Hi Guys Hope you can help me well my daughter actually she could not open her car this morning with the usual key fob so she has had to use the spare key, my thoughts are that the battery has gone in the first fob, now my question is can I change the battery or do I have to take the car to the local BMW dealer for them to replace and re-code ? The car is a 57 plate mini 1 ME32 with the LARGE round three button key Many Thanks in anticipation Alan n.b This is the second time I have posted this thread as I could not find my first thread, have I done it wrong is there an electrical section the thread has gone to or am I thick. If two threads appear I am thick !!!
