I needed to install two doggie doors, one from the house to the garage and the other from the garage to outside. Both doors were metal. I installed the first door and discovered how to do it. This video shows how I installed the doggie door in the metal door from my kitchen to the garage.

The doggie door I used I purchased on Amazon. https://amzn.to/2MCTpxB
This instructional video was made specifically for this product, but it's highly likely that the installation is similar to most brands.

I used jigsaw blades with the T Shank Design. I purchased a package of blades similar to this one on Amazon. https://amzn.to/3njCvRb
