Hi there i got a problem with my 1998 ls400 i only have 1 master key and the battery is starting to die i was wondering if i can change the battery in the remote or will that wipe out the chip data on it? should i just go ahead and order one of those keys that are precut using the vin and then just program it myself so i don't risk losing the data on my only working key? -sami

Thanks I appreciate the feedback I'll see if I can figure it out, I'll post results if I find any incase anyone else has similar problems.

Thanks I don't leave my headlights on auto, but i'll try turning off the dome switch hope it works. Any idea on how to track this battery draining down?

I just bought my 98 ls400 about 3 months ago and it's an absolutely fantastic car except that about a 6 weeks ago the battery started to randomly discharge. And by random I mean it'll be fine for a few weeks then i'll go to sleep one night and it just won't start. Another thing that is wierd is that sometimes it i just need to crank it 4-5 times to get it to start and sometimes no matter how many times i crank it it seems totally dead. I always make sure that all the lights are turned off before i leave it sitting. Another wierd thing is that it seems to go dead faster if I leave the stereo on when I turn it off, but if I turn the stereo off first it seems to last a little longer. This is getting to be pretty dang annoying and was hoping that one of yall might have heard something like this before. Also the battery is brand new. edit: also a tailamp failure warning came on about 5 days ago not sure if its related but all my lights work properly so not sure what thats about
