Anyone know of a cheap device so I don't need to put my shopping down
before
unlocking gate.

Run a search on ebay for garage door opener controls - look especially
at the Hong Kong suppliers. Put the control unit indoors and just wire
24v out to feed the unlock solenoid.

Another way would be a key pad entry system. Type the correct series of
digits in and the lock unlocks. I have one of these on my garage door,
beats searching for missing keys and going back for them when you have
forgotten them.

Clearly, what is required is voice operation!

Does he want it to operate while the wife is 500m down the road then?
