Which type of wood drill bit to use

I cannot open our gate with the remote transmitter. We didn't use the gate for ~5 years (the main battery died), but before the battery died, it worked perfectly. It's a solar gate. I bought a new battery, and the gate works well when hitting the "go" button on the gate controller main board, but I cannot open it with the remote transmitter/receiver. When I hit the button on the transmitter, nothing happens. :( The batteries in the transmitters are new (we have two transmitters), and the green LEDs on the remotes shine bright. I never touched the receiver when replacing the battery. I can't find any documentation on the receiver board, so I'm at a loss. Do I have to buy a new receiver? There are DIP switches on the receiver board, but maybe it's also a rolling code receiver, and it lost it's program during the blackout? There is an unlabeled button on the board, maybe that's the programming button? Does anyone know how to get this thing working? Thanks!!!

The 3 different hardwired buttons located inside and outside the garage work fine. Both of my SUVs and all remotes do not work. The Lock feature isn't enabled (no blinking). When using a 'remote' (car/physical remote), the LiftMaster blinks one time and nothing happens. Since the hardwired opens/closes, the motor is operational. Since the LiftMaster blinks using a "remote", then it must be receiving a signal. Where should I start troubleshooting?
