In normal use, like not throwing the key in the car after I've locked it, it won't let me lock the car with the keys in. It just does nothing when you touch the Kessy button with keys inside. That's occurred when I've forgotten to remove the key and try to lock it, to pay for fuel etc. It's those instances where this fails that people lock themselves out where it's misreading the presence of the key in the car.
Also if you have two keys. The Arona here can be awkward about opening the car with a different key to the one that locked it. This is where it's being packed to go away and we are using two different keys. There was one moment of trepidation once but the other key opened it. I might have locked key 1 in the car with key 2 out e.g.. mine. Recall it's what happended acquisitions flew but the second key opened it. The car was suppose to be left open and I locked it. Key 1 might have been out of the car when I did that but it was deemed my fault
... but once key 2 was used to open it or lock it all was good. Was an interaction of swapping keys in the open / close operation when the car was "live".
Throwing the key in the car after you locked it and doesn't open is probably down to the logic that the internal aerial gets turned off once you lock it to save power so it stops reading the key. May be what happended in the paragraph above.
The last conversation I had on the subject was where someone routinely kept their keys in the car and found themselves locked out later. I questioned whether they had used Obdeleven auto walk off and lock. That one, I wouldn't trust that. They never replied on that question.
I find it best not to test it to the limits since you don't want to get locked out. If you do get locked out, it's not working properly.
