Subaru Key Replacement, Key Fob Programming & Smart Key Service
From DAT17 transponder keys to push-to-start proximity fobs, we cut and program Subaru keys at your location across Palm Beach County.
Subaru keys progressed from DAT17 transponder blades to remote head keys and finally push-to-start proximity smart keys. The chip and immobilizer moved with them, so the year and whether your Subaru is turn-key or push-to-start decide which key it needs.
Our mobile techs cut and program keys for the most common Subaru lines in Palm Beach County, including the Outback, Forester, and Crosstrek. We carry blanks and programming tools in the van, confirm the exact fob by VIN and by inspecting your original key, and finish most jobs curbside in one visit.
Subaru smart keys fall in the CWTWB1U811, CWTB1G077, HYQ14AHK, and HYQ14AHC families across the years, but we confirm the exact fob by VIN before ordering, since trims and years can carry different keys.
Subaru models we service

Subaru key types by generation
Subaru keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
Mid 2000s to mid 2010s: DAT17 transponder keys
Subaru used the DAT17 keyway with transponder keys and remote head keys (commonly FCC CWTWB1U811). The chip has to match the immobilizer, so a blade that fits the lock will not start the car on its own.
Early to late 2010s: remote heads and early smart keys
Subaru continued remote head keys (commonly FCC CWTB1G077) and introduced push-to-start proximity smart keys (FCC HYQ14AHK) on higher trims, so the same model could be turn-key or push-to-start by trim.
Late 2010s to present: proximity smart keys
Modern push-to-start Subarus use proximity smart keys (FCC HYQ14AHC) with an emergency blade inside. Lost smart keys are programmed to the specific vehicle.
Subaru key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.
Subaru Outback Key Replacement

Subaru Key & Fob FAQs
Can you replace a Subaru key if I lost all of them?
Yes. We program a new key or smart key to your vehicle on site. All-keys-lost jobs on push-to-start models take a little longer because the key is programmed directly to the car.
Do you program Subaru smart keys (push-to-start)?
Yes. We supply and program proximity smart keys such as the HYQ14AHK and HYQ14AHC and cut the DAT17 emergency blade inside.
My Subaru key turns but won't start. What's wrong?
The transponder in the key has to match the immobilizer. If the blade is fine but the engine won't start, the chip may have failed and the key needs reprogramming or replacement.
Is my Outback turn-key or push-to-start?
Both exist across the years. If you insert and twist a key it is turn-key; if you press a button it is a smart key. Tell us which so we bring the correct key.
How much is a replacement Subaru key?
It depends on whether it is a transponder key, a remote head key, or a smart key, plus the year. We quote an up-front price before we head out.
Can you cut a spare Subaru key from my working one?
Yes. A spare made from a working key is the cheapest insurance against a future lockout, and we cut and program it on the spot.
Do you come to my home or workplace?
Yes. We are fully mobile and service Subarus wherever they are parked across Palm Beach County.
Why is my Subaru smart key not detected?
It is often a dead coin battery rather than a failed fob. We can test it, replace the battery, or program a new smart key if needed.
What do you need to make a Subaru key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof of ownership. A photo of your current key helps us match it.
Do you service the Crosstrek as well as the Outback and Forester?
Yes. We handle the Crosstrek, Outback, Forester, and the rest of the Subaru lineup, confirming the exact fob by VIN in each case.
