my remote key stopped working i have 2002 sc430 nothing works lock/unlock/trunk.
Any suggestions Many thanks

 

Most likely your key battery is dead. If you have a spare key, that'll probably still work. Pick up a battery at Radio Shack, etc and replace the one in your key. I think the replacement procedure is in your manual, but here's a link...

YW.
