Did You Know? . . . Proximity Keyless Entry Remotes

Did you know that there are many different types of proximity remote transmitters used on car and truck factory keyless entry systems? Remotes Unlimited refers to all of them as proximity remotes. Sometimes we refer to them by other commonly used names, such as “Smart Keys” or “Fobiks”.

Proximity remotes have several different possible features. What is universal in these parts is that they all have some form of transponder that is activated when the keyfob is close to or inside the vehicle. When the keyfob with its active transponder is present, a system in the vehicle is then available for use or automatically put into operation. What that system is depends on the vehicle and, conceptually, is only limited by the imagination of the vehicle design engineers.

For instance, many vehicles, such as Volkswagen, include a proximity feature that enables a person with the keyfob to enter the vehicle without having to press an unlock button on the remote. When the keyfob is near the vehicle, any slight pressure on the door handle unlocks the vehicle.

Other vehicles with seat memory systems automatically adjust seats based on which keyfob is proximate to the driver-side door when the vehicle is unlocked.

The most common feature of a proximity remote, though, is to enable push-button (“keyless”) ignition.

One can imagine other features that might be triggered by proximity of a keyless entry system keyfob, such as activating heat or AC when the vehicle is cold or hot, respectively; or activating window defrosters under certain climatic conditions. Surely, these and other features are on the way. We may even be close to the day when your vehicle will automatically give you a stock report, weather forecast and recent results of your favorite sports teams without prompting as soon as you enter your vehicle.
