We live in an apartment complex that has a remote controlled lift gate access for the garage. I've been having issues with the gate not opening when I use the remote so I replaced the battery. The little LED on the remote is brighter but only works marginally better. On several occasions I actually have to be standing next to the gate receiver to activate it. Most other times I am less than 10ft away and it takes several seconds of holding the button before the gate lifts. I've observed several other residents activate the gate from across the street so I don't think it's the gate or receiver.

So I asked the building super to check it out. He blew out the inside of the remote with some canned air. We walked over to the gate and it worked fine. Then last night we come home and I can't get the gate to go up again and my wife has to lean out her window to get the remote closer to the receiver.

So this morning I'm walking the dog and with remote in hand I have no problem lifting the gate from any reasonable distance away.

So either I'm the nut job at this complex or I'm thinking my Santa Fe is generating some kind of jamming signal that prevents the remote from working well in the car.

I can't just buy my own replacement remote because it needs a special device to program it and the super isn't jumping to get me a new one.

I'm trying to think of ways to troubleshoot it. Maybe park at the gate with motor running or not and seeing if that has an affect?

Anyone else experienced this?

You could try swapping your remote with a neighbor / a known good device to see if the problem follows the vehicle or the remote. Aside from that you're asking how to troubleshoot and / or reduce RF interference which is a much more elaborate discussion.

Your suv is a faraday cage.
I have seen MIT MSEE that's gets stumped on EMI/EMC problems.

LOL...it just goes to show that Hyundai use better quality steel than all your neighbours cars are made from.

As above yeah. Experiment with different modes your car is in nad device off inside to see what allows it to work inside.

Engine off is of course the final mode. if that doesn't work then the signal is not strong enough or antenna used at the garage is poorly placed.

Someone once told me that the heater's electric blower fan causes interference, so try pressing the "off" button your on car's heat\AC unit just before you get home to open the gate and then see if that makes any difference.

Good luck!

Agree with Trip: Stop the engine and make sure the ignition is off, then try it. Don't forget that any tint film on the windows has a microscopic metal film in its laminate that will attenuate a signal that is already weak, so run the window down to see if that affects it.

Unfortunately there is no satisfying resolution to this one. I didn't borrow a neighbor's remote but did try as many combinations with car on/off, Bluetooth on/off, heaters on/off, etc. Nothing. The remote worked the whole time. That night I come home and dang thing doesn't work unless I'm right next to the receiver. Then the whole weekend and ever since the remote is fine.

Is your car one of those with the remote control buttons on the mirror? If so, you should be able to program your mirror buttons to match your gate transmitter. We don't know what year or trim line (GLS, Limited) your car is.

I totally forgot about those buttons! At our last house I always parked outside the garage (which was my woodshop) and never used the remotes.

I have a 2010 Limited. I installed one of those overwrap mirrors a few years ago--with the integrated front and rear cameras--so those buttons are covered now.

I am curious enough to remove the auxiliary mirror and try to program the buttons, however, there are 2 caveats. 1) I don't have direct access to the gate opener controls--there are 2 separate gates going into the building controlled by one button on the remote (pressed at different intervals) and a second remote button is pressed to open one gate leaving the building, and 2) we live overseas now so I'm not dealing with some US opener like Chamberlain or Sears.

This building was constructed in 1996 so I would assume the openers are about that age and might be using rolling codes. From this article, it seems like I might need direct access to the openers to press a button. Anyway, I'm going to flip through my manual and just give it a try.

The rear view mirror HomeLink feature would not accept the code from my remote control so I guess I'm just stuck with this remote. I must have given it a few proper whacks because it has been behaving since last weekend. Knock on wood.

Maybe you remotes battery connections are poor or flakey. If you did not get it new then replace the batteries in it. A lot of such devices use a cheap 2032 or 2016 (90% of FOB's use 2016). If other people don't have the problem then forget the vehicle and fix the power source in the unit.
