2015 Subaru Legacy
Key Replacement - Save vs Dealer in San Diego

Q: How do I know you are not a scam locksmith?

Scam locksmiths hit Subaru owners hard because smart key jobs sound expensive and people are often stressed when they call. The pattern is always the same: a low number on the phone, a very different number once someone is standing next to your car, and a vague explanation blaming the vehicle's security system for the difference. EZ Car Keyz gives you a firm price on the phone. It does not change at the car.

Q: Will the replacement key work exactly like my original?

Yes. Every function gets tested before I leave - remote lock and unlock, proximity recognition, and engine start. That last one matters more than people realize. A key can appear programmed, the car might even crank, but if the immobilizer enrollment wasn't completed correctly the engine will start and immediately stall. That is a known failure point when the job is done halfway. I don't hand over a key until I've confirmed the engine runs and stays running.

Q: I lost both keys to my 2015 Legacy. Is that a harder job than just adding a spare?

It is a more involved job, yes. When at least one working key is present, adding a spare is faster because the system can recognize the existing fob as part of the process. All-keys-lost means the immobilizer has no reference point, so the procedure is longer and requires a full registration sequence through the diagnostic port.

Q: My 2015 Legacy starts fine but the remote lock and unlock buttons stopped working. Do I need a new fob?

Not necessarily. If the car still recognizes the fob for starting, the transponder side is intact. Dead remote buttons on a functioning fob usually point to the battery or the button contacts inside the fob housing, not the fob itself. Start with a fresh CR2032. If range is short or buttons are inconsistent after that, the issue is often a slightly deformed battery contact rather than the fob being bad.

2015 Subaru Legacy Smart Key Replacement - Fast, Affordable & Professional

I was over near Rancho Santa Fe Village when this one came in. A woman had parked near one of the small boutique shops off La Granada, ran inside for what she figured was ten minutes, came back, and the car just sat there.

Fob wouldn't unlock the doors. Start button inside was dark to the fob. The key-not-detected warning was sitting on the dash like it had been there a while.

She'd already done the obvious thing - popped the fob open in the parking lot, swapped the CR2032 with a fresh one she bought from the pharmacy two doors down. Still nothing.

When I arrived she handed me both batteries, the old one and the new one. The new one tested fine. The old one was reading low but not flat. What caught my eye was the battery tray inside the fob. There was a faint film of corrosion on one of the contact points, the kind that builds up slowly over years and looks almost clean until you check it under light. The battery was making contact, but it wasn't making good contact.

I cleaned the contacts, seated the new CR2032 correctly, and closed the fob back up. The car recognized it immediately. We tested all four buttons, the door handles, and confirmed the engine would start before I called it done.

She mentioned she'd been quoted a full replacement fob and programming at the dealer when she called them earlier. She didn't need any of that. Just the right fix, on site, in Rancho Santa Fe Village, for a fraction of what they wanted.

Subaru Legacy Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Subaru vehicles?▼

Yes. EZ Car Keyz holds a California BSIS locksmith company license, is fully insured, and carries the equipment and software subscriptions needed for Subaru smart key work specifically. This generation of Legacy requires professional diagnostic tools to register a new fob to the immobilizer - it is not a generic OBD job, and not every locksmith has invested in the right Subaru-compatible tooling.
