Seattle police say it's thanks to technology that it caught a suspected car thief.
That man, an unidentified 38-year-old, took a BMW from a parking garage after finding a keyfob inside, a police web posting said.
Once he was able to start the vehicle, he drove it to another area of town, then fell asleep inside.
When the car's owner discovered his car was gone, he called 911. Police officers then called BMW, who tracked the vehicle's location.
BMW employees were able to remotely lock the car's doors, trapping the suspect inside, "presumably while hissing something terrifying like 'I'm not locked in here with you, you're locked in here with me' into the car's sound system," wrote Seattle police on the posting.
The man was arrested and charged with auto theft and drug possession.
