Security Lock Flashing. Even when I lock with key it stops flashing but stays on. What is solution?

You are going to have to use the Key fob or remote alarm fob to go threw a set of lock and unlock procedure. Crank the car shut it off remove the key outside the vehicle at a distance of at least 30ft then lock the car, wait till it arms and the dash light blinks once this is active you want to unlock the car with the remote. If this one does not work do the same thing except when you unlock it do so with the key to re open after arming security.Also make sure you have both fobs or all remote fobs with you when you do this lock with one unlock with the other then vise, versa ok if you need any further help just ask also make sure your battery is fully charged and the terminals are clean this will affect a security system bad a low battery or low battery in the FOB's.
