Keyless entries might be very convenient for some drivers, but it made a $15,000 heist for a thief in Sausalito much easier and more discreet.

On Thursday, a man in Sausalito was able to hack the keyless entry of Sarah Piampiano's Audi parked on Central Avenue and get away with her livelihood. Piampiano is a triathlete, and inside her car was a custom-made, $15,000 bike by Cervelo. "The way he got into the car and got the bike out, he just knew exactly what he was doing," she told ABC 7.

"It is believed he used an unknown type of electronic device or remote to open the car doors electronically," said Sergeant Bill Frass of the Sausalito Police Department. The thief, who was caught in the act on surveillance camera, was able to break into so effortlessly that a neighbor of Piampiano's witnessed the theft happening but assumed he was the owner of the car. In addition to the bike, the thief also made away with a suitcase in her car. "If there's value, do not leave it in your car, take it with you," warned Sgt. Frass.

Piampiano will get a replacement from her sponsor, but she says it's not about the bike, but the principle. "More than anything, I want to be able to catch this guy," she said.
