Keypad distance from base station

New to Ring and just installed the alarm system but my keypad in the detached garage loses connection often. It's about 100ft between the two but there are several interior and exterior walls in the way also. I have a range extender right next to the keypad in an outlet and the sensors in the garage seem to be fine. Does the keypad connect through the extender or only direct to the base station? If it's direct and anyone has any ideas or workarounds, that would be greatly appreciated. Thanks
