Question 1

Why is Subaru key replacement so expensive?

Accepted Answer

A few real reasons stack up. The remote head key on the 2014 Impreza isn't just a cut blade - it has a transponder chip that gets registered to the immobilizer, and the remote functions get written to the vehicle separately. The dealer runs this through their factory diagnostic software, and Subaru charges them a per-transaction fee for immobilizer access, which gets passed along to you.

On top of that, if you've lost all keys, the procedure is more involved than a simple add-a-key. The system needs to be cleared and rewritten from scratch, which takes longer and requires the right equipment.

A mobile locksmith with proper tools cuts that cost significantly - no shop overhead, no service department markup, no tow. You're paying for the key hardware and the programming. That's it.

Question 2

What exactly is a remote head key and how is it different from a regular key?

Accepted Answer

On your 2014 Impreza, the remote head key is a single unit where the key blade folds into the fob body. The fob side handles your remote lock and unlock functions and runs on a CR2032 battery. The blade side has a transponder chip embedded in it that communicates with the immobilizer every time you go to start the car.

That's the part people miss. Even if the CR2032 is dead - meaning the remote buttons do nothing - the transponder still needs to be registered and functional for the engine to start. The remote and the ignition authorization are two separate systems sharing one piece of hardware. A replacement key that's been cut but never programmed will get in the door but won't start the car.

Question 3

How does the dealer price compare to what you charge?

Accepted Answer

Way less. Dealers on these typically quote you the key cost, a programming fee, and sometimes a diagnostic charge on top. When you're all-keys-lost and they know it, the number gets higher. I've heard from Impreza owners who were looking at a significant bill before they even asked about a tow.

Call for exact pricing. I don't post numbers here because it depends on your situation - one key versus all-keys-lost is a different job. But the savings are real and I'll give you a straight answer on the phone before you commit to anything.

Question 4

My Impreza starts fine but the fob range has gotten really short. Is the key going bad?

Accepted Answer

Short range on the 2014 Impreza fob almost always points to the CR2032 before anything else. These batteries read as "good" on a standard tester right up until they don't have enough output for radio transmission. The transponder side draws almost nothing, so the car keeps starting while the remote range drops to a few feet.

Swap the CR2032 first. When you open the fob, check that the battery is seated flat against both contacts - these housings can get pried a little rough over time and the contact tabs bend slightly. A fresh battery sitting slightly off-angle will act like a weak battery.

If range is still bad after a confirmed good battery properly seated, then it's worth looking at the fob itself.

Question 5

I bought a replacement fob online. Can I program it myself or do I need someone to do it?

Accepted Answer

You'll need someone with the right equipment. The 2014 Impreza does have an onboard programming sequence, but it only works as an add-a-key when you already have a currently programmed working key to trigger the process. If you're adding a second key to a car that already has one functional key, that procedure can work. If your original is dead or missing, there's no DIY path - it requires a diagnostic tool connected to the OBD port to write the new key to the immobilizer.

Also worth knowing: the fob you bought online needs to match the factory ID for your vehicle. A lot of aftermarket fobs look identical and the buttons work fine after programming, but confirm it's the right replacement before assuming it's good to go.
