Question about electronic locks from Denver's hackerspace

[Legion303]

Forwarding from another source:

So denhac has reached the point that we want (and might be able to
afford) to implement an electronic door solution. Without changing out
the door, it looks like we need to get a replacement handle assembly.
Does anyone have any pointers to cheap but functional solutions in this
area? Used hardware that's no longer deployed would be ideal.

Also anything we should be thinking about beyond failopen / failsafe
would be good. We bought a cheap strike plate from Amazon and
discovered it was pickable using a zip-tie... Not ideal.

post a vid or something on the zip tie shim

In retrospect, I probably shouldn't have quoted that part...let's discuss that in Advanced somewhere.

@Legion303:

The "source" needs to describe the door a little bit better than saying "it looks like we need to get a replacement handle assembly"... Is the lock presently in use: tubular, mortise, rim ?

Are they planning on/hoping for a stand alone device or are they interested in something hardwired ? Or is it one of those situations where the ultimate decision will be made based on whatever the fates lay upon them for free...

Cheap strike plates are cheap and doesn't sound like it was the right one for the application -- if the door is equipped with a latch protector plate it frustrates and complicates latch manipulation attempts...

one questions is what's there now, and what do you want to be there.

twin cities maker recently converted our proprietary rfid system to an open source system to reduce our key cost and add functionality. with existing magnetic catches all we needed to do was interface with the hardware, but i know several maker/hackerspaces have gone as low tech as adding a servo to the interior handle so that they're not forced to change out door hardware that already works.
