Why Should You Alternate Between Two Car Keys?
2 Answers
Alternating between two keys helps prevent the situation where the other key runs out of battery. Under normal usage, a car's remote key can last for 2 to 3 years. However, if the key is left unused, its battery will typically deplete within 6 months. Removing the Mechanical Key: Gently press the small switch on the back of the key to remove the mechanical key. Opening the Key Cover: You can then use the mechanical key to open the key cover. Simply insert the mechanical key into the slot beside the key and gently pry it open. Locating the Old Battery: After removing the key compartment cover, you will see the position of the old battery. Replacing the New Battery: Replace the battery, ensuring the positive side of the new battery faces upward. Reassemble the key cover and mechanical key to complete the replacement.
I've been driving for decades and always make it a habit to rotate between two car keys. This practice has been a lifesaver. Primarily, it extends battery life because constantly using just one key drains its battery faster, potentially leaving it dead in a few months. By alternating between two keys, the battery drain is shared, allowing them to last much longer and saving you from frequent replacements. Another reason is avoiding unexpected malfunctions; frequent use wears out the key's circuit board, but rotating reduces this risk. Once, I dropped one key in water and it stopped working, but the spare at home saved the day by starting the car. I also recommend storing one key in a secure spot and rotating them weekly. After adopting this habit, both keys stay in good condition, giving me peace of mind and hassle-free driving.
