Any hardware store should be able to rekey the new lock for you. They will either use the code stamped on the key, or measure it to determine the depth for each pin.
Kwikset and Schlage do have user rekeyable products as well (smartkey and securekey, respectively)
I have to replace a deadbolt lock, and I want to keep it keyed the same as the knob. Is this something that I have to get a locksmith to do, or is there a way I can do it?
Like others have mentioned, if your door knob is a Kwikset, buy the SmartKey deadbolt. Super simple to change keys. 1)Insert original key, 2)turn it a quarter turn, 3)push in a pin, 4)pull out original key, 5)insert NEW key, or in your case, the doorknob key, 6)rotate key and remove. All done in about 10 seconds. You can re-key as often as you like!
