This is the required first step before any ECU tuning, performance maps, or software upgrades can be installed on your vehicle.
BMW, MINI, and Toyota Supra vehicles manufactured before May 2020 use factory-locked DMEs that must be unlocked before tuning can begin.
For these vehicles, the DME can be unlocked on-site, without shipping or downtime.
We come to your location and perform the unlock safely and professionally.
⏱ Service time: typically completed in one visit
The DME controls engine operation and tuning access.
From the factory, BMW DMEs are encrypted, preventing:
• ECU flashing
• Performance tuning
• Aftermarket software installation
• Stage 1 / Stage 2 tuning
• Custom maps
• Performance and fuel calibrations
Without a DME unlock, software tuning is not possible.
This service applies to pre-May 2020 models, including:
BMW (B58, S55, S58, N55, and other supported engines)
MINI Cooper
Toyota Supra A90 / A91
*Compatibility depends on production date and DME version. Please contact us to confirm eligibility before purchasing.

*Software tuning is not included. This product covers the unlock service only.
Dealer software updates may re-lock the DME, either in person at the dealership or remotely.
This service includes one (1) DME unlock only.
If the DME is re-locked after the service is completed, an additional DME unlock service must be purchased.
We are not responsible for DME re-locking caused by:
• Dealer software updates
• Manufacturer remote updates
• Any third-party programming after the unlock
We strongly recommend requesting no software updates from the dealer unless coordinated with us.
