Compustar 2WQ9R-FM Q9 2-Way LCD Replacement Remote Transmitter

Up to 3,000 Feet of Range

Compustar officially rates the Q9 for up to 3,000 feet of maximum range under ideal conditions.

That is roughly half a mile.

Real-world range depends on factors such as:

• Buildings
• Concrete walls
• RF interference
• Antenna placement
• Terrain
• Parking structures
• Vehicle location

The 3,000-foot figure is therefore a maximum rating, not a guarantee that the signal will travel through every building between you and the vehicle.

Still, it is substantially more range than a factory key fob and gives the Q9 plenty of reach for:

• Large parking lots
• Apartment complexes
• Office buildings
• Shopping centers
• Long driveways
• Multi-story parking areas

FMX Communication With 128-Bit Encryption

The Q9 communicates using Compustar’s FMX RF technology with 128-bit encryption.

The purpose is to provide reliable long-range communication while helping protect commands from unauthorized interception.

Compustar also uses frequency-hopping technology across most of its modern remote platforms to make RF communication more difficult to capture and replay.

For a replacement remote controlling security and remote-start functions, encrypted communication matters.

You’re not just changing radio stations.

You’re sending commands capable of unlocking and starting a vehicle.

Five-Button Control Layout

The current 2WQ9R-FM uses five buttons.

The large front button can handle several commonly used functions depending on how it is pressed.

Compustar documents operation such as:

• Tap to lock
• Double-tap to unlock
• Hold to remote start
• Hold while running to shut down remote start

Additional side buttons provide access to other supported system functions.

That keeps the remote relatively compact without sacrificing control.

Remote Start Control

When paired with a compatible Compustar remote-start system, the Q9 can start and stop the engine remotely.

That makes it useful for warming or cooling the vehicle before you get in.

Remote start can allow the climate-control system to begin:

• Heating the cabin
• Cooling the cabin
• Defrosting glass

before departure.

If you’re upgrading an older vehicle or learning how remote start integrates with factory electronics, our guide on how to convert a car to remote start explains the control module, bypass, immobilizer and safety systems that make remote starting possible.

Lock and Unlock

The Q9 can also control compatible power door locks through the installed Compustar system.

Its large central button makes the most frequently used commands straightforward:

Tap → Lock

Double tap → Unlock

The remote can then provide 2-way confirmation that the system received the command.

Alarm Notifications

When the Q9 is paired with a compatible Compustar security system, it can also receive supported alarm notifications while within RF range.

That may include alerts generated by:

• Door intrusion
• Shock sensors
• Tilt sensors
• Hood triggers
• Trunk triggers
• Other connected security inputs

This is particularly useful because a siren only helps if someone nearby hears it.

A 2-way remote can tell you that something happened.

Replaceable AAA Battery

Unlike many premium remotes that use an internal rechargeable battery, the Q9 uses a standard AAA battery.

Compustar estimates battery life at up to 63 days, although actual life depends on usage and environmental conditions.

There are some real advantages to this approach.

When the battery gets low:

1. Replace the AAA battery.
2. Keep using the remote.

No charging cable required.

For a replacement remote that may live in a glove box or serve as a backup transmitter, replaceable batteries can actually be more convenient than rechargeable ones.

Up to 63 Days of Estimated Battery Life

Compustar rates the Q9 at up to 63 days of estimated battery life.

Actual battery life can vary based on:

• Number of commands sent
• Alarm notifications received
• Temperature
• Display usage
• Battery quality
• RF communication conditions

Still, standard AAA power makes replacement quick and inexpensive.

Q9 vs. T12

Both the Q9 and T12 are premium Compustar 2-way LCD remotes, but they target different price and range levels.

Compustar Q9

• Up to 3,000-foot range
• Full-color LCD
• AAA battery
• Approximately 63-day estimated battery life
• FMX 128-bit encrypted communication
• More affordable premium LCD option

Compustar T12

• Up to 3-mile range
• 2-way LCD
• IPX-7 waterproof
• Rechargeable lithium-ion battery
• Premium long-range platform

For most normal parking situations, the Q9’s 3,000-foot range is already substantial.

The T12 makes more sense when maximum RF range and waterproof construction are priorities.

Q9 vs. T11

The older T11 sits in Compustar’s premium 3-mile LCD category.

The Q9 offers less maximum RF range but provides a full-color LCD interface at a more accessible level.

Q9

• 3,000-foot maximum advertised range
• Full-color LCD
• Replaceable AAA battery

T11

• Up to 3-mile advertised range
• LCD interface
• Rechargeable battery
• Higher-end long-range platform

The Q9 is ideal for buyers who want strong range and 2-way LCD confirmation without needing Compustar’s extreme-range platform.

Replacement Remote, Not a Complete System

This deserves emphasis.

The 2WQ9R-FM is the remote transmitter itself.

It does not include everything required to add remote start to a vehicle that currently has no Compustar system.

If you’re starting from scratch, you typically need a compatible:

• Compustar control module
• RF antenna
• Remote-start wiring
• Vehicle-specific interface or bypass
• Safety inputs
• Security hardware if desired

The Q9 is best for replacing or adding a remote to an existing compatible installation.

Compatible Antenna

Compustar currently specifies the:

ANT-2WFMX

as the compatible antenna for the 2WQ9R-FM.

This is critical.

Compustar remotes operate on specific RF platforms.

A remote that looks similar does not automatically work with whatever antenna is already on the windshield.

Before ordering, verify the antenna model.

Compatible Compustar Control Modules

Compustar currently lists the Q9 as compatible with control modules including:

• CM-900X
• CM-DC3
• CM-X
• CM2305-A
• CM2500
• CM7000-AS
• CM7200-S
• CM900-AS
• CM900-S
• CMBMXA0
• CMVWXA0
• SmartKey Starter for Mercedes-Benz

Compatibility can depend on the complete installed system, firmware, antenna and configuration.

The safest way to order a replacement remote is to identify both the control module and RF antenna already installed in the vehicle.

Why the Antenna Matters

The remote doesn’t communicate directly with the vehicle’s factory electronics.

It communicates with the Compustar RF antenna.

The antenna then communicates with the Compustar control module.

So the communication chain looks like:

Q9 Remote

↓

ANT-2WFMX Antenna

↓

Compustar Control Module

↓

Vehicle

If the antenna operates on a different Compustar RF platform, the Q9 may not communicate with it.

Can You Program the Q9 Yourself?

Compustar systems support remote-pairing procedures, but the exact programming sequence can vary by control module and installation.

Do not assume every installation uses an identical pairing process.

Before programming the replacement remote:

1. Confirm the Compustar control-module model.
2. Confirm the antenna model.
3. Verify Q9 compatibility.
4. Follow the correct Compustar remote-programming procedure.

If the system isn’t entering programming mode, don’t immediately assume the new remote is defective.

The issue may involve the antenna, control module, valet/programming switch or system configuration.

Does the Q9 Need a Dealer to Work?

The remote does not normally require the same kind of vehicle-specific immobilizer programming that a bypass module does.

However, it still has to be paired with the compatible Compustar system.

If you’re uncertain about the installed controller or antenna, a Compustar installer can identify the system and confirm compatibility.

Does the Q9 Include DroneMobile?

No.

The standalone 2WQ9R-FM replacement remote should not be confused with the RFX-2WQ9-FM bundle.

2WQ9R-FM

The Q9 replacement remote itself.

RF-2WQ9-FM

Q9 RF remote kit with compatible antenna hardware.

RFX-2WQ9-FM

Q9 remote package bundled with DroneMobile LTE connectivity.

Those are three related but different products.

Does the Q9 Have GPS?

No.

The Q9 remote communicates over RF.

It does not contain a GPS vehicle-tracking system.

If GPS tracking and smartphone control are desired, a compatible DroneMobile LTE/GPS module can be added to supported Compustar systems.

Does the Q9 Require a Subscription?

No subscription is required simply to use the Q9’s traditional RF communication with a compatible Compustar system.

Subscriptions apply to optional connected DroneMobile cellular services, not normal Q9 remote operation.

Great Replacement for a Lost or Damaged Compustar Remote

The Q9 is especially useful when:

• Your original Compustar remote is lost
• The display is damaged
• You bought a used vehicle with a Compustar system but no working remote
• You want an additional transmitter
• You want to move from a basic compatible remote to LCD feedback
• You need a backup for another driver

Before ordering, identify the installed RF antenna and control module.

That five-minute check can save you from buying a remote that looks perfect but speaks a completely different RF language.

A replacement for a lost remote

A replacement for a damaged LCD remote

A second remote for another driver

A 2-way LCD upgrade from a simpler compatible transmitter

Strong range without stepping up to the 3-mile T12 platform

For everyday remote-start use, 3,000 feet is a lot of range.

More importantly, the Q9 tells you whether your command actually worked.

Because pressing remote start from the sixth floor is much less useful when you’re still wondering if the car heard you.
