i bought my SC from some guy in Jersey and he gave me 4 keys. 3 of them have the remote button. noone of them worked at the time, i figured it was just the batteries, i bought new batteries at $4 a peice, and still nothing. also checked the ON/OFF button for the remote entry under the steering wheel, its not that.

 

noone had this problem???

 

I'm having the same problem with my LS 400. I found what might be a fix for me in the LS 400 forum. You should try the forum for your vehicle.
