OEM "Add-on" Remote Start

OEM Add-on remote start systems use the vehicle's pre-existing remote control system to start the car, and therefore does not include remotes or an antenna. Once installed, the user will push a simple sequence of buttons on the factory remote to start the car (e.g lock x 3, or lock-unlock-lock).

Benefits:

• This type of system will not require carrying an additional key fob for operation (this is especially relevant for vehicle that have the key built into the key fob)
• This system is typically less expensive than other types of systems

Limitations:

• Since the system works off of the factory keyless entry system the range of operation is limited to the range of the factory system, which is usually only a couple hundred feet.
• Some vehicle makes (e.g. Honda, Toyota) have a keyless entry systems that are disabled if the vehicle is running.  This means that if you remote start your car, you will have to use the key to manually unlock when you get in. 

1-Button Remote Start

These kits use a simple dedicated 1-button remote to start the car.  The remote is typically small and easy to use.  In most cases, this type of system functions only as a remote starter, but with some vehicles they can be wired to unlock the doors when the button is held down.

Benefits:

• Increased range of operation compared to the "add-on" systems
• Simple operation with minimal "clutter" added to your key chain

Limitations:

• 1-button keyless entry function does not work in all vehicles.

2-Way Remote Start

• These systems usually have a long range of operation

Limitations:
