Keep your "tuned" vehicles safe from dealer updates!
 
This is a Universal OBD II port lock for all vehicles with OBD II ports.  The Tune Saver is designed to keep unauthorized persons from accessing your vehicle's computer through the OBD II port: prevent the dealer from uploading software updates to the control logic or changing performance parameters; prevent maintenance, performance or vehicle history data from being downloaded; and prevent vehicle specific data (such as electronic key codes) from being downloaded. The Universal Tune Saver is a tool of total prevention of access to the OBD II port, or a tool of informed consent to get the dealer to divulge completely his intentions for your vehicle's computer.
 
Each Tune Saver purchase comes with one Secure Key.  Extra Secure Keys can be purchased from the Keys page.
 
The locking mechanism is located in the front of the lock when installed on the OBD II port.
 
Manufactured entirely in the USA of billet aluminum and stainless steel.  This lock is intended only for OBD II ports.
