TrolKey was invented to overcome a common problem of not having the correct change to unlock a shopping trolley when going shopping. “It was while my wife, Sophia, was pregnant, I volunteered to do the weekly shopping, But I quickly realised that some supermarkets needed a €1 coin for their trolleys while others required a €2 coin, neither of which I usually had.
I also regularly saw that I wasn’t the only person, people are queuing up to ask for change at cashiers more and more often. This frustration led to me developing TrolKey.
After initial trials I questioned whether it was possible to unlock the trolley with a ‘trolley key’ that could be removed from the lock so that you could leave it on your key ring, It was!
TrolKey does exactly that!
Being a Design Engineer with a creative flare, I wanted TrolKey to be functional but also look good on your key ring”.
With the help of family, friends, and of course, Gavin from Dragons’ Den TrolKey is now available to everyone.
