Stupid Smart Key
I was out with some friends this past weekend. I noticed when leaving the car in the restaurant parking lot, the car would not "flash or beep" when pushing the button on the door handle. Also, pushing the button on the "fob" did nothing. So, I lock the car with the switch on the inside and leave for dinner. We come back out later and the car would not open electrically. I had to use the key in the fob to open the door. Then the car would not start using the push button. I tried holding the key up to the button and nothing. So, I pulled the owners manual out again to be sure I was doing all of this right and after trying it over and over I finally got it to start (after about 5 minutes).
It was a little embarrassing. But, "stuff happens". I'm using my spare key for now.
Does anyone know what the life expectancy of the battery is for the fobs? Should I start stockpiling the battery's and have one in the glove box just in case...?
Also, will the car start with no battery in the fob, by holding the fob up to the button? I still have not picked up a new battery for the old one. I need to read up on how to change it and which battery to use. I am assuming this is ridiculously simple.

they last up to 3 years, but if you charge put the key near (within 3 feet of) a charging device (cell phone) or a fluorescent light it will shorten the life as the key wont go to sleep.

The battery in the fob is very easy to change. Just remove the emergency key, and use the tip of the emergency key to pry open the clam-shell case. The battery is mounted on the back-side of the circuit board, so you have to remove the circuit board to get at it. No tools needed. It takes a CR1632 battery.
The battery should last about 3 years, but can be run down prematurely if stored in an environment with lots of EMF noise. They are so cheap, though, that there really isn't a good reason to wait until it dies. Just make sure to put the old one in the recycle bin, instead of the landfill. I change mine about once a year.

Re: Stupid Smart Key
Thanks for the input. I searched and figured out how to change the battery. Thanks for posting that. I have not done it yet. 3 years is good enough for me!
I have been reading that there is a warning somewhere in the car that tells you that the battery is running low? Or maybe it was the symptoms (too many margaritas last night)?

The display screen should show "Remote Battery low" or some such message. Mine happened last December but I can't remember the message.

Hmmmm.... I never saw a warning message. It worked one minute and then it didn't. I hope the key is not damaged. I'm going to get a new battery here in a few hours and see if it still works.

Re: Stupid Smart Key
At about 3 years, I noticed the range of my fob was getting shorter and shorter (I often lock the car from the fob rather than pushing the button on the door handle). I never saw any warnings or had any real problems, but replacing my battery restored the range to as-new.

Re: Stupid Smart Key
Yup. I just replaced the battery. Took about 30 seconds. Works like new.
No warning message though. Don't really care, it was easy enough. I wish all automotive problems were this simple to fix.

It takes much less time to change the battery, than it takes to read the owners manual, think about the problem, ask this forum, or even google the issue.
I bought a card of a half dozen batteries from someone on ebay a couple years ago. They have an expiration date of something like 2018, IIRC. I just change the battery soon after the start of a new year, and don't worry about it the rest of the time.
