After a lockout on Christmas Day we decided we needed to upgrade the lock. Came with a wireless key fob, and 2 keys.

Some unexpected plus features:
1. Both the deadbolt and main lock are keyed identical.
2. If main lock is "locked" the door can't be shut. So no locking yourself out to begin with.
Negatives:
1. Screen door required a bit of trimming on the frame.
2. I had to swap out the two "bolts" above and below the main lock to clear the striker plate.
Other than that it's a nice upgrade with a relatively simple installation.
