For 2000‑2013 Subaru Legacy models in the U.S. and Canada, replacement keys typically involve cutting a metal key blade and, on immobilizer‑equipped vehicles, programming a transponder chip to the vehicle’s anti‑theft system using appropriate diagnostic equipment or dealer tools. Separate wireless keyless‑entry remotes must also be programmed to the car, usually via an on‑board or OBD‑based procedure or by a professional service, depending on year and system design. Programming requirements and capabilities vary by model year and keyless‑entry system, so many later vehicles or lost‑all‑keys situations may require dealer or professional locksmith programming support.
Key types used on the Legacy:
standard mechanical key with separate keyless entry remote (no transponder) (2000-2004 (select trims; some early 2000s Subaru models used non‑immobilizer keys; specific Legacy immobilizer adoption is not clearly documented in the consulted sources))
transponder chip key with separate keyless entry remote (approximately mid‑2000s and later, as Subaru expanded immobilizer use across the lineup; exact start year for Legacy not clearly specified in available sources)
remote keyless entry fob (separate from key) (2000-2013 (multiple designs and part numbers; fob style changed over time but remained a separate remote, not an integrated flip or smart key, according to aftermarket Legacy remote listings))
no factory smart/proximity push‑to‑start fob documented for these years (2000-2013 (consulted Subaru key‑fob and remote catalogs for Legacy in this period only show conventional remotes, not smart/proximity fobs))

This year needs a programmer/scan tool - there is no owner-followable onboard sequence. A mobile locksmith confirms your key type and FCC ID, then programs it on site.
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.

Common questions
Does my 2000–2013 Subaru Legacy use a separate remote or a flip/smart key?
Aftermarket catalogs for these years show conventional keys with a separate wireless keyless‑entry remote, not flip or smart/proximity push‑to‑start keys.
Can I program a replacement Legacy remote myself?
Some older Subaru keyless‑entry remotes can be programmed with on‑board procedures, but many later systems require dealer or professional locksmith equipment for successful programming.
If I lose all keys to my Subaru Legacy, can a locksmith make and program a new one?
Yes. An automotive locksmith or dealer can cut a new key and, if equipped, program the immobilizer and remote using professional diagnostic tools.
Can you program a Legacy key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
