How to Use an Automatic Transmission Car Key?
3 Answers
After starting the car with the key, immediately release it and do not keep turning. If the car doesn't start on the first try, return the key to its original position and try starting again. Car keys should be stored separately and not hung with accessories or other items. Otherwise, when the key is inserted into the car, swinging during driving can affect the keyhole. If the key is kept at the waist, be especially careful when bending over to avoid pressing on the key, as excessive force can sometimes bend it.
Using an automatic transmission car key is quite simple, as we rely on it daily to start and unlock the car. First, approach the vehicle and press the unlock button on the key to open the door. Once inside, ensure the car is in the P (Park) position, press down on the brake pedal, insert the key into the ignition slot, and gently turn it clockwise to the ACC position to power on the electronics. Then, turn it further to the ON position to illuminate the dashboard, and finally to START for a few seconds until the engine starts, then release. Before driving, always check the parking brake to prevent rolling. To lock the car, press the lock button or simply close the door and use the key to lock it. If the key is a smart remote type, it can also remotely open the trunk or help locate the car, making it convenient and hassle-free. After parking, remember to remove the key and take it with you—develop the habit of not leaving the key inside the car.
As someone who frequently repairs cars, I recommend understanding the basic logic when using keys. The key ignition process involves circuit safety design: After inserting the key, turning it to the ACC position first powers small components like the audio system, the ON position activates the vehicle's entire electrical circuit without ignition, and START engages the starter motor. Automatic transmissions must be in the P position to start, which prevents hazards from incorrect operation. Remote functions also work by transmitting wireless signals to control door locks. If the key battery is low, it may malfunction, so replacing the battery promptly is sufficient. Overall, the operation is intuitive; the key is to keep the key clean and avoid physical damage, such as excessive twisting or exposure to water, to ensure longer and more reliable key lifespan.
