Lynda Greenwood had bright pink house keys so she could find them quickly to get inside in case her violent ex-partner was waiting to ambush her.
But they were no help just after midnight on October 20, 2020, when Jason Lloyd bludgeoned and stabbed her to death as she walked to her front door.
In the NSW Supreme Court on Friday, Justice Geoffrey Bellew jailed him for 25 years and six months with a non-parole period of 19 years and one month.
