You can buy an electronic lock at most hardware stores that would work.

Checked my lease and it allowed me to provide notices electronically as well as through mail.

@Amadeus HladunDepending on the province there will be a provincial land registry which you can access electronically or physically - frequently for a small fee.  

I would be concerned that an electronically translated lease would modify the legality of clauses through incomplete or incorrect meaning.

I believe this industry is geared to go global and electronic.

I’ve found that to be true with contractors and electronics.

Is it that the electronic temperature selector won't go any higher, or is it that they're using some kind of thermometer?

We are both physically located in the northern suburbs of Atlanta but do everything electronically so location isn't very important. 

I just went through this for a property I bought out of state and it’s pretty simple.Make sure the agent knows the new owner is out of state and they will be able to do most of it electronically, they will also send a notary to to wherever the new owner chooses.,,, in my case I just had them come to my office on my lunch break and it took about 35 minutes to sign the docs, fingerprint etc. 

This is phishing with an IQ.These emails are designed to electronically hijack the homebuying process at the most critical moment, just before closing.
