Drilling a clean bore for a new lockset in a wooden door

What does new lock installation include?

Lock installation means fitting a lock that is not on the door yet, or fitting a different kind of lock than the one that is. A new deadbolt on a door that only had a knob, a lever set for a parent who can no longer turn a round knob, a mortise lock on a storefront, a full set of locks for a freshly hung door: these are all installation jobs. The work is more than screwing hardware into a door. The door has to be prepared, the bore holes sized correctly, the latch and strike lined up, and the lock tested until it throws and retracts without any pushing, lifting or slamming.

That last part is where most do-it-yourself installs go wrong. A lock that sits a few millimeters out of line will work fine in the morning and bind in the afternoon, and a deadbolt that only just reaches into its strike is not adding much security. We have been installing door locks since 1987, and the method has not changed much: measure first, cut clean, set the hardware square, and check the result with the door open, closed, and under the kind of seasonal swelling that wood doors go through in this part of Los Angeles County.

Which lock should go on which door?

Before we pick up a drill, we ask what the door is, who uses it every day, and what you want the lock to do. The answers decide the hardware. This is how we usually sort it out:

  • Front door lock installation: normally a deadbolt paired with a knob or lever set, or a matched combination. The front door is used the most, so smooth operation matters as much as strength. If all you need is the deadbolt half, our page on deadbolt installation in La Puente goes into it in detail.
  • Security lock installation: a deadbolt with a solid bolt, a reinforced strike plate, and long screws that bite into the framing behind the jamb, not just the thin trim. Cylinders that resist picking and drilling add another layer, and we cover those separately under high-security locks.
  • Lever lock installation: lever handles are easier on arthritic hands, small children, and anyone carrying groceries. They are a practical choice in homes where several generations share the same doors.
  • Mortise lock installation: a mortise lock sits in a deep pocket cut into the edge of the door and combines the latch and bolt in one body. You find them on older commercial doors and some older homes. They take careful cutting and the right trim, and they are not a bolt-on swap for a standard cylindrical lock.
  • Residential lock installation in general: entry doors, side doors, back doors, and the door between the house and the garage. Each can take a different level of hardware depending on how exposed it is.
  • Commercial lock installation: grade-rated hardware, keying that suits staff turnover, and sometimes exit devices or closers to go with the lock.

Why do older La Puente homes so often need new locks?

Much of La Puente was built in the 1950s, during the postwar subdivision boom. The typical house is a single-story stucco tract home on a modest lot, often with a detached garage. Houses like that are now seventy-odd years old, and a lot of them are still wearing their original locksets, or a replacement from some earlier owner that nobody has looked at since. Springs weaken, latches drag, screws loosen in the door, and keys have been copied from copies for decades. At some point the better move is not another repair but a clean installation of new hardware.

There is also a practical local factor. The eastern San Gabriel Valley has hot, dry summers and mild winters, and there is no coastal salt air here to eat hardware. What does happen is seasonal movement: wood doors on postwar tract homes swell and shrink through the year. A lock installed with no thought for that will stick in the heat and rattle in the cool months. When we fit a new lock on one of these doors, we set the latch and strike with enough tolerance to ride out the seasons, and we note when the door itself needs planing or the hinges need tightening before the lock will behave.

Households here are often multigenerational, and security screen doors are a common retrofit. Both change what a good lock looks like. A grandparent may do better with a lever than a knob. A screen door that sits close to the main door can block a handle or crowd a deadbolt thumb-turn. We plan for those things up front instead of finding out after the hardware is on.

How do we install a new lock, step by step?

Every door is a little different, but the process stays consistent.

  1. You call (213) 577-1366. A person answers, any hour, and we ask about the door: wood, metal or glass-framed, what is on it now, and what you want changed.
  2. We agree on the lock type over the phone where we can, so the right hardware is with us when we arrive. Our mobile locksmith service comes to your address, and our storefront at 10740 Wilshire Blvd in Westwood is there if you would rather look at hardware in person.
  3. On site, we inspect the door and frame: thickness, edge condition, existing holes, whether the door hangs true, and whether a screen door or trim limits what will fit.
  4. We walk you through the options that suit that door, explain the trade-offs plainly, and give you the cost before any work starts.
  5. We prepare the door. That might mean reusing the existing bores with the correct adapter, drilling new ones, or cutting a mortise pocket in the edge.
  6. We fit the lock, align the latch and bolt with the strike, and reinforce the strike and jamb with long screws into solid framing.
  7. We test everything repeatedly, with the door open, closed, and swung hard, then hand over the keys and show you how the lock operates. We clean up the shavings before we leave.

What affects the cost of lock installation in La Puente?

We do not quote a number in a web page, because a lock installation can be very different from one door to the next. What we can tell you is what moves the cost up or down, so the figure you hear on the phone makes sense.

  • The lock itself. A standard grade deadbolt costs less than a high-security cylinder, and a quality lever set costs less than a mortise body with matching trim.
  • The condition of the door. A door that is already bored for a standard lock is a quicker job than one that needs new holes, a mortise pocket, or repair of an old, oversized bore.
  • How many locks. Several doors keyed to one key take longer to install, but the work is more efficient per lock than separate visits.
  • Keying. Keyed-alike sets, or a layout that suits a small business with staff, add planning and parts.
  • Frame and strike work. Soft or split jambs need reinforcing to hold a new deadbolt properly.
  • Door type. Metal, glass-framed, and solid wood doors each have their own prep and tooling.
  • Timing. A planned visit during the day is usually the more economical route compared with a late-night call-out, simply because after-hours work takes more of our time to cover.

Lock installation across La Puente neighborhoods

La Puente is served by ZIP codes 91744 and 91746, and the installation requests we expect differ by area. On the 1950s tract streets around the La Puente Park area, the usual job is replacing worn original locksets on postwar homes: pulling out a tired knob and a loose deadbolt and fitting a matched set that closes cleanly and takes a key without a fight. Front door lock installation is the most common version, often with a second lock for a side or garage-facing door.

In Old Town La Puente, the business district brings a different kind of job. Storefront doors there need dependable hardware that gets used all day, and an installation might be a new lock on a door that is outgrown its original one or a change after a tenant moves in. If an existing storefront lock is simply failing, that is closer to storefront lock repair than a new install, and we will tell you honestly which one you actually need.

Along the Hacienda Boulevard and Amar Road corridors, commercial lock installation is more likely, since that is where shops, offices and the limited apartment stock sit. Out toward the Valinda and Bassett border areas, which are adjacent unincorporated neighborhoods, the same residential and small-business work applies. Our storefront is in Westwood, about 29 miles from La Puente, which is why we like to settle the lock type on the phone before we leave. That way, the van arrives with the right hardware for your door and not a guess.

What about commercial lock installation?

A business door has a harder life than a house door. It opens and closes all day, gets pushed by people carrying boxes, and is often the first thing a would-be intruder checks. Commercial lock installation therefore starts with a different question: who needs to get in, and how often does that list change?

For a small shop, that might mean a heavy-duty cylindrical lock or a mortise lock on a storefront door, a separate deadbolt, and a keying plan so the owner, a manager and one or two employees each have the access they need and nothing more. For a larger setup it might involve exit devices, closers or a coordinated key system. We keep the broader hardware side on our page about commercial door hardware, and the focus here stays on the lock being installed correctly on the door.

One practical point: commercial doors often have fire or accessibility requirements that residential doors do not. If you are not sure what your door needs, ask us before you buy. We would rather you choose the right lock once than replace a wrong one.

Licensing and what to ask any locksmith

California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license. Whoever you hire for lock installation, ask for their license number before they start work and check that it is current. A real company will not mind being asked. It is one of the simplest ways to avoid the fly-by-night operators who quote one thing on the phone and another at your door.

Also ask what the quote includes, whether the hardware is a brand you can look up, and whether the person on your doorstep works for the company you called. These are fair questions, and the answers tell you a lot.

When a new installation is not the right answer

Sometimes the lock you have is fine and the real problem is the keys. If you have moved in, lost a key, or had a tenant leave, rekeying the lock changes which keys work without replacing the hardware, and it is usually the lighter-cost option. If the existing lock is simply worn out and the door is already bored for it, a straight lock replacement is the tighter fit. And if what you want is keyless entry, our smart lock installation page covers that properly.

We will say so if you are asking for the wrong service. A new installation is the right call when the door has no lock, when the existing lock cannot do what you need, or when you are changing the type of lock altogether.

Frequently asked questions

How long does a lock installation take?

A single standard lock on a door that is already bored for it is generally a short visit. New bore holes, a mortise pocket, jamb reinforcement or several doors take longer. After we see the door, we can tell you what to expect, and we do not rush the alignment, because that is what decides whether the lock works properly.

Can you install a lock I bought myself?

Yes, in many cases. Bring or show us the hardware first so we can check that it fits your door thickness and bore size. If it is a poor match, we will say so plainly before cutting anything and suggest an alternative.

Will a new lock work with my security screen door?

Usually, but the clearance between the screen and main door matters. A handle or thumb-turn that is too close can scrape or jam. We check this during the inspection and choose a lock shape and handle style that leaves enough room.

Can you put a lever handle on my existing door?

Often yes. Many levers fit the same bores as round knobs, so the swap can be simple. Some doors need small adjustments, and levers are not always interchangeable with every old latch. We confirm this at the door.

Do I need both a deadbolt and a knob or lever set?

For most exterior doors, yes. The knob or lever handles daily latching, and the deadbolt provides the stronger locking point. Some single-body locks combine both functions. We will explain which setup suits the door and how it is used.

Can you install a mortise lock on an older door?

Often, depending on door thickness and the condition of the edge. Mortise work involves cutting a deep pocket, so we check that the door can take it without weakening. If it cannot, we will suggest a different lock that fits properly.

Can all my new locks use the same key?

Yes. Keyed-alike sets are common for homes with front, side and back doors, and they can be set up for a small business as well. Tell us which doors you want on the same key when you call.

Do you install locks at night or on weekends?

Our phone is answered 24 hours a day, 7 days a week, at (213) 577-1366. If you are locked out and need a lock changed fast, that is covered by other pages, but we can talk through a night or weekend installation and what it involves.

What should I ask a locksmith before they install a lock?

Ask for their California BSIS LCO license number, what the quote covers, and which hardware they plan to fit. Make sure the person at your door works for the company you called. Anyone reputable will answer all of that without hesitation.
