P.A. Parenteau also added his first goal in an Avalanche sweater midway through the third period to help the team bounce back from a season opening loss in Minnesota.
Kyle Clifford's goal in the opening period gave the Kings their first lead of the season and, given the way Jonathan Quick was playing in net, looked like it just might hold up.
But Landeskog beat Quick with a shot off a rebound early in the third. Soon after, Jones followed by sending a wrist shot over Quick's outstretched glove on a power play.
Semyon Varlamov made the lead hold up as he finished with 28 saves in front of a revved-up crowd.
