I THINK YOU HAVE A PROBLEM WITH YOUR PASSKEY SYSTEM The charging system or the starter is mostly likely your problem. I just went through this with my Cadi. What ended up being the problem was that the factory alarm within the car was starting to fault. The alarm had to be replaced and a new ignition cylinder, and new pass key. Answer Other posters are correct, the pass key system is malfunctioning intermittently. Over time the black plastic insert in the key wears out causing it to read improperly when inserted into the car. The pass key system then kicks in and shuts off the starter and fuel pump as a security precaution which leads to no starting. My Deville had the same problem so I took it to be tested at a GM dealership (has to be GM, others don't have the equipment) and they will make you an exact copy of the key for between $25 and $60 depending on the place you go to. The key should be replaced as soon as possible or the car may not start at all when the sensor cannot read the key code anymore.
