1. The Evolution of Car Alarms: Why Aftermarket Still Matters
Factory car alarms often come with basic intrusion sensors and horn-based deterrence. Yet, a majority of thefts involve vehicles that rely solely on factory systems, which professional criminals can bypass in seconds. Modern aftermarket systems, like those by 1byone, add multiple layers of security:
- Multiple sensors (shock, tilt, ultrasonic, glass-break)
- Instant remote alerts or smartphone notifications
- Integration with GPS tracking and immobilization
- Panic modes, silent paging, and remote disabling
- Auxiliary controls like remote start, keyless entry, and trunk release
Upgrading to an aftermarket car alarm remains one of the best investments not only in your car but in your peace of mind.
2. Understanding 1byone Car Alarm Technology
1byone integrates several advanced yet user-friendly features across its alarm lineup:
- Wireless Sensors: Detection for vibration, tilting, door or window breach, plus “aux” zones for custom sensors.
- Remote Transmitters: One-way and two-way remotes allow arming, disarming, panic, valet modes, and even remote starting.
- Mobile Integration: Newer models support GSM modules or proprietary apps for alarms and vehicle status updates direct to your phone.
- Engine Immobilization: Prevents hot-wiring and unauthorized engine start even with key duplication.
- Customizable Sensitivity: Adjustable triggers mean fewer false alarms.
- Visual and Audible Warning: Sirens, flashing lights, and/or notifications.
- Compatibility: Most 1byone car alarms are made to fit a wide range of 12V vehicles—cars, SUVs, even some motorcycles.
3. Top 1byone Car Alarms in 2025: Detailed Reviews
1. 1byone High-Security Wireless Alarm Kit
Best For: Easy, Universal DIY Installations & Essential Protection
Key Features:
- Core wireless system: central module and remote key fobs
- Dual-stage shock sensor, tilt detector, auxiliary input for door or bonnet switches
- Panic mode, car-finder, valet mode
- 110dB siren, visible dashboard LED
- Remote range: up to 500m (open)
- “Plug and Play” wiring harness
Performance & Review:
This is 1byone’s flagship “classic” alarm kit, popular with DIYers and older car owners. Installation takes under two hours with basic car wiring knowledge. Dual-stage shock sensitivity picks up both light bumps and heavier attempts at forced entry. Panic mode is easy to activate (double-tap on the remote) and the system remembers settings after power loss. Auxiliary sensor port makes the system expandable to perimeter, glass-break, or even trailer sensors.
Pros:
- Affordable and beginner-friendly
- Great range and false-alarm protection
- Compatible with a wide variety of vehicles
Cons:
- No remote start or mobile app
- Manual arming/disarming
2. 1byone Smart Keyless Entry Alarm System
Best For: Modern Keyless Entry and Security in Older Cars
Key Features:
- Central locking/unlocking with included remote key fobs
- Shock/tilt/glass-break detection
- Ignition starter cut-off relay (immobilizer)
- Universal fit for cars with existing central locking
- Loud multi-tone siren, visual LED flash
Performance & Review:
A great upgrade for vehicles lacking keyless entry: this kit adds “click to unlock/lock” plus robust intrusion protection. The immobilizer relay prevents the engine from being started even if the original key is compromised. Alarm system “learns” your car’s locking pattern, so you can arm/disarm and unlock the car with a single button press.
Pros:
- Seamlessly combines security with modern comfort
- Immobilizer is effective against both theft and key cloning
- Wide vehicle compatibility
- Sensitivity easy to dial in
Cons:
- No 2-way feedback (remote doesn’t signal back)
- Smartphone control not supported
3. 1byone 2-Way LCD Remote Car Alarm
Best For: Real-Time Monitoring & Two-Way Paging
Key Features:
- Two-way LCD remote (receives status notifications, not just sends commands)
- Smart spectrum hopping to reduce interference
- Up to 800m range
- Battery backup for alarm module
- Engine immobilizer relay
- Sensors: vibration, tilt, glass, door
Performance & Review:
For tech-minded drivers or those in theft-prone areas, the two-way paging and LCD display are invaluable. The remote vibrates/beeps and displays intrusion status instantly. You’ll know if a door was opened, glass broken, or an attempt to start the car occurs, even from afar. Customizable zones allow different levels of sensitivity—less false triggering when parked on busy streets.
Pros:
- Pro-grade, serious security
- LCD/remote acts like a silent pager
- Easy-to-read real-time alerts
- Works in almost any vehicle
- Long battery life in remote
Cons:
- Slight learning curve for advanced features
- Price is higher than single-way alarm kits
4. 1byone GSM GPS Car Alarm (with App Integration)
Best For: Smartphone Control, Live Tracking, & Fleet Security
Key Features:
- GSM module (SIM card required) for real-time app alerts
- GPS tracking: live location, travel history, and geofencing
- Remote arming/disarming by phone, SMS, or call
- Cut-off engine function via phone command
- Vehicle battery tamper alert, backup battery for alarm
- Sensors: shock, door, perimeter
Performance & Review:
This is 1byone’s most advanced system, combining alarm/immobilizer with live GPS tracking. Installers recommend this for business vehicles, delivery vans, and any cars parked in theft hotspots. You can create a geofence—if your car leaves a preset area, you get a push notification. Phone-based arm/disarm is reliable, and the backup battery means the system still functions even if the main car battery is disconnected by thieves.
Pros:
- Remote app control puts full power in your hands
- GPS lets you always know vehicle’s location
- Ideal for both personal and small business/fleet use
- Can remotely cut off engine if you detect theft
Cons:
- SIM card and data plan needed for GPS/app features
- App setup has a learning curve
- Installation best done by professionals
5. 1byone Standard Universal Car Alarm Kit
Best For: Wide Compatibility & Simplicity
Key Features:
- Entry-level single-way remote
- Sensitivity adjustment knob
- Door, bonnet, and shock sensor triggers
- Visual status indicator, 105dB siren
- Universal, easy-to-hide compact module
Performance & Review:
If all you want is tried-and-true protection for a daily driver, the Standard Universal Kit delivers precisely what you’d expect. It has the basics: intrusion sensor, loud alarm, visible warning, anti-hotwire lockout. The remote is tactile and long-range, with big buttons that are easy to use by feel.
Pros:
- Super affordable
- Simple, reliable, no app issues
- Perfect for older or secondary vehicles
Cons:
- No remote start or fancy feedback
- Not as advanced as pricier models
6. 1byone Car Immobilizer & Engine Cutoff Alarm
Best For: Highest Anti-Theft Security
Key Features:
- Standalone immobilizer relay module
- Pairs with any existing 1byone or third-party alarm
- Two “hidden” remote fobs (RFID proximity-based)
- Will not allow start unless fob is present
- Anti-tamper and physical relay lock
- Ideal for luxury and collector vehicles
Performance & Review:
This is an ultra-reliable “second layer” alarm for high-value vehicles or areas with organized theft risk. No matter how a thief gains physical access, without the unique paired fob present the engine won’t start. System is invisible to thieves and resists even advanced hotwiring. Owners report it stops “relay attacks” that some new cars experience.
Pros:
- Ultimate peace of mind
- Unhackable engine lockout for most cars
- Works with factory keys or as add-on to other alarms
Cons:
- Doesn’t notify user if car physically entered (paired with other alarm recommended)
- Installation into ignition system is complex, best for pros

5. Key Features to Look For in a 1byone Car Alarm
a. Sensor Suite
Look for dual-stage shock, tilt (for towing/jacking attempts), glass-break, and door triggers. More is usually better for layered security.
b. Remote Range and Feedback
Longer-range remotes are useful for larger parking lots. Two-way or LCD pagers notify you of an alarm event.
c. Immobilizer Circuit
Engine immobilizer is a must-have for full theft prevention.
d. App/Smartphone Integration
If you want mobile notifications or GPS tracking, ensure GSM or Bluetooth support.
e. User-Friendly Arming/Disarming
Big, tactile buttons; clear LED indicators; silent/valet options.
f. Audible and Visible Warnings
Sirens of 100dB+ and blinking dash LEDs deter casual thieves before attempting entry.
g. Reliability/Warranty
A one- or two-year manufacturer’s warranty is standard; ensure your vendor honors it!
6. Installation: Professional vs. DIY
DIY-Friendly Kits
1byone’s basic alarm kits and keyless entry systems are designed for home installation. If you’re comfortable with car electronics:
- Use supplied harnesses and follow clear color-coded diagrams.
- Remember to disconnect your car battery during install for safety.
- Test all features before finalizing the wiring.
When to Go Pro
Models that require GPS, smartphone/GSM features, engine immobilizer (especially those integrating with new cars’ anti-theft BUS systems), or connecting multiple sensors are best installed by a certified professional. This ensures validity of your warranty, proper engine cut-off relay placement, and no drawn-out troubleshooting sessions.
7. Real-World Performance & User Feedback
Thousands of customer and technician reviews praise 1byone for:
- Reliability: Most users see years of operation with minimal hiccups.
- Customizability: Level of sensor/sensitivity adjustment means less frustration with false alarms.
- Value: Features rivaling systems several times their price, especially for keyless entry plus alarm in a single kit.
Most common user complaints involve false alarms caused by over-sensitive shock detection (which is easily tuned down) and, rarely, interference in apartment or urban complexes with lots of radio noise.
