keyless remote for a Xedos 9

I'm the owner of a 1995 xedos 9 in Spain. Originally, it has keyless entry remote, but the previous owner told me that it stop working properly some years ago.

Now, I've seen that in USA it's easy to find a 1995 keyless remote for about 100 dollars (at e-bay) . In Europe? I've not seen nothing like this

The question is: Does any body knows if a Millenia 1995 remote is gonig to work for a 1995 Xedos 9???

Many thanks
