This system is a passkey and doesn't need a relearn when this is changed it is automatic when the key is turned on your system has another problem this is getting to be a issue i would recommend installing a pro bypass module to eliminate the passkey system they work great heres a link

well its ignition disable theft deterent
Expert:  car tech replied 6 years ago.

then there is another problem in the system if the new cylinder didn't fix it thats why i recommended the pro bypass to elimate this system

it turns out that the new key cylinder has to be recut to match the chip 17.50 each of original keys
