I had a lock (£14.99) fitted into door (£30 labor) & NO key? It can be opened/locked with a screwdriver. I returned to B&Q for the key & they say it doesn't come with key but for £3 I can buy they key !
If you can open and lock it with a screwdriver then I think B&Q have lost the plot.
Local Burglars must be rubbing their hands with glee. Put a notice on the Door 'Open House' ! duh !
If it's the Front or Back Door of your House tambo I would change the lock completely even though it would involve more expense. It's too high a risk if you can open door with screwdriver..
Is this one of those security locks that fit top and bottom of the door and you insert a grooved key into the hole, on the inside only, and wind a round bar out into the jam?
If so, then I believe they do come without keys as you only need one key for however many locks you fit.
