Petmate Magnetic Cat Door features a magnetic lock that opens the door flap in response to a key worn by your cat. Safe and humane way to keep out strays. Also can be manually locked in four positions; in only, out only, open and locked. Extra or replacement collar keys available.
First of all I paid an extra $8 dollars for shipping within 5 days got it in 7. Then it didn't fit by a lot. Then I had to pay to ship it back! And I still have not got my money back. *%$#
easy as pie by smiley's mom from La Luz, NM11/04/2011
Replacing the flap on the Petsafe door was simple and quick.
Just to be sure of the instructions, I went to YouTube and watched a video of a young lady demonstrating the installation. It was, indeed, "easy as pie."

I needed a replacement flap for the dog door in my slider and found this. Best price I was able to find. Shipped and received very quickly. I'm satisfied.
