Common Reasons for Tesla Model 3 Not Locking

Tesla Model 3 Won't Lock?

Key Fob Battery Issue

One of the primary reasons for your Tesla Model 3 not locking could be a low or depleted battery in your key fob.

The key fob communicates with your car to initiate the locking mechanism. If the battery is weak, it may not transmit the signal effectively, resulting in a failure to lock the vehicle.

Door Handle Malfunction

Another possible cause of the locking issue could be a malfunctioning door handle.

The Tesla Model 3 utilizes retractable door handles that extend when the car is unlocked and retract when it’s locked. If the door handle fails to retract properly, it can prevent the car from locking.

Software Glitch

Sometimes, software glitches can cause unexpected behavior in your Tesla Model 3.

A software glitch might be interfering with the locking mechanism, preventing the car from locking as intended. It’s important to consider this possibility when troubleshooting the issue.
