This code is usually triggered when a not registered or damaged key is used to start the engine. When the starting operation is carried out five or more times consecutively with the same unregistered key, the system will lock.
If the problem occurs try disconnecting the car battery for about 30 minutes and then try starting the engine with a known registered key. If the problem persist you have to have the dealer erase the code and reprogram the keys again.
I have also see keys "die" after being to close to a strong electro magnetic field, in this case the owner worked near large generators and this wiped the memory from the key
