Input:
Question: Is there a locking cable for this unit? Where do you get the locking cable?
Document: BUT it is only secured when the safe is locked, because a cam engages that grabs the rabbit end of the cable. As long as you check this each time, you're ok, but I can easily see unlocking the safe, taking something out or putting something in, and then locking it - while the cable has become dislodged and therefore not secured.
I was concerned that maybe the hole and cable locking system was flawed, so I inserted the cable, closed the lid and locked it, and swung the safe by the cable around my yard for a while to see if I could dislodge it. Thankfully I could not, which means I just hadn't fully inserted the cable into the hole on the safe. I point this out so you don't make the same mistake and risk poorly securing your pistol.
Recreational and target shooters will find this case useful as well, for transport to and from the local range.I've been using an inexpensive NanoVault case for car storage, and while it's relatively inexpensive (under $30), it's not terribly secure,  and it's not terribly roomy. This case is an improvement in every way. It's larger, much more rugged, it has a more solid locking system, a thicker anchoring cable, and something that should be obvious for a travel safe- a handle!
Sorry for shouting, just wanted to make sure you could hear me over all the gunfire.This will hold a handgun, a few extra magazines (I think the in people call them clips), and maybe a box of cartridges (or bullets if you want to do some last minute reloading). The case locks securely and in a way that there's no place to set a pry bar. Locking the box also secures the 0.2&#34; steel cable.
I own aGunvault GV1000D Mini Vault Deluxe Gun SafeandThe Club LB200 Personal Vault Security Lock Box. This safe is more like the latter, in that it's designed to secure guns and other valuables in a vehicle, primarily, but the SentrySafe is a more elegant design with an easier mode of entry. I like that you can secure the cable to either end of the safe, and I love the clever cable locking mechanism (locks when the lid is closed, unlocks when the lid is opened).
I do think I could break into this safe in less then 2 minutes with common power tools, so secure the box to something solid!! !The reason I drop 1 star off the rating was because  of 2 reasons,1st  It does not come with or have a place to attach a locking cable. I have modified my safe to accept one.2nd  Like others have said the buttons are SLOW to react and incase of an emergency you might find yourself pressing the keys to fast and summit a wrong code.
If you want this for self defense in case of a home intrusion, there are better choices. If what you need is a safe secure way to secure a handgun and to be able to get to it quickly but not quietly or in a panic, this is a great unit. Like most pistol safes it is pre-drilled to take anchor bolts (included) if you want to anchor it to a floor so that a thief can not run off with it.
This is a great little safeafter watching a YouTube video where this guy basically breaks into every safe on the market, i realized a few things.1. The key on this safe is the one you want, other safes with a different type of key can be opened with a paperclip.2. It has protection over the reset button, because it's behind the batteries.3. The locking mechanism is not exposed on the inside of the safe.
The safe comes with two pre-cut holes in its bottom and two lag screws and washers so that it can be screwed into a solid surface to increase the security of its contents. It also comes with two keys that operate a backup/override locking mechanism in case you forget your combination. This safe is ideally suited to gun owners who want quick access to a pistol but also need to keep their gun out of the reach of children.
The instructions that come with the safe indicate the safe will retain your code combination even if the batteries are removed. The piston-driven lid pops open immediately after the last button of the code is pushed. While there are only four buttons, the code can be set to between 4 and 6 push-button combinations (for example, 1234, 12341, and 122331). It comes with two keys that operate a backup/override locking mechanism in case you forget your combination.
