Older predator v2.13 locked

I plug it in to my truck and it comes up error Locked onto another vehicle.
How can I unlock this unit?

the only options you have are:

1 -- you contact seller and tell them you want your money back and give them the predator back...

2 -- or, original backup has to be restored to vehicle it was used on in order to unlock it...

3 -- or, you send to diablosport for the unlock/upgrade to 9rxx version of the tool, for $149....

4 -- or, you trade it in to diablosport for a $100 credit towards the purchase of a new inTune or Trinity...
