What is Push Button Start?
Push button start is a convenient feature that allows you to start your Hyundai vehicle with the push of a button rather than inserting and turning a key. As long as you have the key fob inside the car, the vehicle detects its signal and allows you to ignite the engine by pressing the Start/Stop button. This keyless access system makes starting your car simpler and quicker.
When Push Button Start Stops Working
If your Hyundai’s push-button technology stops working properly, there are some common symptoms you may experience:
- The Start/Stop button doesn’t respond when pressed
- The engine doesn’t turn over when you push the button
- Warning lights come on indicating key issues
- The car does not detect the key fob signal
If any of these happen, don’t panic. There are a few possible causes and solutions to get your push button to start working again.
Main Causes of Non-Working Push Button Start
Dead Key Fob Battery
The most common reason a Hyundai push button starts to malfunction is a drained key fob battery. Just like any electronic device, the battery needs to be replaced periodically. If it wears down too low, the signal to your car gets compromised. The fix is easy – simply putting a new battery in the smart key will usually solve the problem.
Faulty Push Button Switch
Over time and use, the Start/Stop button itself can suffer electrical failure or physical damage. If the battery in your key fob is fine, then the problem may lie with the button switch needing repair or replacement. This issue would best be diagnosed and handled by your dealership service department or mechanic.
Interference From Other Devices
Sometimes push button start problems arise from the signal getting disrupted. If you keep your key fob close to other electronics like mobile phones or laptops, their frequencies may interfere with communication between the fob and vehicle. Simply moving your keys several feet away from other devices can help overcome signal interference.
Troubleshooting Tips
Before taking more complex measures, try these basic steps to troubleshoot:
- Check the key fob battery level and replace it if low
- Make sure the smart key is close to the push button when pressing
- Reference the start issues section of your owner’s manual
- Lock and unlock doors with the fob to retry signal detection
When To Seek Professional Help
If replacing the battery does not restore function, there may be an underlying electrical issue that requires a mechanic’s diagnosis. Seek professional assistance for things like:
- Faulty push button switches
- Software problems
- Advanced breakdowns of computer modules/sensors
While inconvenient, defects covered under Hyundai’s extensive warranties are typically remedied at no cost. Your dealership can also provide a complimentary loaner vehicle if needed during repairs.
Temporary Workarounds
Until you can resolve malfunctions, all Hyundai key fobs have a handy metal key embedded inside. This mechanical key fits the door locks and a slot beside the steering wheel, allowing you basic unlock capability and manual ignition as a temporary measure.
Preventing Future Issues
To help avoid push-button issues down the road:
- Check key fob batteries twice a year and replace if low
- Store key fobs away from moisture, intense heat/cold
- Carry only your vehicle keys on the fob, no other items add weight
With proactive upkeep, Hyundai’s push-button start should provide years of reliable performance. Reach out for assistance if you have any other problems getting your keyless functions restored.

Hopefully, this overview gave you a helpful understanding of what causes Hyundai’s push-button start system to stop working along with some effective troubleshooting advice.
