2PCS VL2020 For Panasonic Rechargeable VL2020 Battery BMW For BMW X3 X5 X7 Z4 E60 E81 E91 E92 X5 Z4 E39 E46 E52 E90 E96 For Ford Transit BMW Mini Key VL2020 Replacement Battery

I needed to replace the battery in two old car keyfobs as they had stopped charging. Both work perfectly after fitting the new batteries

First class service

Got what I ordered part came next day and works for my car fob will buy again if needed

I fitted into two BMW key fobs, needs simple soldering, but all works very well.

Perfect replacement for my Keys

I tested this battery for the BMW Remote Control Key Fob F1Here's what I found...Pros ✅ the sizing was spot on - 2cm diameter and 2mm thick (A 2020 battery should be 2cm diameter and 2mm thick; the sizing is logical = 2020 !) and with the contacts in the correct place.Mine had the correct voltage - this is important as it won't activate the fob if the charge is low (I hear that if it is <2.5 volts it may not work). If that happens - you see the key sign on the dashboard - see my photo.This is a reminder that batteries run down - so use the spare fob regularly to keep it charged up otherwise you can have an unpleasant surprise when you need it !The battery comes in a robust protective case - important as the pins are fragileReplacing the "Comfort Access" Key fob Battery is tricky compared with the basic disposable battery version - so do check out the videos posted on the www as I found several good ones and make sure that you have the de-solder tape to unstick the old bettery from the PCB.. Also - note, there are some fobs that need the battery pins at 180 degree separation and others that need the 90 degree one. This battery is the 90-degree type.Cons ❌ None for me - as long as it proves durable.Delivery was next day, which is good service if you need this in a hurry as it is not easy to get on the high street. It is a lot cheaper than asking the Main Dealer garage to do this for you - but you do need so electronic circuit skills !If they fail inside 2 years I will be back to update my review.

Properly made replacement batteries with the correct spacing and thickness of the legs for BMW E series diamond keys.The batteries came already charged with 3volts charge and are marked up as Panasonic. Nicely protected in plastic cases.Note that you have to cut open the original keys and solder in the replacement battery before glueing the key back together.If the keys are not used in the car for a long time, and therefore not getting charged by the car, I find a toothbrush charger perfect to charge them up, just place the keys through or against the charger, perfect for the spare key.
