Bose RC28T1-27 Remote For AV28 PCB Schematic

[Chaks]

My Bose RC18T1-27 Remote Control for Lifestyle 18 Needs Repair as half of the buttons is not functional due to pcb corrosion (at the bottom). Please see images.
Can anyone help me with some suggestion so that i can make the upper half of the clean pcb buttons operational (which I normally use)so that i can still use the remote.
If anyone can point me to a pcb schematic of the remote so that i can cutoff the damaged buttons and make the other good buttons work.

Is there a way to test if the remote is sending rf signal when a good button is pressed. This is a rf remote so no led or IR signals.

You can use your cell phone camera and press a button on remote. You will see a light through the camera on the screen. They also sell remote control button repair compound.

Can you obtain a replacement remote? I have found a replacement is always the better option if there are multiple problems.
