These days, metal keys are kind of a disappearing breed. Automakers are leaning more and more to making the plastic key fob into the genuine key. They get to get rid of the unattractive key while organizing what ends up in the pockets of customers. Even if you merely use the fob as a tool to open the door or as a key, a strong battery is essential.
The key fob was created by BMW to be the only tool required to remove the battery. A CR2450 battery is the one in concern. There will be a button on the back of the key if you turn it over to look at it. The key is visible when you press it and remove the top of the fob.
You can use the key you take out to unlock the door using a dead key fob. But you’ll also use it to take off the fob’s backing. There is a shallower area in the fob opposite the hole for the key. To unlock the backing of the key fob, insert the key into the shallower portion.
The battery is visible if you take off the fob’s backing. If you need a CR2450 battery right away, you may frequently find them in supermarkets and gas stations.
You may pry out the battery using a small tab that is located on the corner of the backing. Replace the lid after inserting the new battery with the positive side facing out.

Can a BMW battery be replaced without reprogramming?
Let’s first focus on what BMW battery registration genuinely is before delving into the procedure. Battery registration, to put it simply, is the process of notifying your car that a brand-new battery has been installed. Importantly, it must be done every time you replace the battery in your BMW, model year 2002 or later.
The car adapts the amount of energy required to recharge to operate at peak levels as your battery ages and gradually loses its ability to charge. The battery needs more charging the older it is. By registering your battery, you can inform your engine control module (also referred to as DME — Digital Motor Electronics) that a new one has been installed. As a result, the vehicle will reset the old battery statistics and won’t attempt to overcharge the new battery under the assumption that the old one is still in place.
In addition to registering, you must also code your BMW computer. No matter how different or similar your new battery is from your previous one in terms of specifications, it will still be necessary each time you change it.
