If your Smarty has become unusable, it is possible to remove it from your vehicle and load its software to another one. Smartys are essentially tuning computers that can only tune one vehicle at a time. Performance tuners can be stingy, which is why they often lock your Smarty VIN to your original vehicle. However, it is possible to unvin lock your Smarty by following the steps outlined in this article.


You have recently purchased a smartyCR from a friend and you’ve noticed that the vin on the device is locked. Unfortunately, this prevents you from unlocking it without removing it from the truck. If you’d like to unlock it without having to remove it from the truck, here are some easy steps to follow:

Restoring stock software

The Smarty programmer is a programming tool that connects to your truck’s OBDII port, located underneath the left knee bolster of the steering wheel. Once hooked up, it communicates with the ECM to tune, calibrate, and read trouble codes. Its makers, MADS Electronics, claim that it leaves no trace when removed from the truck. This makes it impossible for the dealer to detect and install the software that you have loaded onto your Smarty.

If you want to revert your Smarty Touch to stock software, you can do so by returning it to the original stock software. The new software will make your Smarty Touch un-unlockable from the VIN number / ECM. If you are unsure how to do this, you can contact a Professional Tuner for assistance. In some cases, restoring stock software to unvin locks a Smarty is necessary when you want to re-program it.
