“Locks for Knocks” is a simple ambient idea, which was designed to generate immediate attention and action from drivers. We promoted a simple action, i.e. knocking on cars to alert stray cats and allowing them to escape danger. We aimed to promote this check as a “pre-driving” habit to more drivers, to encourage additional drivers to pass the “Locks” on to other cars and spread the message.

A simple gesture of knocking on the car can make the cats run away and save their lives. So, how do we stop drivers from driving away in a hurry? A car wheel lock may be the simplest way to alert and stop them.

We created “Locks for Knocks” and put them on cars parked outside to remind drivers to knock on the cars before driving. To spread the words, we encourage people to pass the locks on to more drivers. We also invited students to design their own ‘Locks’ and place them on cars in the nearby car parks.

The result was significant. Over 1,200 locks were created and circulated. More than 1,000 students from 40 schools participated in the campaign, designing over 500 locks. All the locks have been distributed and keep spreading around the city to save more lives. Moreover, this campaign has significantly increased awareness of Cats Society amongst the public.
