Re: Auto locking door lock with remote

["mykey4000R" <osenlouangrat@xxxxxxxxx>]

1. Does the RFID lock use rolling codes? Yes it does if you really want
to get technical. It is also set up with four billion rolling security
code.
2. How close must the RFID keyfob be to operate the lock? About an inch
away..
3. How close do I have to be to the keyfob to clone it? It is like any
other Keyfob out there.
