Unlock a tuner-locked Holden VT, VX, VY or VZ LS1 ECU — remove the locked key set by a previous tuner so you can read and edit the ECU again with EFI Live, HP Tuners or any other compatible tuning software.
Ship your ECU to us, we extract your current key, reset it to a factory GM key, and ship it back ready for re-tuning. We’ll also tell you which tuning program was originally used so you know what software to load the file with.
Non-invasive: we do not pull apart your ECU or solder to the board. Optional tune-file duplication available if you want a second ECU set up identically (e.g. with a different diff ratio).

A previous tuner left your LS1 ECU locked with a custom key and your tuning software can’t read it? Ship the ECU to us — we extract the lock, reset it to a factory GM key, and have it back to you ready for any EFI Live or HP Tuners session. No pulling apart, no soldering.
When an LS1 ECU is custom-tuned, the tuner can set a security key that locks the file inside the ECU. This stops anyone — including you — reading or editing that tune in the future unless they know the key. If the original tuner is gone, has stopped responding, or you’ve bought a second-hand vehicle or ECU, that locked key is a dead end.
Our service extracts the current key from your ECU and resets it back to the factory GM key. After the reset, any standard LS1 tuning software (EFI Live, HP Tuners, etc.) will be able to read, edit and write the ECU like normal — you’re back in full control of your tune.
We also tell you which tuning software was originally used on your ECU, so you know exactly which program to open the file with for any further work — no guesswork, no wasted trial-and-error.
We extract and reset the key without opening your ECU casing. No disassembly, no soldering to the board, no risk of damaging components or breaking factory seals.
Many competing services dismantle your ECU and solder leads directly onto the circuit board to extract the key — an invasive and risky procedure that can permanently damage the unit.
If you’ve bought a second-hand ECU, or want a backup unit / a second ECU set up with different parameters (e.g. different diff ratio), we can duplicate your tune file onto the new ECU as part of the same job. Get in touch before ordering and we’ll quote the additional cost.
Purchase this service, then ship your LS1 ECU to us. Include a note with your name, address and order number so we can match it to your job.
We extract the current key from your ECU, reset it to the factory GM key, and identify which tuning software was originally used.
We ship your unlocked ECU back to you along with a note confirming which tuning software the file was originally written with.
