Panasonic VL2020 Lithium Rechargeable Battery for BMW & Transit Key Fob

PRODUCT INFORMATION - *NOTE - This is the same Panasonic Type of battery that BMW use WITH THE EXCEPTION THAT THE PCB LEG MOUNTS ARE SLIGHTLY DIFFERENT AND WILL REQUIRE MINOR MODIFICATION - these are 180 degrees as per the photo - please check yours (BMW have these made as a custom part by Panasonic with slightly different leg mounts) you cannot buy these but there are many guides on the internet showing how to change these batteries - you will need to solder the batteries in, this is not difficult but please ensure you are able to do this or have access to someone who can do it for you.

This fits Most BMW 3, 5, 7 and E46 series (check it requires the battery with pins and not the CR2032). You Cannot buy the original BMW battery, as it was a custom part from Panasonic and so BMW charge £200+ for a new key fob - this is the closest battery you can buy - you will need to change the metal tabs, however it is an easy job and the instructions are readily available on the internet

Note this also fits Ford Transit Custom Van and many other cars, you will have to be able to solder the item in, it does require soldering so make sure you are able to do this or have someone do it for you
