It appears I have an electrical problem on my 2004 Merc SL350, the 20amp fuse keeps blowing which means the central locking does not work, I have to use the key to lock / unlock the doors, but even with the key I cannot open the boot / trunk.  I have tried putting a new Fuse in but it blows straight away, can't find anything on youtube, so how do I open the boot ?  Suggesting please.


You can use the metal key to manually open the trunk.

If that doesn't work, here is another alternative.

Many thanks, the key does not work so option two it is.
