From Germany to the Northern Beaches
Andreas Weinert, Andy to everyone here, migrated from Germany to the Northern Beaches and founded Ali Ba Ba Lockmasters & Security Specialists in 1996. The company behind it, Ali Ba Ba Security Pty Ltd, followed in 1997.
Today the work covers alarms, cameras, smart home systems, intercoms, locks and safes. One thing is the same as in 1996. You call Andy, and Andy turns up.
Over the years that has added up to more than 3,500 repeat customers from Mosman to Palm Beach.
“Our greatest compliment is when parents recommend us for their first-home-buyer children.”
Why Alibaba?
Open sesame.
In the Arabian Nights, forty thieves hide their treasure in a cave that opens to two words. Ali Baba, a poor woodcutter, overhears them, waits until they ride off and says the words himself. The cave opens.
A password anyone can overhear is the oldest security flaw there is. Andy took the name of the man who walked straight in, and has spent every year since 1996 keeping the forty thieves out.
Security should be simple
That is Andy’s motto. A system you find fiddly is a system you stop using.
-
Built around how you live
Andy plans the system around your household, your routine and your budget, so you use it every day and don’t switch it off after a week.
-
One visit, many jobs
Andy services, repairs and updates alarms, cameras, locks, intercoms and gates in the same visit, whether it’s a letterbox key or a whole alarm system.
-
A fixed price before work starts
Andy inspects the site, or you text him photos. Either way you get a fixed price.
-
Pet friendly, too
Dogs and cats are part of the household. Tell Andy who lives with you and he plans the system around them.
From Mosman to Palm Beach
Andy works across the Northern Beaches and the lower North Shore of Sydney, from his base in Mona Vale.
He also looks after holiday houses with back-to-base alarms for owners who live overseas or over the bridge, and property portfolios for local real estate agents.
