Wether it's open or closed, a couple of these (top and bottom) of the door are a good way of adding extra security for wood, pvc and aluminium framed doors. A locksmith would likely have to order parts for the lock, so probably end up fitting these in the meantime.
Has it failed open or locked closed?

If it's open and the sliding leaf is on the inside, wedging a length of broom handle to prevent it from sliding is a quick temporary measure.
