We had a security review and this led to combination locks being fitted. Fine just make it more awkward have to remember 4 numbers now. The lock is exposed to the weather leaving mucking keys and clean keys, think about it for a second, the clean keys are the combination. Being that the order does not matter(!) just aim for the clean keys and you get in (?!). Please tell me the order matters on other locks...
The safe where I work beeps when the combination is entered.
The safe combination keypad is at eye level and easily filmed from desks to the side of it.
You can even get a clue as the the combination, based on the time delay between each beep - shorter time delays mean the numbers are close on the keypad.

At a company I used to work for, they installed one of those a shipping container computer facilities, and had a biometric lock (thumbprint scanner) put on it, even after I warned him that it wouldn't be enough.
I managed to get a copy of my bosses thumb print off his coffee mug, unlocked the door, and called him to come and see.
He wasn't happy. He had a CAC card reader installed that also required a 6-digit pin code. It was much more expensive, but at the same time, much more secure.

1. Disable the alarm by entering a pin and unsetting the correct zone
2. Present your pass to a reader
3. enter you secret 4 digit pin.
4. do your stuff
5. sign out of the room with your card (if you don't you can't get back in)
6. reset the alarm
then you get to walk away, also someone in a different part of the country is watching you on a CCTV feed to make sure that you dont eat, drink, allow un authorised people in, remove equiptment etc.
Every day, thousands of innocent plants are killed by vegetarians.
Even if you don't go all the way to personal smart cards like the CAC JSOP has the pleasure of dealing with, a digital pad that randomizes where each digit is shown will prevent clean/dirty button attacks.
Which is important because even if order does matter, 4 shiney buttons means 4*3*2 = 24 possible combinations; trivial to brute force.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
Training a telescope on one’s own belly button will only reveal lint. You like that? You go right on staring at it. I prefer looking at galaxies.
