How to Program a Keyless Entry for a Scion tC

by Stephen Ip

According to Edmunds.com, the Scion tC was introduced in 2005 by Toyota. Owners of the Scion tC can buy replacement keyless remotes for their vehicles at Scion or Toyota dealerships or online. The dealership can program factory-branded remotes at the time of purchase, but this is usually more expensive. Third-party remotes cost less, but you must program them before you can use them.

1

Insert and remove the key from the ignition twice in five seconds with the driver's door open. Close and open the driver door twice within 40 seconds. Insert and remove the key from the ignition. Close and open the driver's door within 40 seconds. Insert the key into the ignition and close the driver's door.

2

Turn the key in the ignition to the "On" and "Off" position once to program new remotes without erasing the current code for existing remotes. Turn the key to the "On" and "Off" position twice to erase the current remote code in preparation for programming new and existing remotes. Turn the key to the "On" and "Off" position three times to check how many remotes are currently programmed or five times to reset all remotes currently programmed.

3

Remove the key from the ignition. The door locks will cycle quickly one, two or five times to indicate the programming mode chosen. If the mode chosen previously was to check how many remotes are currently programmed, the door locks will cycle up to four times slowly to represent the number of remotes currently programmed.

4

Press and release the "Lock" and "Unlock" buttons simultaneously on the driver's-side door panel within 40 seconds after the door locks cycle. Press and release either the "Lock" or "Unlock" button on the remote being programmed within three seconds. The door locks will cycle once to indicate programming was successful or twice to indicate programming failed. If programming was unsuccessful, start again at the beginning of this step. Repeat these steps to program additional remotes. You can program a total of four remotes to operate with a single vehicle.

5

Open the driver door to exit the remote programming mode. Test each remote by locking and unlocking the door locks of the Scion.
