Residential & Commercial Security - Locks, Keys & Dead Bolts - Changing the key instead of the locks?

My home has Titan locks which can be locked and unlocked by the same key. Is there anyway for me to just replace the key instead of all the locks in the home? I don't have any information about the locks except I found a control key given to me by the previous owner. What is the control is for? Thanks for you help.

The control key allows the locksmith to remove the barrel from the cylinder. The control key has a slot in it that bypasses the spring loaded retainer inside the cylinder.

Titan deadbolts are very cheap (not the cheapest, but close) locks and the quality varies a lot.

Most legitimate locksmiths will not sell the product as it is very poor quality. It is primarily sold by hardware stores (a.k.a - untrained, unknowing barbs).

Re-keying the locks will be significantly cheaper than replacing, unless you decide to again install el cheapo products.

Thanks for the information.
