No holster. It has the ignition switch which will accommodate the sleeve key to use when the key fob battery is dead, etc.. But the I tried the sleeve key also with the same no start result. Even with the key fob in my pocket, the ignition switch engages, the dash lights up, the ratio comes on, the power windows/sunroof work, but, the engine won't start as it apparently is not getting fuel. It is still working fine now after it apparently rest, but, I'm concerned about the next time. This event has occurred twice in the last year.
