Honda Restricts Key/Mobilizer Functions
In case you are not already aware, starting back in 2018, you are no longer able to perform immobilizer functions within the legacy Honda Diagnostic System (HDS), such as adding, deleting or replacing all lost keys.
All immobilizer functions are now restricted to the Immobilizer Setup tool on the i-HDS Home Menu.
The application features an easy-to-understand user interface for registering keys and remotes. Simply launch it from the home menu and follow the prompts.
CAPTION: An immobilizer setup tool is available on the i-HDS home menu.
