How to Change the Frequency on an Invisible Fence Collar

Do you feel like you’re getting interference or false signals on your dog’s invisible fence collar? Wondering how to change the frequency on an invisible fence collar?

If so this article can help. We’ll cover the how to along with the legalities of doing this.

Super Basic Instructions on Changing Frequencies

Note – These instructions are for informational purposes only. They are basic and will only work for some receiver collars.

Changing frequencies may take you out of the bands legally allowed by the Federal Communications Commission (i.e. changing frequencies can be illegal if done incorrectly or sometimes if done at all). For funsies we’ll discuss these regulations in depth later below.

  1. Take off the back panel of your invisible fence collar and remove the battery if possible
  2. Take off the back panel of the remote and/or transmitter (some units come with both a walkie-talkie looking transmitter plus a remote button).
  3. Search the back panels for any option to change the frequency. In the old days there were actual analog dials that you could move up and down to change the frequency. For current models you’ll likely need a special device to digitially change the frequencies.
  4. If the receiver collar and transmitter have a way to change the frequency simply change them to a new code and make sure they match.
  5. Put the batteries back and replace the back covers.
  6. Test the units.

This is an overly simplistic approach that will not work for most receivers.

Instead you’ll need a manufacturer’s or distributors tool demonstrated in the video below.

Now on to the fun legal stuff!

Is it Legal to Change My Collar and Transmitter’s Frequency?

Yes and no. If you stick to the few basic channels allowed for these devices then you should be OK. The problem comes when you stretch out into a band or use more power than the FCC regulations allow.

The goal of the FCC is to basically get everyone to play fairly with a limited set of options in the electromagnetic spectrum.

For remote controlled devices like electronic collars that don’t transmit audio, that band is super small. Shock collars and transmitters operate on four bands – 26.995, 27.045, 27.095, 27.145, or 27.195 MHz.

If you change from one of those bands to another you should be fine. Of course, to be super safe you should consult a professional who understands the FCC regulations that control these devices.

If you feel like you’re having interference it’s likely not from similar device with similar signals. More commonly it’s from large, dense pieces of metal interfering with the signal, low batteries, or old devices.

Test the easy stuff first before messing with the frequencies.
