Key Fob

[Mikedc1144]

2021 Ram Big Horn: On trip neither key fob would open doors. Used key to get in.
Once in, started truck-all normal!!
No problem since!!
Any ideas???

Maybe the batteries in the fob are bad.

RF problems? Unit not working, synched with FOB>? Hmmmmmm.

IF all OK now, taking to Dealer U will get the ole: Cannot duplicate. Hopefully, just a glitch and/or maybe some type of interference blocked FOB.

I have no advice, just a bit of information

If you Ram has the Keyless entry, Enter and Go
Not only does it have the ignition switch, it also has an RF HUB behind the rear seat on the drivers side

Sounds like batteries. Let the dealer sort it out under your warranty.

I started a thread on this exact issue a little while back! https://www.ramforum.com/threads/interesting-fob-issue.180652/

Did you recently replace any bulbs with LED's? That can cause issues like this.

Because of LED lights at a 7/11
My doors would not unlock

On my instrument cluster, i saw a message read out
I could not read it, but it was likely something like
FOB not recognized

after that, i always parked further away from the front door of the building

Lots of stuff nowadays that will interfere with the signal, including having your cell phone near your fob.
