Parts Pairing: How Apple, Samsung, Microsoft, and John Deere Lock Out Independent Repair

What Parts Pairing Does

iFixit has compiled multiple documented cases of "parts pairing" — software systems that recognize a component's unique serial number and disable features or trigger persistent warnings if a part is swapped, even when the replacement is a genuine, identical part from the same manufacturer.

On Apple iPhones, installing a genuine Apple battery taken from another iPhone triggers a warning that the battery cannot be verified as genuine, a message that can reappear for days. On the iPhone 13, replacing the display with any unauthorized part — including a genuine one — disabled Face ID, even though that model's display is not physically connected to the Face ID sensor hardware. Apple has fixed some of these issues after public criticism, but the pattern has recurred across product generations.

Similar behavior has been documented at other companies. In 2021, YouTuber Hugh Jeffreys showed that swapping genuine parts between two Samsung Galaxy A51 phones disabled fingerprint scanning until an older software version was restored. Samsung told iFixit it does not require parts pairing on its smartphones and that a correctly performed repair should not cause functionality loss, though it did not explain the specific incident.

Microsoft has confirmed that the Xbox One's optical disk drive and motherboard are factory-paired as an anti-piracy measure, meaning a broken disk drive cannot be replaced with a working one from another console. Microsoft does not sell replacement drives itself, leaving the secondhand market as the only option.

In agriculture, John Deere equipment can enter a restrictive "limp mode" after certain malfunctions. The diagnostic and repair software needed to clear these errors is not publicly available, forcing farmers to wait for authorized Deere technicians.

Industry Pushback on Repair Legislation

During Nevada legislative proceedings, a lobbyist representing OEMs including Google, Samsung, and Apple argued that repairs should be limited to approved technicians using genuine parts, citing consumer security concerns about unvetted third parties.

Apple's Independent Repair Provider program, intended to let outside shops access genuine parts, requires participating shops to share customers' personal information, restrict which repairs and parts they use, and submit to audits for up to five years after leaving the program, according to a contract reviewed by Vice.
