Anti-theft system preventing vehicle from starting

This is normally due to an issue in the system, or you don't have a key fob that will disarm the system. Do you have the remote door lock button to disarm the system?

Here is a guide that will help with other ways to try and disarm it:

If you have the key fob, then I suspect it is no longer working so it may need a battery, or you may need a new one.

However, if none of this works then there is an issue with the system, so we need to check for codes and find out what is there.

If you have an issue, then there should be some codes as this is laid out in the manual that I attached below.

Please see the info attached and then we can go from there.
