This will do the job very well. Heavy metal box construction. Very pleased with this purchase. :)

Some reveiwers seem to think that since the numbers can be entered in any order this product is worthless. They also make a big deal about only being able to use each number once. Other reviews suggest "upgrading" the mounting hardware.The instructions list how many possible combinations there are based on how many numbers you use. I believe 5 numbers yields the most combinations which is over 200.First of all a thief would have to first guess how MANY numbers you used. How on earth are they going to know that? Then they would have to try every combination of that length of numbers. Keep in mind that EVERY time you enter a series of numbers you have to try the open button. As soon as you do that the lock resets and you have to start again. Every attempt a thief makes using more or less numbers than you chose is simply additional wasted time and exposure.If you really think a thief is going to sit there and keep trying while also trying to remember which combo of 200 possible number sets they've tried without using a large note pad or an excel spreadsheet you do not understand the criminal mind. Thieves fear exposure and observation and move on to easier targets.The smart ones won't even bother, they'll just kick in the most out of sight door or throw a brick through a window. The dumb ones will do the same after wasting time in a futile attempt to open this box. The end result is the same. If a thief wants to get into your house, they will get in without wasting time trying to get your precious key.Next: Mounting hardware. The screws that come with this box are perfectly adequate in length, size and strength. Using the screws provided will yield a box that requires a sledge hammer, crowbar or reciprocating saw to remove. All of those methods make a hell of a lot of noise and we all know thieves like to draw a lot of attention to themselves right? Ah, no.But then, guess what? Even if they do get the box off they still have to open the damm thing!I can tell you that is going to require AT LEAST a hack saw and a nice bench vise.That said, I could open this box in about 7 seconds with a cordless angle grinder.When is the last time you saw suspicious characters walking around with angle grinders?I will say this. You must drill pilot holes in wood for the provided screws or you'll wind up stripping the heads when your driver bit "cams-out". Or, yes, you could use Torx screws to eliminate cam-out. The fact remains, the strength of the fasteners is a non-issue.If you still want this box but you're concerned about any of these issues just mount the box out of sight, and preferably somewhere where tools can't get any leverage or purchase on it. Thats' what I did. It's not readily visible and only my family members know where it is.Otherwise this box is not for you. Buy one of those "hide-a key" rocks and put it in the garden. The reason I didn't go that route is we have a yard service and it would be highly probable that someone would eventually flip that fake rock over. Also, we have guests we let come over when we're not in town. Try telling them which rock to look under?Nope. Just get this box, mount it out of sight and only disseminate the number to trusted parties.So, this box is perfectly adequate for me. Built like a tank, easy to use.The only time I would worry about this box if if I found it missing completely because that would mean the thief knocked it off, took it and now has time and access to tools to cut it open. At that point it would be time to re-key my locks.

good for disabled mum in case of emergency.

Tengo dos de estos en casas que rento para vacaciones, me han salvado de tener que ir a recibir huéspedes tarde en la noche. Sólo les mando la contraseña y les comento que hay que empujar el botón de "open" hacia abajo. Son bastante seguros, llevo un par de años usándolos y nadie los ha abierto a la fuerza, uno de ellos tiene marcas de que alguien lo intentó pero no pudo.

Muy macizo, fácil de programar y de abrir. Está hecho para que las llaves queden pegadas a la puerta y uno no se las lleve. Si se suelta el cierre, se tiene que poner de nuevo el NIP para cerrarlo.
