If your vehicle is being tampered with, your remote transmitter will warn you and set off the vehicles alarm.

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.
For OLED or LCD car alarm remotes/transmitters the display color refers to the color(s) of the screen.
A dual zone shock sensor is a feature of proximity and shock sensors only. Zone 1 ( light impact on shock sensor and short motions(adjustable) on proximity sensor) will trigger warn away chirp to warn intruder that car has an alarm without setting off the full alarm. Zone 2 (heavy impact on shock sensor and extended motions(adjustable) on proximity sensor) will trigger the alarm to “go off”.

Just like anything. Once installed correctly the product will work properly. Installed it on a 2014 Sonata using a DBALL2 for convenience and works perfectly. Saved me some time by not having to hookup the tachometer signal wire, door locks, alarm or even trunk since it does it all through the data wires. Could it have been done without the bypass? Sure. But the convenience and the price simply make it worth it.

Have installed a dozen or so of these and they are, by far, the best deal for a two-way remote start. Good range and works great with the DBALL2.

I know I can find out the temperature of the inside of my car, but I don't know what the light levels mean.
on the grey viper plastic (easily breakable) do you carry them and how much to replace them?
Unfortunately we do not have the remote you Specifically seek, the Clifford 7251X . However, Current Viper Remotes are often backwards compatible with their systems. We ask that you contact the manufacture, with the Model number of your system, and they will provide an RPN for the compatible remote(s), link below.
