Key fob dead

[LTX_REAPER]

Hi Guys, wondering if anyone can assist, just bought my 525i today and the buttons on my key dont do anything, does it have a battery that i can replace or would it need to be reprogrammed, the car starts and everything

advice would be highly appreciated and if anyone knows where i can either find a new cd changer or just the cartridge/ cassette for it i would appreciate it

Thanks Guys
