The home side had the better of the game but fell behind to Ryan Stevenson's header, before Jamie Hamill's own-goal ensured a share of the points.
Locke said: "It was a battling performance which I was really pleased about. The effort and commitment from the players was there for all to see which I felt was something that was missing last week.
"It's always difficult up here, and Jamie MacDonald has had to make two or three really good saves, which you would expect him to do at places like this, and I'm delighted with a battling 1-1 draw."
With questions remaining over whether Hearts will still be playing SPL football next season after their parent company was ruled insolvent, Locke was keen to play down the politics that surround the club.
"It's been a difficult week, but we're paid to concentrate on the football side of things. I'm just pleased we got a positive result for the travelling support," he added.
"It's out of our hands what the SPL do. That sort of thing doesn't concern me. The season is finished now and I'm glad to see the back of it to be honest, and hopefully we can now build for next season.
"I'm building the squad towards us being in the SPL next season, and until anyone tells me different that's how we'll continue. I'll be working hard with John Murray in the next couple of weeks to rebuild for next season; that's all I can do."
