Just found out that we lost all but one of the keys for my wife's wagon in our last move. Last time I bought a key on ebay, they were around $10 or $20. Now they are $50. Not sure why they went up so much in two years. Are there any other sources besides ebay? Also, will the 3 button remore work on a wagon? The two button are difficult to find. The non oval button type won't work on a 2000, right?
