I install the key on my original module, because the circuit boards are different.

I weld two wires on the remote button that performs the opening of the gate and at the other end I weld them to the board corresponding button.

A small cut to don't pinch the wires:

I weld two wires on the contacts of the battery in the remote and at the other end I dug them to a positive and a Vehicle Mass.
Thus avoiding the use of a battery. (This operation can only be performed if the remote uses a 12V battery).
I applied the remote with double-sided tape behind the block:
