firsttimelexus Posted October 30, 2007 Share Posted October 30, 2007 Does anyone know how to replace a dead battery in a 2005 LS430 Key Fob? I'm a DIY'er and would love to learn and not have to possibly pay the dealer to do a simple switch of a new battery. Thanks. Quote Link to comment Share on other sites More sharing options...
wickedgt Posted October 30, 2007 Share Posted October 30, 2007 If it's the same as my 2001 key (which I believe it is) just get a small phillips screw driver, split the halves, pop the battery out, go to walmart jewelry dept. and purchase battery. It was pretty simple, no reprogramming required. Hope this helps. Quote Link to comment Share on other sites More sharing options...
