Keyless car key pouches have been handed out by police across Bucks amid a spike in car thefts.

The apparent high-tech system of keyless car entry actually just relies on radio waves - so criminals can very simply trick it to steal vehicles.

Police in Wycombe, Chiltern and South Bucks say there has been an increase in criminals being able to steal keyless cars, so officers have been handing out signal-blocking pouches.

Officers in Wycombe said: "The PCSOs have given out 70 of these pouches across High Wycombe, Marlow, Princes Risborough and Hazlemere.

"We still have plenty more to get through so expect to see us out and about in the next few weeks."

And TVP Chiltern and South Bucks said: "There have been a number of Keyless theft of cars in Beaconsfield recently.

"Officers have distributed signal blocking pouches to addresses with keyless cars parked out front.

"Please make sure to keep car keys away from doors and if possible in a signal blocking pouch."
