There has been an increase in instances across Knox where thieves are using car key signal jamming to break into cars.

Some cars use keyless entry, which allows drivers to lock their vehicle by pressing a button on the key. Signal jamming happens when thieves use small electronic devices to block that locking signal. This can stop the car from locking properly, even though it looks and sounds like it has. Because of this, some people don’t realise their car is unlocked until they return later and find items missing — or, in rare cases, the car itself gone.

Car key signal jamming incidents are not isolated to any one neighbourhood. They can occur in shopping centres, residential streets or public car parks—places people use every day. Police say that small changes in everyday habits can significantly reduce the risk.

After locking your car, pull the handle to make sure it’s actually locked
Take valuables with you or keep them out of sight
Use a steering wheel lock if you have one, especially overnight
Park in well‑lit or busy areas when you can
Keep car keys safe at home, away from front doors and windows

These actions take only seconds and quickly become routine.

Residents are also encouraged to report suspicious behaviour, not because something is wrong, but because early information helps police respond more effectively.
