key fob issue

Good Saturday morning

I own a 2017 MKC Black label.
We bought it used this last December with around 8k on it.
Nice car.
My wife is the primary driver.
We live in Wisconsin where it can (as is currently) pretty darned cold.

The symptom 1:
My wife tells me that she can't always rely on her key fob for starting the MKC.
She tells me sometimes it works and sometimes it doesn't.
Sometime she is inside our house (about a 75 feet from the unattached garage) with the garage door opened and it works fine. But sometimes it doesn't.
Ans sometime she is maybe 20 feet away from the MKC, inside a building where she works, behinds a clear glass window, and it doesn't work. But sometimes it does.

Symptom 2:
I keep the second MKC fob (it came with 2 of them.) inside my car which is parked next to the MKC in our garage.
This morning I went to start the MKC with my fob and I received a notification in the dash display reading "no key was detected".
And the fib wouldn't do anything else either.
So, I went back in the house and got my wife's fob and things worked fine.
I started when I got in the MKC.

So then, I left my fob in the house while I took the MKC to fill up with gas. (It's about the only time I get to drive it.)
When I returned (about 30 minutes later), I tried my fob again and it worked perfectly.

It was exactly 1 week since I last used my MKC fob.
Last Saturday in fact when I filled it with gas.
It's been pretty cold as of late with below zero wind chills.
But, my car and my MKC fob are in an unheated garage most of the time.

Questions:
Anyone else experienced something similar ?

Think the issue might be fob battery related ?

Any ideas as to what the life expectancy of a 2017 MKC fob battery might be ?

Is the battery something I might change myself or it a dealership thing ?

recommendations as to what I might want to do next would be greatly welcomed.


As an aside.
Neither my car (2012 Equinox), nor the car we traded in for the MKC(2010 Lacrosse) ever had such an issue in all years we have had them.


Thanks for any and all replies

I found two of the answers I was looking for.
The fob battery should last for at least 5 years.
And yes, the battery is something that anyone can do.

When my fob battery was low I got a warning message on the dash. Replaced batteries and all was fine.

. Battery is very easy to replace and you can get them at most pharmacies. My dad's f150 ( same key) battery went bad at just over a year, and I constantly replaced batteries in my Passat with keyless system (twice in the three years I owed it). A little hint, if the battery (in the key) is dead there is a hole in the front side of the center console that the key will slide into and then the car will start, at least you will not feel stranded.

If you don't first mess up you will never learn.

I hadn't thought of that.
Thanks.

Thanks for the encouragement.
I'll pick up some replacements later this morning.
Certainly can't hurt to put a new one in.

And thanks for the hint about that hole.

I believe I looked for that hole when I first got the vehicle and couldn't find it.
But I do need a proper pair of glasses. (One of my 2019 resolutions.)

I'll look again with a better flashlight and maybe just feel around a bit to see if I can locate it.

Thanks for your reply

I had my MKC for about 3.5 years before I got the message on the screen that the battery in the FOB needed to be replaced. Changing the actual battery is easy but getting the FOB apart to do it is no easy task.

The hole in the centre console is at the bottom forward side of the compartment. I just feel around with my hand to find it.

Good evening. The "no key detection" happened to me this morning for the 1st time. I have had my 2015 MKC for 14 months and this is the 1st time this happened. I hadn't driven my car for 3 days & it is garaged the whole time. I never lock it when it is in the garage. I replaced the fob batteries 12 months ago after getting the message "key battery low replace soon". I tried the second fob unsuccessfully to start the car then decided to replace batteries in both fobs. When I went out to the garage to try to start the car again the door was locked and I couldn't open the door with the manual key (I may have been doing something wrong). I took apart the fobs again ( not easy) & reset the batteries & took both fobs to the garage... the door unlocked & I could start the car! I now carry BOTH fobs with me because I don't want to get stranded anywhere.
Where is the hole in the console to start the car with the manual key? I can't find it!. is it near the USB ports, SD slot? Thanks!

The hole for the fob is in the centre console (lift up the console cover). It is on the front side of the console near the bottom.

PS.... It is NOT in the small compartment in front of the cup holders where the 2 USB and SD slot is located
