Customer Review: For the money, a great upgrade over regular locks
Summary: 5 Stars
In helping someone deal with rental properties, and trying to manage expenses, one that was standing out was the cost of rekeying the locks of a triplex when tenants moved out. Since the tenants were typically students, that's 10 locks every year on one building and 8 on another. Multiply your locksmith's rate for rekeying and it's not trivial.
A friend of mine told me about these locks and as I read about how they worked, I also learned about 'lock bumping' and how virtually all pin and tumbler locks can be rendered ineffective. If you look for any articles or videos on that topic you'll see what this is.
We were forced to make a choice on these locks or a locksmith when a real estate agent's lock box (with a thin shackle) was cut from an apartment door. We needed to change the locks before the keys were taken and used to access the apartments. The cost of an 'emergency' visit from a local locksmith was high enough that I decided to try these locks. Even with the markup for the in-stock ones on the store shelves as opposed to mail order, this turned out to be a great decision. The installation was not complicated at all, so the owner replaced the existing locks instead of paying a locksmith or contractor. Once installed, changing the lock to another key can be done in seconds per lock.
We were prepared to pay a premium for a solution, but fortunately these locks are not expensive at all. They're only a few dollars more than a simple pin and tumbler lock, but offering greater security and convenience. My opinion is that for the price we paid compared to a cheap pin and tumbler lock, these are a great value, and for the flexibility they offer, I see no reason to install a pin and tumbler lock when these are available at their low price point. I'm sure that with enough thought, a number of techniques can be thought of to try to circumvent the security of the lock using it's change mechanism, but any such technique would be more complicated than bumping is on the regular lock.
This doesn't seem to be an ideal landlord/tenant system though. Master keying doesn't really work here (as far as I can tell). However, Kwikset does have a solution for that, but only in deadbolts with an option called Smart Master. If that was available for knobs and handles as well, it would be worth paying for, IMHO. We are considering removing the knob locks and going with a Smart Master setup.
There are other options for higher security locks and for quick rekeying, but the ones I've seen so far are notably more expensive. This is a very good value.
I've also read that the finish can wear quickly on these (polished brass in my case) but Kwikset seems to have a more durable finish (look for 'lifetime' in the color description), but that's a minor consideration in my case.
