Hey fam I’m having a issue with my 2006 is250. The changed the key fob key last night because the the issue started a couple of days ago. One day last week when I was trying to start the car the “key not detected” message popped up on cluster, that’s what made me think the battery was going out. That’s the only time it showed up on the dashboard. But fast forward back today, I unlocked my car using the fob and got in and depressed the brake pedal. The push start lights up green. Push and nothing the dash took a little to light up and the button is orange now when I take my foot off of the brake. I don’t know where to begin to look. I know the starter, starter and alternator are good. Below I added a few videos. Hopefully y’all can help guide me in the right direction. PS, this is my only key

Hold the keyfob right near the push button and try to start it

 

When you said you replaced the key, means you used the other key fob (spare)?

Could be your remote batteries are low on battery power or outright dead. Replace the battery and try it, Good luck.

The chances that your key fob has lost the program is quite low.
