With Passive Keyless Entry (PKE), you no longer need to dig through your pockets or bag for your keys.

This feature is especially helpful when your hands are full with groceries, luggage, or children, offering a true hands-free experience.

The kit also provides Remote Keyless Entry (RKE) functionality, giving you the ability to lock and unlock your vehicle with the press of a button on the included fob. The remote works from a long distance, letting you secure your vehicle before you even reach it. Depending on your car’s wiring and compatibility, this system can add functions such as trunk release or a panic alarm can be enabled for added convenience and safety.

This system comes with unbeatable encrypted security communication. The communication between the key fob and your vehicle is encrypted to prevent hacking or signal cloning.

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!
