key battery

The remote sensing in the car turns off after a couple of weeks to save battery life. You have to turn the ignition on to reactivate it. Maybe that's what you're experiencing?

Mine's a 2002- 3 weeks of life for mine.
Can't be...
I'll be doing a search on defective keys. That wouldn't be good.
btw Mine's never opened either trunk, although at times I do hear some faint clicking when I press the button.

How long should the battery last anyway?

I have found that the buttons on my FOB press against other items in my pocket and was causing a drain of the battery or if near my car has set off the alarm or unarmed it. I have started making sure that I take my keys out of my pocket while sitting for long periods (at work) and make sure I have nothing else in the same pocket.

I have kept the same battery for my Lexus for two years and it is a daily driver, with the Box my battery lasted about two months prior to me changing the way I kept the key in my pocket, since then I have had the same battery for about 8 months.

Changed battery and, althought the LED flashes, I can't get any of the buttons to do what they're supposed to!
Next step?
