Car remote lock failure or vehicle body issues. Car remote lock failure: Due to colder weather, some grease in the remote becomes sticky, causing poor contact. The car key battery is dead. The mechanical part of the electronic chip key is usually hidden inside the key body. Simply press the small opening at the back of the key body, and the mechanical key will come out. The key got wet. Open the key, dry the inside with a tissue, and if you're still concerned, blowing cold air from a hair dryer on the key is also an option. Strong magnetic field signal interference around the parked car: It might be caused by a magnetic field, leading to one-button start failure, requiring multiple attempts to occasionally start the engine. It works normally in other locations.
