Pollensa: Opening/ Removal of Soap Dispenser

I have a soap dispenser I can't open or remove easily. It appears to be the standard fitting, looking at photos of other Pollensas. I'm wary of applying too much force in case I damage the wall to which it is attached. 

Anyone had a similar problem in the past? 

Any advice appreciated.

Thanks.

You need the white plastic key (or small electrical screwdriver) to open the lid , only turns 1/4 of a turn. Once lid is off, press lug at top and slide upwards to remove.

Many thanks Paul.....sorted!
