I have not used my BOSE CD player for a number of years. The remotes did not work when I replaced the batteries. Is it possible to repair or replace them?
I have the WAVE music system and the CD changer.
I have 2 remotes and neither of them will work .

If the remotes are infra red it is trivially simple to check them with a phone camera - there must be plenty of YouTube content explaining how.

Check the battery contacts are clean and firm.

A simple search on EBay or Amazon should throw up compatible remotes.
