It definitely isn't comaptible with a Sony Blu-Ray player. I don't think Kameleon style remotes are still being produced, and there haven't been any made that are compatible with the Sony Blu-Ray players.

Some Kameleon remotes are upgradeable using an internal modem. I think that these include the OneForAll URC-8206, 8210, 8305, and 8308. These same remotes also have a 6 pin JP1 header that can be connected to a computer with a $30 interface cable. I don't know if the 2137 has an internal modem or a 6 pin header. Look inside the battery case for the header and your instruction book to see if it mentions the possibility of upgrading by phone.

ETA: the OneForAll URC-9960 has an internal modem, but doesn't have a 6 pin header. You can upgrade any of the OneForAll remotes I mentioned here using the modem.
