Okay so the door is rigged. You can no longer open the side door from outside. Turns out the existing door had a pair of push buttons to lock and unlock it.
Rather than trusting y’all not unlock it and leave it unlocked I took the liberty of disabling the unlock button by hammering the brass plate flat and installing a captive screwhead. Its hackspace good enough.
If you want to undisable it you’ll need a flat head screw driver to take off the side plate and remove the disabling screw.
Longer term moving forward @JohnC found a box of door hardware including a new handleset which is much nicer. Unfortunately its not locked and there is no key present. @rsim any idea where that key ended up?
I have put this box of door stuff under the side door stairs in front of the mame cabinet.
Still on the list is reinforcing the frame with steel flatbar but that cam happen at any time and is not required for the rfid system to proceed.
So the other thing is we need to make sure we have an override key for the front door in case the batteries die or we are not getting into the hackspace easily.
*edit - bill pointed out that we will also have to leave the deadbolt open for the rfid to work, probably cant make it a double lock because fire exit but we could remove it entirely
