Big_Tone,
what I think you need to do is ditch the conventional keypad and buy a web-based opener/monitoring device.
I just bought a Nexx Garage device on sale:

The thing is pretty cool, basically an electromagnetic switch on the garage door that sends a signal to a wifi enabled base that is hooked up to your garage unit.
You download the app to your smart device (iOS or Android) - you can open/close the garage door via your phone app, you know when your door is open or closed, you can enable other folks to have access to open your garage door, you can have reminders for when the door is open/closed, know when and who opened the door, and it can even automatically open the door when it senses your phone with the app installed when it comes to within 50-100 feet of the unit. (I thought have having the Homelink buttons on the mirror in our cars was cool, until the button graphics started to wear off on my M45, I vowed I was not going to let that happen again, so I bought a smaller, garage door remote to use instead) Now, I can just use my iPhone 6s plus. Hopefully the company may design functionality to have the door automatically close when it senses your phone moving away from the central unit...their website states that new functions are to come
