Types of Keyless Start Kits
A keyless start kit is an electronic ignition system that replaces the traditional mechanical ignition switch. With this system, a driver does not need to physically interact with the ignition switch to start or stop the vehicle. As long as the key fob is inside the car, the driver can start and stop the engine with a push of a button. This system enhances security, convenience, and vehicle design flexibility.
Passive Keyless Entry Systems
These systems automatically detect the key fob when it's within a certain range (typically 1-5 feet) of the vehicle. When detection occurs, the system unlocks the doors and enables other functions:
- No physical button pressing required on the key fob
- Automatic door unlocking when approaching with the fob
- Some systems include automatic trunk access
- Enhanced convenience as the fob can remain in pocket or bag
Best for: Users prioritizing convenience and hands-free operation
Active Keyless Entry Systems
These systems require user interaction by pressing a button on the key fob to unlock or access the vehicle:
- Commonly used in trucks and vehicles with manual door locks
- Can be programmed to unlock only the driver's door initially
- Provides more control over the unlocking process
- Better security through deliberate activation
Best for: Vehicles requiring extra security measures and controlled access
Expert Tip: When choosing between passive and active systems, consider your daily routine. If you often approach your vehicle with hands full (shopping, children, etc.), a passive system offers significant convenience. For maximum security in high-risk areas, an active system gives you more control over entry points.
| Feature | Passive Systems | Active Systems |
|---|---|---|
| User Interaction | Minimal (proximity-based) | Required (button press) |
| Range | 1-5 feet typically | Up to 30-50 feet |
| Security Level | Good | Very Good |
| Convenience | Excellent | Good |
| Battery Life | Shorter (constant signal monitoring) | Longer (only active when pressed) |

Frequently Asked Questions
What is the difference between a keyless start and a keyless entry?
Keyless entry allows access to the car without using a traditional key. The system either responds to a button press on the fob or automatically detects the fob's proximity to unlock doors. Keyless start (or push-button start) specifically refers to the engine ignition system that allows starting the vehicle without inserting a key into an ignition switch. Most modern systems combine both features, but they serve distinct functions - one for access and one for engine operation.
Is keyless start as secure as traditional keys?
A properly installed keyless start system offers comparable security to traditional keys, with some potential advantages and disadvantages. Modern systems use encrypted signals between the fob and vehicle to prevent unauthorized access. However, sophisticated criminals have developed "relay attack" methods that can amplify and relay signals from key fobs inside homes to unlock and start vehicles. To enhance security, consider:
- Using a signal-blocking pouch for your key fob when not in use
- Installing additional physical security measures like steering wheel locks
- Choosing systems with advanced encryption and anti-theft features
- Parking in secure, well-lit areas whenever possible
