Your trusty BMW E46 has brought you to your destination again, but suddenly the car key no longer works? Don't panic - there is a simple solution to recharge the key without the hassle of changing the battery. In this blog post, you will learn how to get your BMW E46 key back in shape in no time.
Background: Rechargeable batteries in the E46 key
The keys of your E46 use rechargeable batteries based on the principle of induction. This means that you do not need to buy expensive batteries to charge them - simply charging them with an everyday object is enough.
Step 1: Find the right "charger"
Unlike complicated special tools, you only need something you most likely already have at home - the charger of an electric toothbrush . This ingenious method not only saves money, but also shows that the solution is often simpler than you think.
Step 2: Position the key correctly
Place the key with the bottom side on the charger of the electric toothbrush. This is the part that usually goes into the ignition. Positioning is crucial, so make sure the key is in a good position.
Step 3: Patience is a virtue
Leave the rest to time and physics. Let the key charge overnight. Inductive charging requires some patience, but the wait will be worth it.
Step 4: Enjoy the regained functionality
Voilà! The next morning you will be pleasantly surprised when you can use your E46 key again – without the annoying and time-consuming task of changing the battery.
Conclusion: Simple, Effective, Free
Why bother with complicated solutions when the answer can be so simple? Charging your E46 key doesn't require expensive replacement batteries or time-consuming visits to the workshop. With this DIY trick, you not only save time and money, but you can also look forward to the next trip with your BMW E46 without worry.
