Random Unlocks

I searched the forum and found one other thread on this, but no solutions.

I have a 2018 TRD Sport. I noticed 2 nights ago that the truck unlocked 4 times in an hour (this was via a camera I have on the driveway). The truck does not re-lock, as it is supposed to if you don't open a door, the doors remain unlockes.

I notice it happened again yesterday and again this morning.

Also, when the doors unlock, it does not beep, but the lights flash.

My key fob is in the house when this happens. Also, when it does this, it unlocks all four doors.

The only recent nod I have done was a Meso Key Minimalist Key Fob, but I switched back to the original key fob to rule that out as a possible cause.

So, any ideas why this truck just decided to unlock itself randomly?

Any possible solutions?

I only have 6k miles, so I'm going to call the dealership on Monday.

Thanks in advance for any help.

 

Maybe it's picking up interference from something, if you are parked elsewhere does it do the same thing?

 

Good question. I haven't left the house since Wednesday. I'll check it out when I go back to work on Monday.

 

Hmmm door handle sensor maybe?

 

That would be my guess

 

This is interesting. There has been a hand full of times where I swore I locked my truck and it was unlocked when I came back to it. I have never witnessed it unlocking. It’s usually when I go into a store. I do have Meso’s fob but I noticed this before I had it.

 

Doesn't the door handle only unlock the driver's door? All four doors unlock in my situation. I do not have it setup for all doors to unlock.

 

You can set it to all 4. Mine does all 4.

Not sure. This is a conundrum.

 

I believe you can, but I do not have it set up that way.

 

I had a 2010 titan that did this. Turned out, water had gotten into the fob making weird connections. Might be worth a look inside your fob.

 

FOB's are dry. Plus, it's not automatically locking like it's supposed to if a door isn't opened.

 

Tried something a little different today. Manually locked it from the driver door, removed batteries from both FOBs and low and behold, all four doors unlocked within an hour. Know I'm super stumped. She's going to the dealer on Thursday. I'll report back with what they find, if anything.

 

Ever took the door panels off and unhooked the connectors?

 

No I have not.

 

Sounds like an RF interference thing. Near where I live, there is Cheyenne Mountain Air Force Post. A lot of residents would report garage doors opening/closing in the middle of the night, cars unlocking, and other things on RF transmit/receive devices. Do you have a military installation nearby (within 5 miles)? If they are doing certain tests, there can be happenings on devices that are within the same frequency range.
Does it only do that at home?
Shit, it could be random WiFi signals, with unintended harmonic interference due to poor shielding within that WiFi signal. You could find out who's WiFi router is throwing shit signals (possibly even your own?) and have them reconfigure their router.
Have you ever noticed on remote controls or wireless (land line) phones on the item itself it'll say "this device may not cause harmful interference, this item must accept any interference received"? That can happen on any RF device. It seems that your truck is within the frequency range of something else nearby. Maybe ask the dealer if they can reset or reprogram your key fobs...bring both to the dealership, btw.

 

So, I actually live near Flight Production Facility. But, I also work on said facility. The truck did not do it yesterday while at work, but as soon as I got home, within 2 hours it unlocked.

 

Maybe there is something from a neighbors house causing the interference.

 

Or maybe it's a high tech nerd neighbor that needs to better shield their hobby.

 

Another possibility is an active robbery threat.

 

Gamma rays. It's a real thing.
