Key Fobs and LED interference

JbVt said:
I’ve had Lasfit cargo and 3rd brake leds in my 2020 ram since day one and don’t have any issues with the fob not detecting. Been in about 9 months now.

I had them for a few months on my 2020 Limited, no issues. Then one bulb dimmed, they sent me out a new bulb and thats when I started having key fob issues. Any time I unlocked the truck with the key fob and cargo light came on it would not detect the key fob to start until light went off. I got the 2021 Mopar LED light from a guy for 200 bucks on Facebook. he's sold a few to other guys as well. No issues now.

Ok guys your all missing a huge step.
First our trucks can come with LED lights. Their is programming that MUST BE ENABLED for things to not get stupid. Regular lights have voltage differences and LED forward voltage difference when not seen the BCM will go nuts. Get Alfa OBD and go to BCM go to the LED light section and enable CHMSL led present yes. Rather NO.
Your welcome.
If your in western mass, happy to help seeing I have the hardware

What version is better for alpha, Android or PC

Depends on your preference.

They are pretty much the same except one of them you can use your cell phone/tablet if it's Android.

I have an iPhone so I have the Windows version and use my laptop since that's my only option (I quit Android years ago). It's obviously more bulky to handle in/around the cab but I like the bigger screen. I also put my BCM list in a Word document so I can toggle back and forth between that and AlfaOBD as I'm changing things to make notes.

Anybody using 3rd brake LED from Lasfit? Does it interference with our FOB?

I have used the Lasfit versions for my 2019 RAM 1500 4x4 and it does have issues when I replaced my original 3rd brake light with the Lasfit LED version. Someone said something about having to use resisters with the LED bulbs is what the problem is. Some brands out there have resisters built within them that won't cause any problems like the Lasfit versions.
 
Just installed these on my 3rd truck in a row. Work perfectly, no issues, and very bright. Takes a few minutes to put in.

Have these continued to work for you with no key fob interference?
 
I seem to have the same issue with my cargo lights and FOB issue. So did Ram knowingly put inferior LED bulbs in for the cargo lights, otherwise how would this not get tested/picked up before truck was released.
 
These are aftermarket LEDs. The DT 1500 did not get LED cargo lights until 2022 MY.

2019-2021 trucks came with incandescent bulbs in the CHSML (cargo and brake lights).

I upgraded mine to some high quality units from Diode Dynamics after seeing great reviews on this forum. I now have Key Fob errors that are getting worse each day. So much for that idea...

Damn this has me worried now, I just upgraded my 3rd brake and cargo lights to the diode dynamics LED about a week ago, so far no problem, did you have the issue immediately or did it suddenly start happening after a while?
