For all those whos key gobs stop working. Worked on my 2014... Follow these steps.
Unlock doors manually.
Turn ON hazards.
Hold the lock on the fob for 5 sec.
Now put the key fob into ignition and turn to ON position.
Click unlock on the fob that's in the ignition. You should hear it unlock!!
Turn vehicle off and turn hazards off(unless you want to drain your battery.)

This works because usually while cleaning the vehicle while running, you trip a safety mechanism that disabled the fob with out you knowing.

Cheerz!!

One of my 2014 Laramie key fobs stopped working a couple months ago and assuming it was a dead battery I started using the other one, then today that one stopped working. I replaced both the batteries but no reaction from any button on either one. I ran across this post and thought it was worth a try. I followed the procedure, and although clicking the unlock button of the fob in the ignition while in the On position did not unlock the door as in the post, when I was done the fob worked again. I repeated the procedure with the other one and it now also works! Thanks so much for the post.

This was my issue a broken point on the battery clip. A little soldering later and she works fine.

For those of you having problems with your key fob not locking/unlocking correctly, You need to be aware that a marginal or defective tire pressure sensor can cause this issue by jamming your key fob signal. The key fobs use 315 Mhz as do the tire pressure sensors when activated. Mine also jammed my Ford Edge and my garage door remote, all of which uses the 315Mhz band. I have purchased a Linear model FT-1 Field tester. which detects the 315 Mhz band. It screams when this frequency is detected and can tell which device is transmitting. This has happened to me twice. Hope this helps.
Also a good tire store or your Dodge dealer can detect this.

Did this procedure work for anyone? This is the only forum anywhere I found this information.

If you read this whole thread multiple people said it worked for them.

Did you solve your issue with the push start. I have the same, although I'm not with my truck right now to try it.

 

[VictoryLapMB]

Ive never tried it with my ram yet. With other push to start vehicles ive had, if its not working hold it at the push to start button and then try start it up.

 

[jpHemi3]

Maybe I can **** of AustinB, hahaaha My Fob started today not working, I have changed the battery and clean contacts, this was working the other day. Any more ideas on how to fix mine? I also checked the doors and + you would still see your lights after pressing the buttons on fob

If the procedure in the previous page of this thread doesnt work for you,
You can get 2 new fobs for $18 shipped on ebay and program them yourself using alpha obd with an obd bluetooth adapter... the software and adapter are useful for multiple things from checking and clearing codes to enabling led lights or changing tire sizes as well. I programmed 2 ebay keys in august for my truck and they work fine. theres a you tube tutorial on how.

The following is a post I made previously in effort to get this issues corrected. The curiosity is that all FOBs failed in the same way, at the same time. Non of the common corrective action recommendations have worked. It is NOT batteries in the truck or the FOBs. I am still looking for reasonable suggestions. The truck is in the same driveway where I have parked it for years without issue so it is not likely an environment issue.

I will give the recommendation of andrewelmer1234 above and see if that gets me anything.


My 2015 Ram 2500 6.7 Turbo diesel has been awesome. With about 120k miles on it, I returned home from a short 30 mile trip into town. Shut the truck down got out and attempted to lock the doors with my key fob as usual. The doors did not lock. Tried all of the function buttons. No Panic, No lock/unlock and no remote start. Stick the fob into the ignition and the truck starts right up and runs fine. Repeat to process noted above with same result. Try my other three key fobs. Same result with two out of three and one fob just totally dead to include not starting the truck. (new battery in the dead fob changes nothing). Trouble shooting so far nets zero obvious leads. I have several tried several OBDII readers and AlfaOBD as well. I am at a loss. Any feedback or suggestions appreciated.

2021 RAM 1500 both FOBs stopped working simultaneously. Disconnected the engine battery, waiting a couple of minutes, connected it back, and they both worked. There definitely something in the truck itself that caused this issue so if it happens again, off to the dealership I go for some warranty work. Thanks!

I had an issue on my fob, it would not lock the doors but would do everything else. as it is a 2014 I've been in the fob before to change the batteries when I opened it up this time the switch plate was dirty and I used some contact cleaner with a cotton swab to clean the inside and the switch pads, it works again. youtube videos can show you how to get in the fob without damaging it.. Good Luck!

I will just bump this up to 2023...lol My 2014 just suddenly stopped working, all fobs. Used the method described earlier after messing with unhooking the battery etc. Worked like a charm. Only the fob that was in the truck is working, but I have one working!

This is the first reply in several hundred that I've read about the fobs that describes my issue.

Thank you... I had a feeling they were related because when the TPMS went on the blink so did the key fob response.

Now....to repair the TPMS.
