Question for Toronto Bloggers

One more thing - when you kids moved into your place, I assume you changed your lock or had it rekeyed? Does anyone have a recommendation on how to do that? The handle on our door is pretty nice in that it matches the mail slot and age of the house so I'm not super keen on changing it with any old lock set from HD.

I've heard we can either re-key it ourselves (??) or have a locksmith come. Any recommendations/referrals?
