Thought it interesting that my MID flashed on this evening telling me that the remote batter needed changing. I appreciated the warning and just posted this for everyone's info. My car is 3 years old in November so the battery lifespan was decent. Part number CR2032 for those interested.

 

make sure you get a good replacement (enegizer, duralast...) The 2nd tier replacement batteries do not work well in our remotes.

 

Got the Energizer - 6 bucks at a local Walgreens. Replacement very easy.

 

I agree. A friend of mine had an extra battery. I popped it in and 3 weeks later, I got the notification to replace battery. I ended up stopping by the local dealership and picked one up for $6. No issues ever since. And yes, my first battery lasted 3 years.
