Many users ask whether the 2M2 Tank Easy Clone can clone or decode Mercedes keys using the Philips ID44 (7935) transponder. Recently, one customer contacted us regarding a Mercedes-Benz R170 SLK230 (2002 model) key that could not be cloned after updating the device firmware.
This article explains the situation and clarifies which ID44 chips are supported by the 2M2 Tank Easy Clone.
Customer Question
The customer purchased a 2M2 Tank Easy Clone and updated both the Android APP and device firmware.
When testing keys:
- A Mercedes-Benz R170 key was detected as 7935 / ID44
- The Android APP showed Chip Type 44
- The device would not allow the cloning process to continue
However, when testing a Volkswagen key, the device identified it as ID48 and displayed “Crackable”, indicating normal operation.
The customer wanted to know whether the latest firmware was causing the issue.
Engineer’s Verification
After checking with our engineers, the answer is clear:
BMW ID44 (7935) Keys
✅ Supported
The 2M2 Tank Easy Clone can work with supported BMW applications using the Philips ID44 transponder.
Mercedes-Benz R170 ID44 (7935) Keys
❌ Not Supported
Although the transponder is identified as a Philips 7935 / ID44 chip, Mercedes-Benz R170 keys use a different immobilizer system and security structure.
These keys cannot be cloned or decoded using the 2M2 Tank Easy Clone.
Specialized Mercedes key programming equipment is required for this application.
Why Does the Device Detect the Chip But Not Clone It?
This is a common misunderstanding.
The device can:
- Detect the transponder type
- Read chip information
- Identify the chip as ID44 (7935)
However, detection does not automatically mean the chip can be cloned.
The cloning capability depends on:
- Vehicle manufacturer
- Immobilizer generation
- Security algorithm
- Supported decoding protocols
Therefore, a key may be correctly identified while still being unsupported for cloning.

Conclusion
If your Mercedes-Benz R170 key is identified as Philips ID44 (7935), the 2M2 Tank Easy Clone Tool is functioning correctly when it detects the chip.
The reason cloning cannot proceed is not a firmware problem. The Mercedes R170 ID44 implementation is currently outside the supported cloning range of the device.
For Mercedes-Benz R170 key work, dedicated Mercedes key programming equipment is recommended.
Before purchasing any cloning device, always verify not only the chip type but also the specific vehicle application, as support can vary even when the transponder type appears identical.
