I did a long drive today. Stopped once at some services, then again to pick up my father and drive him 1 mile to my brothers house. When I got there, parked up. My key stopped being recognised and I could not lock the car. No idea why not. Luckily, BlueLink did lock the car for me.

I went in and took the key apart. didn't seem to be anything wrong. Wiggled the battery - no, still didn't work. 3 hours later I went back out and it worked fine. And has continued to do so since.

The only thing I can think of is that someone had a powerful transmitter nearby and was transmitting.

Anyone else seen this?

Just checked. Both keys had batteries (Panasonic) with 3.02v. The replacements were 3.34v. So, I've swapped them out and I'll see what happens.

Just happened to me today. It wouldn’t let me lock the doors after I parked. Display read that key was not in vehicle. It was in my pocket. I started the car, let it run for a few seconds, and turned it off. Problem seemed to rectify itself. Guess this is what happens when we drive computers on wheels.

My Brother's BMW does that from time to time. Car always starts but it thinks the key is not there sometimes.

My door only locks via proximity every 1 in 5 times. After spending most of my evening reading here I also believe it is an issue and not just user error. (And even if it is user error, it is poor user experience. Shouldn't be that hard to lock a door.)

Are you swiping your hand across? Try that and not going for a particular spot. Works every time first time for me and my wife.

Well, I went back to the same place again - and again the key didn't work. I restarted it, moved it 100 yards down the road and it worked just fine. So, I think someone or something is transmitting some powerful radio waves.

I have different problems with operations of the vehicle when I have my fob with me. First thing in the morning, I walk up to the read of the Tucson, and it starts beeping about to open the hatch, later, when I walk up to the rear area..nothing, I have to use the fob to push the hatch open button. I also have problems with opening the doors, same issue, works fine, go into a grocery story, come out, nada, have to get out the fob and push button to unlock.

I've had two incidents - the first I was alone and there was no response from the key fob. I tried everything and then used Bluelink to start. After that, the fob worked perfectly. The second time I was with my partner, and both had fobs. When we stopped, my fob wouldn't lock the door, so we tried my partner's - that didn't work either. Neither would the finger lock on the handle. Again, I used Bluelink to unlock the car, and then our fobs worked.
This is a crazy situation - what if I didn't have Bluelink or my phone? Definitely something Hyundai needs to address, and I will report it at my next service.

I don't have a cellphone, believe it or not, may have to get one although I would hardly use it. My problem seems to be with most of the electronic devices installed on the vehicle. I've turned off the 'smart' tailgate, it used to work once first thing in the morning, never again until the next day, became a pain, gone. The door unlock doesn't seem to want to work in cold shady areas, don't ask, don't know why. It locks well. The flash drive works, use it for pre-recorded jazz I've downloaded onto it, so there's something, keeping my fingers crossed....

I've since found that there is one area near my brothers house where the fob just doesn't work. Move the car 20 yards further away and it's fine. Luckily, I can use Bluelink on my phone to lock and unlock the doors. I think there's some radio waves bouncing around nearby.
