Before you begin, make sure you have a new or previously charged battery available to replace the dead battery.
Method 1: Using the Key Fob (if available)
1. Use Another Vehicle's Battery: Boost your BMW using jumper cables connected to a running car with a good battery. This provides temporary power to the car's electrical systems.
2. Press the Trunk Release Button: With your BMW powered up, check if the "Trunk Release" button on your car's key fob is functional. If it is, simply press the button to unlock the trunk.
Method 2: Emergency Trunk Release (BMW models vary)
1. Locate the Trunk Release: Most BMWs have an emergency trunk release mechanism accessible from the interior of the car. Typically, this is a small plastic or rubber lever or pull tab located near the rear seats or trunk area.
2. Pull the Emergency Release: Find and pull the emergency trunk release lever or pull tab. This should unlock the trunk manually, even with a dead battery.
3. Replace Battery: Once the trunk is open, replace the dead battery with the new or charged battery.
Additional notes:
- Some BMW models may have additional trunk release mechanisms, such as a separate keyhole beneath the trunk badge. Consult your vehicle's owner manual for specific instructions.
- If the above methods don't work or your vehicle has different unlocking mechanisms, you may need to contact BMW roadside assistance or a professional locksmith for help.
