Nikon stopped selling parts to independent repair shops in 2012. Cameras, it stated in a letter announcing the policy, had become “more complex”, and required “specialized tools.”

In new letter Nikon sent to the roughly 15 Authorized Repair Stations still operating in the US, the company revealed that it would not renew agreements after March 31, 2020, meaning these repair shops would potentially no longer have access to official parts, tools, software, instruction and repair manuals, and training previously provided by Nikon. There’s still the chance these smaller repair facilities could still be provided access to official Nikon parts and other components, but they will no longer be officially considered authorized to perform these repairs. Instead, authorized service will be exclusively performed by Nikon facilities in Melville, New York, and Los Angeles, California.

Nikon is ending its authorized repair program in early 2020, likely leaving more than a dozen repair shops without access to official parts and tools, and cutting the number of places you can get your camera fixed with official parts from more than a dozen independent shops to two facilities at the ends of the U.S. That means that Nikon’s roughly 15 remaining Authorized Repair Station members are about to become non-authorized repair shops. Since Nikon decided to stop selling genuine parts to non-authorized shops back in 2012, it’s unlikely those stores will continue to have access to the specialty components, tools, software, manuals, and model training Nikon previously provided. But Nikon hasn’t clarified this, so repair shops have been left in the dark.

None of a half-dozen authorized shops we spoke with—most of whom asked not to be named, so as not to face reprisal—had heard further from Nikon after receiving their letters. While most of their repair work is out-of-warranty, most said that the loss of official Nikon parts would seriously damage their appeal to customers, who depend on their location and rapid turnaround.

Every shop owner we spoke with mentioned that Canon, while no longer offering warranty repairs through authorized shops, still sells parts at a competitive price to repair shops in good standing

“We remain committed to providing the best product support and repair services to our customers,” Nikon stated.
