Viper 3100V 1-Way Vehicle Security System

Up to 1/4-Mile Range

Viper rates the 3100V for up to 1/4-mile remote range under ideal conditions.

Actual range can vary depending on:

• Buildings
• Walls
• RF interference
• Antenna placement
• Installation quality
• Terrain and environmental conditions

For typical driveway, workplace and parking-lot use, the 3100V offers plenty of practical operating distance without stepping into Viper’s more expensive long-range systems.

Onboard Shock Sensor

The Viper 3100V includes an onboard impact/shock sensor designed to detect physical disturbances to the vehicle.

A properly adjusted sensor can help detect events such as:

• Vehicle impacts
• Window impacts
• Forced-entry attempts
• Tampering
• Significant body movement

This gives the system a way to react before somebody necessarily opens a door.

Shock-sensor adjustment is important.

Too little sensitivity and meaningful impacts may go unnoticed.

Too much sensitivity and the UPS truck driving past becomes a five-alarm emergency.

Door, Hood and Trunk Protection

When correctly installed with the appropriate vehicle trigger circuits, the Viper 3100V can monitor common vehicle entry points such as:

• Doors
• Hood
• Trunk or hatch

These trigger inputs allow the alarm to respond when a protected opening is accessed while the system is armed.

Exact wiring requirements vary by vehicle.

Older vehicles may use simple switched trigger circuits, while newer applications can require additional vehicle-interface hardware or integration with a body-control module.

Our Honda Civic car alarm wiring guide shows why vehicle-specific trigger and lock wiring must be identified correctly before installation.

Starter Interrupt

The Viper 3100V includes starter-interrupt functionality.

When properly installed, the system can interrupt the starter circuit under applicable armed conditions, making it harder to simply start and drive the vehicle away.

This provides another layer of protection beyond the audible alarm.

That layered approach is important.

A siren attracts attention.

A shock sensor detects impact.

Starter interruption makes unauthorized starting more difficult.

Parking-Light Flash

The 3100V supports parking-light flash output.

When properly installed, the parking lights can flash during:

• Arming
• Disarming
• Alarm triggers
• Supported security events

This provides visual confirmation in addition to the audible alarm.

It also makes it easier to identify your vehicle in a large parking area.

Six-Tone Security Siren

Viper’s current 3100V specification includes a six-tone siren.

When an applicable alarm trigger occurs, the siren provides a loud audible warning designed to attract attention and discourage continued tampering.

The siren works alongside:

• Shock sensing
• Starter interruption
• Parking-light flash
• Door-trigger monitoring

to provide a more complete security system than a factory lock remote alone.

Keyless Entry Capability

The Viper 3100V supports remote keyless entry when properly connected to compatible power door locks.

That allows the included Viper remotes to control:

• Lock
• Unlock
• Security arm
• Security disarm

from one transmitter.

Vehicle lock systems vary widely.

Some applications use simple positive or negative trigger circuits.

Others may require:

• Relays
• Lock-interface modules
• Data modules
• Vehicle-specific wiring

Professional installation is strongly recommended.

Viper 3100V vs. Factory Security

Many vehicles leave the factory with only basic security.

That may consist of:

• Power door locks
• Factory horn alarm
• Factory immobilizer
• Basic keyless entry

The Viper 3100V can add additional aftermarket protection including:

• Dedicated shock sensing
• Starter interruption
• Parking-light warning
• Dedicated alarm siren
• Aftermarket remote control
• Keyless-entry integration

For older vehicles in particular, that can represent a significant security upgrade.

Viper 3100V vs. Viper 3105V

The 3105V is the enhanced version of Viper’s 1-way security platform.

Both systems offer:

• 1-way control
• Up to 1/4-mile range
• Starter interrupt
• Shock sensing
• Six-tone siren
• Parking-light flash
• Keyless entry

The 3105V adds more advanced features, including Viper’s Stinger DoubleGuard shock sensor, Clone-Safe Code-Hopping, auxiliary outputs and an upgraded control-center architecture.

The 3100V is better positioned as the simpler and more affordable security option.

Viper 3100V vs. Viper 3305V

The biggest difference between these systems is communication.

Viper 3100V

• 1-way remote control
• Up to 1/4-mile range
• Basic security
• Shock sensor
• Starter interrupt
• Lower-cost platform

Viper 3305V

• 2-way LCD remote
• Up to 1/4-mile range
• Remote command confirmation
• Shock sensing
• Starter kill
• More advanced feedback

If you simply need basic vehicle security, the 3100V makes sense.

If you want the remote to confirm system status back to you, move up to the 3305V.

Does the Viper 3100V Have Remote Start?

No.

The Viper 3100V is a security and keyless-entry system.

It does not include remote engine-start functionality.

Buyers who want both vehicle security and remote start should look at systems such as the:

• Viper 5305V
• Viper 5308V
• Viper 5808V
• Viper 5908V

Does the Viper 3100V Have GPS?

No.

The base 3100V does not include GPS tracking.

Its primary purpose is straightforward aftermarket security and keyless-entry control.

Professional Installation Recommended

Viper strongly recommends professional installation for the 3100V.

Installation can require connections to:

• Constant power
• Ignition
• Starter circuit
• Door triggers
• Hood trigger
• Trunk trigger
• Parking lights
• Power door locks
• Siren
• Shock sensor
• Starter interrupt

Some vehicles may require additional parts or interface hardware.

Incorrect starter or ignition wiring can create a no-start condition that looks like an engine or electrical failure.
