Hello and welcome to JustAnswer!

Security can be disarmed using the key fob or unlocking a door manually with the key, provided the system is fully functional, but it can't be removed from the vehicle.

The first step in diagnosing a no start condition is checking for fault codes. Have you checked for codes?

Does the key fob work?
