Hartal Magnetic Door Retainer Removal?

[Michael.]

Morning all, I am trying to remove the plastic cover on a magnetic retainer, I've used a flat blade screwdriver in the small holes but there is obviously a knackered to it, thought I'd ask on here before I break it Cheers

I think the slots on the side give access to a clip on each side that clicks into a slot on the backplate.

A gentle straight push in with your small flat screwdriver should push the clips back inwards and allow the faceplate to pull up off.
