Need a battery for your car remote? Here’s a good deal for batteries at $4.06 on Amazon and ship for free with Amazon Prime! They are the Energizer CR2032. At least twice a year, I am scrambling to find a battery for my remote. Like I am too lazy to just lock the car from the inside. So grab 2 or 3 packs to keep around the house. I have 2 cars that need them!
