Nissan Micra (Muzic) 1997 car. Does this car come with a remote or something else

[rose b]

to program key code? bought nissan micra (muzic) car. It had been sitting for 2yrs no driving just the engine been turned over. She drove ok for one day however the 2nd day she completely powered down. So we put a new alternator and battery in, still no joy. Mechanic said we needed key recoded immobliser had kicked in. Problem is the car came with one key no manual no code. Does anyone know did this car have a remote or something else to reprogram key code? thanks Rosie
