There is a USB mini-B connector on the bottom of the keypad, externally. | |||
There are three LEDs on the outside: amber (code failed), red (battery low), and green (opening). | |||

== Mode of operation == | |||
1) Key in a code, hit hash. It locks shut (you can do this before you shut the door, as the bolt is sprung and it will latch). | |||
2) Key in the same code, hit hash. It opens. | |||
=== Notes === | |||
* The bolt is sprung, and will remain in whichever position it's set in regardless of power state. | |||
* The lock's "locked" state is based on the position of the bolt, which you can push in. So if you've forgotten the code, and the door is open, you can just hold the bolt into the open position and it'll accept a new code (as in step 1). It'll remain in the shut state until you enter the code again. | |||
* Codes seem to be remembered across battery removal, at least in the short term. | |||
* There appears to be some kind of internal power source, as after the batteries are removed, holding the "reset" button will illuminate the red light for a few seconds. Then (I think) the code is forgotten (although the lock is still not open!). | |||
* Presumably there is a master code for letting you unlock a forgotten code, or else the USB connector has something to do with it. However, the USB connector does not appear to present a USB device. | |||
* The USB connector can be used to power the lock in the case of a battery failure, however with a fairly modern Macbook Pro as a power source this was very intermittent (how intermittent seems to vary between locks). Repeatedly cycling the USB power until pressing a key made a beeping sound meant that the lock could be used as normal, powered via USB. | |||
