Welcome to FTE mr.sofast

More information about what has been going on and who did the work would be appreciated. If the dealer worked on the truck I would be giving them a call.

If the dealer did the job then they should have re-programmed all the coding for new keys.

Seems like I read something in the manual about resetting the alarm with the red button on the key fob. Might be worth a try?
