What to Do When the Hyundai Elantra Cannot Detect the Smart Key?
1 Answers
The reason why the Hyundai Elantra displays "no key detected" when starting is due to the smart key battery being depleted. The solutions are as follows: 1. Promptly purchase and replace the smart key battery to resolve the issue. If the problem persists, it is recommended to have the smart key inspected. 2. Remote keys generally do not suddenly lose power; there are usually signs when the battery is running low, such as a shortened remote range where you need to be closer for it to respond. Occasionally, the remote key may fail to unlock the door, requiring multiple presses to work, which is also a symptom of a low battery.
