after replacing the battery the remote is not working. How do I set it up?
Hi, Do you mean the main battery in the car? If so, here is a link which may be of some help, in reprogramming the key to the car. Try methods 1 and 3. http://www.programyourkeys.com/BMW_Z3_Ke… If you mean the battery in the key itself, have you inserted the battery in the correct way?
