How Do I Know What Frequency My Key Fob Is: Decoding Wireless Secrets

“What is the frequency of my key fob transmitter? Key fob transmitters are an integral part of remote keyless entry systems, comprising a transmitter (key fob) and a receiver within the vehicle. In the United States and Japan, the prevailing frequency for these systems is 315MHz. Meanwhile, in Europe, the standard frequency is 433.92MHz, but to meet the increasing demand for remote keyless entry systems, Europe has additionally allocated the 868MHz band for this purpose.”

How to Locate Your Key Fob Signal

To locate your key fob signal, you’ll need a key tracking device or a mobile app that’s synchronized with your key fob. This tracking setup comprises two essential components: a remote and a receiver. To initiate the tracking process, employ the receiver to transmit a signal, which can then be traced using either radio frequency technology or Bluetooth connectivity.

If you opt for a Bluetooth-enabled key finder, you’ll need to establish a connection between the finder and your smartphone for tracking purposes. This connection allows your phone to receive and interpret the Bluetooth signal emitted by your key fob, facilitating efficient tracking and ensuring you never lose sight of your keys again.

“How can I determine the correct key fob to order for my vehicle? To identify the right key fob, start by checking the numbers located on the back of your current key fob. These numbers should match the ones listed on the replacement fob you’re considering. If you don’t have a working remote to compare with, you can contact your local dealership for assistance. Simply reach out to their service department and inquire about your key fob part number. Be sure to have your vehicle’s VIN (Vehicle Identification Number) on hand, as they will likely request it to provide you with accurate information. This ensures you get the correct key fob for your vehicle.”
