You’ve once again misplaced your automobile keys. You’re certain they’re in your home, but despite looking under the refrigerator and between the cushions of your couch, you were unable to locate them. You have a keyless remote that appears to be in communication with your automobile, and you are wondering if there is any way to make it speak with you and let you know where it is. “Theoretically, it is feasible, according to electrical engineering and computer science doctoral candidate Phillip Nadeau, “but it depends on the kind of remote-entry system we’re talking about. Even then, it can be difficult based on the manufacturer and technologies employed.”

Remote Keyless Entry (RKE) and Passive Keyless Entry (PKE), the two primary categories of keyless remotes, operate in various ways. Only when you push a button on the remote control do RKE devices send a radio signal to your car. Nadeau says that “these gadgets are often solely outfitted with a transmitter.” Unfortunately, this prevents you from calling the remote. It can’t hear you any more than a skeleton key can.

Your chances are improved if you have a PKE remote. You don’t need to press buttons with PKE devices to lock or unlock your automobile. According to Nadeau, “the car transmits a signal that simultaneously powers the remote and requests a legitimate authentication code to open the car.” Similar technology is used by RFID card scanners to grant you entrance to a building without requiring you to take your ID card out of your pocket. A PKE remote, in contrast to an RKE device, includes both a transmitter and a receiver, allowing it to hear you call it using specialized radio equipment while you’re just acting like your automobile! Theoretically, you could create a special gadget that doubles as a radio transmitter and receiver, retransmitting the signal from your car and waiting for a response from your keys. However, if you have the technological know-how to build such a device, it should work. This is not a simple or cheap option.

According to Nadeau, as long as you have a lot of free time. “To elicit a response, the interrogator must be a short distance from the distant.” Most of the time, this proximity restriction is helpful since if PKE remotes had a long range, someone might steal your automobile while the keys are safely inside your home! However, it also means that in order to locate your keys, you will need to search every inch of your home with your tools. You might as well go back and rummage through that junk drawer one more time rather than spending the time and money developing some fancy radio equipment in order to find your keys.
