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.

He advises checking the battery as your first action. If you have to press the lock or unlock button on the remote numerous times before it locks or unlocks, it could be a sign that the battery is starting to lose power, according to Freeman.

“It (the key fob) does send a signal continuously, so it drains the battery in the key fob and its causing an excessive drainage on the battery of the automobile,” noted Freeman. “A computer is identifying that signal saying I’m ready to start.”

According to Freeman, if the key fob malfunctions, the automobile frequently won’t start because the computer system won’t acknowledge that the key fob is present in the vehicle.

“In most situations, the owners’ manual will clear that up for you, or practically any auto repair facility can replace that battery,” Freeman continued.
