For high-quality technical recovery, you have three primary paths: the official hardware service route, a complex chip-level hardware bypass, or a specific software configuration workaround if you still have Windows access. 1. Hardware Bypass (Chip-Level)
While often effective on traditional laptops, removing the CMOS battery on a Surface Pro 4 is unless you have advanced repair skills. The components are deeply embedded and soldered.
For individual consumers, Microsoft Support cannot generate a password bypass code over the phone. However, if the device is under warranty or an active business support contract, they may authorize a hardware replacement (RMA) if you can present an original proof of purchase.

Microsoft does not program backdoor master passwords into the Surface Pro 4 firmware.
Given the Surface Pro 4's discontinued status, official support is limited, but it's worth exploring.
The official, unequivocal position from Microsoft is clear: "You cannot reset your UEFI password, and Microsoft cannot retrieve it". There is no standard "backdoor" or universal master password for Surface devices. However, this doesn't mean all hope is lost. While brute-force attempts are futile, specialized, advanced techniques offer a glimmer of hope. CH341A USB Programmer or RT809F programmer
This appears immediately after turning the device on, often with a black screen and a padlock icon. This password prevents changes to hardware settings like boot order. 2. The Enterprise "Backdoor" (If Applicable)
: Upon restart, a red box will appear. Enter characters from your certificate thumbprint (as prompted). Even if it rejects the unknown UEFI password, it may allow the new SEMM settings to apply.
For a guaranteed, high-quality reset, you must reprogram the BIOS chip directly. This requires moderate soldering skill or a willingness to take the device to a repair shop.
This is the most advanced and riskiest method. It involves directly reading and rewriting the BIOS chip using external hardware.
This process is extremely risky; it can break the screen during disassembly or corrupt the touch screen firmware, rendering touch input unusable. 2. Software Workaround (SEMM Method)
