Scion Key Specialist
Same-Day Service

Yes, for all Scion models from 2004 through 2016. Scion used Toyota's immobilizer system across the entire lineup, which means programming works through Toyota Techstream-compatible OBD-II tools. For add-key situations on pre-2011 models, a working master key is needed. For all-keys-lost situations, we use a PIN code obtained through Toyota TIS, which is available to certified locksmiths. The tC, xB, xD, FR-S, iQ, iM, and iA are all serviceable on-site without a tow.

Key-won't-turn is the most commonly reported key issue on Scion tC models across both generations, 2005 through 2016. The most frequent causes in order are a locked steering column from wheel position, which releases by gently rocking the wheel while turning the key, a worn key blade that no longer properly engages the ignition cylinder, and ignition switch failure on higher-mileage 2011 through 2016 models. The tC ignition lock cylinder has a known design tendency toward binding on both generations. If the steering column release does not work and a spare key does not work either, the cylinder itself may need replacement.

This is a well-documented Scion tC problem. Many aftermarket switchblade key conversions sold online require transferring the original transponder chip from the factory key housing into the new switchblade housing. When owners do this transfer themselves, the fragile chip often snaps or loses contact, disabling immobilizer communication and leaving the car unable to start. The car will crank normally but not fire because the ECU is not receiving a valid transponder signal. A new OEM-compatible key cut and programmed to your vehicle is the correct solution. We carry the right blanks and handle the programming on-site.

The FR-S shares its platform with the Subaru BRZ but follows Toyota's OBD-II key programming architecture. FR-S keys use ID4D transponder chips with FCC ID NI4TMRF815 on base trims, and optional push-button start proximity fobs with FCC ID HYQ14FBA on equipped models. Programming the FR-S uses Toyota Techstream-compatible tools and a VIN-linked PIN for all-keys-lost situations, the same approach as the tC but with different key profiles. It is more straightforward than actual Subaru BRZ key work because Scion kept Toyota's programming structure.

No. Scion was discontinued in 2016 but Toyota dealers continue to service all Scion models because they were always Toyota vehicles underneath. The key systems, programming tools, and OEM parts are all Toyota inventory. Your Scion tC, xB, xD, or FR-S is serviced exactly the same way as the Toyota equivalent, which means any qualified locksmith with Toyota Techstream access can handle key programming without a dealer visit or a tow.

First-generation xB models from 2004 through 2006 have a documented pattern of body control module glitches and occasional wiring chafing that causes intermittent keyless entry range loss. The fob may work fine close to the car but fail at normal distance, or fail and recover randomly. A fob battery too weak to sustain reliable signal is the most common cause and easiest first step. If a fresh CR2032 does not fix it, parasitic electrical draw from aftermarket accessories or a failing trunk light switch are common secondary causes on this generation. A BCM scan for receiver fault codes will identify whether the issue is vehicle-side.

The push-to-start tC from 2011 through 2016 and the FR-S use Toyota's smart key system. If the dashboard shows Key Not Detected, replace the CR2032 battery in the fob first. If the battery is good, hold the dead fob with its flat or logo side directly against the Start/Stop button, press the brake, and push the button. The button contains an antenna coil that can read the fob's transponder passively without any battery power. This method works consistently on all Scion push-start models. Use the hidden blade in the fob to unlock the driver's door first.
