2016 Subaru Forester: Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Subaru Forester does not support on-board programming for new key fobs. This is because the key fob and the immobilizer system are linked for security purposes. To program a new key fob, a specialized scan tool is required to communicate with the vehicle's computer and register the new key. This means you will need to have a dealership or an automotive locksmith program the new fob for you.

While this may seem inconvenient, it is a security measure that helps prevent unauthorized access to your vehicle. Without this requirement, anyone could potentially program a new key for your car.

Battery replacement

Replacing the battery in your 2016 Subaru Forester key fob is a simple process you can do at home.

1. Open the case: Look for a small indentation on the side of the key fob. Use a small flathead screwdriver to gently pry the two halves of the fob apart.
2. Remove the old battery: The battery is a CR1620 coin cell. Take note of the battery's orientation before removing it.
3. Insert the new battery: Place the new CR1620 battery into the fob, ensuring it is oriented the same way as the old one.
4. Close the case: Snap the two halves of the key fob back together.

Where to buy a replacement fob

• Dealer: The most expensive option, but you are guaranteed to get an OEM fob that is compatible with your vehicle. Expect to pay around $200-$300 for the fob and programming.
• Locksmith: A more affordable option than the dealership. Automotive locksmiths have the necessary scan tools to program new key fobs and can often provide you with an OEM or high-quality aftermarket fob for a lower price than the dealer. Expect to pay around $150-$250 for the fob and programming.
• Amazon/Online: The cheapest option, but also the riskiest. You can find aftermarket fobs for as little as $20, but there is no guarantee that they will be compatible with your vehicle or that they will be of good quality. You will also still need to have the fob programmed by a locksmith or dealer.

If on-board programming isn't supported

As mentioned, the 2016 Subaru Forester requires a scan tool for key fob programming. This is because the key contains a transponder chip that communicates with the vehicle's immobilizer system. This chip is a security feature that prevents the car from starting unless the correct key is present. When a new key is programmed, the scan tool registers the new transponder chip with the immobilizer.

If you lose your only key, you will need to have your vehicle towed to a dealership or a locksmith who can cut a new key and program it to your vehicle. This can be a costly and time-consuming process, so it is always a good idea to have a spare key.
