While this may seem like just another thing that’s added to your plate, make copies of all of the keys prior to you move. In all of the chaos of the move it would be easy to lose a key, and that is the last thing you want to deal with on your moving day.
If your friends are helping you you move then be sure to get them some drinks.
Put pads or blankets on the floor when moving large furniture. This will make sure that you do not damage the floors during the move.
