Replacement Key Battery VL2020 Fit for BMW 1 3 5 6 7 Series E90 E92 E93 Entry Keyless Remote Smart Remote Contril Key Fob

Worked perfectly for BMW key fob 👍

For those people who install and the fob still does not work. You should try to find a procedure for your car to Re-initialize the key with the car. I had the same problem. I thought my fob is not working with the new battery. But I had to initialize it to my Mini with few steps with the ignition.

The battery is the exact same that was removed from the fob. The difference was the height of the prongs to be soldered in. This was a very simple job. What I did was wedge a small screwdriver between the battery and circuit board to split apart as I heated the existing solder points. The original came out with ease l, leaving enough behind to put in the new. With the prongs a little high, I snipped the top so they wouldn't interfere with the top (button side) of the fob. I then positioned the new batter prongs just under the soldering points where they were just inside the board only. With a little pressure, heated up each point again soldering the replacement battery prongs in place. There was a small gap between the board, so I took some small needle nose pliers squeezing the battery to the board. (Pliers were on top of soldering points). The prongs bent slightlly resulting in a flush install. If you don't do this you'll have negative pressure from the contact point and the battery likely ripping it off over time. Additionally, I reused the black sticker on the factory battery to ensure no electrical contact with the circuit board. I then sealed it with liquid electrical tape (basically black rubbery-plasticy glue) and clamped it until cured. All is well! Hope the battery lasts 8 yrs like the original.

Worked perfectly

Worked on my e90 bmw 328i. No issues since installing just make sure you solder it correctly and your remote works before adhering it back together. NOTE: make sure both prongs are soldered in right or else there will be times your remote will not work! This happened before and I thought it was the battery’s fault but it was just because of a loose prong. Hardly even noticeable but enough to lose connection with the vehicle from minor movement!! Always check 100% before permanently sealing up your remote.
