Scion xA key types & programming facts
2004-2006 Scion xA models in the US/Canada use a conventional mechanical ignition key paired with a separate wireless keyless-entry remote. Programming of the remote portion can be done via an onboard sequence using the ignition and driver’s door, without special tools. The key itself typically uses an immobilizer transponder that must be cut and programmed by a locksmith or dealer using appropriate equipment.
Key types used on the xA:
- standard metal key with separate remote (non-flip, non-smart) (2004-2006)
- transponder chip key (separate from remote) (2004-2006)

How we validate this guide
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. Reviewed for route and safety by Mohammad H. Abdelhadi, ALOA-Certified Master Locksmith.

Common questions
Does my 2004-2006 Scion xA use a separate remote or a remote-head key?
The Scion xA for these years uses a standard metal ignition key with a separate keyless-entry remote fob, not a remote-head, flip, or smart key system.
Can I program a replacement remote for my Scion xA myself?
Yes. The 2004 Scion xA remote can be programmed using onboard procedures involving the ignition and driver’s door, without a scan tool. Similar remotes for these years are often user-programmable.
Does the Scion xA key have a transponder chip that needs programming?
Key suppliers list transponder key replacements for the Scion xA, indicating the mechanical key includes an immobilizer chip that must be programmed by a locksmith or dealer.
Can you program a xA 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?
