If you’re still using a traditional key to get into your home or office, you’re not doing anything wrong, but you’re probably missing out. Smart locks have gotten genuinely good over the last few years. Not just more convenient, but more secure, more flexible, and a lot easier to manage than carrying a key ring that grows every time someone new needs access.
At MLine Locksmith, we install smart locks for homeowners and businesses across the Main Line, from older colonials in Wayne to newer construction in Malvern. And we’ve learned that the difference between a smart lock that works great for years and one that causes constant headaches usually comes down to one thing: how it was installed.
This is something most people don’t think about when they order a smart lock on Amazon. The lock itself might be excellent. But if the door isn’t properly aligned, if the backset isn’t measured correctly, or if the strike plate isn’t reinforced, you’ll start noticing problems within weeks: a deadbolt that drags, a motor that strains, batteries that die faster than they should.
We see it regularly. Someone installs a $200 smart lock themselves, it works fine for a month, then starts acting up. By the time they call us, the issue isn’t the lock, it’s the door. Older homes on the Main Line especially tend to have some settling, slight frame warping, or non-standard bore holes that make DIY installation trickier than the YouTube video made it look.
When we do an installation, we assess the door first. We check thickness, backset measurement, bore hole diameter, and frame alignment before we touch the new hardware. If something needs to be corrected, we handle it on the spot. That’s the part that makes the lock actually last.
There’s no single answer here, it depends on how you’ll actually use it. Here’s how we typically talk through the options with customers:
Keypad deadbolts are the most straightforward upgrade. No app required, no connectivity to worry about. You punch in a code and you’re in. These are great for families, rental properties, or anyone who just wants to stop dealing with physical keys. You can set multiple codes, one for your kids, one for a housecleaner, one for a contractor and delete them whenever you want.
Bluetooth smart locks are a step up. They connect to your phone and can do things like auto-unlock as you approach your door. They work locally, so no internet is required, and the battery life tends to be solid. If you don’t need to control your lock from across the country, Bluetooth is usually the smarter choice, simpler setup, fewer connectivity headaches.
Wi-Fi smart locks give you full remote access from anywhere. Lock or unlock your front door from your office, check whether you remembered to lock up before bed, send a temporary digital key to a guest. The tradeoff is that they use more battery and require a stable home network. For families who travel frequently or landlords managing multiple properties, the convenience is worth it.
Biometric locks use fingerprint recognition for entry. They’re fast, they’re clean, and they eliminate the problem of shared codes. These are popular for home offices, primary entries where you want zero friction, and certain commercial applications where accountability matters. Setup requires careful enrollment, and we make sure every fingerprint registers reliably before we leave.
Not sure which direction to go? We’re happy to talk through your specific situation before you buy anything. Sometimes the best advice we can give someone is to skip the expensive Wi-Fi model and go with a simpler keypad and that’s fine with us.

We keep this straightforward. Here’s what to expect when you book a smart lock installation with us:
We start with a door and hardware assessment. Before anything comes off or goes on, we look at the door itself: thickness, backset, frame condition, existing hardware. This is the step most DIY installs skip, and it’s the one that matters most. A door that doesn’t close cleanly will fight a smart lock every single day.
Then we remove the existing lock carefully. No unnecessary damage to the door or frame. If your current deadbolt installation has been there for twenty years, we take our time.
Installation follows manufacturer specs, but with our own attention to detail, correct torque on mounting screws, secure alignment of the interior and exterior assemblies, reinforced strike plate positioning. These aren’t details that show up in the box instructions, but they’re what separates a properly installed lock from one that loosens up after six months.
After the physical installation is done, we handle the full electronic setup. Pairing with your smartphone, configuring the admin settings, programming your access codes, setting auto-lock timers, connecting Wi-Fi bridges if applicable. We don’t hand you a lock and a manual. We set everything up and make sure it works.
Before we leave, we test every entry method: keypad, app, manual thumbturn, backup key if the model has one, auto-lock function. We also walk you through the basics: how to add or remove users, how to create a temporary code for a guest, how to replace the batteries when the time comes. The whole process typically takes 60 to 90 minutes, depending on the door and the lock type.
For homeowners, the most common reason people call us is pretty simple: they’re tired of keys. Lost keys, copied keys, keys that need to be hidden under a rock for the dog walker. Smart locks solve all of that cleanly.
We also get a lot of calls from people who’ve just moved into a new home and want to rekey or replace the locks anyway at that point, upgrading to a smart lock is a natural step. You get fresh access control and modern security in one visit.
Rental properties are another common situation. If you manage a property in Berwyn or Ardmore, being able to change access codes between tenants remotely, without rekeying the physical lock saves real time and money.
Whatever the reason, we handle residential installations the same way: careful, clean, and with a walkthrough at the end so you actually know how to use what you paid for.
For businesses, smart locks offer something beyond convenience, they give you control and accountability over who’s accessing what and when.
We’ve installed commercial smart lock systems for offices, small businesses, and multi-door commercial properties across the Main Line. Common applications include employee access codes with scheduled permissions, restricted areas that only certain staff can enter, and audit trail capability on models that support it. That last feature knowing exactly who unlocked a door and when is something traditional locks simply can’t offer.
Commercial doors also take more abuse than residential ones, so we make sure the hardware we recommend and install is rated for high-traffic use. No point putting a residential-grade lock on a door that opens 80 times a day.
We provide broken key extraction services throughout Delaware County and Chester County:
Delaware County: Media, Upper Darby, Bryn Mawr, Springfield, Havertown, Broomall, Drexel Hill, Newtown Square, Glen Mills, Lansdowne, Darby, Clifton Heights, and throughout Delco.
Chester County: West Chester, Exton, Downingtown, Paoli, Malvern, Devon, Wayne, Berwyn, Villanova, St Davis, Phoenixville, and across the county
If you’re in either county, we’ll get to you.
Every smart lock installation we do comes with a 1-year warranty on parts and labor. That’s not standard in this industry, and we offer it because we stand behind the quality of our work. If anything we installed isn’t performing the way it should within that first year, we make it right.
We’re licensed and insured, and we’ve been serving the Main Line community with that same approach on every job, residential or commercial, simple keypad swap or full commercial access control system.
Yes, absolutely. If you’ve already bought one online or from a retailer, we can install and configure it. Just let us know the brand and model when you call so we can confirm compatibility with your door.
Yes. Smart locks run on batteries, not your home’s electrical system, so a power outage won’t lock you out. We always make sure backup battery access is in place during installation.
Depends on the model. Many popular smart locks integrate with major smart home platforms, but not all of them. If compatibility with your existing setup matters, mention it before you buy, we can point you toward models that will work seamlessly.
Most smart locks last anywhere from 6 months to over a year on a set of batteries, depending on usage frequency and lock type. Wi-Fi models tend to drain faster. We’ll give you a realistic expectation based on what you install.
Our work is covered by a 1-year warranty on parts and labor. If something goes wrong with the installation or the hardware within that window, we come back and fix it. No runaround.
No, most modern smart locks make this simple through an app or keypad menu. We show you exactly how to do it before we leave.
If you’re thinking about making the switch to a smart lock, the best next step is a quick conversation. We can help you choose the right system, answer questions about your specific door, and schedule an installation that works for you.
