Question 1

How do I spot a fake locksmith before I get ripped off?

Accepted Answer

Three things to check before you hand anyone your keys.

First, look up the business name on Google and Yelp and read recent reviews, not the star rating, the actual text. Scam operations cycle through dozens of different business names that all route to the same call center. If the reviews are all five stars with no detail and posted within the same two-week window, that's a signal.

Second, ask for a firm phone quote specific to your vehicle. A real locksmith will ask your year, model, whether it's push-to-start or a turn-key ignition, and how many working keys you still have. That information changes the job. If someone just says "we do all cars for $29" without asking a single question, hang up.

Third, in California every locksmith business is required to carry a BSIS license. Ask for the number before they start any work. A legitimate operation gives it to you immediately.

Question 2

What exactly is a smart key and why does my 2024 Forester need it programmed?

Accepted Answer

A smart key is more than a remote. The fob your 2024 Forester uses communicates wirelessly with the vehicle's security system to verify it's an authorized key before the engine will start. It also handles proximity detection, so the car recognizes you're nearby and allows door handle touch unlock without pressing a button.

The 4-button fob handles lock, unlock, and the other functions built into those remaining buttons.

Here's the part that catches people off guard: you can buy a fob online that matches the factory FCC ID exactly, and it still won't work until it's been registered to your specific vehicle using professional diagnostic equipment. The cut and the programming are two separate steps, and you need both done correctly. Some locksmiths can clone a key from an existing working fob but can't originate one from the VIN when all keys are lost. That distinction matters a lot if you're in an all-keys-lost situation.

Question 3

What equipment do you actually use to program a 2024 Subaru smart key?

Accepted Answer

For the 2024 Forester I use a professional immobilizer programmer with current Subaru software, updated to support the revised security protocol that came in on the newer model years. The smart key registration process runs through the diagnostic port and communicates directly with the body control module and the smart key control unit.

For all-keys-lost situations, the job involves a timed reset sequence built into the system, so it takes longer than a simple add-a-key. I also cut the emergency insert blade that lives inside the fob, because if the battery dies completely you'll want a way into the car.

If a locksmith can't tell you specifically what tool they're using on your Subaru and whether their software covers the current generation, that's worth asking about before they start.

Question 4

My Forester starts fine but the door handles stopped detecting me. Is that the fob or something else?

Accepted Answer

If the start button still sees the fob and the car runs normally, the fob itself is probably not the issue. Proximity touch unlock and the start function use different signal paths, so they can fail independently.

Start with the CR2032. A battery that's low but not dead will often drop proximity range before it affects the start function, sometimes by several feet. Swap it, make sure it seats flat against both contacts, and retest both door handles.

If one handle works and one doesn't after a fresh battery, the problem is almost certainly on the door side, either the handle sensor or the wiring to that door, not the key. If neither handle works but the start button is still happy, that points toward the smart key antenna or the body control module rather than the fob itself. Either way, replacing the fob won't fix it.

Question 5

I have one working key for my 2024 Forester. Should I get a spare made now or wait until I need it?

Accepted Answer

Make the spare now. One working key is the worst position to be in on a 2024 Subaru smart key system, because if that fob fails or gets lost, you're in an all-keys-lost situation, which takes more time and costs more than a straightforward add-a-key while a working fob is still present.

Adding a second key while the original is in hand is a faster job. The system can verify the existing key, which simplifies the registration process.

I keep fobs on hand for this vehicle and can come to you in La Colonia or anywhere in Oxnard. Don't wait for a crisis.
