You will need to separate the back and front case of the actual key at the top along the line with a thin device. It snaps apart and back together. In you will find 2 batteries.

The MB 320 engine has NO dipstick! Oil level is monitored and shown on the digital portion of the dash instruments.
First, try to warm the key a bit. If the battery inside the key is poor, this will help. Second, try holding the key close to the left corner of the front window and try to open the car. If this doesn't work, call your MB-dealer.
You don't say what year your vehicle is and I am not sure if it is the same on all MB models and years but here is the procedure for my 2002 C320. Maybe it is the same for your year/model. You pull the metal key out of the FOB then use it to push in the grey tab that you will see when you look down the channel that the key came from. While you are pushing in that grey tab you pull up on the top part of the FOB separating it from the rest of the housing. Do not force it! It should come out easy at this point. You will now see the two CR2025 batteries that have to be replaced. Replace them both and slide the battery/circuit board back into the housing and put the metal key back in. It was amazing how you don't even realize how weak the signal was until you replace the batteries.
