01 Dodge Neon ES

Okay, I was wondering if it had a wireless remote system. I bought the car, but it had been in a wreck previously so maybe they forgot to turn the remote over. It has a sentry alarm, trunk button inside the glove compartment, automatic locks and windows. I was wondering if they installed a factory wireless remote because the alarm goes off if you don't turn the key the right way, and I wanted to know if there was a way to check. Thanks
