My guess is either they are all the wrong ones, or all the batteries are dead (possible). 2006-2009 uses same sensor (433 Mhz). Rather than paying somebody to diagnose, ti would be better to just get replacements and change them all. Best price I've seen is $168/4 (without valves - reuse existing) from The Tire Rack. Then you'd need to pay about $100 for dismount/mount/balance> At least you'd know you'll have something that works for the next few years.

This is another option, though I don't know anything about it: http://www.turnermotorsport.com/p-22...-e88-2007.aspx.
