Car Key Works On Neighbors Car Too

Occurred on March 16, 2020 / Northamptonshire, England

Info from Licensor: "I came home this afternoon and realized my van key unlocked my neighbour's car and locked it and set the alarm . Her car is a 64 plate fiesta and my van is a 58 plate transit . Strange? I leave before her everyday and she says her car has been unlocked every morning and both her buttons on keys have packed up."
