So I get in the car a couple days ago and the alert on the dash says that I need to replace the key bettery. Is this an MB item or can I get it anywhere?

Thanks.

 

You can get it anywhere, I recently purchased the batteries at Radio Shack. Don't get a stealer unless you want to get raped.

 

Radio Shack, when you take the valet key out use the same key to push the plack pin down and separate the FOB, you will able to see the battery.

Good luck, any questions PM I'll send you pics on how to do it.

Happy Thanksgiving!

I had this come up in my dash and end result it was something else all together, another problem and not just the bats, does it seam odd that they need to be replaced? like has it not been long?

 

I will try to get it out this week. Too much work last week.

Intellilogic.... What was the final result? Is that a VW Vanigon next door???

 

My battery is LOW too..must be that time of the year!!

 

Had to get the book out to figure out how to take apart the key fab for the battery replacement. The plastic verus the chrome come apart differently.

Good thing the Traumadoc is a doc--put his skills to good use for the removal of this organ.

 

I had the batt replaced by the dealer for $20.....didn't know you could do it yourself. Next time, I guess....

 

I've had to replace mine 2X; it's a complete PIA to open that damn "smart"key and replace the batteries!! but even after replacing both the batteries the smartkey recognition sensor intermittently refuses to recoginze the key. Then I wave the darn key in front of the dashboard and it sez "ya, OK, you da man." Jeez Louise!

 

I had the same thing come up on my dashboard. I'll replace mine tomorrow. I'll try to snap some picks. lol

 

Just tried it and opening it was a snap.

My Service Advisor replaced the "fob key" battery for me free of charge

It pays to take good care of your Service Advisor ..
