  • By depressing the release button on the rear of the fob, you can remove the secret key from your key fob.
  • Find the slot where your manual key goes. On select BMW models, the trunk or the lid may have a manual key slot. In that case, open the trunk.
  • Find the door’s keyhole. Try the door if you can’t find anywhere to use a key on the trunk. Particularly the driver’s side door is likely to feature a place for a manual key. If so, open the car door.
  • eject the concealed key container. If there doesn’t seem to be a key slot on your door, it might be hidden in a hidden compartment under the door handle. The key slot can be seen if you wedge the key into the opening beneath the compartment and pop it off. Lock the vehicle.
  • For trunk access, fold down the back seats. Your jumper cables will be available to you at this time.

How can you use a dead key fob to start a BMW?

You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.

Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.

Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.

A BMW 520i’s battery can be found where?

One of the key components of a car’s electrical system is the battery. It essentially stores electric electricity that is used to power the car’s electric components. It is important to have the battery in top working condition as a result. The truth is that a car battery is not a durable component; it will eventually and irreversibly get drained. To be more specific, the creation of electricity from chemical reactions inside the battery will become inefficient. Battery life is only 3 to 5 years, therefore charging will be useless beyond that time. A new battery should be installed if this occurs. There is a possibility that the battery will lose power as a result of dirty connection points. Poor connections can eventually occur from corrosion of a battery’s terminals. When this occurs, the battery will no longer benefit from alternator charging. It will eventually run out of power and stop producing electricity. By removing dirt from the cable and battery connections, the battery may regain some of its original efficiency and become usable again. If the engine hasn’t been started in a few weeks or so, the battery may also lose power. Recharging the battery will probably restore its efficiency when this occurs. You’ll need a battery charger before you can start the recharge.

Important! It’s possible that some BMW 5 Series (F10, F11, F07) automobiles have an IBS (Intelligent Battery Sensor) technology installed. That indicates that your Service center has to register the newly replacement battery. Avoiding battery registration could result in a failure of the power management system and inaccurate readings on the on-board computer’s display.

*Note: If more than one battery type is appropriate for your model, compare the specifications of the battery that is already installed in your car to those in the table below before selecting the best one.

Typically, the following equipment is sufficient for replacing batteries:

  • 10 and 13 mm sockets or wrenches
  • screwdrivers with flat-head and Phillips heads

3. The battery for the BMW 5 Series is hidden behind the floor carpet in the trunk.

Disconnect the negative connection on the old battery before removing it to begin replacing it. By doing this, unintentional short circuits between the positive battery terminal and the car’s body will be avoided. Make sure the cable does not make touch with the battery terminals when changing the battery. The minus (-) sign next to the negative battery connector serves as a visual cue (1):

1. Remove the positive terminal cover:

Positive connection disconnected:

Disconnect the battery’s venting pipe if it’s there. Some vehicles use battery ventilation systems to exhaust hydrogen-containing generated gases outside.

Remove the old battery from the battery compartment (notice that the battery is heavy and improper lifting could cause back injuries):

Before installing the new battery in the car’s battery compartment, do not remove the plastic terminal caps.

To guarantee optimal contact, if necessary, clean battery wires of any corrosion or debris before joining.

Instead of unplugging the battery, connect the cables, beginning with the positive terminal.

How long does a battery from a BMW 5 series last?

The typical battery life of a BMW 5 Series is 3 to 5 years, but this can greatly vary based on driving patterns, weather conditions, battery size, and type.

What occurs when the battery in a BMW is low?

After you turn off your BMW, your battery continues to run for a while. After you leave, it will continue to run your radio, lights, clock, and even the security alarm for the car. Electrical issues with your BMW could cause some components to turn off while others, like your lights, remain on, draining your battery. When you leave your BMW, make sure all electric components are turned off.

Can you use the trunk to charge a BMW battery?

My installation is in the trunk. It’s usually preferable to have the charger as close to the battery as feasible when it comes to charging. The negative lead should be linked to the chassis, not the battery, and the positive lead should be attached to the battery terminal.

The trunk has BMW batteries—why?

Instead of the more conventional engine-bay-mounted battery, the majority of BMW vehicles use a trunk-mounted battery. Because of the constrained engine bay space (a powerful engine must fit into a tiny space) and the need to maintain a weight distribution that is as close to 50/50 as possible.
