Sorry for your loss and have to say your experience of Police response mirrors my own
We keep our keys in a pouch inside a tin overnight. I did try taking the pouch we bought up to the car with the key in and it still unlocked though..... maybe a bit too cheap!
I don’t carry the pouch round all day - defeats the purpose of keyless entry. I also agree with the other person who says at least keeping them in a tin means they don’t lose the keys around the house!
A few weeks ago I came home in pouring rain and in the hurry to get the kids inside left the keys on the passenger seat. Wifey came home, saw the car was unlocked and locked it with her key. Interesting that it locked successfully - glad nobody came around that night.
I would also recommend cameras outside the house. We have three covering the driveway and can see everything. I catch the Amazon man leaving parcels on the doorstep and not even knocking!
