# DESLOC B200: The Lock Parts, Battery Bay and Separate Gateway > Opening the fingerprint deadbolt and its G2 gateway before a door installation. Canonical page: https://pyrosoft.pro/blog/secure-your-home-with-the-desloc-b200-smart-fingerprint-deadbolt-af8c7b52 Published: 2026-11-04 Some links to other products on this page are affiliate links, and we may earn a commission if you buy through them. It costs you nothing extra, and it has not changed what this article says — where a competitor is the better answer, we say so. The DESLOC B200 box has more than the front of a smart lock in it. There are templates, labeled hardware, an interior assembly and a separate G2 gateway to open as well. ## Look at both halves I go through the manuals and drilling templates, then the screws and deadbolt pieces. On the front unit, I look at the keypad area and fingerprint reader. On the inside unit, I show the battery compartment and the connector for the other half. I initially call the included batteries rechargeable, then correct that when I look at them: the supplied cells are alkaline. That correction matters more than my casual suggestion about what I might replace them with; I have not tested alternate batteries here. ## The gateway is a separate little box The G2 package includes a USB-C cable and setup information. I show the gateway’s small body and its light, then discuss its role in a connected setup. I do not pair it, install the lock or demonstrate a fingerprint unlock in this recording. The listed unlock methods and capacity are product features I am discussing, not independently verified security or reliability results. ## Installation is still ahead The useful first look is how the pieces relate before anything goes into a door. I have not carried out a forced-entry test, measured battery endurance or verified a live app workflow. The original product page is below.
