It may be easy, it may not - I have never done it before. The fact that there are so many locksmiths in business (and yes, probably the majority to open up locks people forgot keys to) leads ME to believe that it may not be the most simplest job in the world. I have 2 young kids, we are moving an entire house, and my time is money- some things are worth paying for if it saves you time and aggravation. I do not want to work on rekeying 10 locks in the midst of a move. If anyone has a recommendation for a locksmith that services Washington, I would really appreciate it.
