Erin Hatzi learned Tuesday that the key to her Subaru might not be the only one that can get the car started.

Surveillance video shows a woman opening the door to Hatzi's 2001 Subaru Impreza, starting the car and driving off.

But it was all an accident.

The woman was instructed to pick up a different red Subaru. When she realized the mistake, her friend sent the woman back with the car, a note and $30.

The note read:

"Hello, So sorry I stole your car. I sent my friend with my key to pick up my red Subaru at 7802 SE Woodstock and she came back with your car. I did not see the car until this morning and I said, 'That is not my car.' There is some cash for gas and I more than apologize for the shock and upset this must have caused you."

When the woman went to return the vehicle Wednesday morning, police caught her. The Hatzis, police and the unintentional car jacker worked things out.

"It's like my car went on an adventure overnight and, like, came back with a hilarious story and some money," Hatzi told KPTV.

Police said older Subaru keys are sometimes interchangeable.
