Garage door repairs

Until we decide if we are actually going to keep the garage construction and fit a replacement roof..we don't wish to spend too much money on renovation, but at the same time, want to make sure the doors are secure.
We have had the builders install a new up and over garage door to the front, but rear door required some urgent repair...

 A new lock and door handle is fitted

  and a replacement piece of timber fitted into door frame
