E46 M3 Spare key not working

[Navin]

Hi guys

Is there any way i can get the spare fixed or do i have to buy a new 1?

Any ideas on how much it will cost and the procedure in doing so..?

It's just the buttons that don't work

The battery could be flat. If you haven't use it for a while, unlock the car with your normal key and start with the spare key and take a short drive. Then check if the buttons work - if they work, then it's just the battery that needed charging.

The key might just need reprogramming.

The ignition charges it, just use it for a few hours to see if that help.
