Step-by-Step Guide to Program Your 2005 Scion TC Key Fob
Follow these steps carefully to program your 2005 Scion TC key fob. Ensure you have all necessary components ready before you begin.
-
Start with the Driver’s Door Open: Make sure the driver’s side door is open and that the key is completely removed from the ignition switch. This is the initial step to get your Scion TC ready for programming mode.
-
Key Insertion and Removal (Twice): Within a 5-second timeframe, insert your key into the ignition switch and then remove it. Repeat this insert and remove action a second time. Speed is important here, so perform these actions promptly.
-
Door Close and Open Cycle (Twice): Within 40 seconds after the key insertions, close the driver’s door and then open it. Repeat this close and open cycle of the driver’s door one more time.
-
Key Insertion and Removal (Once): Insert the key into the ignition switch one more time, and then immediately remove it.
-
Door Close and Open Cycle (Twice Again): Within 40 seconds, once again, close the driver’s door and then open it twice, mirroring step 3.
-
Ignition and Door Closure: Insert the key into the ignition switch and close the driver’s door completely.
-
Select Programming Mode: This step determines whether you are adding a new remote, erasing old codes, or checking existing ones.
- Once (ON/OFF): Turn the ignition switch from the OFF to ON position and back to OFF just once. This mode is for programming an additional remote while keeping the currently programmed remotes active.
- Twice (ON/OFF): Turn the ignition ON and OFF twice to program a new remote and erase any previously programmed codes. Use this if you are replacing a lost remote.
- Three Times (ON/OFF): Turn the ignition ON and OFF three times to check the number of remotes currently programmed to your vehicle.
- Five Times (ON/OFF): Turn the ignition ON and OFF five times to erase all previously registered remotes.
-
Remove the Key: Take the key out of the ignition switch.
-
System Response: At this point, the vehicle’s system should respond by locking and unlocking the doors. The number of lock/unlock cycles will depend on the programming mode selected in step 7, indicating the system is ready for remote programming. It might cycle once, twice, or five times based on your selection, followed by a series of lock/unlock cycles (one to four times, slowly) to indicate the number of remotes currently registered.
-
Simultaneous Button Press: Within 40 seconds, press and hold both the LOCK and UNLOCK buttons on the key fob simultaneously. Release them after pressing.
-
Press Lock or Unlock Button: Within 3 seconds of releasing the buttons in step 10, press either the LOCK or UNLOCK button on the key fob you are programming.
-
Confirmation: The system should respond again by locking and unlocking the vehicle doors. A single lock/unlock cycle confirms successful programming. Two cycles indicate that the programming attempt has failed, and you may need to repeat the process.
-
Program Additional Remotes (Optional): If you have additional key fobs to program, repeat steps 10 through 12 within 40 seconds. You can program up to 4 remotes for your 2005 Scion TC.
-
Exit Programming Mode: To exit the programming mode, simply open the driver’s door.
