Keyless Entry

Keyless Entry

Performs lock and unlock tasks without physical contact with the vehicle. Power door locks can be controlled from several feet away or even within a building using a remote fob. The fob emits a radio frequency that is digitally encoded to prevent frequency stealing so no one can enter into your vehicle without your wireless transmitter.

Dual Zone Shock Sensor

Dual Zone Shock Sensor

This shock sensor utilizes warning chirps for minor disturbances and will trip the alarm if it detects more serious impacts or disruptions. Most dual zone shock sensors have adjustable sensitivity to reduce false alarms or warnings. These sensors let would-be thieves know that your vehicle is equipped with an advanced alarm system and to keep away.

General Features

Security System Type
This indicates whether the product is a security car alarm product, remote start module, or a combo unit that offers security with remote start features.

Security: This means that the car alarm system is just that. No bells and whistles, just a car alarm system.

Remote Start: when installed, this allows the user to start a vehicle from a remote location. Remote start modules and security with remote start alarms often require an additional vehicle specific bypass module to complete installation.

Security with Remote Start: This means that the system incorporates both features listed above.

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.
Remote Start
If the alarm or remote start module has "Yes" for this value then the system has an electronic device that allows you to start your vehicle by remote control without actually being inside the vehicle or using the key. The remote start system supplies the vehicle with power and simulates a start just as if you were inside using the key. Select vehicles require additional accessories or immobilizer/bypass modules to use the remote start feature.
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.
Number of Vehicles Supported
Some higher end car alarm systems can support multiple vehicles. This is the number of vehicles that the works with.
Number of Auxiliary Outputs
The number of auxilary outputs that the car alarm system supports. These outputs are left over from the total number of channels. They can be used to add on other options or additional features to a vehicle.
PC Programmable
Custom, advanced programming options through one or more of the following: PC, Pocket PC, PALM Pilot, Valet SW or Remote Transmitter allows for advanced controls of your alarm's functions.
Smartphone Compatibility
These are the types of smartphone systems that the car alarm system is compatible with.
GPS Tracking
These car alarms enable a user to track the position of the vehicle using GPS satellites.

does all wires on this alarm have to be connected?
A shopper on Oct 3, 2014
Best Answer: No. You don't have to hook up all the wires if you don't want to. As long as you have the basics like power, ground, ignition switch and siren all others are optional.
