Step up to designer styles and superior security with Kwikset Signature Series products. The 980 deadbolt is both tough and attractive. The crisp, clean appearance of the Satin Nickel finish adds to the overall look of the product and brings a modern feel. This double cylinder deadbolt is operated by a key on both sides. SmartKey Re-key Technology allows you to control who has access to your home. Re-key the lock yourself in seconds in 3 easy steps. Have you recently moved or had a child lose a key. It's time to re-key. SmartKey provides the highest level of residential security and features BumpGuard to protect against lock bumping.
Bought this product about two years ago and have had no problems with its' operation. Recently had a break-in (not through this rear door) and was able to use the rekey feature to secure all doors with the same key. Recommend the double cylinder lock so burglers cannot kick in a door panel and reach inside to unlock the door by hand (happened to my front door). Will purchase another double cylinder for this door.
