It's probably just the key fob battery is dead. Replace it, and if that doesn't fix the problem, you'll have to reprogram it. Have a mechanic or dealer reprogram so the car and the fob can talk to each other. OR if you're somewhat handy, the owners manual (available on line) will show you how: it's really easy.

My Caddi, I can't put my key in the ignition and my security light is flashing.
