Hello, Does the key start the vehicle? Can you drive it like normal? You likely have a security issue between the key and the passlock sensor, but it could be anything from the key to the engine control module. Passlock is a broad system, so diagnostics is notoriously brutal without scan tools. Basically, the system runs through 3 or 4 control modules and several sensors. Everything has to agree on the vehicle and key or you get these issues. If you can start and drive it, take it for Passlock system diagnostics. If you have another key, try using the other key first. Scanning for codes might give you some clues as well.
