Why wont my Subaru key open the door?

If your Subaru key is not opening the door, there could be a few potential reasons. The most common issues include a dead key fob battery, a problem with the key fob itself, or an issue with the door lock mechanism. Let's explore these possibilities in more detail.


Checking the Key Fob Battery


The first thing to check is the battery in your Subaru key fob. Over time, the battery can die, preventing the key fob from communicating with the car's door locks. Try replacing the battery in your key fob. This is usually a simple process that involves popping open the fob and swapping out the old battery for a new one. If the key fob battery is dead, replacing it should resolve the issue and allow you to open the door.


Troubleshooting the Key Fob


If the key fob battery is fine, the issue may be with the key fob itself. There could be a problem with the internal components or the programming. Try the following steps:



  • Ensure the key fob buttons are not stuck or damaged.

  • Try pressing the unlock button multiple times in quick succession.

  • Move the key fob closer to the door when pressing the unlock button.

  • If the key fob is not working at all, you may need to have it reprogrammed or replaced.


If the key fob is malfunctioning, you may need to have it reprogrammed or replaced to resolve the door lock issue.


Checking the Door Lock Mechanism


In some cases, the problem may not be with the key fob, but rather with the door lock mechanism itself. There could be an issue with the wiring, the lock actuator, or the door latch. If the key fob is working properly but the door still won't unlock, you may need to have a mechanic inspect the door lock system.


If the door lock mechanism is faulty, it will likely need to be repaired or replaced to restore proper function.


In summary, the most common reasons why a Subaru key won't open the door are a dead key fob battery, a malfunctioning key fob, or an issue with the door lock mechanism. By systematically troubleshooting these potential problems, you should be able to identify and resolve the issue with your Subaru's door locks.
