Crumpy's SRT was parked in the lot, Not locked and yet,

The alarm system went off. So I went out and put the key in the ignition, turned the motor and it went off. Strange event? Maybe I just happended to have hit the panic button withthe key fob in my pocket.... I shouldn''t be worried.

Well not exactly. You see, the car doesn't have an alarm system.

Noise like a bumble bee near the driver's side at the firewall.

Any ideas?
