iLoq - self-power generating electronic lock teardown

[Tuppe]

Hi,

I was interested to see how this self-power generating electronic lock works, so I disassembled it. I thought someone else might also find this interesting, so I decided to post reverse engineering stuff here. I did this just out of curiosity.

It works by generating the power from the key push-in motion. It has SHA encryption which is taken from the key using 1-wire protocol. The MCU is most probably Maxim Deepcover series.
Here's some patent information:

I got few questions, if someone more experience can spot what is going on (images in attachements):
1. The generator goes directly to chips 2 and 3, which have exactly the same configuration. Both have 0328 marking. What these components are? LDO?
2. Chips 4 and 5 are weirdly connected to power and MCU and have SGAJ marking. What these components are? MCU regulator?
3. Chip 6 is next to microcontroller, with SICX marking. What this might be?

I think the layout should be fairly trivial to anyone with experience in electronics design. If someone wants to get some more information, I can take a closer look of it.

Here's a video of how the lock operates (not my video). Motor and PCB on the other side of the lock:


The lock is opened using the same motor that generates the power. Because the motor actuates only a tiny motion to unlock so I assumed there is a possibility to bypass the lock using high power magnets. I couldn't actuate the lock using small neodymium magnets. Is it possible for the motor be 100% shielded so that not even a monster magnet attached to a power drill can open it?

I'm having a really hard time following your hand-drawn schematic.. any chance you could lay it out in a schmatic capture software?
