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. None
Remotes (?)The number and type of remotes that come with the system. 2 4-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. 1,500 Feet
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.) Optional
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. Optional
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. 66-Bit
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.
# 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. 2

XR Plus

XR Plus

VIPER recently made a significant performance upgrade to the RF receiver section of many of our award-winning security and remote start systems. The new XR+ Extreme Range superheterodyne receiver has an improved sensitivity specification of between 3 dB and 6 DB, which equates to a measurable range increase on the order of 15 percent. It also offers improved image rejection for certain types of RF interference, resulting in improved reliability.

    I have no idea if you actually read these reviews. They are full of spam.. Please read Joe - Shenzhen City. It makes Viper look like a bit of a twat.

    I installed a sidewinder alarm from D.E.I on my 1996 ford aerostar van. It quit working properly in 2001 and D.E.I. sent me a brand new Viper 560xv in just a few days. Since then i have had it removed and reinstalled in my 1997 Ford Aerostar van. It has worked flawless since then. Great products and customer service..

    Had This 211HV system installed on my 2007 Camry about a month ago. It seems to work well but I did have some issues with the installation (Best Buy, Geek Squad). The installer left the valet switch (necessary if a remote needs to be replaced) behind a facia panel. I have also discovered that the parking lights DO NOT flash unless the headlight switch is in the position to disable the Daytime Running Lights. If the switch is in the Auto position, the parking lights simply don't flash. It's probably an installation error but I can live with it the way it is. Good product, less than good installation.

    works good on my 1999 Dodge Ram 1500 the installer Jason at Freeman in Hickory NC did a great job and people friendly I am well satified

  7. Shane - Louisville, KY1/2/2011

    We have this keyless entry system installed on a 1998 Mustang. It has always been reliable and we haven't had one problem out of it. I think that Viper did an excellent job when they put this wonderful piece of technology together. It has actually deterred theft on our vehicle!! I couldn't thank this company enough. I have recommended this product to alot of people.

  8. LLoyd-Alberta, Canada11/18/2010

    Have a similar unit to this, about 10 years old. Was installed in a 98 Chrysler Concorde, now am wanting to put it in a 2004 Concorde. Is it compatible, will the wiring system be similar. Been very happy with the operation over the last decade

  9. franklin tx10/14/2010

  10. Owanna Santo Dominigo, Dominican Republic10/3/2010

    I just recently had a problem with one of my remotes ( when I open the door all windows open too), but I have had my system on my 1998 Lexus 300 GS for about 10 yrs. without a single problem. Excellent product!

  11. Esther-Phoenix, AZ.7/5/2010

    More than 5 years with this alarm system and it has not gave up on me. Thankyou much for selling this long lasting products.

  12. Ted Meade4/29/2010

    I have had this system for about 7 years it has been flawless. If you want security and peace of mind beyond what the factory installs you get it with this.

  13. Paul-Johnson City, TN1/13/2010

    Rugged, durable and there is no living without it.

  14. Jay Giberson New Jersey3/14/2009

    I have had this on my 1995 mustang gt for a couple years now and its the only alarm that hasnt crapped out! I think the product is great i always feel confident parking my car, plus i receive a nice $40 credit on my insurance every year because of the alarm, so in time it will pay for itself!

  15. Mark - Texas3/3/2009

    211HV is a great addition for older vehicles with factory alarm system but no keyless entry. The system has outputs that arm and disarm the factory alarm when locking or unlocking, allowing for complete integration with the vehicle. The on board relays for lock/unlock and light flash are icing on the cake with this system. I immediately purchased a second system for my other vehicle. Awesome product Viper! Keep this system in your lineup, because none of you competitors offer both the arm and disarm outputs. Two thumbs up!

  16. TONY-CHARLOTTE ,NC2/24/2009

    I`VE HAD THIS ALARM FOR ABOUT 3 YEARS NO TROUBLE WHAT SO EVER , I KNOW IT`S OLD TECHNOLOGY BUT STILL .....

What Our Customers Say

Had this alarm installed in my Camaro z28 and could not be happier, my car has had two other alarms in the past and this is by far the best yet! No complaints, works great!

Daniel - Austin, Texas VIPER Color OLED 2-Way Remote Start + Security System

This product does everything you need, the best part is by the LED confirmation, you will know if your car starts. My husband has a remote start the dealership put in, and if you're not close to the vehicle to hear the horn beep, you're out of luck. I got this for my daughter last year and for me, and it works like a charm. You can't go wrong. The distance is great on it!

Cheryl - Cleveland, Ohio VIPER 1-Button 2-Way Plus Remote Start System

Best thing I ever put in a car. I live in Wisconsin where winter cold is colder than cold, it is great to walk outside and get into a warm car, windshield is clear of snow and ice, I bought and had it installed by Best Buy, it works great and the installer was very helpful and still is when I call with a quick question.
