2 Rc cars being controlled by the same controller? Answered

So first off I don't know much about Rc cars so Ive looked online for a solution but can't find one, maybe I'm getting the wording wrong. I've just came across these forums so maybe someone can help.

OK so my nephew got a pair of Cars 3 RC cars for his birthday. They were working fine for about a day but now one of the controllers controls both cars at the same time and the other does nothing. I can't find any controls or switches on either car or remote except for the on/off switched. My question is, why is this happening and is there anything I can do to fix it? Also they both say they're 2.4ghz if that makes any difference

Thanks in advance

Found via Google searching... its a "pairing" issue.

The car works great as long as
you make sure you kid doesn't touch the center button (horn) on the
remote. If you do the car wants to re pair with the remote and you have
to turn it off and start over.

They are the first 2 results here. The Jackson Storm and Lightning McQueen ones.
They aren't the same as the controllers with these don't have horn buttons.

Did you try the obvious already?
I mean removing all batteries, wait a bit and then put them back?
Of course not all at once but one car /remote at a time and if working, turn them off again and insert batteries into the next one.
If that does not work look for a small pinhole on the tranmitter or car - usually there is a reset button somewhere.

As the stuck cycle rider who called the tow truck to pull his dirt bike out of the playa mud..

When the tow guy arrived to find the rider sitting waiting on a rock by a nearby road..

One look and the tow guy asked "Are you sure you want me to pull you out ?"

to which the rider said Yes !

Again tow guy asked "Are you sure you want me to pull you out ?"

to which the rider said Of course Yes !

O.K. the tow guy said "Sign here" and after the rider signed, the tow guy walked out to the dirt bike, lifted each wheel out and over and rolled the cycle out to the road...

The caller said "isn't $800 a bit stiff ?" to which the tow guy said "NO... I drove 2Hrs to get here and also included a Stupid Tax"

That happens more often then you might think.

2.4ghz is just the frequency range of the transmitter & receiver.

Remove the battery and using a resistor ground the transmitter long enough to discharge the capacitors, do this on both transmitters and receivers.

They are not the best transmitters and receivers you can get so cross over is common if you use both at the same time.

Let me say the same thing a bit more generally.

Modern RC is a "system" a transmitter and a receiver. To make it work the receiver is paired with the transmitter (like using bluetooth)

Looks like both cars cars are paired with the same transmitter. Check the web site or manual.
