good to knowChanged the battery in my keyfob since it died in me yesterday and left the truck sitting at a gas station at 6:30 in the morning. Luckily I had my daughter following me in her card so was able to make it to Ice Cream Cruise on time for work. Then had my wife and step son come and deliver the truck to me using her keyfob. I was under the impression we could still start the truck, even with a dead battery, because the RFID chip didn't require power. But nope.
True storyI also love working on my truck….

Did not work. Tried multiple times with pushing the start/stop button with remote. Each time it displayed "fob not recognized" on dash. Granted, this is an aftermarket fob.This didn't work?
My fob battery seems to be on its way out as well and I had an episode of an unresponsive truck a few nights ago. Their demo worked for me without an issue.
So I think I figured it out. I have the AJT keyfob cover. There is a small piece in factory fob that I didn't transfer over because I didn't know what it was. I tried my completely gutted factory fob, that only had that piece left in it and it started the truck. Now to try and get that piece out to put in the AJT fob.This didn't work?

Confirmed. Once I got that piece out, which required hacking up the factory fob because it's glued in, I could start the truck with just that little chip and pushing the start button with it. The AJT install instructions do not mention this rfid chip at all, yet they have a spot for it in the fob case. View attachment 168023View attachment 168024
That is the security chip. That is the part that has to be programmed to the vehicle. That chip is what makes it unique. Back in the days of key start, I buried a chip in my dash, so I could use cheap non chip keys in one of my cars.Confirmed.

The fob, with the rolling codes, gets programmed to the truck. Which is why I have been able to use my AJT case with zero issues until the battery died. This is just basically a "back up" RFID chip that has to be in close proximity to the receiver in the dash. Hence having to push the start/stop button with it. The regular fob, when battery is good talks to the truck in a different wayThat is the security chip. That is the part that has to be programmed to the vehicle. That chip is what makes it unique.

I'm just glad the circumstances lined up to where I wasn't left stranded waiting on rescue, and that the truck was only 20 minutes from my house, so wasn't too much to have my wife go pick up the truck and bring it to meSorry this happen to you. But glad it did. I need to check my fob. I don’t remember transferring that chip.
I thought you just switched cases. I would have thought it wouldn't work at all, to start, without that chip.The fob, with the rolling codes, gets programmed to the truck.

It does, which is how people are claiming fobs to steal trucks.I thought you just switched cases. I would have thought it wouldn't work at all, to start, without that chip.
How long did your keyfob battery last? How many times per week do you use it, and how many years did it last?Changed the battery in my keyfob since it died in me yesterday
