4 Causes of Subaru Remote Start Not Working

Having trouble with your Subaru remote start not working? You’re not alone, as many Subaru owners occasionally face this issue. There could be various reasons behind the problem, ranging from StarLink activation delays to issues with the infotainment system.

In this article, we’ll explore some common causes for a non-functioning Subaru remote start and provide helpful tips to get your system back in working order. So stay tuned and discover the solutions right at your fingertips.

Common Causes of Subaru Remote Start Not Working

Dead or Weak Fob Battery

One possible reason your Subaru remote start isn’t working is a dead or weak fob battery. When the battery in your remote fob becomes weak or dies, it can no longer send the signal necessary for the remote start system to function. To remedy this issue, you can try replacing the battery in your fob. This is usually a simple process that requires a small screwdriver to open the fob’s casing and insert a new battery.

Unpaired Remote Fob

If your remote start isn’t working, it could be due to an unpaired remote fob. This can happen if the fob has lost its connection to your vehicle or if you have recently replaced the fob’s battery.

Faulty Keyless Entry System

A faulty keyless entry system could be another cause for your Subaru remote start not working. If the remote start feature does not work, even with a new fob battery and a properly paired fob, there may be an issue with the keyless entry system itself. In this case, it’s important to have a professional diagnose the issue to determine the best course of action.

Remember, a non-functioning remote start system can be frustrating, but addressing common issues like a dead fob battery, an unpaired fob, or a faulty keyless entry system can help you get back on the road quickly.

How to Fix Subaru Remote Start Not Working

When your Subaru remote start is not working, there are several actions you can take to troubleshoot and resolve the issue. In this section, we will cover three potential solutions: Replacing the fob battery, resetting the remote start system, and reprogramming the remote fob.

Replacing Fob Battery

A common reason for the remote start not working is a depleted battery in the key fob. To replace the battery in your fob, follow these steps:

  1. Carefully pry open the fob using a small screwdriver or another thin tool.
  2. Locate the battery and note its size and type (usually a CR2032 coin cell).
  3. Remove the old battery and replace it with a new one, ensuring that it is seated correctly.
  4. Close the fob and test the remote start function.

Reprogramming the Remote Fob

If the previous solutions did not resolve the issue, you might need to reprogram your remote fob. Below is a general process for reprogramming:

  1. With the vehicle off, insert your key into the ignition.
  2. Turn the ignition switch to the “ON” position without starting the engine.
  3. Press and release the remote engine start transmitter’s “Start” button three times. The vehicle’s horn should honk each time the button is pressed.
  4. Turn the ignition back to the “OFF” position and remove the key.
  5. Test your remote start function to ensure the reprogramming was successful.

Please keep in mind that these are general guidelines, and the specific procedures for your Subaru model may vary. Consult your owner’s manual or contact your local Subaru dealer for more information.

Radio and Security Related Issues

Immobilizer Errors

One common issue associated with Subaru remote start not working is immobilizer errors. Your vehicle’s immobilizer is a security feature that prevents the engine from starting without the correct key or key fob. If there is a problem with the immobilizer system, it might cause the remote start function to fail.

To troubleshoot immobilizer issues, try the following:

  • Ensure the key fob battery is not dead or low on power
  • Check for any damage to the key fob, as this may affect its ability to communicate with the immobilizer system
  • If you have a spare key, try using that to start the vehicle as it may help rule out an issue with a specific key fob

If the issue persists, you may need to visit a Subaru dealership or a qualified technician to properly diagnose the issue.

Starlink Issues

Another possible reason for remote start issues in Subaru vehicles is related to the Starlink system. Starlink provides various connectivity features for your vehicle, including remote start functionality. However, if there is a problem with the Starlink system, your remote start feature may not work properly.

Here are some steps you can take in case of Starlink issues:

  1. Reset the infotainment system – hold down the power button for at least 10 seconds. This process may resolve minor issues within the system.
  2. Verify that your vehicle has an active Starlink subscription, as remote start services require a valid subscription.
  3. Wait for at least a week after your purchase or if you have recently renewed your subscription, as it can take time for some Starlink services to become fully activated.

If none of these troubleshooting steps work, contacting Subaru customer support or visiting a Subaru dealership may be necessary to resolve the issue with the Starlink system.
