Key not working in specific locations

[Trisonics63]

Maybe an odd one, but I’ve noticed in 2 places local to me, one being my doctors surgery and the other being my local Morrisons that my key will not work.

I get out and it refuses to lock, I can lock with my phone but key will not work and sometimes when I try to drive off from there it tells me the smart key isn’t detected.

Bit X-Files-ish but could there be something in the area causing this.

Is this to do with their internet servers?

Both locations will have an Induction Loop (for hearing aids), which can interfere with a keyfob signal, but as long as you're more than a couple of yards away, or in the car park, it shouldn't be a problem.
