What to Do When the Hyundai One-Button Start Doesn't Respond?
2 Answers
The solutions for a Hyundai one-button start not responding are: 1. Turn the steering wheel left and right while pressing the engine one-button start to release tension and unlock the steering wheel lock; 2. Shift the gear into P position; 3. Directly use the mechanical key to insert into the keyhole for starting. Hyundai models include: Elantra, Mistra, Tucson, Sonata, Beijing Hyundai ix25, etc. Taking the 2019 Mistra as an example, it is a mid-size car with body dimensions of: length 4710mm, width 1820mm, height 1470mm, wheelbase 2770mm, minimum ground clearance 152mm, fuel tank capacity 62L, and body weight 1481kg.
I recently encountered an issue with the push-button start not responding, which was quite annoying, but it can be resolved by checking step by step. If the key fob battery is dead, the car won't detect the signal—try pressing the key fob button to see if the red light flashes. If it doesn’t, replace the battery immediately, usually with a CR2032 model. It could also be that the car battery is low, especially if it’s been parked for a long time. Before starting, check if the headlights are bright—if they’re dim, you might need a jump-start or to recharge the battery. Also, don’t forget to press the brake pedal firmly, as the push-button start requires this step to recognize the action. If the key is in your pocket or bag and the signal is weak, take it out and place it near the center console. If none of these methods work, you’ll need to visit a repair shop to check the start module or wiring issues—don’t delay to avoid being stranded on the road. For routine maintenance, remember to replace the key fob battery once a year and test the car battery every two years to minimize such issues.
