Companies employ various strategies to prevent unauthorized repairs and modifications to their products, protecting intellectual property, ensuring safety standards, and maintaining quality control. Hardware-based measures include physical locks, proprietary screws, and tamper-proof seals that show visible evidence of access attempts. Many manufacturers use unique connectors and custom components that aren't available on the open market, making third-party repairs technically challenging.

Software restrictions represent another significant barrier. Digital Rights Management (DRM) systems, encrypted firmware, and secure boot processes prevent unauthorized software modifications. Companies often implement authentication chips that must communicate with original components for the device to function properly. Serialization of parts allows systems to detect non-genuine components.

Legal and warranty protections form the third major approach. Void warranty if removed stickers, while legally questionable in some jurisdictions, still deter many consumers from attempting repairs. End-User License Agreements (EULAs) often prohibit modifications, and companies may use copyright law to prevent reverse engineering. Some manufacturers maintain controlled distribution networks for genuine parts and repair tools.

Manufacturers argue these protections ensure safety, security, and reliability, while right-to-repair advocates claim they create monopolies and increase electronic waste. The balance between protecting intellectual property and allowing consumer freedom continues to evolve through legislation and court decisions across various countries.
