General Features

Car Alarm
If "Yes", the system will have alarm security features to help prevent vehicle theft and tampering. Remote start modules without alarm features will have "No" for this value.
Keyless Entry
Keyless entry allows you to remotely lock, unlock, and open the trunk of a vehicle if that is equipped with power door lock motors (actuators) and power truck motor (solenoid). Door lock controls via the remote are found on nearly all of today's car alarms.
2-way Paging
Alarms with 2-way paging inform the user via remote vibrating/audible/visual alert when the alarm is triggered. The pager must be within range to receive the transmitted signal.
Number of Remotes
The number of remotes included with the alarm system purchase.
Number of Buttons on Primary Remote
The amount of buttons on the Primary Remote generally equals the number of functions that you can use your remote for. Some remotes have auxiliary buttons which can perform more than one task per button.
Main Transmitter Type
LCD and OLED transmitters display various screen savers, warnings, alerts and other features on the face of the remote, rather than first generation button-only transmitters. They provide more information typically and other features.
Sidekick Remote Transmitter Type
Some car alarms and remote start systems come with more than 1 transmitter, which is referred to as the "sidekick" transmitter. Most LCD/OLED systems come with a button-only sidekick transmitter, while select units come with an additional LCD/OLED transmitter.
LED/Display Color
The color of the LED indicator(s) on various items such as button-only car alarm transmitters, various chargers, cell phone accessories and other products.

For OLED or LCD car alarm remotes/transmitters the display color refers to the color(s) of the screen.
