I have the one button key/remote. It isn't working so I want to change the battery. I have made few attempts at opening it but I'm afraid to put to much pressure on the plastic case. Any suggestions?
Is it even designed to be opened?

Your key like this?

 

Slide, not sure what you mean? That thread isn't about keys

 

I'm an idiot. Here is the real one. https://www.clublexus.com/forums/ls4...lexus-key.html
Once again, is your key like this? lol

 

Yes! Thanks a ton.

Update. Just so you don't think I'm a total idiot. Looks like the previous owner did a replacement. He did not replace the screw or the O-ring. He also glued it shut. I took a razor blade and went around the seem then it popped right open.

Will I need to go through some reprogramming process?
