Features and Specifications

Remote Confirmation (?)2-Way remotes let you stay in touch with your vehicle, confirming your commands (such as remote start, or arming your security system) either with an LCD screen on the remote, or using LED lights. Some 2-Way remotes also act as a security pager, letting you know your siren has been triggered, even if you are too far away to hear it. LCD Screen
Remotes (?)The number and type of remotes that come with the system. 1 Responder LC3 2-Way and 1 5-button 1-Way
Range (?)Viper systems use Radio Frequency (RF) technologies to communicate with your vehicle, and these technologies each have a typical operating range. Range varies by the technology used, but also because of environmental factors such as interference from other RF sources. Currently Viper systems with the longest range use Spread Spectrum Technology (SST) with range up to 1 mile. Up to 1 Mile
Security (?)Approximately 1.2 million vehicles are stolen in the U.S. every year and $1 billion worth of contents are stolen out of vehicles - so millions of vehicle owners have reached out to Viper security systems as a powerful deterrent against thieves and vandals.
Remote Start (?)Remote Start allows you to start your engine by remote control, allowing your vehicle's climate control system to warm up or cool down the cabin before you get in. Range is important with remote start (your vehicle might be parked down the street, or at the far end of a parking lot) and 2-Way remote start systems are preferred (because they confirm that your vehicle has started.)
Keyless Entry (?)Unlock your vehicle's doors with the push of a button on your keychain remote.
Trunk Pop (?)Viper systems with Trunk Pop can open your power trunk with the push of a button.
SmartStart Compatible (?)A Viper SmartStart module can be added to this system to make your vehicle SmartStart ready.
Encryption (?)Clone-safe, anti-Code Grabbing technology comes standard on every Viper system. SuperCode™
Domelight Supervision (?)A great safety feature: illuminates your vehicle's dome light for 30 seconds when you disarm your security system or unlock the doors of your remote start system.
Stinger DoubleGuard Shock Sensor (?)Each Viper security system comes standard with the dual stage Stinger DoubleGuard shock sensor, which detects blows or impacts to the vehicle and can discriminate light impacts from heavy ones.
Neo Revenger 6-Tone Siren (?)Light impacts result in WarnAway chirps from the Neo Revenger Siren, while heavier blows result in the full 120 dB 6-Tone sequence, designed to frighten away the would-be thief and call attention to the intrusion attempt.
Failsafe Starter Kill (?)Keep your car where you parked it with the Failsafe Starter Kill, an immobilizer designed to prevent hot-wiring.
Anti-Carjacking (VRS) (?)VRS is a user-operated anti-carjacking system. Once activated, if your vehicle is carjacked, 30 seconds later the siren will start screaming for help and the lights will flash. When the carjacker pulls over and turns off the ignition, the starter kill will activate, which should prompt the carjacker to then abandon your vehicle for eventual recovery.
Guaranteed Protection Plan (GPP) (?)GPP refunds your comprehensive insurance deductible up to $2,500 if your car is stolen within the first year after Viper is installed; $5,000 if it also has Viper Window Film!
# of Auxiliary Channels (?)Auxiliary channels are electrical outputs controlled by your keychain remote, which your installer can interface with systems in your car to allow you to operate them by remote control. Additional parts or labor will be required. 4


Responder LC3

Responder LC3

Responder LC3 is the amazing 3rd Generation of Responder SST, with one-mile range, an LCD screen that’s 20% larger – and our coolest industrial designs, with an upgraded user interface, 3 intuitive side buttons, and a mini-USB charging port for the built-in rechargeable battery.



SuperCode is the technology that defines the functionality of Responder and the intelligence that drives its advanced features. Its protocol encompasses software-based system signal encryption (replacing hardware-based Clone Safe Code-Hopping). Multi-car operation is designed into the SuperCode protocol, so users will have all of the possible operations for two cars controllable by one remote.

    When it works it's GREAT!!! But have been back and fourth to shop over 20 times in last 2 years. Can't get it to say "Intruder alert" once alarm is set off, key pad doesn't alarm me when alarm itself is set off. Doesn't cover my entire truck. Only nose & 2 of the 4 doors on vehicle.

    I had the 3303 installed by Performance Mobile Installs in Pensacola, Florida at the end of 2012. I've had it for about a month and a half and I love it. Everything works flawlessly and does exactly what it's supposed to do, thanks to a good quality product and an awesome installer. No glitches, intermittent operation or false alarms like what I've had with other brand systems in years past. The only issue I've had with this one is the screen on the two-way remote gets scratched-up rather easily. I work in a rough environment, and a replacement remote is far from cheap. Trimming down a piece of cellphone screen protector material to fit over the screen works nicely to help preserve it. If Viper were to offer some type of protective gear as an accessory for these remotes, I'd be interested.

    I had this alarm installed on my car earlier this month by a local shop. At this point I'm quite satisfied with the security that this system is providing even though my car only allowed half of the system to be installed For some reason according to the installer Viper Alarms hasn't caught up to my cars technologically yet. I didn't want the remote start because I didn't want anything interfering with the cars ignition system, I don't trust the By Pass Sensor that has to be used in order for the remote start on the Viper to work. Other than that I would have to say that I would recommend this system to someone in need of one, especially for folks that drive the same type of car that I have, a Cadillac CTS-V.
