Security light flashing, takes ten minutes to start

I purchased this vehicle from Colorado, summarized the vehicle was stolen and wrecked, I was aware of the vehicle and it had being stolen and found and returned by law enforcement after the joy ride. Ignition switch was replaced only because the key was so worn down I had to jiggle the key to get it out of the off position for sometimes 5 or 10 minutes, but the car always started with no security light issues. It started without fail until I replaced the switch it's been a year now with this issue. I am understanding that there is two different security systems for my car listed above. I asked which system do I have, is there something in the VIN that identifies the VAT system that is in my vehicle or does it even matter. The car did not come with a key fob, so did this car come with a key fob, the door s lock via power locks but the odd fact is that I have to hold the door lock button for two to five seconds before it locks. When it's time to unlock the doors just tap the unlock and it unlocks without that delay or having to hold the button like when you lock the doors for that two to three second delay.
