A house key on the same keyring as the car key. 
The GFI cannot be ceiling mounted. It must be accessible.
A cheap, keyed mechanical release will do the trick.
You are absolutely correct. I am mistaken. A GFCI receptacle does not have to be on a dedicated circuit. Thanks for the catch on my error. No I wasn’t referring the the AHJ.
How about getting a key to the front door and keeping with you when you leave the house…works for me:)
This is the funniest post of the week by far. Is there anyway common sense could be tested prior to allowing people to purchase a home?
