My car (with keyless entry system) was broken into last night

Anyone remember when companies would send out promotional stuff through the post and you'd receive a 'Gold' car key, tempting you to enter the compo and thus maybe win the car to go with it?

The company had to stop doing this when someone discovered the key that was sent out in its thousands opened every MKIV Corrina.

I thought you could use anything to open a Cortina!
