have an 02 td4 freelander and only have 1 key and no remote key fob. i've been looking on eBay and seen a few key fobs going cheep. will any key fob do like say an old 214 or 200 400 series etc. or do i have to get a certain 1. also have i to take to main dealer to get programed or can it be done by a certain method myself. also another key would be great but main dealer is very expensive. i was quoted around £170ish for another key and a key fob and programed.
