New here and I did try the search function.

I have a 2007 E63

When I get in the car the cluster says Check Key Battery. Just put new ones in like two weeks ago.

Any help trying to solve this would be appreciated.

Thank You

What exactly is your problem with the keyless go? You can't lock or unlock your car?.....???
The battery might be bad?....Why don't you try changing out another battery and see if it still gives you the same message on the cluster panel.

Everything works with the Keyless, When I get in the car and hit the button on the shifter the instrument cluster tells me to Check Key Batteries, which are brand new 2 weeks ago.
Thank You

I agree... Change the battery, you might have got a bad one. Also make sure it's the correct battery with the correct voltage.

One of the batteries was put into the holder backwards. Take 'em out and put them in again. should be good to go....

That was the first thing I checked. No luck there. Afraid I will head to the stealership.

Have you tried replacing the battery yet?

Tried to get in my 2007 E63 this morning and when I pulled the door handle I got a big surprise! NOTHING!!! Got the fob out of my pocket and opened the car with it. Put the fob back in my pocket, got in and put my foot on the brake then hit the keyless start and all I got was a buzz... I believe the cluster said "No Key Present" I was parked outside where I work and the temp. was 27*. I proceeded to start the car and head for home, burned out from the graveyard shift. Pulled in my garage and shut the car off, put the fob in my coat pocket and tried to start the car w/keyless start and it fired right up. Locked and unlocked a few times and no issues. Hope this is a one time issue. I don't drive the car more than 2-3 times a week so it rarely sits outside. The batteries were replaced in both keyfobs when I bought the car by the stealer back in late January. Not sure how long the batteries will last? I will update if anything else occurs.
