Sony CR2450 3V Lithium Coin Battery (5-Pack) - Long-Lasting Power for Watches, Key Fobs, Calculators & Medical Devices

Both my key fobs required battery replacement. The dealership wanted to charge me $29 to replace the battery on one key fob. I decided to look at a youtube video on how to replace the battery and which type to buy. Ordered these CR2450 3V (made by Sony - same as the original battery in the key fob) after I learned how to open the key fob and confirmed that these are the right coin batteries. I save a lot of money by changing the batteries myself (about $2.50 a battery). I tested them and happy that they work.
