Why Changing Locks
Lock changes aren’t only for emergencies. A lot of West Covina homeowners and business owners schedule lock replacement as a simple security upgrade, especially when the existing hardware is worn, loose, or outdated. If your key sticks, your latch doesn’t catch smoothly, or you need to “wiggle” the handle to make the door lock, that’s usually a sign the lock is nearing the end of its reliable life.
Lost keys are one of the most common reasons people call for a lock change. Even if you think you dropped them somewhere harmless, the risk is that someone finds them and figures out where they belong. If the keys had any tag, label, or connection to your address, changing the lock can be the easiest way to get peace of mind fast.
Moving to a new house or office is another big one. You never really know how many copies of your keys are floating around from previous tenants, contractors, cleaning crews, or old employees. A fresh lock change gives you a clean start, and you control exactly who has access from day one.
Stolen keys are different from lost keys because there’s intent involved, and that changes the risk level. If a purse, backpack, or work bag with keys was taken, we typically recommend a same-day lock change or rekey depending on your hardware and security goals. Quick action matters, and a mobile locksmith can handle it at your location without you waiting days for a store appointment.
Burglary repair is another situation where replacing the lock is often necessary. After a forced entry, the cylinder, strike, latch, or the door edge can be damaged in ways that make the lock unreliable. We can replace the lock, reinforce the strike area, and make sure the door closes and locks correctly again, so you’re not living with a patched-up fix.
Security upgrades are also very common in West Covina, especially when people move from basic builder-grade hardware to stronger deadbolts, higher-security cylinders, or modern smart locks. A new lock isn’t just about the key. It can improve pick resistance, reduce bump-key vulnerability, and tighten up the overall fit between the door and frame.
Lock Change Vs Rekey
A lock change means we remove your existing lock hardware and install a new lock. This is ideal when the lock is damaged, low quality, outdated, or when you want a different style or higher security. It’s also common when you want to change from a knob lock to a handle set, add a deadbolt, or switch to a smart lock.
Rekeying means we keep the same lock hardware, but change the internal pin configuration so your old keys no longer work. It’s usually faster and can be more cost-effective when the existing lock is in good condition and you’re happy with the hardware. Rekeying is also great when you want multiple locks keyed alike so one key opens several doors.
When we arrive, we’ll check the condition of the lock, door alignment, and what you’re trying to accomplish. Then we’ll recommend the option that makes the most sense for security, budget, and long-term reliability. If you’re unsure, start with pricing and we’ll guide you from there.
Deadbolt Vs Mortise
Deadbolts are extremely common on residential doors and many light commercial doors. A deadbolt typically has a bolt that extends into the door frame, and it’s designed to resist forced entry better than a basic spring latch. Many setups include a separate deadbolt above a handle or knob, creating a simple and strong two-piece lock arrangement.
One detail that matters with deadbolts is cylinder placement. In a typical deadbolt lock, the cylinder is built outside of the door frame, mounted through the door itself, and it throws the bolt into the frame when you turn the key or thumbturn. This design is one reason deadbolts are so popular: they provide a solid locking action without relying on the handle latch.
Mortise locks are more common on commercial doors, older homes, and certain high-end residential setups. Instead of mounting mainly on the surface, a mortise lock fits into a pocket (a “mortise”) cut into the edge of the door. Mortise locks often combine latch and deadbolt functions in one body, which can feel sturdier and smoother when properly installed.
Which one is “better” depends on your door and use case. Deadbolts are often simpler, cost-effective, and great for standard residential doors. Mortise locks are excellent for heavy-use doors, storefronts, and doors where you want a robust, integrated locking mechanism, but they require precise fitting and the right door preparation.
If you’re in West Covina and you’re not sure what you have, we can identify it quickly on-site and recommend the correct replacement. If you’re upgrading from a basic deadbolt to something stronger, or replacing an older mortise lock, we’ll make sure the new hardware fits cleanly and operates smoothly.
Smart Locks
Smart locks are popular because they make access simpler and more controllable. Instead of handing out extra keys, you can use codes, schedules, temporary access, or app-based control depending on the model. They’re great for busy households, small offices, rentals, and anyone who wants to reduce “who has a key” stress.
The big advantage is convenience without losing security, as long as the lock is installed correctly and paired with a solid door and frame. Many smart locks still use a real deadbolt, and the “smart” part is the way you unlock it. That means you can still get strong physical security while gaining modern access features.
There are two main categories: standard smart locks and retrofit smart locks. Standard smart locks replace the entire deadbolt hardware, including exterior and interior components, and often give a clean, integrated look. Retrofit smart locks usually keep the existing exterior key cylinder and replace only the interior thumbturn with a motorized unit, which can be helpful if you want to keep the outside appearance the same.
Standard smart locks are often best when your existing lock is worn, mismatched, or low quality, or when you want a full upgrade. Retrofit smart locks can be a good fit when you already have a high-quality keyed cylinder, or when you’re in a setting where you want to maintain a consistent exterior look across multiple doors.
We help West Covina customers choose the right smart lock for the door thickness, backset, and daily use, then we install it, align it, and test it so it doesn’t bind or drain batteries from friction. A smart lock should feel smooth and reliable, not like it’s struggling every time it turns.
Do It Yourself VS Using Professional Locksmith
DIY lock changes can work if the door is standard, the holes are clean, the hardware matches your door prep, and you’re comfortable measuring backset and aligning the latch and strike. The upside is cost savings on labor and the ability to install on your own schedule. The downside is that small alignment mistakes can cause big reliability problems later.
A professional locksmith brings the right tools, knows how to spot door and frame issues, and can handle surprises like stripped screws, misaligned frames, unusual mortise cutouts, and worn door edges. The big advantage is speed and a correct fit, especially on commercial doors or older homes. Another advantage is warranty on parts and labor, so you’re not stuck redoing the job if something binds, loosens, or fails.
DIY can also void certain product warranties if the lock is installed incorrectly, and it can create security gaps if the strike isn’t reinforced or the latch isn’t fully seating. With a pro install, you get a tested result and an upfront plan, especially important if you need a secure door today. If you want it done once and done right, a mobile locksmith is usually the safer call.

Frequently Asked Questions
Do I need to change my locks after moving into a new place?
Yes, it’s one of the simplest security upgrades you can do. You don’t know who has copies of the old keys, and changing or rekeying resets access immediately.
Is rekeying as secure as changing the lock?
Rekeying can be very secure when the existing hardware is high quality and in good condition. If the lock is worn, damaged, or low grade, a lock change is usually the better move.
How long does a typical lock change take?
Many residential lock changes take about 20 to 45 minutes per door when the door prep is standard. Commercial or mortise hardware can take longer depending on fit and alignment needs.
Can you match multiple locks to work with the same key?
In many cases, yes. We can often key alike compatible locks, or rekey existing locks so one key works across several doors when the hardware supports it.
Do smart locks work on any door?
Most standard doors can accept smart locks, but door thickness, backset, and alignment matter. We’ll confirm compatibility and install it so the motor doesn’t bind or fail early.
What’s the difference between a standard smart lock and a retrofit smart lock?
A standard smart lock replaces the full lock hardware, while retrofit models typically keep the exterior keyed cylinder and replace the interior thumbturn. Retrofit can be great when you want to keep the outside look the same.
Can you replace a mortise lock on an older door?
Yes, and it’s common in older homes and many commercial doors. Mortise work requires careful sizing and fitting, and we’ll help you choose a compatible replacement or solution.
Should I change locks after a break-in or attempted break-in?
Usually, yes. Even if the door still locks, internal damage can make it unreliable, and you may want an upgrade to stronger hardware or reinforced strike plates.
Do you provide a warranty?
Yes. We offer a 6 months warranty for parts and labor, and we’ll explain what’s covered based on the hardware installed and the service performed.
Will I know the price before you start?
Yes. We provide estimates, then the technician confirms the final price after diagnosing the door and lock situation on-site, before any work begins.
