This is the second time this has happened to me now. I go to start my car and I get all the electronics/power/etc. but when i turn the key to start nothing happens. The first time this happened I had to have the car towed to a local shop where they claim to have "reset the security system". The car then started fine for a week (I would estimate 15 or more starts) and then today the same situation happened. I haven't had the car towed or anything since its at my house. I was hoping that someone here could help me diagnose the problem.

I have tried:
1. disconnecting the battery for xx minutes
2. lock/unlock from all locations
3. start the car in N and P
4. kick the tires....

BTW: When i turn the key to the run position, I can hear the fuel pumps come on (slight buzzing/hissing sound)

Is it possible to "reset the security system" as the local mechanic tells me or are they lying to me.

Please help, this is SO frustrating, I don't even have 1000 miles on the car since i bought it and I've had multiple problems. TIA
