We've used the Schlage Camelot BE365 keypad deadbolt lock for about six years now, and have been pleased with the product. To replace your existing deadbolt, you'll only need a Philips-Head screwdriver. It's fine to leave the strike plate from a previous lock as long as it is still in good condition, but change out the deadbolt itself as well as the interior and exterior latch components. Schlage offers a 3 year warranty on electronics and a lifetime warranty on the mechanical components.
