    Hey all... Have a 2017 Limited. Have converted both keyfobs (one meso, one AJT). Both worked fine, and now suddenly neither seems to "find" the key in my pocket when I approach and unlock the truck, or leave and lock the truck, from the handle.

    I have to sometimes put the key right next to the handle to get it to work. Same for push starting the car.

    thought maybe the battery, since it seemed to be happening to both, but swapped one out and didn't make a difference.

    Any ideas appreciated? thanks,.

    Truck cap , husky liners, deflector shield, ARE truck cap.
    Changing the battery in the remote would be the first step.

    Just curious, but what setting is your bed light switch set to? I've done some troubleshooting on mine with a similar issue and I have a theory.

    Not sure OP, but I'm having similar problem with the doors not locking using the key fob or touch pad on handle when interior lights are on. But when the interior lights time out, you can lock the doors with fob or by using the touch pad on handle as normal. Maybe a relay going bad in both situations :notsure:

    you know... now that you mention it, I just installed the Meso 3rd brake/bed light. checked that.. still set to auto.

    just tried @Tacoma1845 suggestion, and he may be on to something. seems to work fine once the interior lights go out.

    maybe I blew something installing the 3rd brake light.

    adding @MESO just in case he can think of a connection.

    I installed the ultimate maps, dome, turn signals, BD5 third brake light, and puddle lights.

    I have the domes and signals as well... but no problem then. Again, timing does seem suspicious now that I think about when I put the BD4 on.

    I sent Meso a PM to see if he'd chime in with thoughts.

    oh crap!!!

    I also have LED headlights, although I also did that year+ ago.

    maybe with the one additional mod (meso 3rd brake light), it sent it over the edge. I love these mods, but not as much as a working keyless entry.

    and there is no way I can take that 3rd brake light off.... ruined the original getting it on. Maybe the headlights back to the originals, or the domes.

    Damn. This bums me out.

    EDIT: I did turn the bed light to off, so it doesn't come on when you lock/unlock door. that seems to have fixed it... for now, but obviously not optimal.

    surprised other MESO groupies are not having this problem.

    Ah ha, so my theory applies to your truck as well. I started having issues with locking my door before I installed my Meso 3rd brake light. I thought it was the FOB, so I replaced the batteries in both FOBs but still had the issue. I tried a handful of things before I realized that it would lock perfectly as soon as the dome lights turned off. Eventually I discovered that turning the bed light switch to OFF would allow it to lock immediately again when using the smart handle or the FOB. I don't know exactly what's causing the issue unfortunately.

    are all your LED MESO lights? I had some off brand LED bulbs that I bought on Amazon and when I took them out, the door handle and keyfob buttons worked fine. Could be cheap Chinese LED's Try removing each one by one to find the culprit. If it is all MESO, he uses good quality LEDS, but you can check the same way to see which ones are causing the interference.

    BD. I was having the same issue before I added the BD lights though. I think it started happening not too long after I added a power tailgate lock.

    I have BD as well... and a power tailgate lock, but haven't added that yet.

    Hmm I also have remote start, Meso map and leds, Meso puddles, Winjet taillights, Diode Dynamics reverse leds and license plate leds. I'm probably forgetting something...
