I have a Mercedes C180 1998 an wonder if there is any possibillity to
open the back trunk door from the inside. Is there any button or something.
Please i need assistans.

 

no. use the key.

 

People can get confused with these locks because when you turn the key it doesn't give you the impression that it is doing anything.

The key is (no pun intended), turn the key (or unlock it) then press it in like a button. When pressing in, lightly lift up on the trunk lid as the rubber seal may be holding it down a bit.

Hope this helps.

Cheers,
