Hi, I took Rear Battery Out for Replacement, Well I never checked the manual Key was working to access trunk again, well with Manual Key it just truns no click or unlatch. Is there another way into trunk?

Put a bit of downward pressure on the trunk and release when you turn the key.

Ok I will go try that again. TY

I just tried even jimming the trunk up and down turning key and still no open.

Not sure but seen you tube video about another trunk problem and looks like the Key Hole button is supposed to push in when key is turned. Well mine does not push in the key turns but no button type action

Do you have two keys? If so, try the other one. Do these cars have a valet key of valet lockout somewhere?

cadbob

Yes I have the original Black FOB and I also Ordered The Chrome Key that I ordered from MB, tried both.

OMG, I got it, Thank you so much for being here. I'm such a dumb azz, Turn key and there is a little handle tucked up under the lip of the 3rd Brake Light. You turn key and squeeze Lever and she opens. But with both Batteries disconnected for over 24 hours I did not loose radio presets or Clear the white Brake message. Its like the ECU has its on memory battery
