Shut down lirc and run:

sudo ir-keytable -t

That should show you what each key on your remote is when you press
it.

You may need to work out which IR receiver you are using if there is
more than one.  Use:

sudo ir-keytable

to show all the IR receivers, then add a "-s rc1" option for example
to select the second (rc1) receiver.

To shut down lirc on systemd based systems (Ubuntu, Debian, ...), do
this:

sudo systemctl stop lircd

and to restart it afterwards:

sudo systemctl start lircd
