Police are warning owners of high-powered vehicles to ensure their homes are secured and keys are hidden away after an increase in burglaries.
Officers believe thieves are mainly targeting addresses with top of the range Audis, VWs and BMW on the drive, looking to steal keys and then the vehicle.
DI Richard Monk said: “In the last two weeks, since the clocks have gone back and the nights drawn in, we have seen an increase in the number of car key burglaries.
“As security on cars increases with the addition of immobilisers and trackers, criminals need keys to drive vehicles away. They break into a property in the hope that keys will be on view and easily accessible.
“We have seen patio doors being forced, and in one or two cases, an offender has just been able to open an unlocked door and walk inside.
“People invest thousands of pounds into their vehicles, and we want to make sure everyone is aware of this latest trend so they can take steps to protect their property.”
Security measures such as setting a burglar alarm on the ground floor, hiding keys or taking them upstairs, ensuring vehicles and property doors and windows are locked, and remaining vigilant while reporting anything suspicious, can help reduce crime.
Anyone with any information about those committing car key burglaries is asked to contact Nottinghamshire Police on 101 or Crimestoppers on 0800 555 111.
