It matches OEM part number DRY0017. When the existing battery depletes, the lock loses power and stops responding to all access methods — this battery restores full operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDRY0201 lock compatibility:\u003c\/strong\u003e\n    The DRY0201 uses a single 6V alkaline cell to power both the lock motor and the control board. Both draw from the same voltage rail, so the BMS requires a stable 6V source — lower voltage causes the motor to stall before the control board registers a valid access command.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through lock and unlock sequences on the DRY0201 platform. The BMS accepted the cell without fault codes, and the motor ran through full throw in both directions without voltage sag events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access method check:\u003c\/strong\u003e\n    After fitting the new battery, test every access method — keypad, Bluetooth, and keycard — before closing the door. The DRY0201 runs a firmware handshake after any power interruption. If that handshake doesn't complete, the lock accepts physical key only until it finishes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DRY0201 shows low battery immediately after a fresh swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DRY0201 control board reads cell voltage at startup and compares it against a fixed threshold. Alkaline cells that have sat in storage for months can measure 5.6–5.8V at rest — below the 6V threshold the firmware expects. The lock logs this as a low-battery condition before drawing any current. Use cells with a manufacturing date within 12 months and verify polarity before closing the battery compartment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth not reconnecting to the DRY0201 after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery clears the lock's active Bluetooth session. On the DRY0201, the Bluetooth module does not automatically re-advertise to paired devices after a cold-start power cycle. Open the lock's companion app, navigate to device settings, and force a reconnect or re-pair sequence. Once the app confirms the link, the lock resumes accepting Bluetooth unlock commands — confirm this before the door is closed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360224936026,"sku":"BWCS-DRL120SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360224968794,"sku":"BWCS-DRL120SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360225001562,"sku":"BWCS-DRL120SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL120SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/interstate-dry0201-replacement-battery-6v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
