What year ranges does this guide cover for the Scion TC Key Fob?

This guide covers the source-backed year clusters: 2005 and 2007; 2006 and 2008u20132009; 2010; 2011u20132012; and 2013.

Does this guide program only the remote portion, or also the transponder?

The guide is for on-board remote registration steps. Transponder, immobilizer, and smart key system programming are separate and may require professional equipment.

What if the Scion TC Key Fob steps do not work?

Repeat the correct year-cluster steps with strict timing, replace the remote battery, and confirm mode selection where applicable. If the vehicle cannot enter programming mode or failure confirmations repeat, professional support is appropriate.

When should DIY stop and professional help start?

DIY should stop when remote registration repeatedly fails, when key cutting is needed, or when smart key system equipment is required beyond on-board steps.

Can a replacement remote still be used with the Scion TC Key Fob process?

A replacement remote can often be registered if it matches the vehicleu2019s system and year cluster. If compatibility is uncertain or immobilizer-related work is required, a professional can confirm requirements before authorization.

Scion tC key types & programming facts

2005-2013 Scion tC models in the U.S./Canada use a remote-head key that combines the mechanical ignition/door key and a built-in keyless entry remote, with an embedded transponder chip for the immobilizer. Programming typically involves cutting the new key to match the existing locks, then registering the transponder chip and remote functions to the vehicle using onboard procedures or a capable scan tool, depending on equipment and locksmith/dealer practices. Owners are usually advised to have at least one working master key present for programming and to use an automotive locksmith or dealer for reliable results.

Key types used on the tC:

remote-head key with embedded transponder chip (mechanical blade + built-in 3‑button remote) (2005-2013)

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

What kind of key does my 2005-2013 Scion tC use?

It uses a 3‑button remote-head key with a built-in transponder chip for the immobilizer and a mechanical blade for the ignition and door locks.

Can I program a replacement Scion tC key myself?

Some owners report onboard programming for remotes, but the transponder chip generally must be programmed with dealer or automotive locksmith equipment for proper starting and security.

Is there a specific FCC ID I should match for my Scion tC key fob?

Many 2005-2013 Scion tC remote-head keys list FCC ID MOZB41TG; you should verify the FCC ID on your existing key or by VIN before ordering.

Can you program a tC 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.
