It powers the wireless locking, unlocking, and alarm functions of the keyless entry system. At 23.60 x 23.60 x 9.50mm, it fits the fob housing without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTransit Connect and MK7 fob compatibility:\u003c\/strong\u003e\n    Both models use the same fob platform and battery footprint — same voltage rail, same cell dimensions, same contact orientation. One cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against the fob's internal circuit board and confirmed stable 3V output at load. The rolling code module and button contacts drew cleanly with no voltage drop at activation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap fob re-sync:\u003c\/strong\u003e\n    After fitting this cell, stand within one metre of the vehicle and press the lock button five times. Power interruption during a battery swap can break the rolling code handshake between the fob and the BCM — this sequence re-establishes it.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Transit fob stops talking to the car after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eFord's keyless entry uses a rolling code — the fob and the Body Control Module each hold a counter that increments with every button press. When the fob loses power, the BCM can fall out of sync with the fob's counter. The car sees an unrecognised code and rejects the signal entirely. This is not a faulty battery — it is a BCM handshake reset that takes about five seconds to fix. Stand close to the vehicle, press lock five times, and the counters realign.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFob range noticeably shorter than the old battery — right after a fresh swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium vanadium pentoxide cells ship in storage state, typically sitting below their rated open-circuit voltage. The fob's transmitter module draws more current at the moment of signal burst than at idle — at storage voltage, that burst can be slightly underpowered, cutting effective range. After three to five normal uses, the cell stabilises at full 3V working voltage and transmission power returns to spec. If range stays short beyond ten presses, check that the cell contacts are clean and the cell is seated flat with no tilt against the positive terminal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339814469722,"sku":"BWCS-VL2330D8-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339814502490,"sku":"BWCS-VL2330D8-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339814535258,"sku":"BWCS-VL2330D8-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VL2330D8-1.webp?v=1778366812","url":"https:\/\/batteryweb.com\/products\/ford-transit-connect-replacement-battery-3v-50mah-lithium-vanadium-pentoxide","provider":"BatteryWeb","version":"1.0","type":"link"}
