Hello,

I bought a CLK350 from a auction. The truck wont open. The truck button wont light up feels like there is no power to truck. I checked the fuse inside the car and the one in the truck by opening the soft top I was able to crawl inside the truck to check the fuse. There is a green button inside the truck when I press nothing happens no noise or anything. I still couldn't get the truck open. I don't have key blade I only have the programmed remote.

 

Open it manually:

 

I gather from your post that you might not know you have a mechanical key. It's inside the remote key fob. If you know you have it, but it is missing, then I don't know what you do.
