I’m always worrying whether i’ve locked the car using the remote electronic key crap. Â I’ve had to walk back many times to the car after parking to check if I’ve remembered to lock it. Â I was thinking why not have an indicator on the key itself which says whether the car is locked or not. Â Well I’m pretty sure someone’s thought of this earlier, but why don’t we have something like that ? I badly need a key like that for in fact anything that needs to be locked. The constant worrying about whether I’ve locked something is starting to annoy the crap out of me. Â How fucking hard can it be, lock and key industry ?
