Smart Locks for Renters: Secure Your Apartment Without Drilling
Renting an apartment usually means living with the hardware your landlord installed. If you want the convenience of a modern smart home, you might assume a smart lock is completely out of the question because lease agreements forbid altering external doors. Fortunately, you can upgrade your rental home security with retrofit smart locks that fit perfectly over your existing deadbolt.
What Is a Retrofit Smart Lock?
Most smart locks on the market are full deadbolt replacements. Installing them requires you to remove the entire locking mechanism, swap out the exterior keyhole, and sometimes drill new holes in the door. This violates almost every standard lease agreement because it prevents the landlord or property manager from accessing the unit during an emergency.
A retrofit smart lock offers a clever workaround. Instead of replacing the entire lock, a retrofit model only replaces the interior thumb turn. The exterior keyhole remains completely untouched.
This design offers three major benefits for renters:
- Your landlord can still use their physical master key to enter the apartment.
- From the hallway or street, your door looks exactly the same as every other door in the building.
- When your lease is up, you simply unscrew the smart lock, put the original thumb turn back on, and take your tech to your next home.
Top Smart Locks for Apartment Renters
Several tech companies manufacture smart locks specifically designed to work with standard single-cylinder deadbolts. Here are the most reliable options available right now.
August Wi-Fi Smart Lock (4th Generation)
August is the pioneer of the retrofit smart lock market. Their 4th Generation Wi-Fi Smart Lock is roughly the size of a standard doorknob and sits flush against the inside of your door.
Unlike previous versions that required a separate plug-in hub, this model connects directly to your home Wi-Fi network out of the box. It typically retails for around $230, though you can often find it on sale for closer to $150 during major holiday events. The August app is highly polished, allowing you to grant temporary digital keys to dog walkers or friends. It also features an excellent auto-unlock function that detects your phone via Bluetooth and unlocks the door as you walk up.
SwitchBot Lock Pro
If you want a truly non-invasive installation, the SwitchBot Lock Pro is a fascinating budget option. Retailing for about $120, this device can actually grip your existing thumb turn without requiring you to unscrew anything.
SwitchBot uses strong 3M VHB adhesive tape or simple clamps to mount directly over your current lock hardware. A small motor physically turns the deadbolt for you. To control the lock remotely while you are at work, you will need to purchase the SwitchBot Hub Mini, which costs an additional $30.
Yale Approach
Yale is a massive name in traditional door hardware, and their newer Yale Approach lock is aimed directly at renters. Priced at approximately $130, this lock is slimmer than the August model and looks less like a tech gadget.
The Yale Approach comes with a separate Wi-Fi bridge that you plug into a nearby wall outlet. It connects seamlessly with the Yale Access app. Because Yale actually owns the August brand, the Approach shares much of the same excellent software backend, including reliable auto-locking capabilities and smart home integration with Apple HomeKit and Amazon Alexa.
Wyze Lock
For renters strictly focused on value, the Wyze Lock is a great choice. Selling for around $130, this kit includes everything you need, including the required Wi-Fi gateway.
One standout feature of the Wyze Lock is its built-in gyroscope. The lock knows if your door is actually closed or just hanging open. This prevents the motor from extending the deadbolt while the door is ajar, which can damage your doorframe.
Key Features to Consider Before Buying
When shopping for a retrofit lock, you need to look beyond just the price tag. Keep these specific features in mind:
Wi-Fi vs. Bluetooth Compatibility Every smart lock has Bluetooth, allowing you to control the door when you are standing right next to it. If you want to unlock the door for a friend while you are sitting in a restaurant across town, you need Wi-Fi. Make sure you check if the lock has Wi-Fi built into the device or if it requires a separate plug-in hub.
Battery Life Retrofit locks run on batteries, typically standard AA batteries or CR123 lithium cells. Because these motors have to physically turn a heavy deadbolt, battery life usually ranges from three to six months. The companion apps will send you multiple notifications when the power drops below 20 percent.
Auto-Locking Mechanisms One of the best reasons to buy a smart lock is peace of mind. You can set the lock to automatically secure the door after a specific time frame, such as three minutes after closing. This entirely eliminates the feeling of panic when you leave for a trip and wonder if you remembered to lock the apartment.
The Installation Process
Installing a retrofit smart lock takes about ten minutes and only requires a standard Phillips head screwdriver.
You start by placing a piece of heavy painter’s tape over the outside keyhole. This prevents the exterior half of the deadbolt from falling out onto the floor. Next, you unscrew the two screws holding your interior thumb turn in place. You attach the smart lock’s mounting plate to the door, slot the correct adapter over the metal tailpiece, and snap the smart lock onto the plate. You do not need to drill any new holes or modify the doorframe in any way.
Frequently Asked Questions
Can my landlord still get into my apartment? Yes. Because you are not replacing the outside cylinder, the physical key provided by your landlord will still manually turn the deadbolt from the outside.
What happens if the smart lock battery dies while I am outside? If the batteries die completely, the lock simply becomes a regular manual lock. You can always use your original metal key to unlock the door from the outside, just like you did before buying the smart lock.
Will a retrofit lock work on any apartment door? These locks only work on standard single-cylinder deadbolts (doors that have a thumb turn on the inside). They do not work on mortise locks, integrated handle locks, or deadbolts that require a key on both the inside and outside.
Do I need to ask my landlord for permission? While you do not alter the exterior of the door or change the keys, it is always a good idea to read your lease agreement carefully. Because the installation is temporary and causes no damage, most property managers do not mind, but clear communication prevents misunderstandings.
