I have a 9/91 525, but its a 92 model year. I am not sure whether or not it will be ready for keyless entry. I am looking at this:

http://bmwalarm.vstore.ca/product_in...products_id/64

and says "This is a complete plug-n-play keyless entry system built for your pre-wired** E34 5-Series BMW (1992-1996)"

But I am not sure what's up or how to know for sure. Any help?
