They are the similar to one currently offered at a discount tool store... here.
I tired using a single pin method but had trouble and eventually switched to a rakeing method with this pick shown, I had it open (to my surprise) in under 1 minute. Here is the door propped open.

Here is what is inside one of them.
They both had the mounting hardware and a little piece of 'carpet' inside.

Door assembly with cover removed, key in lock position.

And with 'bolt' removed, key still in locked position.

Close up of electronics board. Solenoid in backround that retracts pin allowing bolt to slide past.

Another view of solenoid and how it catches the bolt. (key unlocked and turned, pushing down on ring in this picture)

Key mechanism that pushes down on ring connected to solenoid and pin that moves the pin down allowing the bolt to be retracted.

I want to make some new keys but the 'pins' in this lock are not pins at all. They are actually rectangles with windows that the key passes through, the windows are different heights that will require a different 'bitting' for the key. Ill take some pictures and post them this week.
Thanks all.
