2002 Ford F150 Four Wheel Drive Manual 104000 miles
----------------------------------------------------------------
My truck has a factory installed alarm that recently quit working. This also includes locking my truck with my alarm remote. I have replaced the battery in the remote but that did not fix it.
HELP

Try to reprogram the transmitter

REMOTE TRANSMITTER
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.
