Try 0000. No bs, this is the default passkey for alot of bluetooth hookups.

BMW bluetooth factory key is 00000 or 11111 if you have the optional Bluetooth BMW x5 radio didn't have bluetooth 10 years ago it was optional in 2004
in case there is no bluetooth installed in the vehicle this is the kit we use on BMW radios
