On first start turn the key and the vehicle goes totally dead, no lights, chimes etc

Hi,

This sounds like one of two things. However, I want to clarify what it is doing. When you say the vehicle goes dead does this mean the lights do not come on and the key does nothing when you turn it? Does the theft light remain on?

I think the best thing to do is get a video of what it is doing and post it here so we can actually see it.

Let me know thanks.
