A car starter is an electric motor that is used to turn the engine over in order to get it started.
The battery might be dead, or your engine might not work. *EDIT* Check your ignition coil, or starter solenoid, instead of saying "your engine might not work". If you take a hammer and tap the starter when somebody else is cranking the vehicle then you need a new starter.
the starter may be worn on your car if it starts up easily when its cold but slowly turns over when it is at the operating temperature. Replace the starter to your engine.

The starter should only be making noise if you attempt to start the car and the starter is going bad. It is possible that the remote starter is bypassing the mechanical starter. Starters are very easy to replace. Be sure to disconnect the car battery before doing so.
