Keyless Go Remote battery life
Thanksgiving, 2012. The GLK 350 is a year old plus a week or two. Same plans as last year. Same couple joining us. We are driving once again.
"Replace Key Battery" appears in the center of the speedometer circle. "One year, hey?" No worries. I have spare batteries at home for this purpose. The warning was early. We parked, had dinner, drove home. No worries. Changed the battery at home. Good to go.
I find it interesting that the remote battery to go first is mine. It only gets used 10%-20% of the time. My wife's remote is used most often. Go figure.
Educated guess: The new battery bought at WallyWorld will outlast the factory original.

I am very thankful that the dealer showed us how to replace the battery & we keep spares at the house. This forum has several mentions by folks who were charged $50 by dealers for a new battery. The shame!

After reading about various battery life experiences on this forum for various models, we bought a pair of batteries for $3 about 2-3 months after we got our GLK. Cheap insurance. Apparently, the Replace Battery warning appears well before the battery is dead. Don't ignore it.

A few weeks ago, I replaced the battery in my key and it lasted 3 days then the "replace key battery message" shows up again.
I replaced a 2nd battery, which also lasted 2 weeks and now I have the same error message. LOL
Time to shop for more battery.

Finally went to dealer and they said they're battery is "special". Charged us $15 but it's been fine for a couple months now. I know it's typical Dealer speak but maybe there's something we're missing. Good luck!

So next time I would try Varta, Duracell or Energizer before the dealers choise, given the price is fair.
