You own your car. You own your tractor. You own your smartphone. But increasingly, software repair locks determine whether you can actually fix them. Manufacturers have found a loophole in the growing right-to-repairA legislative and consumer movement that asserts the legal right to repair and modify equipment and devices that people own, including access to repair documentation, spare parts, and the removal of software-based restrictions that prevent independent repair. movement: even as states pass laws requiring access to parts and manuals, digital barriers prevent replacement components from working unless the manufacturer authorizes the repair[s].
The consequences are measurable. Auto repair costs have increased 44% over the past five years, 1.8 times the rate of inflation[s]. Over half of mechanics report passing as many as five repairs per month to dealerships because they lack access to the data needed to complete the work[s]. The right-to-repair movement has achieved significant legislative victories, but manufacturers are staying one step ahead through technology.
How Software Repair Locks Work
The primary mechanism is called “parts pairingA hardware restriction that prevents a device from functioning normally when a component is replaced with a non-original part, often enforced through software verification that detects third-party components and disables features or displays warnings..” When you replace a component like a battery, screen, or sensor, the device’s software checks whether the new part has been registered by the manufacturer. If it hasn’t, the device displays error messages, disables features, or refuses to function properly. The part itself may be identical and genuine, but without manufacturer authorization, it’s treated as counterfeit[s].
In vehicles, manufacturers have taken this further with telematicsA wireless system in vehicles that collects and transmits diagnostic data and performance metrics to the manufacturer or service provider in real time.: wireless systems that transmit diagnostic data from your car to the manufacturer. When your check engine light comes on, the manufacturer knows before you do. They can contact you directly, steer you to authorized dealerships, and in some cases perform remote repairs that independent shops cannot replicate[s]. Independent mechanics, locked out of this data stream, are left diagnosing problems blind.
The John Deere Case
No company illustrates the problem better than John Deere. The Federal Trade Commission sued the agricultural equipment giant in January 2025, alleging that Deere maintained a 100% market share in repairs requiring its proprietary diagnostic tool by making that tool available only to authorized dealers[s]. Farmers couldn’t fix their own tractors during critical planting and harvest windows. They had to wait for dealer appointments and pay dealer prices.
In April 2026, Deere agreed to pay $99 million to settle a separate class-action lawsuit accusing the company of monopolizing repair services[s]. The settlement requires Deere to provide greater access to repair resources, but the company admitted no wrongdoing. The FTC case continues.
Why Laws Aren’t Enough
Since New York became the first state to pass right-to-repair legislation for electronics in 2022, California, Colorado, Minnesota, Connecticut, Oregon, and Washington have followed[s]. At the federal level, the bipartisan REPAIR Act would require automakers to provide independent shops access to diagnostic codes and calibration tools[s].
But software repair locks exploit a gap in these laws. Oregon’s 2024 law was notably the first to restrict parts pairing specifically[s]. Most other laws focus on access to manuals and parts, missing the software layer that ultimately controls whether repairs succeed. Manufacturers can comply with the letter of the law while maintaining effective control over who can fix their products.
What This Means for You
For consumers, the impact is straightforward: higher costs and fewer choices. Repair restrictions burden Americans in financial distress disproportionately, according to the FTC, and communities of color and lower-income communities bear that burden more heavily[s].
Advocates argue the solution is clear: software repair locks must be addressed directly in legislation, not left as a loophole. Until then, the right to repair remains incomplete. You may own the hardware, but someone else controls the software that makes it work.

The Architecture of Software Repair Locks
Parts pairingA hardware restriction that prevents a device from functioning normally when a component is replaced with a non-original part, often enforced through software verification that detects third-party components and disables features or displays warnings. works through serialization. Modern devices contain microcontrollers, some as small as a grain of rice, embedded in components like batteries, displays, and biometric sensors. These microcontrollers store unique serial numbers and communicate with the device’s main board. During normal operation, the device performs a roll call, querying each component for its serial number. If a component reports an “incorrect” serial, features are disabled or error messages appear[s].
The scope has expanded rapidly. In 2015, only 2 iPhone parts were serialized. By 2020, that number had increased to 9, with the majority non-replaceable by anyone other than Apple without loss of functionality[s]. In one notable case, replacing an iPhone 13 display would cause FaceID to stop working, even though that model’s display isn’t attached to the FaceID illuminator. Only Apple could reset the device’s software to recognize the new part[s].
In the automotive sector, manufacturers employ VIN burningThe process of electronically pairing a replacement part to a specific Vehicle Identification Number, so the part will not function in any other vehicle without manufacturer tools.: electronically pairing parts to a specific vehicle identification number. A replacement part must be programmed for that exact VIN, preventing independent mechanics from using salvaged or aftermarket components without manufacturer tools[s].
Telematics as a Control Layer
Vehicle telematicsA wireless system in vehicles that collects and transmits diagnostic data and performance metrics to the manufacturer or service provider in real time. represent the next evolution of software repair locks. Modern cars wirelessly transmit diagnostic data, engine health metrics, and error codes directly to manufacturers. This data enables predictive maintenance and remote diagnostics, but manufacturers act as exclusive gatekeepers[s].
The competitive advantage is structural. When a vehicle detects an issue, manufacturers can contact owners before they visit any mechanic, steering repairs to authorized dealerships. Dashboard notifications direct drivers to “visit an authorized dealer” without specifying the underlying issue. GM’s vehicles automatically notify dealerships when maintenance is required “so they can contact you to schedule an appointment”[s]. Independent shops, lacking telematic access, cannot offer equivalent proactive service.
Some repairs can now be conducted entirely remotely. Tesla claims to diagnose and repair 80% of issues remotely and has used telematics to fix a tire-pressure monitoring recall affecting 700,000 vehicles[s]. If remote repair becomes standard, independent shops may be physically incapable of performing certain fixes regardless of their skill or equipment.
The Legal Framework
The Digital Millennium Copyright Act provides the legal foundation for many software repair locks. The DMCADigital Millennium Copyright Act, a 1998 U.S. law that created safe harbors for online platforms and established notice-and-takedown procedures for copyright enforcement. makes it illegal to circumvent technological protection measures embedded in copyrighted works, including the software running in smartphones, appliances, medical equipment, and agricultural machinery[s]. Manufacturers argue that bypassing parts pairing violates these provisions.
The FTC investigated manufacturers’ justifications for repair restrictions and found “scant evidence” to support them[s]. On safety, the FTC noted the logical inconsistency: manufacturers cannot argue repairs are dangerous without proper instructions while withholding those very instructions. On cybersecurity, the record contained “no empirical evidence” that independent shops are more likely to compromise customer data than authorized providers.
Deere: A Market Power Case Study
John Deere’s Service ADVISOR tool illustrates the market power that software repair locks create. The FTC’s January 2025 lawsuit alleged that Deere maintains 100% market share in repairs requiring its proprietary diagnostic tool by restricting that tool to authorized dealers[s]. An inferior version, Customer Service ADVISOR, exists but cannot perform all repairs. Deere also fails to provide generic tool developers the information needed to create fully functional alternatives.
The April 2026 settlement of a separate class-action suit required Deere to pay $99 million to farmers who overpaid for repairs between January 2018 and the settlement date[s]. The settlement includes injunctive relief aimed at improving repair resource availability, but Deere admitted no wrongdoing. The company maintains that existing agreements with the American Farm Bureau Federation already provide adequate access.
Legislative Responses and Gaps
Oregon’s 2024 law was the first to explicitly restrict parts pairing[s]. Colorado’s 2024 digital equipment law added language preventing manufacturers from installing firmwareSoftware permanently stored in hardware that controls basic device functions and cannot be easily modified by users. that reduces functionality or generates misleading alerts about third-party parts[s]. A bill that would have carved exemptions into Colorado’s law was voted down 7-4 in April 2026[s].
At the federal level, the REPAIR Act would require automakers to provide independent facilities access to diagnostic codes, calibration tools, and essential repair information. Supporters are pushing for inclusion in the Surface Transportation Reauthorization Act, which Congress must pass by September 30, 2026[s].
Physical barriers continue evolving alongside software. BMW has patented logo-shaped fasteners designed to require proprietary tools, creating another layer of friction for independent shops[s]. Each barrier, individually minor, compounds to create an ecosystem where independent repair becomes progressively more difficult.
Market Structure Implications
The repair industry represents 3% of the U.S. economy[s]. Software repair locks shift revenue from independent shops to manufacturer-controlled channels. When manufacturers bundle repair services with initial sales, they create closed ecosystems that compel consumers to choose between high-margin proprietary service or premature obsolescence[s].
The FTC found that repair restrictions disproportionately burden Americans in financial distress and communities of color[s]. As software locks become more sophisticated, the gap between what legislation permits and what technology allows will likely widen. Until laws address the software layer directly, the right to repair remains an incomplete promise.
