On: Lockitron: Keyless entry using your phone

The user codes for these products are 4 digits, and 4 digit codes do not offer much security.

I had a 4 digit Master lock in 7th grade, and an 8th grader spent a little bit of time with the lock, determined the passcode (chosen at random), and then changed the combination.

I wouldn't put one of these locks on my home, or on anything that I wanted to actually "lock"

Some rental properties use 4 digits. On his own house my friend uses proper lock with 10 digits, for example.
