Take a voltmeter and check for voltage at the switch, if you have it work your way back til you find the problem. It could be fuse, switch, actuator or bad wiring connection.

Yeah I can only open it from the key - electronics wont work

new battery in the fob maybe?
reprogram the fob?

The word fob may be linked to the low German dialect for the word Fuppe, meaning "pocket", however, the real origin of the word is unknown.  

found this searching around.
