It fits units cross-referenced under part numbers 100219, DL-120, DL-19, DL-31, DL0007-00001, EBDL-31, HTL-18, HTL12, and PT00212L. When the original battery depletes, the lock loses power to its control board, keypad, and motor driver — this battery restores that power.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-reference compatibility:\u003c\/strong\u003e\n    The part numbers above share the same 6V voltage rail, physical form factor (56.80 × 52.10 × 14.60mm), and connector spec. That's why one battery covers the full Intellikey DL and HTL series without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through the full lock cycle — motor engagement, keypad polling, and BMS communication. Voltage held stable at 6V across all three load events with no sag or cutoff trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting this battery, test every access method — keypad code, keycard, and Bluetooth app — before closing the door. Some Intellikey locks require a firmware handshake after power interruption that must complete before all credential types are accepted.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Intellikey locks reject access codes immediately after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eIntellikey's control board runs a re-initialisation sequence the moment it detects fresh power. During this window — typically a few seconds — the lock's credential store is loading from non-volatile memory. If you enter a code before that sequence finishes, the lock rejects it. This is a firmware timing issue, not a battery fault. Wait for the keypad to signal ready (usually a LED or tone) before testing any access method. If the lock still rejects a valid code, remove the battery, wait ten seconds, and reinsert to force a clean boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning on the lock display with a brand-new battery fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the lock reads initial voltage before the alkaline cell has settled under load. Some Intellikey units sample voltage within the first second of power-up — alkaline cells at rest can read slightly low before stabilising. Remove and reinsert the battery to trigger a fresh voltage read. If the warning clears, the battery is fine. If it persists, confirm the battery polarity matches the compartment markings and that the contacts are clean and making full contact — a partial connection reads as low voltage at exactly 6V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360200523866,"sku":"BWCS-DRL310SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360200556634,"sku":"BWCS-DRL310SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360200589402,"sku":"BWCS-DRL310SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL310SL-1.webp?v=1778610940","url":"https:\/\/batteryweb.com\/products\/intellikey-replacement-battery-6v-2300mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
