Brunswick police are investigating after a theft on 24 December last year, Victoria Police say.
Police have been told the victim left his car keys and a pair of boots on the ground outside his Barkley Street address and walked away from the front gate for about 1 minute.
He returned to find his boots still on the ground but his car keys were missing.
A review of CCTV shows images of a woman who may be able to assist police with their enquiries.
The woman is perceived to be Caucasian in appearance, blonde hair with a medium build and she was wearing a black shirt with black running pants.
Anyone with information is urged to contact Crime Stoppers.
