I'm getting a couple of extra smart keys from Yahoo Japan and just need to know if the 2004 LS430 facelift fob will work on a 2001 ?

 

I highly doubt it. Usually you have to look at the FCC iD and make sure they match

 

Yeah it won't work, but - you can get a replacement fob hou

sing that looks better than the honda Civic style button key. you graft your button innards and the key blade to a flip style housing. It's like $15 on Amazon.
