Word of warning to all Ioniq 5 owners. My new car was stolen off my drive, presumably with a cloned key. it is a mystery how they managed to clone the key as we keep it in the house well away from the car. Gone in 30 seconds!! We heard of another one being stolen a week later a few miles away.
I am shocked the manufactures still cannot provide sufficient security to stop this happening. There is more security on my iPhone. A simple pin number entered on the screen before the car will start would be sufficient .
The supplier has suggested I buy a steering lock and a faraday box for the replacement car, which I will, but a steering lock is a backward step which I had on cars 20 years ago.
if the car had proper security in the first place aftermarket security should not be necessary. Now I will need to keep looking over my shoulder when I open the car to make sure no one is near enough to clone the key!!

If I'm not mistaken, all modern cars with keyless entry/start are prone to this, not just Hyundai/Kia. I've seen it often on Channel 5 cop reality shows ... thieves use a device to send thousands of queries from your driveway seeking a response from your smart key (said response being to unlock/start) ... then they are away in seconds. Only solution seems to be to keep all such keys in Faraday pouch or bag (I've used a pouch for years on my normal use key and another on my spare key ... you can check their effectiveness by making sure that you cannot open your car (even when standing beside it) with the key in the pouch). Sorry to hear your tale of woe. Hopefully your insurance pays up immediately and you get a new car promptly.

There are three different attack approaches being used and all the EGMP based cars (Ioniq5/6, Kia EV6 and Genesis GV60) are currently susceptible to all three approaches.

Relay Attack
The common relay attack (which is widely publicised). One device takes the signal from your key fob amplifies it and send it to another close to your car. The car simply sees the correct expected signal and opens and starts.
This can me mitigated by keeping your keys in a container that does not allow wireless signals to leak out - a Faraday box.

Key Cloning
This approach requires access to your key to simply make a digital copy, which for all intents and purposes is then identical to the original.
Careful who you give your key to.

Key Emulator
A device is placed close to the car to receive the car's signal. The device then takes between 10 and 120 second approximately to find the correct signal to unlock the car and this can then be saved for later use.
A secondary authentication system is needed to prevent the car from starting, but if this is hooked into Bluelink that can be disabled once access to the car has been gained. There's not much apart form physical krooklock type approach that can help here.

Hi Stephen. Just came across it. It's a growing problem, Hyundai are aware of it but doing nothing. Have you seen this thread on Twitter?
We have a growing group of owners like us who lost our cars and got no support or answers from Hyundai. Can you join us? If you want, you can message me here or message the guy on that thread who coordinates it - Robert Whiteside
