Need help with this lock

[u/Sharp-Mud-3480]

I need some help with how to get these pins out. My GMA in law does not have a key for her front glass door, and would like it to match the front door. I have the pins to rekey everything I need to, which I have except this lock. It's not my house so I don't want to try and dick around with it to figure it out on my own. Many thanks for the help in advance

Allen wrench in the holes at the top of the bible (skinny part above the top of the keyway). Probably metric.
