Is the OEM GM ECM/PCM in your vehicle locked from a previous tuner? If so, our GM PCM Unlocking Service can help!  A locked PCM means that you can not read, write, or erase the PCM (not even the dealer can put it back to stock). The problem is often the tuner shops that do this go out of business, or worse you purchased the vehicle used and do not know who locked it. Without the password the computer is completely useless. We offer a PCM unlocking service that is compatible with most Gen-3 and Gen-4 GM ECMs, most all  P01, P59, E40, E38 E67, E78.   (T42 transmission modules are not supported).  2018+ Gen-5 ECMs that are locked by the manufacturer cannot be unlocked with this service.

Simply purchase the service here and send the computer to our address: PCM of NC  618 Oakridge Farm Hwy. Mooresville, NC 28115. Please note that turn around time can take 2-3 weeks. Unlocking a PCM is a complicated and time-consuming procedure.  Once unlocked, we do not alter the existing tune on the PCM.   The lock is removed and you may re-tune or modify as you wish.
