How to unlock a tuner locked PCM for ls engines

Finally got HPTuners and our PCM was locked from a previous tune. IT won't read or write to the PCM due to this lock. We short a pin on the circuit board which allows a new tune to be written to the pcm, removing the tuners lock. it works for most ls pcm's. some look slightly different but the pin is around the same spot. Hope this helps

On gen 3 pcms, I turn off high speed and it usually works well

I had to read this title like 6 times

[@stevegrant8443]

will this work on a stock Pcm that is locked from factory?

[@JoseMendoza-jv8qz]

What if it doesn’t let me read it

[@austinhardrick2214]

If I get a gm dealer to flash my ecm and reprogram it will I be able to tune it ?
