Why Changing Locks
Most people call for lock change service after one of these moments: lost keys, moving to a new house/office, stolen keys, or a scary incident that triggers a security upgrade. Even if nothing “bad” happened, it’s smart to take control of who can access your property. A fresh lock or a rekey restores that control immediately.
If you moved into a new home or leased a new suite, you can’t know how many copies of the old keys exist. Past tenants, contractors, cleaners, or previous employees may still have them, and that uncertainty is the real risk. In many cases, changing locks or rekeying them on day one is the simplest way to start clean.
Stolen keys are different from lost keys because there’s intent and a potential target. If a purse, backpack, or work bag disappeared with your keys inside, replacing access points quickly is worth it. We can change the lock hardware, or in some situations rekey compatible locks, so the missing key can’t open anything.
After a break-in or attempted burglary, burglary repair and lock replacement often go together. Damaged strike plates, bent latches, misaligned frames, and cracked cylinders can turn a door into a weak point. We can repair the locking function, reinforce the setup, and recommend a stronger lock grade when needed.
A security upgrade also matters when your current locks are simply outdated or worn out. Sticky turns, loose knobs, and keys that need “jiggling” are early warning signs. Replacing the hardware before a full failure helps you avoid lockouts and keeps the door properly secured.
If you manage a property or run a business, lock changes are part of real operations. Employee turnover, tenant move-outs, and access control updates are normal, and you want a consistent system. We can help you standardize hardware, reduce key clutter, and keep entry points working reliably.
Lock Change Vs Rekey
A lock change means replacing the hardware on the door with a new lock, new cylinder, and new keys. It’s the best choice when the existing lock is damaged, outdated, low-grade, or you want a different style or higher security. A change is also common when you want to switch from a knob lock to a deadbolt, or you need a commercial-grade setup.
Rekeying means keeping the existing lock hardware, but changing the internal pins so the old key no longer works. It’s often a cost-effective option when the lock is in good condition and compatible for rekey. Rekey is great when you want multiple doors set to the same key, or when you like the current hardware and just want fresh key control.
Which one is better depends on the lock condition, the door, and your security goal. If the lock is worn, loose, or not a good brand/grade, replacement can be the smarter long-term move. If everything is solid and you simply want new keys, rekeying can be fast and efficient.
Deadbolt Vs Mortise
Deadbolts are the go-to choice for many homes because they’re simple, strong, and easy to service. A deadbolt throws a solid metal bolt into the strike in the frame, giving you better resistance than a basic spring latch. They’re common on front doors, side doors, and units where you want reliable security without complicated parts.
One key detail: in a deadbolt lock, the cylinder is built outside of the door frame, mounted through the door itself. That design makes deadbolts straightforward to replace and upgrade, because the main components sit on the door rather than inside a large pocket in the door edge. It also makes it easier to swap styles, finishes, and security grades without major carpentry.
Mortise locks are different and are usually seen on older homes, high-end doors, and many commercial doors. The lock body fits into a rectangular pocket (a “mortise”) cut into the door, and the trim and cylinder align with that internal case. Mortise hardware can feel more solid and can support features like integrated latch/deadbolt functions depending on the setup.
Mortise lock work is typically more technical because alignment matters and the door prep is more involved. If you have a mortise lock, we can identify the exact type and match the correct replacement or rekey approach. If you’re considering upgrading, we’ll explain whether converting to a deadbolt makes sense or if staying mortise is best for your door and look.
Smart Locks
Smart locks are popular because they make access easier to manage while still keeping strong physical security. Instead of handing out keys, you can use codes, phone access, or scheduled entry for guests, cleaners, employees, or deliveries. They’re especially helpful for rentals, home offices, and busy families that want fewer “where’s the key?” moments.
A standard smart lock is built as a smart lock from the start, with an integrated keypad or exterior smart trim and a full lockset designed around that system. These are great when you want a clean look and a complete upgrade, and they’re often chosen during renovations or when replacing multiple locks. Standard smart locks can offer stronger built-in integration, depending on the model and your door type.
A retrofit smart lock focuses on converting an existing deadbolt into smart operation, often by replacing only the interior thumbturn assembly while keeping the exterior key cylinder and hardware. Retrofits can be a good choice if you like your current exterior finish or want to keep a consistent look on the front of the door. They can also be simpler to install on certain doors, while still giving you app control and auto-lock features when supported.
We’ll help you choose between standard and retrofit smart locks based on your door prep, backset, clearance, and daily use. We also make sure the door closes and latches correctly so the smart features work as intended. A smart lock is only “smart” if the door alignment, strike, and latch are tuned properly.
Do It Yourself VS Using Professional Locksmith
DIY lock replacement can work if your door is standard, your measurements are correct, and you’re comfortable with alignment and door hardware. The biggest advantage is cost control, and you can do it on your own schedule. The downside is that small mistakes, like misaligned strikes or wrong backset, can cause sticky operation and weaken security.
Using a professional locksmith saves time and reduces the risk of buying the wrong lock or installing it in a way that fails later. You also get proper diagnosis when the real issue is the door frame, latch alignment, or worn out parts beyond the cylinder. With Lock Change Downey, you also get a warranty on parts and labor, so if something isn’t right after the service, you have coverage and a clear path to fix it.
DIY is best for simple swaps when everything lines up perfectly and you don’t need master keying, rekeying, or commercial-grade adjustments. A professional is best when security matters, when the door is unique, when the lock is high-security or mortise, or when you want a clean, durable result. In the long run, correct installation usually costs less than repeated fixes.

Frequently Asked Questions
Do I need to change my locks after moving into a new place in Downey?
Yes, it’s one of the smartest first steps because you can’t know how many spare keys exist. A lock change or rekey gives you fresh key control right away. We can also match multiple locks to one key when possible.
Is rekeying as secure as changing the lock?
Rekeying is secure when the lock hardware is in good condition and the cylinder is reliable. The old keys will not work after rekeying. If the lock is low-grade, damaged, or outdated, replacing it can be the better upgrade.
How long does a typical lock change take?
Most standard residential lock changes take about 20 to 45 minutes per lock when the door is aligned well. Mortise locks or commercial doors can take longer due to alignment and hardware complexity. We’ll give you a realistic time expectation once we see the door.
Can you rekey my locks so one key works for the front and back door?
Often yes, as long as the locks are compatible or can be made compatible with the right cylinders. This is a popular option for homes, rentals, and small businesses. We’ll confirm compatibility on-site.
What’s the difference between a deadbolt and a mortise lock for security?
A quality deadbolt is strong and simple, and it’s easy to upgrade and service. Mortise locks can be very robust and are common on older or commercial doors, but they require correct door prep and alignment. The best choice depends on your door type and usage.
Do smart locks work on any door?
Most doors can take a smart lock, but fit depends on the backset, bore hole size, clearance, and door alignment. Retrofit smart locks may work when you want to keep the exterior key cylinder. We’ll confirm what fits before installing.
Will my smart lock still have a key backup?
Many smart locks include a key cylinder as a backup, while some keypad-only models do not. If you want a physical key option, tell us and we’ll recommend models that include it. We also make sure the backup key turns smoothly.
Do you offer same-day lock change service in Downey?
Yes, we offer same-day mobile service when scheduling and parts availability allow. If you have an urgent situation like stolen keys or a break-in, let us know so we can prioritize. We’ll arrive ready to complete the job in one visit whenever possible.
Do you provide a warranty?
Yes, we provide a 6 months warranty for parts and labor on qualifying services and hardware. Warranty coverage depends on the specific product and usage conditions. We’ll explain what’s covered before we start.
How do I know the final price before you start?
We provide estimates up front, then confirm the final price after diagnosing the door and lock type on-site. You approve the final price before any work begins. That way there are no surprises after the job is done.
