msrdude Posted March 15, 2011 Share Posted March 15, 2011 I have a 99 Lexus GS400 and the remote does not lock, unlock the doors, and the trunk release. The red light does not come on when I press the button. I replaced the battery and it worked, but only for 2 or 3 days. I replaced the battery again, and it still does not work and the red light does not come on. Anyone know what is wrong and/or know how to fix it? I think its a connection problem where the lithium battery and the metal thing connects but not sure. Quote Link to comment Share on other sites More sharing options...

If that does not fix the problem then i believe you need a new master key. they go for roughly 140-170$ new. Quote Link to comment Share on other sites More sharing options...
