You can change only the cylinder of the lock, for this you just remove the panel of the door and with the windows full at the top you can remove the fastener of the cylinder lock, that looks likey a U.
If you are removing all the handle with a different key you have drill the studs that support the door handle and then install it again with two screws with nut that you can get at Home Depot. (Is not a commercial, is because you need screws without head on one side, the used for the windows of a house)
