Touch If you have ever been locked out then you would appcriate Lockwoods keyless entry pin and card lock. The Lockwood 001 touch will go in place of an existing 001 deadlock. A few modifications and an extra hole are required but it is not difficult to change over.
Great for the kids coming home from school so they can't lose keys.
Also built in are a few features such as time limited codes for tradesman etc.
