Remote out of control

I refer to your front page article (Car Crime Call, News, 24 July).
One simple reason for this is that remote key locks do not have a unique signal frequency for each and every car.
Ten years ago while holidaying in Perth, my wife and I parked our hire car at a shopping centre.
Upon returning, I beeped the remote, we sat in, then realised we were in somebody else’s car, with their belongings in there!
We stepped out, spotted our own hire car, and tried the remote, only to discover that our remote made both cars lock and unlock!
Had we sat in the correct car the first time, then we would have not even noticed we had unlocked another car.
There must be hundreds of similar instances where people do lock their car but five minutes later the car is inadvertently unlocked by someone else parked nearby whose remote coincidentally has the same frequency.
So when Det Sgt Geoff Rumble says “I fail to understand how people don’t get the message” – I am sure that in many instances it is actually the car’s central locking that is “getting the message” – from the wrong remote!
