My Daughters 03 F-150 can't be unlocked with the key or the alarm will go off, the only way to stop the alarm is with the remote. The remote is wearing out so instead of buying a new one she would like to use only the key. You can lock the doors with the remote or from the switch on the arm rest but when you unlock a door with the key the alarm goes off. Any help to use key only would be appreciated. Thank you.
