What can you do if the anti theft system is engaged on a 2013 ford F-150 and it won't start?

If the anti-theft system is engaged on a 2013 Ford F-150 and it won't start, first try using the spare key, as the primary key may be malfunctioning. Ensure the key is properly programmed to the vehicle; if not, you may need to reprogram it using the ignition method or a professional service. Additionally, disconnecting the battery for a few minutes can reset the system. If the issue persists, consult the owner's manual or a professional mechanic for further assistance.
