You must perform the following in order to enter your BMW’s trunk while the battery is dead:

Do I need to reprogramme my car after a battery change?

I’m here. Battery programming has nothing to do with changing the battery. When jumped, a car that had completely lost electricity from its battery due to the dome light being on will function normally. The key fob can require programming when the battery is changed. As the vehicle computer is reset, the key fob’s programming to the computer will be lost. The computer won’t lose its memory, though, if a 9-volt battery saver is inserted into a cigarette lighter and the car battery is removed. Seek out a specialist, like one from Your Mechanic, if you require more help with your battery.

In less than two minutes, find out if your auto insurance is being overcharged.

Great inquiry. You can use an OBD-II scanner or unplug and replug the positive battery terminal to reset the ECU.

The bolt on the battery terminal needs to be loosened using a tiny wrench for the first technique. Just unplug the wire and allow the vehicle to sit for at least five minutes. After that, secure the cable again and tighten the clamp. Check to verify if the dashboard lights are still present after starting your car.

An OBD-II scanner is required for the second technique. Connect it to the OBD-II port on your car, which is normally under the steering wheel. Error messages will be presented. The option to remove the errors from the system will then be presented to you. Start your automobile after that to see if the error lights are still on.

It should be noted that if you continue to experience error symptoms after changing your battery, it may indicate that your ECU is having problems or that there is another problem entirely. Because the majority of ECUs are self-learning, they should reset once they recognize that a fresh battery has been placed.

If you’re having trouble, ask a mechanic for help. You should expect to pay $50 to $150.
