Unlike a disposable button cell, it recharges in place every time the key sits in the\nignition or the vehicle's induction pocket, so a healthy cell keeps the remote working for years.\nThis is the 3-pin version with 90° angled solder legs, the same terminal bracket geometry as\nthe cell originally fitted to the fob board.\u003c\/p\u003e\n\n\u003ch3\u003eFits\u003c\/h3\u003e\n\u003cp\u003eBMW 1 Series (E81, E87), 3 Series (E46, E90, E91, E92, E93), 5 Series (E39, E60, E61), 6 Series, 7 Series (E38), X3 (E83), X5 (E53), Z4 (E85, E86) and Mini Cooper S.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eBefore ordering, open your fob and confirm the existing cell is a 20 mm coin cell\nmarked VL2020 with three solder legs.
