Ok, I bought a five pack.

I will be using 2 right off the bat and keep 1 in my glove box.

Who wants 2 for themselves for 1 dollar? (shipping)

 

I routinely change the batteries in my main remote and the back up once a year. I go to the dealer's parts dept where they change them for nothing while I wait. Yes, I have to pay for the batteries but not much considering what we pay for these cars. Also, ask to see the expiration date on the batteries that the dealer is putting in your remotes - certainly don't want to get a battery that's been sitting in a parts place somewhere for a long, long time.
