Replacement flaps are available as spare parts, head to our spare parts page here.

Small & Medium Essential Pet Door

1. Remove the outer frame with the flap attached
2. Remove the screws at the top of the frame securing the flap
3. Using a flat head screwdriver, pry open the metal strip/bar that clasps the flap in place
4. Position new flap in frame, push down the strip/bar to clasp the flap in place and secure with screws
5. Screw the pet door frame back in place

Large Essential Pet Door

1. Unscrew / remove the frame with the flap attached from the area it has been installed into.
2. Sit one flap hinge in place and then wedge a screwdriver between the long edge of the flap and the inner edge of the frame to expand the frame enough for the other hinge to slot back in.
3. Please note when leveraging the flap in and out of the hinge hole it does require some force but as the plastic flap is slightly flexible, it should be able to take the pressure.
