*Replacement flaps come with two sets of hole plugs, but you will only need to use one on your flap. For your door, use the set of 8 large hole plugs and discard the set of 4 smaller hole plugs.

Step 1 Remove the Hole Plugs

First remove the Endura Flap from the door or wall.
To do this, you will need to remove the hole plugs. Don't worry, we sent you some extra ones!
You can drill a hole in each plug and wiggle the plug out with a screwdriver to pull them off.

Step 2 Unscrew the Frame

Use the Phillips head screwdriver to remove the screws that were under the hole plugs from the frame then remove the entire flap assembly from the door or wall.
Carefully bend the tabs holding the tunnel together upwards until horizontal, then remove the long side pieces of the tunnel by sliding them off of the flattened tabs.
You can use the flathead screwdriver to get it started. Careful! The tabs may snap off if bent too much.

Step 3 Remove Retainer Ring

Look for a metal rod at the top of the flap frame—remove one of the circular metal retaining rings by forcing it off with a flathead screwdriver.
You only need to remove one retainer ring.

Step 4 Remove the Rod

Push the metal rod through the flap frame until it comes out on the other side.
Pull the rod out and remove the flap.

Step 5 Expand the Bellows

Position the new flap in place in the frame and make sure the magnets are attracting correctly. If they are not, try flipping the flap around (switching the interior and exterior faces).
Sometimes the bellows (accordion-like sides of the flap) contract during shipping and prevent the magnets from attracting. To fix this, remove the pivot washers from the top corners of the flap and use a blow dryer to lightly heat the bellows and stretch them back out.

Step 6 Check the Magnets

Before installing your new flap you should check to make sure that the magnets in the flap and the frame are attracting correctly.
If they seem to be repelling, you probably need to flip the flap around so they work properly.

Step 7 Position the New Flap

Guide the metal rod back through the flap and frame.

Step 8 Install Retainer Ring

Push a new retainer ring on by holding the other side of the rod in place while pushing the ring on with your fingers.
Each side only needs one ring, and the teeth need to be bent facing away from the flap. If you’re having difficulties putting the new ring on, try flipping the ring around so the teeth are facing the opposite direction.

Step 9 Re-Install the Pet Door

Reinstall the flap assembly into the door, wall, or panel. Line the holes up so you can see light through them, then screw them into place.
Do not overtighten.
Install the new hole plugs using a rubber mallet or another non-metal tool such as a hammer and wood.
Use the set of 8 large hole plugs only. Discard the set of 4 smaller hole plugs.
