Best to have the system scanned for codes
an OBDII reader will get some codes but not all
need a scanner

Thanks.I am sorry I did not say more.I can start the truck after I wait for 10 mins after the securty light stops flashing. What can I do to REPAIR this.I would like to sell this truck in the future and would feel bad to just pass this issue along.

Possible problem is the ignition switch/lock
codes should help in pin pointing the problem
Momentarily rotate ignition switch to CRANK position, but do not start engine. Release switch to RUN position, but do not turn off. Wait 10 minutes and observe SECURITY indicator.
NOTE:Ensure battery is fully charged before proceeding. Ensure steps are followed in correct order or procedure may need to be repeated.
If passlock sensor was replaced, SECURITY indicator will flash for 10 minutes. If passlock module was replaced, SECURITY indicator will flash for a few seconds, then remain on for 10 minutes. If VCM was replaced with a new programmed VCM and connected to vehicle for the first time, vehicle will start and this procedure is not necessary. If replacement VCM was connected to any vehicle at any other time, SECURITY indicator will flash for a few seconds, then remain on for 10 minutes.
Of ignition remains on, SECURITY indicator will transition from flashing on briefly to off after 10 minutes. Turn ignition off and wait 10 seconds.
Repeat programming procedure 2 more times. New security code is ready to be communicated. New password is learned on next ignition switch lock cylinder from OFF to CRANK to ON.
