Hi everyone, this is my first post!! I ask for a help. Last month, I had a bad car accident, then I change some parts from front. I believe that all parts from OEM. Now my car has been fixed and running normal(I assume there are not more mechanical and electric problems . But there is only one issue, the security system seems downs.
Normally, if I press the "lock" button, the headlight will be flash with the beep. Now, I press the lock, the car is locked but without the flash and beep, and the security red light doesn't show up.
When I get the car back, I was asked for enter the radio code and I just Press and hold the power button for 2s like the manual say and works. But the security system is still down.
I am sure my car is locked. Please tell me what should I do? How could I re-activate the security system.
My car is RDX2013 Tech Package

Thank you!!!!!

 

Problem Solve: The hood latch sensor disconnected. Re-connect the wires and it works like usual.
