go to your dealer. It will cost you an arm and a leg for the key and fob and also to program it.

This definately sounds like the clutch cycling switch or the low pressure switch is bad. You just simply evacuate the system, screw off the old and screw on the new and then evacuate and recharge the system. This should get you fixed. You might also want to check and make sure that you have enough refirgerant in the system. If there is not enough then this switch will not allow power to flow to the clutch to prevent any damage to the compressor from there not being enough oil in the system.
