Key FOB issues

[Runaround]

I have a 2014 Tradesman with the three button FOB. Occasionally I can get in the truck and try to start it and nothing happens, the gauges don’t move, the starter doesn’t engage, nothing, sometimes it won’t engage the starter but I get a message saying wrong key FOB and other times the truck works as normal. This is the FOB that came with the truck but theFOB battery has been replaced.
When it doesn’t do anything or I get the message I can try several times and then it will work and other times I have to remove the FOB and put it back in the ignition switch and all works well.
What could be causing this?

Do you know where the TIMP is in the engine bay?

It is text to the battery on the driver-side it is part of the fuse box.

You’re the second person from Texas ( in two days ) to have this same problem.

Yes I know where the TIPM is on my truck
What does knowing where it is do for me?
Maybe it’s the Texas weather. Ha ha.

You said the fob battery has been changed but make sure the battery is still good. If you have the second fob try using it instead of the one you've been using.

TIPM: Check all fuses, make sure all seated. After that, could be a RF Hub issue. I have also heard this issue allegedly being related to a win module (ignition) issue also. You need to search threads, there are more than a few on how to troubleshoot the particular issue. All IMHO only.

Wont recognize key. Truck won’t start

I’m thinking for some reason the truck is not liking the key this morning. Most of the time it does not even acknowledge the key is being put in. Just yesterday were looking at the information on the display in the truck it said I was running at my normal voltage. What is going on? I have the...

look for green slime or oxidation on the contact points of your fuses and relays

Ok, I disconnect the battery for around twenty minutes, touched the cables together for a little while and checked the TIPM and things looked good there.
Got back in the truck, tried to start but it wouldn’t start even after several tries. Took the FOB out, reinserted it still nothing until I took it out and turned it over. I have better luck with it starting with the FOB buttons facing the passenger side of the truck, but sometimes it still takes several tries before it will start.
I noticed the door chime would sound off just before I turned the key and the truck started. I had the door open, but it never chimed on the attempts to start when it wouldn’t start.

Update. It was a bad key FOB. I finally got the other FOB, put it in and everything works great, no problems.

I have a 2018 Ram 2500 Turbo Diesel. Lately my truck beeps for no reason, like someone is pressing the lock/unlock button on the key fob. I have a Tip-Start Key fob. Has anyone else encountered this problem? I did replace the batteries in the key fobs. I don't know if that resolved the issue though. Thanks for your reply.

Check the contacts on the inside of the keypad, common for them to come loose and randomly activate the FOB
