y Kit 6730-100 Safe Lock by Sargent and Greenleaf

I wanted to replace my digital safe lock with one that would open no matter what without having to worry about dead batteries, malfunctions or EMP’s. This lock was easy to install and has performed flawlessly ever since I installed it over a year ago. I’m very happy with the purchase. There was some confusion with whether or not it came with the key to change the combination but it did in fact come with everything that was needed.

Excellent

Every S&G lock I have has worked to expectation. I wouldn’t hesitate to buy it again.

Is good. 👍

The supplier is one of the big and highly reputable names in the locksmith industry. +1.The unit appeared new, however, it was definitely not an unopened "as shipped" product since the production date and lot number on the box (which was factory labeled for this product) did not match that on the lock.I received this product on 9/1/24, and the factory label on the lock indicated it was manufacturer in 7/24. The paint was barely dry on this thing - definitely new stock.I replaced a 28 year old LaGard electronic lock that was working perfectly on one of my ordnance lockers, however, the age of that unit made me want to swtich.The description is just plain wrong.First, the specification sheet mentions one 9V battery. Nope, this is an entirely mechanical lock with no battery.The description mentions this was tested against expert manipulation for 20 hours. Nope, at least not the industry standard testing. This is a group 2 lock. Manipulating ratings are:Group 2 - 15 minutes (by an expert, you are not going to be hit by this except in an Oceans 11 style job)Group 2M - 2 hours against expert manipulationGroup I - 20 hours against expert manipulationGroup IR - Same as group 1, but resistent to X-Ray analysis of the wheels. Reduced service life because wheel are some sort of plastic.The group 2 is the overwhelming most common safe lock, until you get into UL TL rated (TL15, TL30, etc.) safes that require a 2M. These are the kind of safes that generally cost over $10K and meet insurance industry requirements for jewelery stores.My install went easy, but had to reshape mounting holes on the dial ring because the mounting hole locations in the door were out of spec by 1/10 of an inch as there was more tolerance for the electronic lock mounting. This is NOT the fault of the lock.
