How do you program your 09 mini cooper key fob?

To program a 2009 Mini Cooper key fob, first, insert the key into the ignition and turn it to the "On" position without starting the engine. Within 10 seconds, press and hold the "Unlock" button on the key fob for about 10 seconds, then press the "Lock" button while still holding the "Unlock" button. Release both buttons, and then turn off the ignition. Test the key fob to ensure it functions properly. If issues persist, consult your vehicle's manual or a professional.
