Spare Key Fob Not Working

[willy_manily]

Hi there,

Just found my spare key for my X5. It works in the ignition and doors but the unlock and lock buttons don't work.

The key has never been used so i don't believe it would be damaged. From what I understand the key self charges when it is inside the ignition, however i've been using it for about a week and it still isn't working.

Has anybody had this issue before? Is it possible to change the battery inside the key?

Regards

Look up the re-initilzied procedure.You need to do both keys at once when you do the process.
