DIY Guide: How To Program a Subaru Key FOB Without a Scan Tool

Setting up a new Subaru key can make a world of difference when locking your vehicle.

However, if you don’t have a scan tool to program it on your own, don’t worry. We’ve got the perfect solution.

Here, we’ll walk you through the steps you need to follow to set up your new key without using a scan tool.

What You Will Need

We’re going to keep it simple by only using a few tools for this job.

  • A new key FOB—you can get a new key for the vehicle on either Amazon or eBay.
  • A razor—you need to open up the keyless remote as there is a code inside that you need to write down.
  • A flathead screwdriver—if you can’t open the key FOB, you might need a screwdriver to get inside.

Have it Cut

If you already got a key for your vehicle, you might have to cut the key for it to fit inside the ignition.

It needs to match the original. Otherwise, it won’t work.

We suggest hitting up a locksmith. Locksmiths know their stuff, so it’s best to get in touch with them for this kind of job.

Open It Up

First and foremost, you need to open up the key FOB. For this, you want to grab your razor and run it along the line of your key.

By doing this, you’ll gain access to the inside of the key. If you can’t get it off with a razor, you might want to use a flathead screwdriver to get in-between.

Once you’ve taken it off, you should see a string of numbers. You want to write down the first set of numbers.

Set Up The Key FOB

After opening the key, you want to sit on the driver’s seat. So, open the door and then close it.

Now grab your key and put it inside the ignition. Here, you want to turn it to the on position ten times.

When you’ve turned the key ten times, you should hear a chime sound coming from the cluster.

When you hear that sound, go ahead and open and close the door. Yet again, you should be able to hear the chime sound.

And so, the countdown begins. Here, you only have 45 seconds to enter the numbers you previously wrote down.

To insert the numbers into the computer, you have to use the lock and unlock buttons on the driver’s side.

Say, for instance, the first number of your string is four; you must press the lock button four times for the number to be recognized by the vehicle.

To move to the next number, you have to press the unlock button.

From there, please open the door and then close it. Next, take off the key, and then proceed to open the door and then close it.

After nearly five seconds, your new programmed key should be working.

And that’s all there is to it. If you’d like to watch a video on this topic, we suggest checking this video out:

DIY Guide: How To Program A Subaru Key FOB With a Scan Tool

With a scan tool, you don’t have to manually use the door lock switch to enter the serial number. That said, here are the steps for this simple job:

What You Will Need

Here is what you need to set up a Subaru key FOB:

  • A laptop—for the scan tool to work, you need a working laptop. It does not matter what type of laptop you have. As long as you can run Windows, you’re good to go.
  • A scan tool—you’re going to need a scan tool to connect your laptop to your vehicle.
  • A butter knife or a flathead screwdriver—to open up the key, you need anything small enough to get in-between the key.

Download Subaru SSM III

The only software you need to program your key is the Subaru Select Monitor software.

That’ll allow you to set up the key without pressing the lock and unlock buttons.

Once you’ve downloaded the software, you need to install it and then create a shortcut on your desktop.

Set Up The Scan Tool

After you’ve downloaded the program, you want to configure the scan tool.

For this, you want to hop in the vehicle and then go underneath your car’s steering wheel.

Here, you should see a port. That is where you want to plug it in.

The other side of the USB cable must be connected to your laptop. After that, your PC should pick it up.

Open It Up

Subaru key FOB programming instructions: there is a serial number inside the keyless remote.

That set of numbers will tell the computer that there is a specific key you want to use for your vehicle.

If you turn the key around, you should see a slot across the keyless remote.

Every key is different, so you want to check around until you see that little slot.

Once you’ve found the slot, you want to grab a butter knife and put it inside the slot.

When you’re inside, twist the knife around until you can crack it open.

Program The Key

Here, you want to turn the ignition on. From there, you want to open up the software.

After that, find the option called “integ unit mode.” When you click on it, a window might pop up saying that an error has occurred.

When that happens, you want to click on “ok.”

You should now see a different window with a bunch of options. The only option you care about is the Keyless ID registration.

When you’ve clicked that option, another window should pop up with an input field.

There, you need to enter the serial number of your key. After that, click “ok.”

After entering the ID for your key, you should see a window with the following text: “ID registration completed.”

When you see that text, click on “Cancel,” and then go back to the main menu.

You must now turn the ignition off and then get the key out of the ignition. Your keyless remote should work now.
