Ls400 Key Alarm

[SalVage]

On my master key for my Lexus LS400 theres a button on the side of the key. im guessing its for the alarm and to auto lock and unlock the car. i just replaced the battery and i tried it on the car and nothing happens. can anyone confirm that its for the alarm and if anyone knows how much it costs to get a new key for it.

Hi,

Look to the left of the steering wheel there is a panel just below with a switch on it that says remote make sure it is switched to on or the remote will not work.

Cheers,

mine doesn't work either. i didn't try the switch yet, but i think i still should replace the battery because i don't even know when it was last replaced. do i need to go to the lexus dealer (toyota) to replace it?
