I just bought a 9 year old Razor scooter at a thrift store for my grandson and it has the same problem with folding. The latch behind the wheel moves BOTH directions. The key is that the latch easily moves one direction but requires the movement of the bar to move the opposite direction. If you wiggle the handlebars forward and backward while working the latch lever you will find that it eventually clicks and releases. When you figure this out you can use the orientation of the scooter to assist you to fold it up quickly.
