John Gibson made 30 saves for the Ducks (13-22-0), who have lost three of their last four games.
The Coyotes played a complete game from start-to-finish, outshooting the Ducks 32-28 and finishing 1-for-3 on the power play while killing off all three penalties they took.
Ingram dazzled early and often, earning his third shutout in the month of December and the fifth of his career.
"There was not a lot I didn't see, so that's huge," Ingram said. "When you see it, you're probably going to stop it. I think we did a great job of that and got it done."
Keller opened the scoring with a power-play goal at 7:38 of the first period, one-timing a pass from Nick Schmaltz past Gibson. The 25-year-old now has six points, including four goals, over his last six games.
Crouse made it 2-0 at 10:05 of the second period with his team-leading 16th goal, one-timing a pass from Matias Maccelli past Gibson, and Ingram shut the door from there.
"Every game counts, especially this time of the year," Maccelli said. "It was a great game for us, I think. We played really solid today and got the job done."
Ingram improved to 13-7-0 on the season, earning his first win since a 1-0 shutout over the San Jose Sharks on Dec. 15. He had allowed seven goals over his previous two starts, but shined throughout the game on Friday to help the Coyotes close out 2023 on a high note.
"That's Connor," Tourigny said. "He's strong mentally, and he's a really good goalie."
As the calendar flips to 2024, Ingram said both he and fellow netminder Karel Vejmelka are preparing to help the team continue to play in meaningul games.
"We're just trying to get better," he said. "Whether it's [Vejmelka] or me, I think both of us are going to go in there and give us a chance."
