I put new batteries in my key fob and I still don’t have as much range as I use to.

Whenever you purchase batteries for your fobs we always recommend taking a multi-meter and testing the batteries to ensure they are 3.0Volts. The CR2032 is a popular battery however it is not as popular as say a AA battery, this means they tend to sit on the store shelf/stock room/ware house etc for longer periods of time.
