Being locked out is stressful, but a few sensible steps can save you time, money, and unnecessary damage to your door.
First, check for any other accessible entry point you can safely use, such as a back door or a window you have left unlocked. Never attempt to force a door or window open, as this can cause expensive damage.
If you have a trusted neighbour or family member holding a spare key, that is always the fastest option. If not, call a locksmith who offers non-destructive entry - this means gaining access without damaging the lock or the door itself.
Always ask for identification before letting anyone in, and get a rough price over the phone before they arrive so there are no surprises.
Once you are back inside, it is worth considering whether it is time to cut a spare key and leave it with someone you trust nearby.
