Intermittent problem with security system prohibiting vehicle from engaging starter. Vehicle starts after 2-3 minute wait.
Same security system issue however I have found that if you hammer on battery terminals, get into the car, wait for security light to go out. And it will start! I don't know why it works but it does. The problem is in the security system as I have a new starter and battery.

I was having the security problem some time ago but got it temporarily fixed with a replacement key without the chip. I'm not sure how that worked but it recently has been starting to fail again. Is there a shop in my area I can take it to? Thank you.
