The phrase represents a specific scenario encountered in automotive diagnostics and security, pertaining to situations where all programmed transponder keys for a Toyota vehicle are no longer functioning or available, and an Autel diagnostic tool is employed to address this issue. It signifies a complete loss of key access, necessitating a specialized procedure to regain vehicle operability. This procedure typically involves bypassing the immobilizer system and programming new keys using an aftermarket diagnostic tool.
This “all keys lost” scenario poses a significant challenge for vehicle owners and automotive technicians alike. The inability to start the vehicle renders it immobile and necessitates immediate intervention. Previously, addressing this issue often required expensive dealership intervention or complicated electronic module replacements. The advent of aftermarket diagnostic tools capable of performing key programming in “all keys lost” situations has significantly reduced costs and turnaround times, offering a more convenient and efficient solution. This functionality represents a considerable advancement in automotive security and diagnostics.
