This is generally true for any security device. If someone steals your keys, won't they have access to your home, car, etc.? To make it more secure, you would want to use multiple factors of authentication. For example, have a phone app that requires a password. Then, you would need to have your phone and knowledge of the password (this is known as two-factor authentication). I recommend starting down the rabbit hole of physical security if you want to learn more ways to make things secure.

Honestly, for this sort of security you just need to raise the bar high enough that someone can't create an "Easy button hack" to sell on ebay for the real common criminals. For that to happen, the lock needs to be more wide spread and stable than a Sparkfun hack. All of this is pointless anyway if they use the "brick" method (brick meet glass) to get past your amazing lock.

On the other end of the spectum, I doubt there are many elite-cyber-hacking criminals that also want to risk breaking into a common person's house. I also doubt they will scrutinize a small Sparkfun hack that has very low proliferation.

The whole point of this post is that the risk is low (IMHO, grain of salt included) because there are WAAAY easier targets or better payoff. Just don't have a flaw that leaves your house unlocked while you're gone. I will now completely digress and say that attention to security details for the sake of knowledge is a VERY worthy pursuit. Hack away fellow Sparkfunions!

Implementation is key. If you used Wifi for the access, then you already have 1 factor authentication as long as it is secure. If you want to allow access outside of the Wifi, change the ports used by the IoT device, use SSL, and setup your application and router to support port knocking. Put a password on your phone or don't cache the password to your locking device. If you want to protect against brute forcing the password, then consider increasing the delay between failed password entries by some increasing scale. Consider having a dual radio for Wifi and Bluetooth. Wifi only passwords have a single use (think remote open for a family member, etc). Dual routed wifi and bluetooth password (behind the scene in the app) is the required for normal use.

I think you're missing the point of IoT and diy: if you want it your way, you should make it your way - create a video if you want. They aren't sending with electronics for a reason, however the majority of tinkerers would use it exactly as showcased. But isn't the idea to do what you want?

I finally finished the hookup guide! It can be found here. Hope that helps.

Hookup guide is done. It can be found here. Hope it helps!

A hookup guide for the Lockitron is on my list of things to do, but for now, the code that I used in the video can be found here: https://github.com/sparkfun/IoT_Airlock/blob/master/RFduino/BLE_Lock/BLE_Lock.ino. Note that it is for the RFduino.

When we tore apart the motor housing, the motor had no markings. With some testing, it looked like the motor operated between 3 - 9 VDC and would draw 500 mA (moving the rings) and 3+ A stalled. The full guide here.

Each Lockitron comes with a "C-Plate." There are instructions on how to install the assembly in the Installation guides in the Documents section (check page 5 in the written guide, for instance). There some unscrewing that will need to take place so keep that in mind. :)

Not really. The switched are held in place by tiny standoffs. You could drill new holes or supply your own switches. There are more "ridges" or "bumps" than what's really needed, so it's possible that it's already set up for locks with longer rotations.

You can sort of shim some electronics in between the battery compartment and the side with the wireless symbol. That's where the original one had the electronics. You'd likely have to roll a custom board to make it fit, though.

The original Lockitrons came with electronics (an Electric Imp and a Bluetooth module on a custom PCB), which is what the installation video is for. You can buy the Lockitrons from SparkFun if you want to roll your own electronics (i.e. it is just the housing and motor). If you want the complete solution (with electronics), you'll have to buy them from Lockitron.

I'm assuming indiegogo? Ah the wonderful world of 'starters.

An electric striker involves cutting a bigger hole in your door frame, which you can't really do with a soldering iron, a computer or a pair of wire cutters. If you're more electronically inclined than mechanically inclined (either in terms of the tools you have or your skills) this would be a good way to build your own "smart" lock.

Please provide electrical striker details.

They kinda did. Watch the "Installation Video" and you can see their electronics (not included in this version) placed vertically on the right side. It's up to use to design your own custom PCB to fit in this space if you don't want the electronics outside.

Nope. I added all the wires so that I could control a deadbolt from an RFduino :)

Watch the video?
