1. Car Key Battery for Honda Accord (2013-2017 Accord Master Key with Remote Transmitter Batteries CR1620 3V Pack of 2)
This option earned the top spot because it matches the exact OEM replacement specifications required for a 2013 fob without requiring any guesswork. I always look for precision sizing in electrical components, and this two-pack delivers the exact 3V power needed to keep your remote transmitter functioning smoothly.

But keep in mind that you must carefully pry open your specific key housing without damaging the plastic clips. In my assessment, this minor hurdle is well worth the trouble for drivers who want a dependable master key power source.

Choosing Between Them
My top recommendation is the Car Key Battery pack because it matches the exact CR1620 3V specifications required for your 2013 fob, though you should always verify your specific key type before ordering since some aftermarket fobs use different sizes. In my view, matching the correct chemistry and thickness is the only way to avoid frustrating signal drops in parking lots.
And while these button cells offer an affordable fix, you must always handle them carefully with clean tools to prevent oil transfer from your fingers. Choosing the right replacement battery ensures your keyless entry works seamlessly every single time you approach your sedan.
