I have not had any issues with mine. I have not needed to change them. I barely use it. I use the tab on the door to open the doors most of the time. Glad to know there's a DIY on this.
Doesn't matter how you open the door, the car reads the signal/battery strength once inside. If you are not getting the indicator, your battery is still OK. That is a very common battery size so you can get one just about anywhere that sells batteries.

I think he's trying to say battery life in the ikey is longer becasue he "barely uses" the ikey's buttons. The transmitter in the ikey uses more battery power than the RFID by itself.
