Subaru Keyless Entry Not Working – What To Do?

Like all other modern car manufacturers, Subaru has adopted remote keyless entry (RKE) systems for their vehicles.  However, when the RKE system does not work from the key fob, what should a Subaru owner do?  If you're a Subaru owner, worry no more because we've done the research for your reading pleasure.

Even if the Subaru key fob's remote functions stop working, you can still lock and unlock your vehicle using four different methods.

  1. Use your spare key fob.
  2. Use the emergency mechanical key on the malfunctioning key fob.
  3. If equipped and configured, use the vehicle's PIN access.
  4. If subscribed and configured, use the Subaru Starlink app.

However, aside from using the spare key fob, all other methods will not allow you to drive your Subaru.  You will still need a mechanical key or a key fob to start the engine.

Most Subaru dealers should provide two sets of keys or key fobs to their new car buyers.  If your main key fob malfunctions at home, then you can try using your spare key fob to unlock the door remotely.

In case you do not have a spare key fob, it may be a good idea to purchase one now.  You may visit your Subaru dealership to have a new one programmed, or you may purchase and program one yourself.

As we mentioned earlier, your key fob is only one part of your entire RKE system.  To isolate your problem's source, you will need to test which part of your system is failing:

  1. Your transmitter (e.g. your key fob or your app)
  2. The receiver (your car's RKE module)
  3. The physical car component you are controlling

You may need to do some reprogramming work if you change your key fob's battery or if you bought an aftermarket key fob.  Different manufacturers have different key fob programming steps.
