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
What FCC IDs are used for Scion xB remotes?
The provided sources specifically state HYQ12BBX for 2004-2006 and HYQ12BBY for 2008-2012.
Is the 2012 Scion xB key a transponder chip key?
A source for the 2012 xB lists a non-chip 315 MHz remote, so the remote is identified as non-transponder in that listing.
Do I need the year and part number to choose the right xB fob?
Yes. The sources emphasize matching the vehicle year with the FCC ID and part number for compatibility.
Can you program a xB 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.
