If you’re stranded with a dead key fob battery and a BMW that refuses to start, don’t panic! This guide covers various methods for how to start your BMW with a key fob if the battery is dead, from simple solutions to slightly more technical ones. We’ll equip you with the knowledge you need to get back on the road quickly.
BMW Key Fob Dead: Your Options
Several factors influence how to start your BMW with a dead key fob. The year and model of your car will determine the specific steps. Let’s explore the common methods.
Using the Hidden Key Blade
Most BMW key fobs contain a hidden physical key blade. Locate the small release button on your fob and slide the blade out. This key can be used to manually unlock the driver’s side door. Once inside, you may find a designated slot or reader near the steering column or in the center console. Place the key fob in this slot, allowing the car to recognize the key’s internal transponder, and attempt to start the engine. This method works on many newer BMW models, bypassing the need for a functional fob battery.
Jumping Your BMW
Even if your key fob is dead, you can often jump-start your BMW just like any other car if the car battery itself is low. This method won’t help if your key fob is the only issue, but is crucial if both your car and key fob batteries are drained. You’ll need jumper cables and another vehicle or a portable jump starter. Remember to follow the correct jump-starting procedure for your BMW model, paying close attention to the designated positive and negative terminals.
Inductive Charging: Powering Up Your Key Fob
Some newer BMW models, particularly those with Comfort Access, offer an inductive charging pad. This designated spot, usually located in the center console or armrest, allows you to wirelessly charge your key fob. If your fob battery is simply low, placing it on this pad for a short period might provide enough power to start the car. Check your owner’s manual to see if your BMW has this feature. Remember that this method only works if your car battery still has sufficient charge.
Troubleshooting Common Issues
Sometimes, even with these methods, you may encounter difficulties starting your car. Here are some common issues and solutions:
- Key Fob Not Detected: If your BMW doesn’t recognize your key fob, even when placed in the designated slot, try replacing the key fob battery. If a new battery doesn’t solve the problem, the issue could be a faulty key fob, requiring reprogramming or replacement. Check if 2007 bmw key fob not working.
- Dead Car Battery: If your car battery is completely dead, jump-starting is your best option. Once the car is running, drive for at least 30 minutes to recharge the battery. If the battery continues to drain quickly, you might need a new one.
