Hi, my name is***** sounds like your car battery is dead. Try jump starting the car. If the battery is dead your remote won't work and you won't be able to turn the key in the ignition but the alarm will sound because it has a separate battery. It's also possible that your key is bad. If you have a spare key you should try that also.

Let me know how you make out.
