whether you're the owner or a tenant.
  2. We tell you what we can from your description, what the job is likely to involve, and when a technician can reach you.
  3. A technician comes to you in one of our mobile locksmith vans, stocked with rekey kits and commonly needed hardware, so most jobs are finished on the spot.
  4. We inspect every lock: brand, condition, how smoothly it turns, and whether the latch and strike plate line up with the door. A lock that sticks or drags often has a door problem rather than a lock problem, and we'll show you what we find.
  5. We recommend rekey or replace, door by door, explain why, and give you the cost before any work starts. You decide.
  6. We do the work, then test each new key several times, with the door open and closed, so you don't discover a stiff lock later.
  7. We hand over the keys and talk through spares. If you need extra copies, our key duplication service covers that, and we suggest cutting copies from the new key rather than the old one.

What affects the cost of changing locks in Monterey Park?

We don't post flat numbers here, because a lock change for a one-door condo and a lock change for a full hillside house are different jobs. What we can do is tell you exactly what moves the cost, so there are no surprises when we give you a quote.

Whatever the job, we tell you the cost before we start. If a quote ever sounds vague, ask for it to be broken down by door and by hardware.

  • Number of locks: every cylinder takes labor, so a whole house costs more than a single door.
  • Rekey versus replace: rekeying typically costs less than new hardware, as long as the existing locks are worth keeping.
  • Hardware grade and finish: a basic knob, a heavier-duty deadbolt, and a designer handleset sit in very different places.
  • Keying choices: setting several doors to one key takes planning, and the cost reflects that.
  • Door and frame condition: a misaligned strike or a loose latch may need adjusting before a new lock will work properly.
  • Time of day: after-hours and holiday calls involve pulling a technician out of normal scheduling, and the cost can reflect that.
  • Travel: Monterey Park is about 19 miles from our Westwood storefront, and distance is part of any mobile visit.

How do you decide between rekeying and replacing?

We don't push one answer. Here is how we usually sort it out when we're standing at the door with you. The honest reality is that plenty of jobs go either way, and your preference counts.

  • Rekey when the locks are in good shape, turn smoothly, and you like how they look. You get the security reset without paying for hardware you don't need.
  • Replace when a lock is loose, worn, rusted, damaged, or visibly dated, or when a previous break-in attempt left marks on the cylinder.
  • Replace when you want a different feature: a stronger deadbolt, a keypad, or a smart lock. Our pages on deadbolt installation and smart lock installation explain those options.
  • Replace when the existing hardware is a cheap set that wasn't built to last. We won't rekey something that we expect to fail soon, because that just means a second visit.
  • Rekey when a mismatched set of locks from different makers can be brought onto one key. This is common in homes that have been repaired piecemeal over the years.

Changing locks across Monterey Park: hillsides, flats, and condos

Monterey Park isn't one kind of housing, and what we see at the door changes by neighborhood. In the southern flats toward Montebello, there are prewar bungalows, and if the hardware on those is decades old, it's worth a close look before deciding to keep it. On the hillside streets, including Monterey Highlands in the northeast and the northern hillsides near Alhambra, postwar ranch homes are common, and those often come with long driveways and detached garages. A hillside rekey in the Monterey Highlands area usually means more than the front door: the garage, side entries, and any gates all need to be on the same plan.

Condos and townhomes along the Atlantic Boulevard and Garvey Avenue corridors work differently. Those complexes lean on shared-entry and mailbox hardware, and your own unit door is only part of the picture. If you're a new owner there, change your unit's locks first, then find out from your association what controls the shared entry and mailbox. A condo lockout near Atlantic Times Square is a common reason people call us, and once we're in, changing the locks is a natural next step. In older apartment buildings on the southern flats, tenants and landlords sometimes need mailbox lock replacement at the same time as a unit rekey.

Sun-exposed hillside doors weather faster than doors in the flats, and Monterey Park's summers are warmer than the coast. The effect on locks is modest, but a faded or warped door sometimes shows up when we're checking how a latch lines up. We'll tell you if it's worth addressing. We cover both ZIP codes in the city, 91754 and 91755, as well as the areas around East Los Angeles College, Sequoia Park, and the Garfield Avenue corridor.

Why call Wilshire Lock & Key to change your locks?

We've been in business since 1987, and we run a real storefront at 10740 Wilshire Blvd in Westwood alongside our mobile service vans. We serve 140 cities across Los Angeles and Ventura counties, and Monterey Park is one of them. When you call, you're reaching one company: no call center farming your job out to whoever's closest, no middleman taking a cut. David, the owner and lead technician, oversees how we work, and that includes how we explain options and what we recommend.

One more thing worth knowing. California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith you're considering, us included, to show you theirs before work begins. It's a reasonable request, and a good company won't mind it.

What to have ready before you call

A little preparation makes the visit faster and the quote more accurate. None of it is required, and we'll work with whatever you know.

  • How many doors need new locks, and which ones.
  • Whether any of your locks still work with a key you have.
  • Photos of the locks, if you can send them. They help us bring the right hardware.
  • Whether you own or rent. Tenants should check their lease and talk to the landlord first.
  • For condos, whether your association controls the hardware on the unit door or only on shared entries.
  • Something that shows you live at the address, since we'll want to confirm you're entitled to have the work done.

Frequently asked questions

Should I change the locks after buying a house in Monterey Park?

Yes, we recommend it. You can't know how many copies of the old keys are out there. Rekeying or replacing the locks before you move in makes sure the only keys that work are ones you hold.

Is rekeying as secure as replacing the locks?

For the question of old keys, yes. After a rekey, the previous keys no longer work. Replacement makes more sense when the hardware is worn or damaged, or when you want a stronger or different type of lock.

Can you change my locks if I'm locked out?

Yes. We get you inside first, then change the locks during the same visit if you'd like. That saves you a second appointment, especially after a move when you may not have working keys yet.

Do you change locks at night and on weekends?

Yes. Our phone is answered 24 hours a day, every day of the year, at (213) 577-1366. After-hours work can affect the cost, and we'll explain how before we begin.

Can one key open every door in my home?

Usually, yes. We can set the front, back, side, and garage locks to one key when the hardware allows it. Some locks can't be changed this way, and we'll tell you if that's the case.

How long does a lock change take?

It depends on how many doors there are and whether you're rekeying or replacing. A single-door rekey is generally quick. A whole house with replacements takes longer. We'll give you a realistic idea once we hear about the job.

Can I change the locks in my condo or apartment?

If you own the unit, you can usually change your own door locks, but check with your association about shared-entry hardware. If you rent, check your lease and talk to your landlord first.

Do I need to be home while you change the locks?

Someone with authority over the property should be there, because we'll want to confirm you're entitled to the work, test the keys with you, and hand them over directly.

Do you serve both Monterey Park ZIP codes?

Yes. We work throughout the city, including 91754 and 91755, and the hillside and flatland neighborhoods alike. Call (213) 577-1366 and tell us where you are.
