Remote key adaptation succeeds but central locking does not execute on a Golf 5.

VCDS shows signal reception but cannot force execution or diagnose why the comfort module does not actuate locks, and the greyed-out 'Save' button indicates unreliable adaptation commitment.

Implied Software Gaps

Software that provides explicit confirmation of adaptation commitment and offers circuit-level diagnostic guidance beyond generic module communication

App Concept

LockLink Diagnostics

A guided troubleshooting tool for automotive central locking systems that interprets module data, tests actuator circuits, and provides step-by-step diagnostics. Unlike generic VCDS, it integrates vehicle-specific logic to pinpoint why a remote command is received but not executed.

Key Features

Real-time actuator circuit testing with voltage/current readouts
Guided adaptation flow with clear success indicators and EEPROM write confirmation
Faulty door module detection and impact analysis on system execution
Integrated wiring diagrams and component locator for common platform errors

Target Users: Independent auto repair shops and DIY mechanics working on Volkswagen/Audi group vehicles with central locking issues

Revenue Model: $49.99 per diagnostic session or $199/year subscription for unlimited use
