Restore reliable locking, unlocking, and starting functionality with this Replacement Rechargeable Lithium Keyfob Battery (VL2020 with 90 Degree Pins), designed for BMW key fobs that do not use a removable coin-style battery.
BMW rechargeable key fobs charge internally while the key is inserted into the ignition or slot. Over time, the factory VL2020 battery degrades and loses its ability to hold a charge, leading to intermittent locking/unlocking, reduced range, or complete key failure. Once depleted, the battery will no longer recharge and must be replaced.
This VL2020 rechargeable lithium battery is a direct OEM-style replacement and is designed to be spot-welded or soldered into the original keyfob circuit board. Once installed correctly, it restores proper charging capability, key range, and long-term reliability.
Ideal for preventative maintenance or repairing a non-responsive BMW key, this battery offers long service life and factory-correct performance when installed properly.
