Why the Mail-in Unlock?
We make it simple
We unlock your ECU directly at our HQ in Belgium. With logistics fully optimized, most customers experience a total turnaround time of under 48 hours.
No premium upcharges based on your vehicle's badge. Every single unlock is the exact same competitive price, regardless of the make or model.
Your ECU remains completely untouched. We do not open it or modify any physical chips on the board, and every shipment is fully insured against loss or theft.
Because the procedure is handled entirely thourough mail-in, the specific unlock method remains isolated from manufacturers, keeping our solution secure and significantly harder to patch.

How It Works?
From Identification to Back on the Road
Step 1
Identification
The process begins with identification. At this stage, the need for a Mail-in Unlock is clearly indicated. No ambiguity: if an Unlock is required, the AutoTuner interface will alert you and redirect you to the Mail-in Unlock.
Step 2
Purchase the Mail-in Unlock
Buy your Mail-in Unlock service directly on our website.
Some cars have two ECUs so you'll need to purchase an unlock for both.
Step 3
Disassembly of the ECU
Once the need is confirmed, you must proceed with disassembly. We provide detailed resources to help you in this step: video tutorials, diagrams, technical tips… everything is designed to make the operation easier, even if you are not used to it.
Step 4
Pickup and shipment to AutoTuner
Shipping is simplified to the maximum. We provide a pre-filled DHL Express label and clear instructions to schedule the pickup of the package at your workshop or another address. You don’t have to manage transport: once the label is printed and the package prepared, DHL handles the rest.
Step 5
Mail-in Unlock procedure
This is when our technical team intervenes. The method used is deliberately confidential. Why this level of secrecy? Simply because this guarantees the effectiveness and longevity of our solution.
Step 6
ECU return
Once the Unlock is completed, the ECU is returned in record time. We don’t joke about timelines.
Step 7
Reassembly and finalization
Upon receipt, you just have to reinstall the ECU in the vehicle and continue your work.

This is false. We have already proven otherwise. Our teams evaluate case by case, depending on the ECU type, its architecture, and long-term strategy.
This is false. Mail-in Unlock is a service that can be assimilated to a repair. For this reason, we have implemented a simplified DHL procedure that, with the proper documentation, avoids import fees.
