Something to consider if you place two or more fobs on the same counter or same pocket or same purse routinely. They are tiny radios and constantly transmitting and receiving. It won't hurt them but doing this repeatedly will decrease your batteries at a much higher rate as their constantly talking to one another by trying to communicate and failing.
I keep mine at least 10 feet or more apart as a general rule.

Just a note about alkaline batteries. They don't die gradually like the old-style. They maintain their voltage until they reach end-of-life, then the voltage falls off rapidly. This is why some batteries will be good enough one day, then not good enough the next, and so on. Our fobs lasted three years then died suddenly. Hope this helps in this application as well as others.

I got the "change your battery" warning and did so. No more alert. Then two days later I get the alert again. Then no alert for a week. Then alert again. Then nothing.
I finally realized I was getting the alert whenever my wife was with me... with HER fob in her purse. Changed the battery in that... and no more alerts!

Be certain you are not leaving the fob(s) in the car while parked, even in your locked garage.
Not sure if the fobs "talk" to each other but the fob battery life is definitely shortened when they
are within three (3) feet of the car.
