What to Do When the Keyless Start Key Runs Out of Battery?
2 Answers
The solutions for a keyless start key running out of battery: 1. In most cases, if the keyless start fails due to a dead battery, you can use the spare mechanical key to open the door by inserting it into the door handle; 2. For cars that appear to have no keyhole, you can usually pull the handle to find a hidden keyhole; 3. If the spare mechanical key is not nearby, you can remove the key fob to find the spare key for opening the door. Keyless start means starting the vehicle without taking out or turning the key. Simply keep the key in your bag or pocket, press the button inside the car or turn the ignition switch to start the engine. One-button start is a derivative function of this feature.
Oh, I've encountered this situation many times over the years of driving. When your keyless entry remote battery dies, don't panic. Most key fobs contain a small mechanical key hidden inside - just pry open the key casing to retrieve it for unlocking the door. Once inside the car but can't start the engine? Try placing the key near the steering wheel or start button, as some vehicles have specific induction points (like under the center console) for temporary starting. If that still doesn't work, it's time to replace the battery: Key fobs typically use CR2032 batteries, available at supermarkets or convenience stores. DIY replacement is easy - just use a coin to pry open the key cover, swap the old battery with the new one (mind the polarity alignment). I always keep spare batteries in my car and check key functionality before business trips - this habit has saved me from several troubles. Key fob batteries generally last 2-3 years; don't wait until complete failure to replace them, or you might end up needing tow trucks or emergency services.
