A burglar broke into a farm and swiped car keys from inside before driving off in a Land Rover.
The incident happened at Mattbridge Farm, Broadfield, Oswaldtwistle at around 6.40am on Thursday, December 13.
Inspector Catherine Platt said the Land Rover was worth £5000.
She added: "The occupants were in one of the back rooms and didn't hear anyone come in. Neighbours didn't see anything but the Land Rover is gone. We are appealing for anyone who can help to contact us on 101."
