Anyone got this problem, please post your feed back
Thank you very much

 

Have you tried your other key? How old are the batteries in the keys.

 

I replaced battery 2 to 3 mths ago, and it's happen around that time. After I replace baterry, it's blinking more than 10 times when Everytime I got in the Benz and leave the key in cup holder
I dont remember I've try the other key.
Problem after problem that make me really want to trade in for BMW X5 5.0, even though my ML just hit 20,000 mls.

 

2011 ML with 20K miles, sounds like a dealer warranty issue?
Take it to MB, get a loaner and go back when they say it's fixed.

 

Warranty or no warranty, Dealer is the most capable place to have this taken care of. OP says it began when he changed the key batteries, could be he damaged something opening up the key.

 

as well............I replaced my battery after 11 months and a month later, the message came up that I had to replace the battery again.........So I replaced it with a better brand battery............(CR 2025)

 

Sounds like you ended up with bad battery in your key.

I have gone back to buying my batteries from the MB dealer for keys - I tried various others (well, cheap ones) and they didnt work for long.

I suppose I could buy Varta ones from somewhere else of course, but batteries at MB arent expensive.

Brought to dealer, technician said Botha remote key fobs are bad, ordered new key fobs take 2-3 days.
