Re: Still looking for an electronic lock...
I think you answered your own requirement there - a garage door opener, something that has been around for a long time and does the job it's designed for. Of course, those are still seriously lacking in security, but it does what you need in a way that doesn't require an IoT device.
You could even add your own device to it to open it across t'internet if you really wanted - plenty of Raspberry Pi / Arduino projects out there for that.
