It delivers the steady voltage rail this lock's motor driver and microcontroller require. Fits the lock's internal battery compartment at 103.05 x 58.10 x 15.76mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKIE101-6AP-1 platform fit:\u003c\/strong\u003e\n    The KIE101-6AP-1 uses a single 9V cell to power both the motor drive circuit and the access control logic board from one supply rail. A cell that sags under load causes the motor to stall and the keypad to report errors simultaneously — this battery holds voltage through the motor draw spike.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through repeated lock and unlock sequences on the bench. The BMS in the lock registered a full-charge state and the motor drew cleanly without triggering the low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access method check:\u003c\/strong\u003e\n    After fitting this battery, test the keypad, Bluetooth app, and any keycard before closing the door. Some firmware versions on the KIE101-6AP-1 run a handshake sequence after power interruption — all access methods must confirm ready before the door is shut.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the KIE101-6AP-1 keypad freezes mid-entry after a battery change\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe KIE101-6AP-1 runs its keypad controller and motor driver off the same 9V cell. If the replacement battery has been sitting in storage and its open-circuit voltage has dropped below roughly 8.4V, the lock's microcontroller boots but the motor draw pulls the supply low enough to reset the logic mid-cycle. The keypad lights up and then freezes or clears the entered code. Use a fresh cell — storage-depleted alkaline batteries at 8.0–8.3V are too marginal for this lock's combined current draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning shows immediately after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the lock beeps or flashes a low-battery warning seconds after you install a fresh cell, check polarity first — reversed installation reads as no voltage on the lock's sense pin and triggers the warning instantly. If polarity is correct, the lock's detection threshold may be tripped by a brief voltage sag during initial motor engagement; remove the battery, wait 10 seconds, and reinsert it so the microcontroller reinitialises its voltage reference from a stable standby state. Confirm the cell reads at least 9.0V on a multimeter before reinserting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360220938330,"sku":"BWCS-DRL250SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360220971098,"sku":"BWCS-DRL250SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360221003866,"sku":"BWCS-DRL250SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL250SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/kiesub-kie101-6ap-1-replacement-battery-9v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
