Review: Viper 5706V 2-Way Car Security with Remote Start System

Getting Started with Enhanced Vehicle Comfort and Security
If you’ve ever lived somewhere with harsh winters or sweltering summers, you know the pain of stepping into a car that’s either an icebox or an oven. I remember those days clearly, scraping frost off the windshield while shivering or waiting for the AC to kick in after the interior had baked in the sun all day. This kind of daily discomfort isn’t just annoying; it can make your commute miserable and even impact your safety by delaying visibility or concentration. Finding a solution that would allow me to warm up or cool down my car before I even got in was a major priority, and a high-quality remote start system would have made a world of difference back then.

Before diving into a specific product, it’s crucial to consider what you truly need in a car security and remote start system. This category of product is designed for vehicle owners who want the convenience of starting their car remotely to pre-condition the cabin temperature, as well as enhanced protection against theft and vandalism. The ideal customer often parks outdoors or in environments where comfort upon entry is important, and also has concerns about vehicle security. If you primarily park indoors in a climate-controlled garage and live in a very low-crime area with no concern for vehicle theft, you might not need the full suite of features a system like this offers and could perhaps opt for a simpler, remote-start-only unit or integrated factory system if available.

When considering a purchase, think about the following:
* Range: How far away do you need to be from your car to reliably start it or receive alerts? Consider obstacles like buildings, walls, and other vehicles.
* Transmission Type: Do you have an automatic or manual transmission? Manual transmission vehicles require specific safety features (like reservation mode) to prevent accidental starts while in gear.
* Security Features: Beyond remote start, what level of security do you need? Look for features like shock sensors, door/trunk/hood triggers, starter kill, and siren types.
* User Interface: How do you want to interact with the system? Do you prefer a simple one-way remote, a sophisticated two-way remote with an LCD screen, or smartphone control (SmartStart compatibility)?
* Installation: Are you planning a DIY install or hiring a professional? These systems can be complex, especially integrating with modern vehicle electronics. Factor in the potential cost and complexity of installation.
* Additional Features: Are there other conveniences you want, like keyless entry, trunk pop, or accessory control?

Considering these points will help you narrow down the options and choose a system that best fits your vehicle and lifestyle.

Introducing the Viper 5706V System

Enter the Viper 5706V 2-Way Car Security with Remote Start System. This product promises comprehensive vehicle protection combined with the convenience of remote engine starting. It’s designed to be a full-featured solution for both security and comfort. When you purchase the Viper 5706V, you typically receive the main brain unit, wiring harnesses, the 2-Way Responder LC3 LCD remote, a companion 1-Way remote, the Control Center (combining LED and Valet switch with the antenna), siren, and necessary connectors. Compared to earlier Viper systems, the 5706V features the updated Responder LC3 remote with its larger screen, improved icons, rechargeable battery, and SST (Spread Spectrum Technology) for extended range. It also incorporates Viper’s New Technology Platform advances, such as D2D serial data port and flex relays, simplifying installation compared to older models or less advanced systems on the market.

This particular Viper system is ideal for someone who needs maximum range, wants detailed feedback from their vehicle (like status and temperature), requires advanced security features, and potentially drives a manual transmission vehicle needing specific safety protocols. It might be overkill for someone only needing basic remote start from a short distance or who prefers a simple key fob without a screen.

Here’s a quick look at the pros and cons:

Pros:
* Impressive one-mile range with SST.
* Feature-rich 2-Way LCD remote (Responder LC3) with clear feedback.
* Includes specific safety features for manual transmission vehicles (MTS mode/Reservation mode).
* Offers comprehensive security features (shock sensor, triggers, etc.).
* SmartStart compatible for optional smartphone control.
* Advanced technology platform simplifies installation points.

Cons:
* Complex installation often requires professional expertise.
* Some users reported missing minor components (like a toggle switch) in their package.
* Antenna connection could be more secure on the Control Center unit.
* Requires a bypass module for most modern vehicles with immobilizers (additional cost).
* Documentation included in the box may be minimal, requiring online research.

Diving Deep into Capabilities: Features and Their Advantages

Having used the Viper 5706V for a significant period, I can attest to the power and convenience packed into this system. It’s the collection of features working together that makes it such a robust solution. Let’s break down the key aspects.

Two-Way Communication and One-Mile Range:
This is arguably the headline feature. The Viper 5706V uses SST (Spread Spectrum Technology) to achieve a claimed one-mile range. What this means in practical terms is reliable communication over considerable distances, even with obstacles like walls and buildings in the way. The “two-way” part is crucial – it means your remote *receives* feedback from the car. You don’t just send a command and hope it worked; the remote confirms that the car started, locked, unlocked, or if the alarm was triggered. For someone who parks far from their home or office, or in a busy area with lots of signal interference, this range and confirmation are game-changers. No more guessing if your car is warming up on a freezing morning.

Responder LC3 LCD Remote:
The main remote control, the Responder LC3, is a sophisticated piece of tech. It features a large LCD screen that uses Viper’s Priority icons and clear text labels. The icons are prioritized, with the most important ones (like lock/unlock/start status) being larger and centrally located. This makes understanding your car’s status at a glance much easier than with basic remotes. The text provides additional detail, like confirming a command or telling you *why* the alarm was triggered (“Shock Sensor” or “Door Open”). The remote is also rechargeable via micro-USB, which is incredibly convenient and saves on battery costs compared to systems using disposable batteries. Having a remote that not only tells you the car’s status but also confirms commands significantly reduces anxiety and improves the user experience.

Advanced Remote Start Functionality:
Beyond simply starting the engine, the Viper 5706V offers intelligent remote start features. For manual transmission vehicles, the Mandatory Manual Transmission Arming (MTS) mode with its “reservation mode” is a critical safety layer. You have to perform a specific sequence (leaving the car running, engaging the parking brake, removing the key, exiting, and letting the engine shut off) to arm the system for remote start. If a door is opened or the parking brake is disengaged after this sequence, remote start is cancelled, preventing accidental starting while in gear. This feature alone makes the Viper 5706V a top contender for manual car owners seeking remote start. The system also supports features like Runtime Reset (extending the engine’s run time) and Timer Start (starting the car at set intervals), adding further convenience.

Active Temp Check:
A fantastic feature tied into the remote start is Active Temp Check. Instead of the time, the LCD remote can display the actual temperature inside your vehicle. This is incredibly useful! On a cold morning, you can see the temperature climbing as the heater works, giving you an idea of when it will be comfortable to get in. Similarly, on a hot day, you can see the AC cooling things down. This eliminates guesswork and ensures you leave for your car at just the right time.

Comprehensive Vehicle Security:
The Viper 5706V is a 4-channel security system. This means it monitors multiple points: doors, trunk, and impacts (via the adjustable shock sensor). If any of these are triggered while the system is armed, the loud Revenger siren will sound, and crucially, your 2-way remote will alert you instantly with sound, vibration, and a message on the screen detailing the trigger. This immediate feedback is far more effective than a one-way system where you might not hear the siren or know what’s happening. The system also includes a starter kill feature (though some users noted issues getting this particular component, the *capability* is there), preventing the car from being hotwired. Silent Mode2 allows siren-less arming, where only the remote alerts you, which can be useful in quiet neighborhoods.

SmartStart Compatibility:
For those who want the ultimate convenience, the Viper 5706V is SmartStart compatible. This requires an optional SmartStart module and subscription, but it allows you to control and monitor your vehicle from your smartphone from virtually anywhere you have cellular service. Lock/unlock, remote start, GPS tracking (on higher tiers), and alerts can all be managed through the SmartStart app. While an added cost, it extends the system’s functionality far beyond the one-mile range of the remotes.

New Technology Platform Features:
Viper designed this system with installers in mind, incorporating features from their “New Technology Platform” to simplify the process. The D2D (Data-to-Data) Serial Data Port allows for plug-and-play connection with compatible XPRESSKIT interfaces (like immobilizer bypass modules), reducing the number of wires that need to be individually spliced. Virtual Tach eliminates the need to find and connect to the engine’s tachometer wire for remote start timing on many vehicles. Flex Relays onboard mean the system’s brain can handle many remote start and light flash connections directly, reducing the need for external relays. The Control Center combines the antenna, status LED, and Valet switch into one unit, often simplifying mounting and making the Valet switch easier to access when needed. While installation is still complex for a beginner, these features streamline the process for those with some experience or professional installers.

Overall, the combination of long-range 2-way communication, the informative LC3 remote, intelligent remote start (especially for manual transmissions), robust security features, and modern installation-friendly technologies makes the Viper 5706V a powerful and versatile system for enhancing vehicle comfort and security.

What Actual Owners Are Saying

Based on feedback from numerous users who have purchased and installed the Viper 5706V, the overall sentiment is very positive. Many rave about the impressive range, confirming that it works reliably even through buildings and over long distances in busy environments. The specific support and safety features for manual transmission vehicles are frequently highlighted as a major selling point that works effectively. Users appreciate the convenience of remote starting, particularly for pre-heating or pre-cooling their cars, and enjoy the array of additional programmable features available. However, a common theme is the complexity of installation, with many recommending professional help unless the installer has significant experience with car electronics and access to vehicle-specific wiring diagrams. Some minor complaints included potentially receiving a used key fob or finding that small, expected components (like a failsafe starter kill or a toggle switch) were missing from their package, requiring extra effort to acquire them. Despite the installation hurdle and occasional missing part, satisfaction with the system’s performance and features after installation is generally high.

Wrapping Up: Is This the Right Choice for You?

If you’re tired of facing extreme temperatures when you get into your vehicle or are concerned about its security, a quality remote start and security system is essential. Leaving those problems unaddressed means continued discomfort and the potential for vehicle theft or damage without immediate notification. The Viper 5706V 2-Way Car Security with Remote Start System stands out as an excellent solution for several reasons: its class-leading one-mile 2-way range ensures reliable communication and confirmation, its intelligent features like MTS mode make it safe and practical for manual transmission vehicles, and the detailed feedback from the LCD remote keeps you informed about your car’s status at all times. While installation requires expertise, the benefits provided by this Viper system make it a worthwhile investment for peace of mind and daily comfort.
