It sounds like the fob has lost connection with the central locking module. It can also be due to a faulty module or wiring issue.
First try to program the key to the vehicle and see if that will work.
Follow these steps:
Ignition switch to "run" position, try to start and let key return to "run" position
About ten minutes later security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of three relearns.
Turn key off, then start it.
Please let me know if this works.
