Probably a very dumb question here.....
We've got four exterior doors on our house. There's one where I'd like to have a double-cylinder deadbolt, but the others don't really need that.
Is it possible to use the same key on single and double cylinder locks, or do they use different types of keys? I was hoping to have the locks re-keyed so I could use one key for all doors. Otherwise I'll just have one key for three doors and a seperate one for the double cylinder locked door.
Thanks for any info!
