Passive Keyless Entry based on Proximity

You deserve to have a convenicence to unlock your car before you touch a handle, walk away to lock it, turn your light as you approach. Or activating any other 10 electronic accessories based on your proximity. That’s why VAIS Technology developed the award-winning Smart Entry-Exit Recognition (SEER) system that equips virtually any model vehicle with sophisticated passive keyless entry kit based on proximity.

Why Use Proximity based Passive Entry?

So why not use SEER for your daily driver and add these modern conveniences with several key benefits, including: 1. VAIS Technology manufactures every component in the SEER system to OEM quality standards. The SEER module is housed in a sturdy metal housing. Cables and connectors are all OEM grade. 2. SEER is unlike other keyless entry kits. It’s expandable and customizable controlling from one to 10 separate electronic functions. The best part is that you can start with three or four functions and expand to others limited only by your own creativity. 3. Your vehicle is customized– so should your keyless entry and keyless start system. Utilizing the SEER Flow Editor allows you to select the specific sequence and timing of all operations controlled by SEER. For example, not only can you define the sequence of door unlock, flash parking lights, and light interior, but you can specify the time between each of these actions. Use your imagination. Your SEER system could potentially trigger anything electrically powered on your car, truck or SUV. 4. You might have read articles online about how thieves can hack into an OEM keyless entry system and steal a vehicle or its contents. That’s because many OEM systems are susceptible to Relay Attack or Remote Replay. The signal between your device and your car is captured and then used to unlock your vehicle without your knowledge or permission. A thief can then steal your possessions or drive away in your car, truck or SUV.  

SEER is a Passive Keyless Entry system with built-in proximity sensor. Above all it magically welcomes you back to your car each time by unlocking your doors and turning your lights ON. And similar when you leave, it beeps to signal doors are locked and lights are OFF. Giving you an absolute peace of mind knowing your car is always locked.

SEER uses Low Frequency (LF) technology to track your position. So when you approach ‘the zone’ it switches to high-speed Radio Frequency (RF) to measure each step with amazing accuracy. Therefore you can customize your system to trigger your lights and locks at different distances.

There’s also a security aspect with adding Passive Keyless Entry. So you want to make sure the car can only accessed by the owner. Today’s car thieves can capture the signal between your key fob and your car and use it to electronically unlock and start your vehicle when you’re not there. This is referred to as a Relay Attack or Remote Replay. A thief can then steal your possessions or drive away in your vehicle. This vulnerability is common in aftermarket or OEM systems. Our system provides protection beyond even the latest OEM systems by implementing advanced encryption technology to prevent Relay Attacks and Remote Replay. See our blog to learn why this Passive Keyless Entry System is so superior to Bluetooth or NFC keyless entry systems.

In conclusion after you try proximity keyless entry, you just can’t live without it!
