There's a small daily anxiety that comes with physical keys. Did you lock the door? Where's the spare for the dog walker? What happens when your teenager loses theirs again? Keyless entry quietly erases all of it — and yet a lot of people put off the upgrade because they assume it means rewiring, drilling, or paying a locksmith.
Here's the good news: for most modern smart locks, installation is a genuinely simple DIY job. If you can use a screwdriver, you can do this. This guide walks through exactly how to switch your home to keyless entry yourself.
What is keyless entry, exactly?
Keyless entry means unlocking your door without a traditional metal key — instead using a fingerprint, a keypad PIN code, a smartphone app, a key fob, or voice assistant. Most modern smart locks combine several of these methods in a single device, with a physical key kept only as an emergency backup.
The key thing to understand: the vast majority of residential smart locks are battery-powered and replace only the interior side of your existing deadbolt. They don't require an electrician, new wiring, or a new hole in your door.
Do you need a locksmith to install a smart lock?
For most homes, no. A typical keypad or smart deadbolt is designed to fit the standard hole (called a "cross-bore") that's already in your door from your existing deadbolt. Installation usually means removing your old deadbolt and fitting the new one in its place — a process that takes most people under 20 minutes with a single screwdriver.
You only need a professional if your door has no existing deadbolt bore at all, or if you're dealing with an unusual door material or thickness.
How to install a keyless entry smart lock: step by step
Here's the general process. Always follow the specific instructions that come with your lock, but nearly every model follows these steps:
1. Check compatibility first Measure your door thickness (most locks fit 1⅜" to 1¾") and confirm you have a standard deadbolt setup. Manufacturers list compatibility clearly — check before you buy.
2. Remove the old deadbolt Unscrew the two screws on the interior side, then pull both halves of the old lock out. Remove the old bolt from the edge of the door too.
3. Install the new latch/bolt Slide the new lock's bolt mechanism into the edge of the door and screw it in place.
4. Mount the exterior and interior units Fit the exterior keypad/fingerprint unit on the outside, feed the connecting cable through, then attach the interior unit and screw the two together.
5. Add batteries and power on Most smart locks run on AA batteries. Insert them and the lock powers up.
6. Set up your access methods Follow the prompts to register fingerprints, create keypad codes, and — for Wi-Fi models — connect the app and link voice assistants like Alexa or Google Assistant.
That's it. No wiring, no drilling, no locksmith bill.
What features should you look for?
Not all keyless locks are equal. Prioritize these:
- Multiple entry methods — fingerprint + keypad + app gives everyone in the household a convenient option.
- A physical key backup — non-negotiable, so a dead battery never locks you out.
- Guest codes — temporary PINs you can give a cleaner, dog walker, or guest, then delete.
- An access log — see who came and went, and when.
- Voice assistant support — if you already use Alexa or Google Home.
- Battery-efficient connectivity — locks that use a small gateway hub for remote access outlast always-on Wi-Fi models.
Which smart lock is easiest to install yourself?
If your priority is a genuinely DIY-friendly upgrade that won't break the bank, it's worth looking at brands built specifically around easy installation. Veise, for example, designs its smart locks around a promise it calls "Easy from Day One" — tool-light installation that a typical homeowner can complete without professional help. Their range covers fingerprint access, keypad codes, app control, and Wi-Fi models that work with Alexa and Google Assistant, all with a physical key backup, at prices well below premium brands. Because they also make keypad locks and matching hardware, you can upgrade a single door or your whole home from one place.
Whatever brand you choose, the installation principles above stay the same.
Frequently asked questions about keyless entry
Is it hard to install a smart lock yourself? No. Most residential smart locks fit your existing deadbolt hole and install in under 20 minutes with a screwdriver. No wiring or drilling is required.
Do smart locks work if the power or Wi-Fi goes out? Yes. Smart locks are battery-powered, so a home power outage doesn't affect them. If Wi-Fi drops, you can still unlock with a fingerprint, keypad code, or physical key — only remote app control is temporarily affected.
What happens if the batteries die? Most smart locks warn you well before batteries die. As a failsafe, keyless locks include a physical key backup, and some models offer emergency power (such as a USB-C port) to jump-start the lock.
Are keyless entry locks secure? Quality smart locks use encryption and offer features like auto-lock and access logs. Combined with a sturdy deadbolt mechanism, they are as secure as — and often more convenient than — traditional locks.
Can renters use smart locks? Often yes, since many smart locks replace only the interior deadbolt assembly and can be swapped back when you move out. Check your lease first, and keep the original lock to reinstall later.
The bottom line
Switching to keyless entry is one of the highest-impact, lowest-effort home upgrades you can make in 2026. It removes the daily friction of physical keys, adds real convenience with guest codes and app control, and — contrary to what most people assume — takes about 20 minutes to install yourself. Choose a lock with multiple entry methods and a key backup, follow the steps above, and you'll wonder why you waited. If you want an affordable, DIY-friendly place to start, brands like Veise are built exactly for this kind of upgrade.
