1. Viper 4706V 2-Way LCD: Best Overall
The 4706V is the system to buy if you park out of sight. Its two-way LCD remote confirms that the car actually started, and Viper rates it for up to 1 mile. It can also show the cabin temperature on the remote, so you know when the car is warm. The remote is rechargeable over micro-USB, and a smaller one-way companion fob is included for a second driver. It is remote start only, without an alarm.
Key specs
- Type: 2-way LCD plus 1-way companion remote
- Range: up to 1 mile (Viper rating)
- Features: cabin temperature on remote, runtime reset with warning, 4 auxiliary outputs
- Rechargeable Li-ion remote; works with Viper SmartStart app add-on
- Install: professional; most modern vehicles need a bypass/data module
👍 Pros

👎 Cons

What owners say: Owners like the range and pre-heating their car from inside, while some were caught off guard that a bypass module was not included or that their installer would not install an online purchase.
2. Compustar CS4900-S: Longest 2-Way Range for the Money
Compustar rates its CS4900-S two-way LED system for 3,000 feet, and it includes a free 30-day DroneMobile trial if you want to add phone control. Compustar offers a lifetime limited warranty on the module, but only when it is bought and installed through an authorized dealer, so ask your installer before you order. A kit version is sold with the bypass module included.
Key specs
- Type: 2-way LED (CSX4900-S version adds smartphone control)
- Range: up to 3,000 ft (Compustar rating)
- Kit versions include a bypass module

What owners say: We found limited detailed owner feedback; installers generally recommend Compustar for reliability when it is dealer-installed.
3. Viper 5706V: Best Remote Start Plus Alarm
If you want security as well as warm-ups, the 5706V combines a two-way LCD remote start with a full alarm: a six-tone siren, starter interrupt and keyless entry. Its five-button remote controls up to 24 functions across two vehicles, and onboard relays reduce the extra parts many installs need. Check Viper’s fine print for the range on your configuration.
Key specs
- Type: 2-way LCD with security system, plus 1-way companion remote
- Features: keyless entry, starter interrupt, siren, temperature display, silent mode

4. Viper 4806V 2-Way LED: Best for Manual Transmissions
The 4806V gives you Viper’s two-way confirmation at a lower price by swapping the LCD for LED indicators, which also show cabin temperature. Viper rates it up to 1 mile and lists support for manual-transmission remote start, which many systems do not offer. The remote battery lasts roughly three to six months.
Key specs
- Type: 2-way LED
- Range: up to 1 mile (Viper rating)
- Features: LED start confirmation, temperature check on LEDs
- Supports manual-transmission remote start
- Install: professional, usually with a bypass module
👍 Pros

5. DroneMobile X1-MAX-LTE: Best Smartphone Control
DroneMobile turns a compatible Compustar (and some other Firstech-family) remote start into an app-controlled system that works anywhere you have cell service, with Bluetooth as a backup when there is no signal. It adds GPS tracking, impact and tilt alerts, geofencing and voice control through Alexa and Google Assistant. It needs a subscription, with GPS features on the higher tiers.
Key specs
- Type: LTE smartphone module with GPS and Bluetooth backup
- Range: wherever you have cell coverage
- Features: impact, glass-break and tilt sensors, geofencing, smartwatch and voice assistant support
- Requires a compatible remote start system; professional install
- Subscription plans start around $5 per month

6. Viper 4115V 1-Way: Best Budget Viper
The 4115V is a simple one-button starter for drivers who can see their car from the house. Viper rates it up to a quarter mile, and the parking lights flash to confirm a start. It is designed to work alongside your factory key fob for locking and unlocking, and it can be upgraded with Viper’s SmartStart module later.
Key specs
- Type: 1-way, one button
- Range: up to 1/4 mile (Viper rating)

7. Compustar CS930-S: Entry-Level with Keyless Entry
Compustar’s CS930-S is a one-way system rated at 1,500 feet that adds keyless entry to remote start. It is a good fit if you want Compustar’s dealer support and warranty without paying for two-way confirmation. As with all Compustar products, buy and install through an authorized dealer to keep the warranty.
Key specs
- Type: 1-way with keyless entry
- Range: up to 1,500 ft (Compustar rating)

8. Avital 4115L: Two Tiny Remotes on a Budget
Avital, a Directed brand like Viper, packages the 4115L with two micro-sized one-button remotes, so both drivers get one. It is rated to about a quarter mile, includes one auxiliary output and can be upgraded to phone control with a SmartStart module.
Key specs

- Range: about 1/4 mile

9. Compustar CS800-S: Cheapest for Older Cars
The CS800-S is a long-running, very affordable one-way system with two four-button remotes that also handle locking. Its listing rates it to 1,000 feet. On older vehicles without transponder keys, handy owners have installed it themselves; newer cars need a bypass module and real wiring skill. Note that Compustar does not warranty units sold through Amazon or other non-dealer channels.
Key specs
- Type: 1-way, two 4-button remotes
- Range: up to 1,000 ft (listing)
- Keyless entry; upgradeable to 2-way with an RF kit

How to choose a remote car starter
1-way, 2-way or app. A 1-way remote sends the start command but cannot tell you whether it worked, so it suits cars parked within sight. A 2-way remote beeps, flashes or shows an animation to confirm. App modules work anywhere with cell service but add a monthly fee.
Real-world range. Manufacturer ratings run from about a quarter mile for basic 1-way remotes to a mile or more for 2-way fobs. Buildings, parking garages and interference cut range significantly, so buy more than you think you need if you park at the office or an apartment lot.
Vehicle compatibility and bypass modules. Most modern cars have an immobilizer that blocks a keyless start. A vehicle-specific bypass or data module (iDatalink, XPRESSKIT or Fortin) and T-harness solve that, but they are often sold separately. Push-to-start and key-ignition cars use different hardware, so check your exact year, make and model first.
Professional vs DIY install. Crutchfield recommends professional installation for most people. Best Buy’s install service is listed at $149.99 for labor, with the bypass module often extra. Skilled DIYers with plug-in T-harnesses may manage, but some brands void their warranty without dealer installation.
Warranty facts. Under the Magnuson-Moss Warranty Act, an automaker cannot void your warranty just for adding an aftermarket part; it has to show the part or install caused the problem. Poor wiring can still lead to denied claims, which is another reason to use a reputable installer and keep your receipt.
Manual transmissions and subscriptions. Manual cars need a starter that specifically supports them, with safety steps to leave the car in neutral. If you want phone control, compare subscription tiers: basic remote start is the cheapest, while GPS tracking costs more.
FAQ
Does a remote starter void my car warranty?
Not automatically. The Magnuson-Moss Warranty Act means the automaker must show the aftermarket part caused the failure before denying coverage. Keep install paperwork and use an experienced installer.
How much does remote start installation cost?
Labor alone is often around $150 at big-box installers, plus a bypass module for most newer cars. Installed packages from dealers commonly run a few hundred dollars, depending on the system and vehicle.
Can I install a remote starter myself?
Possibly, especially on older cars or with plug-in T-harness kits, but it involves splicing into vehicle wiring and programming modules. Most experts recommend a professional for newer push-to-start vehicles, and some brands void their warranty on self-installed units.
Do remote car starters need a subscription?
Only app-based systems. Key-fob 1-way and 2-way systems have no monthly fees. Smartphone modules like DroneMobile and Viper SmartStart charge monthly or yearly after any free trial period.
