As far as I know, the fob doesn't emit a signal unless a button is pressed. Retrace your steps. Check washer and dryer. Check pants hanging in the closet. Check behind toilet.

 

Got any electronic engineer friends with RF generation/detection equipment? If so, they may be able to broadcast a 125 kHz "wake up" signal while listening for the 315 MHz answerback signal from the remote.

This morning, I had a close call with my beloved Apple AirPods. I went to grab them on my way out the door and they weren't where I usually place them. I found them in the back pocket of yesterday's jeans which were staged for laundering. *PHEW*

 

Dont forget to look in the dirty laundry pile either. Garbage bins, kitchen counters, fireplace mantle, dining table, hutch, etc etc. These are the places my wife normally leaves her keys. Good luck.

 

If it was a "senior moment" I'd look in the refrigerator and freezer too! If you have a recliner and it fell out of your pocket they are like a Black Hole so flip that chair over. >

 

Had that happen to our 1998 accord.....best we could figure is it got knocked off the counter into the recycle garbage can
If you have any open boxes/cans near where you normally place your fob at home, check them before ditching them (found another one in there a few years ago as well.....I moved that can now...)

 

I know this doesn't help with your current predicament...

A year or two ago we put Tiles on our keys and other things. They use your phone and bluetooth to help you find lost things. The Sport and Style models have twice the range and a louder speaker. The biggest downside is the battery isn't replaceable or rechargeable.

I also recommend TILE, just last weekend my daughter lost her keys during a beach photo shoot and I was raking the sand in an attempt to locate it with no luck. Then we used the TILE to get a general location, then we listened for the audio sound when searched for her TILE with her phone. Even with the noise of 6 foot surf we were able to hear it. I came home and ordered 4 more PRO TILEs, so I would have them on all our keys. Just relocating one lost fob or phone and it pays for itself. Ours did just that.

I remember reading a member's post either here or on Piloteers.org that he cannot find their Pilot's fob which he remembered was on the counter. He asked his wife but she doesn't know where the fob is. He ended up took each trash bag out of trash bin to near their car and one bag opened door. The lost fob was inside the trash bag.

Also check inside Ridgeline around seat; around your shoe station.

 

The bag idea is a good one ! I'll have to remember it. At least you don't have to root through all the trash that way!

I have tried everything I can think of. I dragged every garbage bag, laundry hamper, pile of clothes, drawer in the house next to the door and nothing. I have even gone as far as taking the backs off all the couches to search the crevasses and taking the beds off their frames. At least my house will be super clean (Silver lining).

Still...there must be some technological solution. I'm not giving up. lol

 

Did you check the truck? This just happened to me last week. Was frantically looking everywhere and finally checked the truck. Senior moment? I'm only 45, lol

We have a half a$$ hidden key hanger, all keys go there. At night the car fobs are at bedside with the Glock, if someone breaks in i will set the alarm off on the vehicle and grab the Glock.
Hope the noise from the vehicle make them think twice.
I back tracked a half mile in the bush looking for a Quad key 2 years ago and found it, damn kids . That bright orange paint on it paid off, been doing it for years and it paid off.

 

If it comes to it, replacement key fobs are $57 each at Bernardiparts.com, although I think this is something I would buy from my local dealer in case there's any programming needed. Or, at the least, call your local dealer's parts store and ask them about that. There's probably a key number somewhere. Perhaps others will chime in with that information.

It appears the part numbers are:

72147-T6Z-A21 (driver 1)
72147-T6Z-A01

 

Don't forget the physical key that slides into the remote - it doesn't come with it. There's a metal stud with a hole in it on the remote that you could attach to your key ring, but the remote will look unfinshed and will have exposed. sharp plastic edges.

The key is part number 35118-T2A-A50 (about $30 at your local dealer or online + shipping).

 

I've had this happen with my Ridgeline fob. One Saturday they just up and disappeared. I checked every.single.place I would have put it. Then I searched those rooms. Then I went back and searched again. I played back my every moment since the last time I would have had the fob (as I remembered it, threw it on the kitchen table after picking up my daughter earlier that day).

I retraced my steps, inside and outside. I did an outside walk-around during the day, at dusk, and at night with a flashlight to see if I could get a "glint" off any metal. I searched the basement, where I had done some work earlier. Silver lining - the basement hasn't been this clean in a while.

I searched every logical living space in the house. Checked in our reclining couch more times than I can remember, upended it, shook it. Yes, I shook the effing couch as if the keys might fall out.

There comes a point in a keyhunter's existence when they have hit bottom, and I knew I was there when I started rooting through the trash. It started when I tried holding the trash bags up to the door when trying to open it. Also tried opening the door with the spare key, set the garbage on the passenger floor, moved the spare back inside, and tried to start the truck with the trash bags in it. No dice. From there I went to dumping it out on a tarp and sorting it back into the garbage bags. Vile. No keys.

It had less to do with the replacement cost than it did with the fact that one of the keys looped onto the fob was a nice custom key for my Dad's place, that and the fact that it was utterly insane that a set of keys could so completely disappear. It ruined an entire weekend just dwelling on the stupidity of the whole thing.

Couple days later, I'm still in that mode. Couldn't walk into a room without poking around at stuff, looking in drawers I'd already looked in a hundred times. Yet there were still places I hadn't ventured - the depths of the kids' rooms with their bins of toys and books and clothes, for example. The bathroom closet where no rational person would ever put a set of keys, but...

In the bathroom closet there are numerous baskets, into which bathroom stuff is organized. Band-aids. Vitamins. Extra toothbrushes. Miscellaneous girl's hair doodads - headbands, clips, barrettes ... BINGO. There they were, interwoven with a stack of plastic hairbands. I wouldn't have found them if I hadn't actually lifted the hairbands out of the basket to see the fob hanging off the bottom.

As the story goes, my wife had done my daughter's hair in the kitchen and just brought out the whole basket of hair crap to get the job done. Somehow the keys had gotten mixed up in the works and thereby disappeared into the depths of the bathroom closet. They were only found by virtue of having looked where I would have NEVER put them intentionally in a million billion years.

My wife lost her Odyssey fob back in January and still hasn't found it yet. I suppose there is a chance it snuck out in the trash, but she did the same trick with the trash so my bet it's still in the house somewhere. Mysteries of the universe.

 

I especially like the garbage-proximity Ridgeline-start-up attempt. That's classic!

 

^^^
So funny! This is exactly what I'm going through. I'm glad that I'm not the only one out there. There is still hope for me to find them yet.

 

I wish you all the best. It's a maddening exercise, for sure. Have you brought a stepladder into the center of each room and looked around like I did (for the sake of getting a different perspective?) Taken out all the floor vents and gone shoulder deep into your duct work? Cleared out the refrigerator to see if they got absentmindedly dropped behind the lunchmeats? It's impossible to not become a little insane when you're looking for lost keys.

Like I said we're still looking for my wife's fob. I suppose we've passed into the "Acceptance" stage on that one.

Carry on, seeker!

 

Best of luck. Do you have a dog or other indoor pets? Have you tried putting them near the vehicle? When my escape or "f" keys go missing. I just have to search anywhere my bird may have taken it...

 

This was one of the first things I tried. Grabbed the dog and picked him up beside the door...no luck.:crying:

 

Thinking about this a little bit more - going back to my multiple experiences losing Honda keyfobs my first thought is also that there must be some way to trigger the key with a phone app or something. The nature of how these things work requires that such a thing is theoretically possible, otherwise the proximity sensing wouldn't work (user pulls door handle - vehicle has to "ping" the keyfob, keyfob has to reply with a signal back to the vehicle or the door will not unlock).

I could be wrong on this but the keyfob probably contains something akin to an RFID chip that is not technically "powered" all the time, but includes a type of antenna that creates an electric current when it picks up a certain electromagnetic signal from a transmitter (in this case, the vehicle). This way the key is effectively woken up by the vehicle and doesn't have to stay powered on all the time which would quickly burn out the battery. There is no reason why someone who knows more than I do about RFID technology couldn't come up with some hack that would put out the same "proximity sensing" signal that the vehicle does, and detect the reply from the keyfob. But even then it would only work within the functional range of the proximity sensing feature, and it would be difficult (though not impossible) to make a device able to identify location to the signal. Assuming a cell phone could transmit / receive in whatever frequency is being used by the Honda key system, the best a phone app could do is a call / listen function and give a beep if a response from the key is detected. Then you could at least play "hot / cold" with your phone until you locate the fob by process of elimination.

My Dad is a ham radio operator with a background in EE, and tons of associated toys. If I get a chance I might ask to borrow his oscilloscope and see what notes the Ridgeline and fob use to sing to each other.

EDIT: So now that I'm thinking about it I google "what frequency do honda keyfobs use to communicate" and the mysteries of the universe begin to open up, and I don't suppose I should be surprised that it edges into the realm of black-hat hackers and car theives:

https://www.maximintegrated.com/en/app-notes/index.mvp/id/3395
https://www.wired.com/2014/08/wireless-car-hack/

Point being, I'm certain that there is a technical solution to the "fob finder" problem, whether or not it exists IRL yet is a different question.

 

^^^Makes sense. So which luxury carmaker will be the first to integrate a "Find fob" button on the original factory fobs? You take your second fob and simply move around the areas where you might have lost the first fob and push the "Find fob" button. When you get within say 20 ft of the lost fob, it will beep. Kinda like how how you could find a lost phone handset (remember those?) by pushing the "Find Handset" button. Some entertainment system remotes also have this feature.

 

Well, this is the first time I have ever "misplaced" car keys this bad, but my FOB is no where to be found, Just called the dealer and to order a new FOB, cut the emergency key, reprogram both FOBs will cost $184. We'll then also need a new tailgate key, but I should be able just to go to any key shop to have that done I am thinking?

That's relatively inexpensive.

 

When I bought my 2017 had a spare key and fob made. Cost around $150 then to order and have programmed. Went to dealer with only #1 fob, was told they neede both fobs. Service tech said he can do with only one fob present and he did. Several years ago wife lost her small purse looked all over. Two years later found it in the material where the foot rest on recliner folds out. Hope you find it.
