I took my 2020 Elantra (key without immobilizer) in for the anti-theft software update. I was under the impression that this update would make it so that you cannot start the car when it is locked via the key FOB.

I did a test by locking the car with the FOB while sitting inside. Low and behold, it starts right up with the key (without unlocking the car with FOB). Has anyone else tested this new software update? Either i'm mistaken about what the update does, or the dealer simply slapped a sticker on my window without actually updating anything.

I was wondering about that since I thought only the push button start vehicles would need it, which mine is not. Since it's a big deal to even get to the dealership, I might try to get answers before bothering. Of course, the scheduler isn't going to be able to answer tech questions. I'm searching for someone else who might be able to explain it. Thanks for posting.

I read the details of the update and I won't be getting it. I had to pay additional for a third party remote start at the dealership when I bought the car. The tech info state that after the update the car can no longer be started without a key in the ignition. First, there is no way I'm going to leave the key in the ignition when I park the car. Second, I mostly use remote start in the winter. So if I got the update I would then have to go out to the car, clear the ice and snow, get in the car and put the key in the ignition, so I can go back inside and remote start the car? That's just absurd, not to mention less safe than what I have now. Plus NY state law prohibits that you leave a car running with a key in the ignition without the driver present. You can remote start the car and let that run, since the remote start 1) doesn't require the key and 2) automatically locks the car when it starts.

I too had questions after the update because I only got one key fob when I purchased a used 2019 Elantra. In reading the description of how the update would effect cranking the vehicle, I felt I would need another key fob for myself. (My wife uses the one that got when we purchased the vehicle.) The dealer wanted about $350.00 for a fob and programming!! When I got home I thought I would test the update. I got out of the car and locked it with the fob. Waited several minutes, unlocked the car with my key and it cranked. Repeated several times with same result. Nothing had changed! It made me wonder if the update was done so I contacted Hyundai Corporate to voice my displeasure with the cost of another fob and to find out if, based on my tests and the written description of what the update would do, was my vehicle working correctly. Corporate could provide no further description of what the update would do nor if my vehicle was functioning properly. In addition they sent me back to the dealer on the fob. I really wasn't surprised at Corporate since they had been mute on the "theft issue" for over a year. A total waste of time contacting them. I bought a fob from Amazon for less than $20 and I just need to get it programmed.

It will be interesting to see if any vehicles are stolen that have the "update"! I do think it is a little Micky Mouse that you have to lock the car with the fob to activate the updated theft feature.

My suggestion worth considering is installing a Compustar (but that's not the only brand) security system for probably a similar cost as what the stealership is asking (with a starter kill and your choice of fobs - might be able to retain the factory one as well.)

We have seen updated vehicle's stolen - most notably this one which was stolen six days after the guy got the update and posted a video testing it out. Of course we can't know the exact factors that aligned to his Elantra being stolen but he's not the only one.

I consider the update more smoke than substance since there's clearly some bypass or common condition - and also that it's little more than a band-aid/PR attempt. I got the system installed on my Kia a few days before the news of the update dropped and was a little salty at the timing but seeing how it seems to perform, I might still be ahead despite install costs.

I have tried to figure this out 8 ways to Sunday. All the update did was make my Hyundai acc. remote start beep twice after the car starts.
The car has a factory alarm that only sets with the remote and makes a horn honk is the door is opened from the inside. I think we are being conned to make sure we set the factory alarm.
Funny thing is there was more talk on the news about the recall and I just got an email from Hyundai about it.

My locked 2017 Hyundai elantra - updated with the same software and stickers added in March - was stolen yesterday. The back window was broken into and ignition ripped out to use the same USB trick to start my car without the key. THE ANTI-THEFT SOFTWARE UPDATE DOES NOT WORK. I am working through Hyundai customer service, who told me to work it out with my local police. Even though they claim to have fixed the theft issue. I am contacting attorneys for starting a new class action lawsuit on this supposed solution.

After reading all the posts of car stolen after upgrade I was concerned it was not worth it. I had it done. The Service advisor did show me how it works. You must lock the door with FOB until you hear the horn beep. For me, that is two times pressing the lock button on FOB. Service advisor showed me it was working properly when locked properly until horn beeps. He said the starter would be disabled when armed. Crossing fingers.

I did not remove my neon green bike cable with lock wrapped around the cover for ignition. Service advisor said any visual deterrent is good to have.

I think I'm going to get a push-button thing from a salvage yard and install it, and some kind of dummy cover for the keyn (just so my car would probably be bypassed, and thought of as a push-button start). I wonder how mine wasn't stolen yet, all the times it was in a crime-infested area with all those crime-prone people... smh... I guess the usual gang of idiot hoodlums don't want to steal a manual transmission car, lol :cool:.

Hello, I have a 2017 Elantra SE with key, had the anti theft software put on by Hyundai, my car was stolen last night at my house in Lancaster, CA. So it does not work. My neigbor almost got his car stolen, they broke the window, door handle and the inside, but he has a after market alarm so they left and he was able to move the car to the gargage for then to not steal it.
