# Parts Pairing Parts pairing (also called serialization) is the practice of cryptographically tying a component to a specific device, so that a genuine, identical replacement part will not fully work unless the manufacturer's software "authorizes" the swap. Install an authentic new screen, battery, or camera in a paired device and the [[Firmware]] may disable features, throw persistent warnings, or refuse the part outright — even though the hardware is fine. Only the maker (or an authorized shop running the maker's tools) can complete the pairing. ## Why it matters here Parts pairing is the single most technically specific battleground of the [[Right to Repair]] fight, and isolating it as its own term clarifies what the fight is actually about. The dispute is not whether parts exist — it is whether the manufacturer holds a software veto over repairs to property you own. Repair advocates (notably [[Louis Rossmann]] and iFixit) argue parts pairing has no purpose but to entrench a repair monopoly: it kills the independent-repair and salvaged-parts economy, makes [[Refurbished]] and harvested components unusable, and converts the maker's permission into a precondition for fixing your own device — a pure [[Planned Obsolescence]] mechanism dressed as quality control. Manufacturers (Apple foremost) defend it on security and safety grounds — pairing a fingerprint sensor or battery to the device, they argue, protects biometric integrity and guards against dangerous counterfeit parts. The reason this term matters legislatively: general "provide parts and manuals" laws can be neutered if pairing still bricks third-party repairs, so the most meaningful [[Right to Repair]] laws specifically target pairing. Oregon's 2024 law was the first to ban the practice for new devices, making parts pairing the line where repair legislation either has teeth or doesn't. ## See Also - [[Right to Repair]] — the movement; parts pairing is its sharpest issue - [[Firmware]] — where the pairing lock is enforced - [[Refurbished]] — the salvaged-parts economy pairing suppresses - [[Louis Rossmann]] — leading critic of the practice
