How do you program a 2002 Cadillac Seville sts remote?

Answer 1

To program a 2002 Cadillac Seville STS remote, first, sit inside the vehicle with all doors closed and the key in the ignition. Turn the key to the "On" position (without starting the engine) and then back to "Off" five times within 10 seconds. On the fifth turn, leave the key in the "On" position; the locks should cycle to indicate programming mode. Press and hold the "Lock" and "Unlock" buttons on the remote simultaneously for about 15 seconds until the locks cycle again, confirming successful programming.
