Passive and Remote Keyless Entry
Technology
SEER combines two well-known technologies to track your movement with precision. It detects you with Low Frequency (LF) signals when you’re approaching a vehicle, or a specific “zone.” Once you have been detected, the system switches to high-speed Radio Frequency (RF), accurately measuring each step you take. This pinpoint accuracy lets you effortlessly trigger locks, lights, or other features exactly when you want, giving your system a level of precision and convenience that feels almost magical.
Security
Adding Passive Keyless Entry also enhances your vehicle’s security by ensuring only the owner can access it. However modern car thieves can intercept the signal between your key fob and car, using it to unlock and start your vehicle without your knowledge—an attack known as a Relay Attack or Remote Replay. This makes your car and belongings, expensive tools, packages, and other cargo very vulnerable, It’s a known weakness found in both aftermarket and OEM systems. Our system goes further, offering protection beyond even the latest OEM solutions with advanced encryption that blocks Relay Attacks and Remote Replay. Check out our blog to see why our Passive Keyless Entry system outperforms Bluetooth or NFC keyless systems.
Once you experience the convenience and security of proximity keyless entry, you’ll wonder how you ever lived without it!
