Dreamed up by a hardware startup called Apigy, Lockitron is an easy-to-install app-connected smart home solution that promises to turn almost any common deadbolt into a smart keyless entry system.

Building on early success with a deadbolt replacement solution, Apigy designed Lockitron as a standalone product that can be operated over the Internet via Wi-Fi, or directly from an iPhone through Bluetooth 4.0. Like many hardware startups, however, Apigy encountered a number of problems during manufacturing, missing deadlines due to unforeseen complications and quality control issues.

Nearly two years after a successful crowd-funding campaign, Lockitron is finally shipping out to backers in quantity. Unfortunately, there are still problems with the current software and some promised features are noticeably absent.


While the basic dimensions of U.S. deadbolts are standardized, internal mechanics like the degree of rotation required to actuate the lock varies from manufacturer to manufacturer. For example, Schlage requires a 90-degree turn to engage and disengage the bolt, whereas products made by Kwikset need a more substantial 120-degree turn.

If adjusting for varying locking ratios wasn't hard enough, some locks have a deadbolt lever located centrally in the decorative mounting plate, while others keep the pivot point off-center in the fascia's lower third.

To work around these roadblocks, Lockitron employs a sensor suite and motorized turning ring that automatically programs locking start and stop positions, determines appropriate force and can even be activated by knocking. A rubber insert grasps the deadbolt lever and can be cut or 3D printed for the perfect fit.

As seen in the image above, Lockitron boasts a minimalist design, with a housing element made of sturdy metal covered by a glossy plastic faceplate and knob. Instead of running flush against the door, the top cover leaves about a centimeter of chassis showing. The recessed area hides indicator lights and a multifunction button, both of which are located on the unit's right side.

Installing Lockitron

Mounting Lockitron is a straightforward process and in most cases only requires a Philips-head screwdriver (included) to install. Apigy provides a C-shaped mounting plate that goes between the door and decorative deadbolt plate to create a solid anchor onto which Lockitron can latch. The C-plate features grooves to match up with common deadbolts assemblies, as well as tabs that interlock with Lockitron's chassis.

Installing Lockitron:

  1. Loosen the deadbolt screws from the interior door.
  2. Slide the C plate behind the deadbolt decorative mounting plate.
  3. Fit the mounting plate into the appropriate groove on the C Plate to help center it for Lockitron.
  4. Tighten the deadbolt screws while making sure the lever turns with the least amount of resistance possible. Deadbolts are fiddly, doors are drilled with a decent amount of inaccuracy, and if everything isn't lined up just right, you may have a lever that's hard to turn. Take the time to get it as smooth as possible.

Once all that's done, hold the Lockitron at an angle to the door, slip it over the tabs on the C plate, rotate until it's vertically straight up and down with the door edge, and it's mounted. It sounds hard, but actually wasn't bad — just took a bit of fiddling to get right.

Next, we downloaded the app, which guided us through the process of setting up Lockitron's software. After entering our Wi-Fi network credentials, the app asked to connect our Lockitron with Apigy's cloud service by taking a picture of a barcode attached to the device chassis.

This next part is pretty cool. How do you get a device that's not on your Wi-Fi network, on your Wi-Fi network without a keyboard to enter in details? In Lockitron's world, you aim your phone's display at the upper right corner of Lockitron and the app flashes pattern of pulses captured by an onboard photo sensor.

After setup we encountered our first problem. We started out using a Kwikset deadbolt we had on hand. Since the app doesn't ask what type of deadbolt you have during initial setup, the default is to the smaller turning angle of Schlage locks, so the motor would never turn far enough to fully deploy the bolt.

We went out and bought a Schlage lock to finish the install only to find out from Apigy support that a hidden setup webpage allows users to reprogram Lockitron's turning radius. Doing so has a negative effect on battery life, but is necessary for Kwikset-type deadbolts.

A better solution would to have the app query what deadbolt we were using, or whether we needed a wider turning radius, before finishing setup procedures.

In use

Once Lockitron was installed and set up, we started to see the kinds of compromises Apigy made to get the product to market. For example, Lockitron currently relies on Wi-Fi instead of Bluetooth for connectivity. Because Wi-Fi has a high energy cost on the included AA batteries, the firmware aggressively puts Lockitron to sleep to conserve power. Sleep/wake scheduling is seemingly arbitrary and manual activation is limited to turning the lock or knocking on the door.

When leaving the house, this isn't all bad. We unlock the door from inside, exit, pull the door closed, and it's still awake from unlocking it. From there, we can open the app and swipe to lock. This is mostly reliable, although the app sometimes incorrectly displays that Lockitron is asleep. We end up standing in front of the door, tapping and swiping, waiting to hear the lock. This takes longer than just using a key, and is kind of annoying.

We really had hoped to be able to sit in the car and lock the door, or even check the status and lock it if we've forgotten to lock it while we're out, away from the house. If Lockitron had a consistent connection to the network, we'd have been able to do this.

Returning home is equally difficult. Most people have to take out a key, insert it into the lock, and turn to open the door. Our former lock was a keypad deadbolt, so we had to enter a combination and open the door. Using Lockitron means we take out our phone, open the app, knock on the door, tap on the screen, swipe the screen, and unlock the door.

The idea of knock-to-wake is good from a power management standpoint, but lousy when it comes to actually opening a door. If it were raining and we had to wait in the rain for the door to wake up, that's a poor experience.


Lockitron is a novel idea and the hardware definitely has potential, but the current execution is not quite up to snuff. Most troubling is the lack of quick access and remote monitoring, as these are the very features that make a smart lock smart.

Bluetooth Low Energy or other low power system (z-wave with an ethernet-to-z-wave dongle at the router, not unlike the Peel universal remote control from a few years ago) would allow Lockitron to stay awake and accessible from the outside world, and not leave us with uncertainty over whether or not the door was locked. BLE has yet to be incorporated in any useful way, however.

Apigy is constantly rolling out software updates for better Wi-Fi connectivity, modified wake/sleep patterns, higher app monitoring accuracy and better mechanical operation. The company also plans to activate "Sense," a proximity-aware method of keyless entry based on Bluetooth 4.0 that was on the list of hyped features.

Hopefully Apigy will make the necessary changes to make good on its promises, but with a host of currently deactivated or sometimes-working features, using Lockitron is more of a hassle than it's worth.


  • Easy install process
  • Solid hardware with big potential
  • Good app (when it works)


  • Many features, including "Sense," not yet active
  • Poor sleep/wake cycling
  • Remote lock monitoring is spotty

Score: 2 out of 5

Where to buy

Lockitron is available for preorder through Apigy's website for $179. Shipment time is unknown, though the company has yet to deliver all crowd-funding orders.
