Remote fob part no for 2003 civic 1.4 imagine
 

Hi just purchased a 2003 civic 1.4 Imagine with no remote fob. I guess lost or by previous owner.
I would like to get a replacement but have no idea what the part no/ frequency should be as I understand I can reprogram any fob as long as its the correct one. Researching there is more than one "two button fob" and they look identical but are different internally. Any help appreciated or if someone has a UK registered civic of that era can pass on the part no/ frequency details from their fob would be great.
