Jamming is being executed by professional gangs and motorists need to remain vigilant to prevent falling victim to this scam. Criminals can block vehicle and/or garage door remote-locking signals by using a device that operates on the same frequency.
"TAKE THE FOLLOWING PRECAUTIONS"
Don't walk away from car unless you have heard/seen it lock.
Physically check that your doors and boot are locked.
Lock away all your valuables so that they are not visible.
Visible securtiy measures such as gear-lever or steering-wheel lock may deter thieves.
Also Check your insurance policy as most policies will not cover property stolen from your vehicle if there was no forced entry and other policies only cover goods that were locked in the boot.
