Installed a new battery and now the car won't start, crank, radio won't turn on. Fuses were checked as good. Lights work, horn works, you can set off the alarm, but car won't even crank or make noise of any kind when you try to start it.
Do you
have the same problem?

It sounds like you have a bad connection at the battery even if the security was on it would not cut power to the radio. Please confirm the battery terminal connections here is a guide.
