Computer problem
2002 Ford F150 6 cyl Two Wheel Drive Manual 100009 miles

I believe that my Anti-theft system has been trigerred and I have done everything I can possibly think of to fix it, including disconnecting battery to changing and checking fuses. How can I reprogram the reciever/transmitter?I have original keys to the truck with no damage to them.

Use the key to lock and unlock the door should deactivate the alarm
what do you have for problem?
With key in and or cranking do you have a security / theft light on or blinking

if not then its not an alarm issue

Central Security Module (CSM) enable/disable mode allows autolock feature to be turned on or off. To enter enable/disable mode, close all doors. Ensure ignition switch is in LOCK position. Perform the following steps within 30 seconds: Turn ignition switch from LOCK to RUN position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from RUN to OFF position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from LOCK to RUN position.
CSM module should chirp horn indicating CSM module is in enable/disable mode and ready to accept program changes.
Press power door lock switch UNLOCK button once to command CSM module to toggle autolock feature on or off. Press power door lock switch LOCK button once to enable/disable autolock feature. CSM module will chirp one time to indicate autolock has been disabled. CSM module will chirp once, followed by a longer chirp to indicate autolock feature has been enabled. Press power door lock switch UNLOCK button once, then turn ignition switch to OFF position to exit enable/disable mode. CSM module should chirp once to verify a feature change.
Cycle ignition key 8 times within 10 seconds and end in RUN position to enter program mode. Doors should lock and unlock to confirm program mode has been entered. Press any button on Remote Keyless Entry (RKE) transmitter(s). Doors will lock, then unlock to confirm programming. If door locks do not respond, press button again (3 times maximum) with same RKE transmitter. If door locks still do not respond, go to SYSTEM TESTS. Repeat procedure for additional RKE transmitters (4 maximum). If equipped with memory seats, ensure RKE transmitter(s) are programmed according to numbers on back of RKE transmitter(s). Turn ignition switch to LOCK or wait 5 minutes for system to exit program mode. All doors should lock, then unlock to confirm exit of programming mode. Check system operation.
