Step-by-Step Guide to Troubleshoot Hyundai Elantra Door Locks

Experiencing issues with the door locks of your Hyundai Elantra can be frustrating, especially when you rely on them for security and convenience. Fortunately, troubleshooting the problem can often be straightforward. To begin, it is essential to identify whether the issue is isolated to one door or affects all doors. If only one door is malfunctioning, the problem may be related to that specific lock mechanism, while issues affecting all doors could indicate a more systemic electrical or wiring problem.

First, check the key fob to ensure that the battery is functioning properly. A weak or dead battery can prevent the key fob from sending signals to the vehicle’s locking system.
