A neighbor has a DoorKing gate where she wants to change the code.

Looks like a Model 4302-111 from DoorKing, Inglewood California.

Can't find the darn right manual at http://www.doorking.com/tech because
that part number is for the "control box", and not the gate stuff I guess.

For example, this is close (maybe)?

They're closed now, so I will call 800-826-7493 tomorrow (Email:
) but offhand, anyone here have a DoorKing gate
know how to re-program it?
