Viper 3305V Responder 350 2-Way LCD Security System

Up to 1/4-Mile Range

Viper rates the 3305V for up to 1/4-mile operating range under ideal conditions.

Actual performance depends on:

• Buildings
• Walls
• RF interference
• Antenna placement
• Installation quality
• Terrain

The 1/4-mile rating places the 3305V in Viper’s standard-range security category.

For shoppers who need substantially greater distance, Viper’s 1-mile systems may be a better fit.

For everyday parking lots, driveways and workplace parking, the 3305V offers useful range without moving into a more expensive long-range platform.

Stinger DoubleGuard Shock Sensor

The Viper 3305V includes the Stinger DoubleGuard shock sensor.

Impact sensing helps the alarm detect physical disturbances before a thief necessarily opens a door.

A properly adjusted sensor can react to activity such as:

• Window impacts
• Forced-entry attempts
• Body impacts
• Vehicle tampering

Shock-sensor calibration matters.

Set it too low and somebody can hit the vehicle without triggering an appropriate response.

Set it too high and a passing garbage truck can cause your alarm to announce that society has collapsed.

Professional adjustment helps find the useful middle ground.

Failsafe Starter Kill

The Viper 3305V includes Failsafe Starter Kill functionality.

When correctly installed, starter interruption adds another theft-deterrent layer by preventing normal starter operation under applicable armed conditions.

This is different from a factory transponder immobilizer.

The aftermarket alarm controls the starter circuit, while a factory immobilizer may use encrypted keys or electronic authorization through the vehicle’s ECU or body-control system.

Layering both can make a vehicle substantially less convenient to steal than simply relying on a siren.

For more on combining different security layers, see our guide to car alarms that protect your build.

Revenger Six-Tone Siren

The Viper 3305V includes Viper’s Revenger six-tone siren.

When an applicable alarm event occurs, the siren provides an audible warning designed to attract attention and discourage further intrusion.

The system can also flash the vehicle’s parking lights when properly connected.

That gives the alarm both:

• Audible warning
• Visual warning

More importantly, the 2-way remote can help keep you informed instead of leaving the siren to perform its solo concert in the parking lot.

Clone-Safe Code-Hopping

The Viper 3305V uses Clone-Safe Code-Hopping technology.

Rather than transmitting exactly the same fixed code every time a command is sent, code-hopping technology changes the transmitted code according to the system’s security logic.

The goal is to make simple code-capture and replay attacks more difficult than they would be with a basic fixed-code remote.

For a security system, that’s a meaningful feature.

A remote should unlock the car for you.

It should not make life easier for someone standing nearby with an RF recorder.

Keyless Entry Capability

The Viper 3305V supports remote keyless entry when properly connected to compatible vehicle power locks.

That allows the alarm remote to handle everyday lock and unlock functions in addition to security control.

Vehicle lock circuits vary significantly.

Some older cars use straightforward positive or negative trigger wiring.

Newer vehicles may route lock and unlock commands through a body-control module or vehicle data network.

Our Honda Civic car alarm wiring guide shows why vehicle-specific lock, unlock, ignition and trigger wiring must be correctly identified before installing an aftermarket alarm.

Parking-Light Flash

The 3305V provides parking-light flash output.

When connected properly, the vehicle’s parking lights can flash during:

• Arm
• Disarm
• Alarm events
• Other supported security functions

That gives you visual confirmation in addition to the remote feedback and audible siren.

It also helps identify which vehicle is actually sounding an alarm in a crowded parking lot.

Bright Blue LED Status Indicator

The included bright-blue status LED provides a visible indication that the vehicle is equipped with an aftermarket security system.

This serves two purposes.

First, it provides system-status information.

Second, it acts as a visible deterrent.

Someone looking through the window can see that the vehicle has an active alarm system before deciding whether they really want to make the next several minutes of their life more complicated.

Dome Light Supervision

The Viper 3305V includes dome-light supervision through an onboard relay.

When properly installed, the system can control supported interior-light behavior during security or entry functions.

This adds a useful convenience feature when unlocking or accessing the vehicle at night.

It also demonstrates that the 3305V was designed to be more than a basic siren-and-shock-sensor box.

Comfort Closure

The 3305V supports Comfort Closure on compatible vehicles.

Depending on the application and installation, Comfort Closure can interface with supported factory convenience functions such as closing windows or other accessories when the vehicle is secured.

Vehicle compatibility varies widely, and not every vehicle supports this function.

Additional wiring or modules may also be required.

Two Auxiliary Outputs

The Viper 3305V includes two auxiliary outputs.

These can be used by a qualified installer to control compatible additional functions or accessories.

Possible applications depend entirely on the vehicle and installation.

Auxiliary channels can be useful for custom builds, but they are not universal plug-and-play accessory buttons.

The installer must determine what the vehicle supports and how the output should be safely interfaced.

One 2-Way and One 1-Way Remote Included

The Viper 3305V includes:

• One 2-way LCD remote
• One 1-way companion remote

The primary LCD remote provides 2-way system feedback.

The 1-way remote provides convenient backup or secondary-driver control without the same feedback capability.

This is a practical combination because it gives the primary driver the premium remote while still providing a second transmitter for another driver or backup use.

Viper also currently lists the 7345V 2-way LCD remote as compatible with the 3305V, and the 7145V 1-way remote is also listed for compatible 3305V applications.

Does the Viper 3305V Include Remote Start?

No.

This is one of the most important distinctions for shoppers.

The Viper 3305V is a security and keyless-entry system, not a combined alarm and remote-start system.

It provides:

• Security
• 2-way LCD feedback
• Keyless entry
• Starter interrupt
• Shock sensing
• Siren
• Auxiliary outputs

It does not include onboard remote-start functionality.

If you need remote engine start as well as security, look at a system such as the Viper 5305V, 5308V, 5808V or 5908V instead.

Viper 3305V vs. 5305V

The Viper 3305V and 5305V look similar because both use a 2-way LCD platform and both offer up to 1/4-mile range.

The critical difference is remote start.

Viper 3305V

• 2-way LCD security
• Up to 1/4-mile range
• Keyless entry
• Shock sensor
• Starter kill
• Six-tone siren
• No remote engine start

Viper 5305V

• 2-way LCD security
• Up to 1/4-mile range
• Keyless entry
• Shock sensor
• Starter kill
• Six-tone siren
• Remote engine start included
• SmartStart compatibility

If you only want alarm protection, the 3305V is the simpler option.

If you also want to start the engine remotely, the 5305V is the appropriate step up.

Viper 3305V vs. 3308V

Viper also offers the newer 3308V 2-Way LCD Security System.

Both systems provide:

• 2-way LCD confirmation
• Up to 1/4-mile range
• Starter interrupt
• Impact sensing
• Six-tone siren
• Flashing parking lights
• Keyless entry

The 3308V is the newer-generation platform and adds current SmartStart Pro compatibility and Viper’s updated system architecture.

The 3305V remains especially relevant for:

• Existing installations
• Replacement systems
• Older inventory
• Drivers specifically searching for the Responder 350 platform
• Buyers looking for compatible replacement remotes

That distinction is important for SEO because customers often search by the exact older model number when replacing or repairing an existing system.

Does the Viper 3305V Have GPS?

No.

The 3305V does not contain built-in GPS tracking.

It is a traditional RF vehicle-security system.

GPS tracking requires separate connected hardware on systems that support those upgrades.

Does the Viper 3305V Have a Shock Sensor?

Yes.

The 3305V includes Viper’s Stinger DoubleGuard shock sensor for detecting vehicle impacts and disturbances.

Does the Viper 3305V Have Starter Kill?

Yes.

The system includes Failsafe Starter Kill functionality when properly installed.

This creates an additional theft-deterrent layer by interrupting the starter circuit while the system is armed under applicable conditions.

Does the Viper 3305V Control Door Locks?

Yes, when properly integrated with compatible vehicle power locks.

Some vehicles may require additional relays, modules or interfaces depending on their electrical architecture.

Professional Installation Recommended

The Viper 3305V interfaces with several important vehicle electrical circuits.

Installation may involve:

• Constant power
• Ignition
• Starter circuit
• Door triggers
• Door locks
• Parking lights
• Shock sensor
• Siren
• Starter interrupt
• Dome lights
• Auxiliary outputs

Professional installation is strongly recommended.

Incorrect starter-interrupt or ignition wiring can create a no-start problem that looks like a mechanical failure.

If that occurs, our engine cranks but won’t start guide can help separate security-related issues from ordinary fuel, ignition and electrical faults.
