Add security

Viper's Model 3305V 2-way security system will deter most criminal attacks against your vehicle and the property you keep inside it — you'll feel safe and secure no matter where you park. The system includes a 2-way remote transmitter which reports your car's security status on its LCD screen. The system uses features like Starter Kill, which prevents hot-wiring, and a dual-stage shock sensor, which warns you if someone tries to get into your car. The system's 6-tone siren chirps an early warning in the case of an intrusion attempt, and then unleashes an ear-splitting blast if the intrusion continues, chasing away crooks and attracting attention. Whether you're sightseeing, dining out, or shopping, you can be sure that your car will be exactly where you left it.

Extended reach remote

Viper includes a control center in this security package that includes a valet switch, a bright blue LED status indicator that tells would-be thieves that there's a security system onboard, and a special RF receiver and antenna, which extends the range of the system's remotes to over a quarter mile. The system includes two remotes:  a 4-button 1-way transmitter, and the 2-way remote transmitter. Optional replacement remotes are available if you lose one or want a spare.

Important Note:
We offer a databus interface module that can save you lots of time when you install a Viper security system in most vehicles. Chat or call us at 1-888-955-6000 to see if the interface will work with your vehicle.

If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this security system yourself. If not, please consider having your system professionally installed by purchasing an InstallCard.

To ensure vehicle compatibility, please enter your vehicle information in OutfitMyCar. Your order will be reviewed by our Care Experts group, who will contact you if further information or recommended accessories are needed.

Product Research


Overview: The Viper Responder 350 2-way car security system, Model 3305V, will protect your vehicle with the most up-to-date electronic technologies available, including the Stinger DoubleGuard shock sensor, the Revenger six-tone siren, and the Failsafe Starter Kill. The system comes with one 4-button 2-way LCD remote and one 4-button 1-way remote. The system features 2 auxiliary outputs to provide keyless entry and other convenience features, and is covered by a limited lifetime warranty.

ESP2: The Viper Model 3305V features ESP2, Viper's exclusive serial communications protocol that allows extra ultra security, high-speed communication between systems, and enables many of Viper's key features.

Clone-Safe Code-Hopping: To prevent the unauthorized cloning of the remote's transmitter, the receiver and remote controls each use mathematical algorithms to change their codes each time the remote is used. The control unit knows what the next codes should be, even if you use the remote control out of range of the vehicle or the battery has been removed. Should the remote and control unit ever get "out of sync", you can easily re-sync the remote by pressing the "lock" button several times within range of the vehicle.

Failsafe Starter Kill: To prevent your vehicle from being stolen, the control unit has a built-in relay which will disable the starter. The Automatic Engine Disable (AED) feature, when programmed "on," disables the starter 30 seconds after the ignition is turned off. To start the car, it will be necessary to disarm the system with the remote control.

Revenger Siren: The Model 3305V includes the Revenger Soft Chirp siren (model 514LN). It consists of six different tones in sequence. Tones 2 through 6 can be eliminated by cutting the black/white wire loop, resulting in a single tone siren. The siren chirps can be either full volume or six decibels quieter than the 120dB full alarm blast.

Stinger Double-Guard Shock Sensor: The system features the Stinger Double-Guard Shock Sensor, which is designed to pick up impacts to the vehicle or glass. The sensitivity of the shock sensor is adjustable on the control module. When the sensitivity is set, a light impact will generate the "Warn-Away" pre-warning chirp of the siren. A harder impact will trigger a full alarm blast.

XR Plus: The remote and control unit utilize Viper's exclusive XR Plus technology, with Super Heterodyne Extreme Long Range receiver technology. To enhance the range of the remote controls, a separate plug-in antenna is included with the alarm. The working range of the system is approximately 1500 feet.

Remote Controls: The Model 3305V includes two remotes: a 4-button 2-way LCD remote and a 4-button 1-way remote. The 2-way Responder remote has an interactive display which provides feedback from the alarm so you get instant confirmation of commands as well as alerts. The 2-way remote operates at 434 MHz, and can be programmed for multiple response feedback settings. The buttons fully control the following features and functions of the security system:

  • Lock Button: Locks the doors and arms the vehicle
  • Unlock Button: Unlocks the doors and disarms the vehicle
  • AUX Button: Activates Silent Mode and Auxiliary Output functions
  • Red "Asterisk" Button: Panic functions
  • Combination: combining Lock and Unlock buttons together will control an Auxiliary Output

Active vs. Passive Arming: You can activate or arm the system by pressing the Lock button for one second (Active Arming). The system will respond with a short siren chirp. If you have connected the vehicle's power door locks to the system, the doors will lock. The system can be programmed to arm itself automatically (Passive Arming). If programmed for passive arming, the system will arm 30 seconds after the ignition is turned off and the system detects that you have left the vehicle by opening and closing a door. A warning chirp is sounded 20 seconds after the last door is closed to indicate the system is about to arm. At the 30 second mark, the parking lights will flash to indicate the system is armed.

Auxiliary Outputs: Convenience options, such as remote control trunk release and window automation, are available through the system's two auxiliary outputs. One function is controlled by pressing the AUX button, while the other is controlled by pressing Lock and Unlock buttons together.

Silent Mode: The Silent Mode allows you to temporarily turn off the arm or disarm chirps. When in the Silent Mode, the Warn Away response to lighter impacts is bypassed, however, the alarm remains fully capable of triggering a full alarm.

Control Center: The alarm includes a self-adhesive Control Center which serves multiple purposes. The control center houses the system antenna for receiving commands from the remotes. It also contains the Valet button and a bright blue status LED. It connects to the Control Module via a ribbon cable, and is typically adhered to the upper part of the windshield.

Dome Light Control: When you disarm the alarm, the system will activate the dome light inside the vehicle for approximately 30 seconds. In addition, you can set the system to turn on the dome light when the ignition is turned off. This feature can be programmed on or off.

Valet Mode: You can prevent the system from automatically arming and triggering by using the Valet Mode. This is very useful when washing the vehicle or having it serviced. In Valet Mode, the security system will not arm, even with the remote control, but all convenience features (door locks, trunk release) continue to work normally.

Power Door Locks: The system will interface with negative-switching and positive-switching factory power door lock systems. When interfacing with any other type of factory door lock systems, or when adding aftermarket actuators, two relays (such as 120E5000) or item 607451M will be required. If your vehicle requires the use of a Data Integration module that controls your factory door locks, no extra parts, besides the Data Integration module, will be required.

Nuisance Prevention Circuitry: The Nuisance Prevention Circuitry (NPC) prevents annoying repetitive trigger sequences due to faulty door pin switches or environmental conditions, such as thunder, jackhammers, airport noise, etc. If the alarm triggers three times within a 60 minute period, and each time the same sensor or switch triggers the alarm, the NPC ignores, or bypasses, that sensor or switch (along with any other sensors or switches sharing the same zone) for 60 minutes.

Vehicle Recovery System (VRS): The VRS feature is designed to ensure that any unauthorized user of your vehicle (even if using your keys and remote control) will not be able to permanently separate you from your vehicle. After the ignition is turned on, you can arm the VRS with the remote. Once armed, the system will initiate the following sequence if any door is opened and closed:

  • 15 Seconds after the last door has closed, the system status LED begins flashing (to give you time to distance yourself from your vehicle in the event of a carjacking).
  • 45 Seconds later, the siren begins chirping and parking lights begin flashing.
  • 15 Seconds after the siren chirps begin, the siren's output changes to a full blast. From this point on, when the ignition key is turned off, the VRS will immediately turn on the starter kill feature, preventing the vehicle from being restarted.
  • 3 Minutes after the constant siren begins, the flashing parking lights and the siren will stop, and the starter kill remains active until the system is disarmed. If the door is opened or ignition is turned off and on in an attempt to restart the car, the siren and light flashing will begin again.

Power Saver Mode: The system will automatically enter the Power Saver Mode while it is armed or in the Valet Mode, after a period of time in which no operation has been performed. When the system is armed, Power Saver mode begins after the system has been armed for 24 hours, and the LED will flash at half the normal rate. In Valet Mode, the LED will shut off if the vehicle is not used in one hour. Power Saver Mode lowers the current draw to the vehicle's battery.

Optional Accessories: The Viper Model 3305V can accept a wide range of convenience and security accessories from Viper and XpressKit:

  • SmartStart: The Viper SmartStart module lets you start*, control, or locate your car from virtually anywhere with your smartphone. Available SmartStart modules include the VSM200, VSM250, and VSM50BT. (*separate remote start system required)
  • Additional Remotes: Replacement or additional 7145V remotes for Model 3305V.
  • Field Disturbance Sensor: The XpressKit 508D Field Disturbance Sensor detects movement inside or just outside of your vehicle.
  • Audio Sensor: XpressKit 506T for glass impact audio detection.
  • Tilt Sensor: XpressKit 507M to monitor the tilting of your parked vehicle (caused by an attempt to jack up or tow your vehicle)
  • Ultrasonic Sensor: XpressKit 509U to monitor the airspace inside your vehicle to detect subtle window tampering.
  • Siren with Backup Battery: XpressKit 515R for an optional siren with a battery backup.

great alarm for the price

Written By keV72362, Newport Beach, California on Thursday, January 22, 2015

I have a 2002 Toyota Tacoma the only thing I don't like is if you want the doors pop open when you hit the alarm to lock it it's an extra $100 per door which i think is a bit expensive and should be included with the installation not an extra fee that's ridiculous that its a extra hundred dollars per door

Pros: price of the car alarm its a good deal you get a lot for money I like that feature of the Screen

Cons: If you Bump your car alarm doesn't go off I don't like that feature

five stars

Written By Kev72362, Newport Beach, California on Tuesday, January 06, 2015

Love it just bought it I haven't had it that long enough to really give it a great review but so far so good

Pros: Nothing. haven't had it that long to really tell if its a good car alarm but so far so good

Cons: I bought the Viper alarm at another retailer. The price included the installation. what I didn't like is you have to pay extra for the automatic door locks. I don't think that's right.

Crutchfield Customer Review (What's this?)

Remote wit display has short battery life, installation is not user friendly, and interface for 2004 Jeep Liberty is far from simplified!

Pros: Looks good!
