AI agree with everything else.
Vacuum is needed to engage the diff lock, but once it is engaged it stays that way until the knob is pushed in and there is vacuum available.
It is good practice to chock at least one wheel when changing a wheel in any vehicle - best one to chock is usually the diagonally opposite one as it has most weight on it if the ground is flat. If the ground is not flat, the choice is less obvious, but try to make it the wheel carrying most weight.
