Basically, I want to take 2 of these connectors
join them into 1 connector, and connect them into this portbecause I want the keypad (the thing on the right) to unlock/lock 2 deadbolts (the thing on the left that takes AAA batteries).

I’m thinking a male to female (x2) splitter should do the trick but 1) I don’t know what this connection is called and 2) I wanted to get some input here on whether that would even work.

 

I would have concerns that each bolt has its own power supply (batteries), that are supposed to power the keypad. Differences in battery voltages would cause one bolt battery to discharge though the other bolt's circuit, causing problems.
You may be better off checking one of the bolt devices to see what actrually triggers the bolt motor, and run a wire from that to the second bolt so it triggers the same way.
Without schematics, hard to say if this is even possible. But, I would not recommend paralleling those connectors....

 

why dont you share model of the unit and picture of the smaller PCB from the other side?

 

Looks like a PBD crimp connector...

They have several types listed...

Damn, that makes sense. Thank you for pointing that out

I can’t seem to find the manufacturer or model, just many sellers. https://www.amazon.com/Electronic-C...rds=keypad+cabinet+lock&qid=1580402551&sr=8-6

I’ll order 1 unit for now and post a picture of the other side of the PCB board asap.
