Great point cue003, I wish I had thought of that when I ordered mine! I didn't get the Key Sense option because I no longer have young drivers but now that you mention it ... Kathy and I do keep our vehicles long enough that we almost always need at least one total replacement $200-$300 FOB (lost or drowning) and about twice more per vehicle we get by with just replacing the plastic case only (transferring the circuit board over ourselves). Darn! :crying: Haha!
