An estate agent claims brazen thieves used a laptop to hack the keys to her Mercedes from outside her home before driving off in the £35,000 car.
Paige Foster was horrified to discover her partner's nearly new vehicle had disappeared from outside her home in Grays, Essex last week.
CCTV from outside her home shows two men apparently holding up a satchel containing a laptop to gain entry to the car.
In the footage, a hooded figure is seen walking round to the driver's side of the Mercedes while another holds the satchel up against the wall.
The car's door then opens and one of the pair drives it away - despite the vehicle's keys remaining on Ms Foster's kitchen table.
The 23-year-old believes the theft of her and partner Richard Haydon's car was done to order and says the incident has left her fearing for her safety.
She said: 'When I saw the video it made me feel sick - these people know where I live, they have obviously followed me or looked me up to find the car.
'The CCTV shows them walk round the back so they can't be seen by the cameras - they just pop up at my car.
'It looks like the guy up against the house has an iPad or a laptop in the leather satchel which contains the device that picks up the signal - it looks like they can decode the key to open the car.
'We have been told it's some sort of Russian military software.
'When I saw the footage I burst into tears. The fact that someone was watching me and took it not even a metre away from the front of the house is awful.'
