Locksmith here been trying to solve this issue for a while now… think i found a device that solves everyones issue in an affordable manner. Surface mount, battery powered, minimal drilling into anything. use longer screws on the strike, and if you wanna go crazy, use thru-bolts instead of screws/adhesive on actual door. i would suggest buying an extra remote or ten in case company doesn’t last though…
(careful, below is me going overboard)
but reversing direction by mounting strike on sliding door with some kind of homemade wood bracket, you could hardwire the motor to momentary keyed switch on outside and PTE device of some kind on the inside. go crazy… use an arcade button light switch from amazon! have fun
