What is the uniqueness of Evoque keys and key fobs?

Today, I experienced a slight shock. A woman knocked on my door, appearing contrite. My car, stationed on the roadway, was emitting a distressing sound as the alarm had been activated. She expressed her apologies and indicated her own Evoque situated 50 meters down the road, identical in colour and external aspect. She stated that she activated my alarm by unlocking my car with her physical key, entered the vehicle, but recognised her error when she was unable to start it. She had left a paper in my car and sought to recover it with my consent.

How distinctive are keys and key fobs? What measures are in place to prevent an individual having an Evoque key from attempting to access additional Evoques or Jaguars in the vicinity? Disabling the alarm is presumably simpler if one is inside a vehicle and possesses the requisite knowledge.

I am unable to address your inquiry; nevertheless, a similar incident occurred with my friend's BMW several years ago. While we were in a parking lot, he activated the unlock button as we neared his vehicle, and another BMW of the same model and colour responded by beeping and unlocking as well.
We drove a considerable distance, returned on foot to the other BMW to secure it, then walked back to his vehicle and departed.

seems really suspicious to me Why utilise the key when one possesses the fob, particularly considering that a female may wish to avoid soiling or damaging her nails? I trust you still possess your Evoque, my friend.

The fob was inoperative since it was not her vehicle. It was unexpected that the key functioned.

In the past, I inadvertently secured my keys inside on several occasions. The initial occurrence was, oddly, directly outside the Bromley police station. I entered with a sheepish demeanour and provided an explanation. The man at the desk enquired about the make of the car. Austin A60. He provided me with a set of keys, stating, "One of these will fit." The initial one succeeded. Individuals exhibited a high degree of trust throughout that period.
I applied this knowledge when I performed the same procedure on my Bedford CA, which is also an FS series key. Feeling embarrassed, I enquired of a gentleman parked along the road if he would assist me by unlocking my van. I believed his key would be compatible. Indeed, that occurred. Neither vehicle was particularly valuable, although the A60 was stolen on one occasion. Parked it in the centre of Regent Street, left the headlights on, and depleted the battery. They clearly did not consider it worth retaining.
