Hi my mercedes c280 has been having some faults with the central locking system i have recently got the car doors open but the battery is flat , my only other problem is i cannot get to my battery because it is in the boot does anyone no how i could get my boot open without having to take it to mercedes.

Please get back to me a.s.a.p

 

Any reason that you are not using the metal key to unlock the boot if the electrical have failed?
