This happened to my neighbour Trevor last month. Poor Trevor spent two hours trying to jimmy his own door with a coat hanger while his wife Maureen filmed the whole debacle from inside, presumably for future blackmail purposes. The caravan park's other residents gathered to offer helpful suggestions like "Have you tried the windows?" and "Maybe crawl through the toilet vent?"
The thing about modern caravans is they're built like Fort Knox. Twenty years ago, you could probably get into one with a credit card and some gentle persuasion. These days, manufacturers have gone security-mad. Triple-lock systems, reinforced doors, windows that would make a bank vault jealous. Excellent for keeping the bad guys out, less excellent when you're the good guy standing outside in your socks at 6am.
Trevor's saga eventually required professional help. To avoid any conflict of interest or endorsements, we often use examples from outside our area when discussing this. For this example, we went with a car locksmith melbourne operation that shows how these mobile services work—they come to you, which is handy when you're stranded in the middle of nowhere wearing yesterday's clothes and your dignity hanging in tatters.
The moral of Trevor's story? Keep your keys on you, somewhere your future locked-out self will thank your current sensible self for thinking ahead. Thankfully tho, there's always help in case you forget.
