What to Do When a Keyless Start Car Key Runs Out of Battery?
2 Answers
Keyless start models usually have a smart key slot, which may be located inside the center console or beneath the cup holder mat in some models. When the smart key runs out of battery, insert it into this slot. After a short wait, the vehicle will detect the key's presence and allow the engine to start. More related information is as follows: Car Key: A car key is a tool used to operate a vehicle. Modern car keys utilize a chip-based magnetic system. The ignition lock's reading coil scans the key's chip, which contains fixed digital information.
Last time my car key suddenly ran out of battery, it was really nerve-wracking! Fortunately, I discovered that all keyless entry cars have a hidden mechanical keyhole, usually concealed under the door handle cover—just pry it open with your fingernail to reveal it. Once inside the car, don't panic. Press the key firmly against the push-to-start button (the induction spot varies by model—some are on the steering wheel side, others under the cup holder). The system can then detect the weak signal, allowing you to start the engine by holding the ignition button while pressing the brake. Always keep a spare CR2032 coin cell battery in your glove compartment—it costs just five yuan at convenience stores. Replacing it yourself by removing the key's back cover is super easy and saves over 200 yuan compared to dealership service.
