3 =3D 7 >5 - 3 =3D 2 >B - 3 =3D 8 Why not just write the number in hex? 372= 8 ends up being x'E90'. Let your average crack head make something out of t= hat.If you hide a key in a small space, put a large dead spider in front of it.= That should discourage further exploration.

BTW,I bought myself a MasterFlow MF-1040 12V air compressor,so I can inflate a low tire while away from home or gas station. living in an apartment,it's well worth it.I have no place to keep a 120VAC compressor,and no outlet close to the car to plug one in..
You could. The methods I showed were ones where the computation is VERY easy (my reason for working on only 1 digit at a time). This encoding/decoding can be done in real time, with no aids (like calculators), writing NOTHING but the result.
BTW, I like to use '$' to indicate hex, so 1963 = $7AB

hid the key in a really good hiding place, then put an old, obsolete key in a fairly obvious hiding place. I figure that anyone finding the old key will try in in the door, see it doesn't work, and quit looking for more keys. >> >> >>>

This is really good stuff. Guess I'll squirrel it away in a database. I do have a combination lock or two but I never use them. Many years ago I bought a matched set of Master locks that all use the same key. So much easier to use a key than fiddle with combination locks.

I think I'll get a statue of a convict in a prison uniform and hide things up its butt, nobody would ever think of looking there. ^_^

Suspect Denies Owning Cocaine In His Butt
Honest officer, I don't know how that dope got up my butt! O_o
So now, if you get pulled over for speeding and the cop doesn't like what he smells, he will search your butt? O_o
TDD
Why not believe him? He looks like an honest guy and would not lie. He may have been sitting in the wrong place or at a bar and he thought the guy next to him was just fondling his ass.
These things happen don't they?
With a combination lock, it's harder for someone to steal the key. Maybe that's why they used combination locks on school lockers.
Check this out: O_o
It's *much* easier to steal a combination than a key and it's not noticed when it goes missing. When I was in school, locks were bought from the school and they maintained a list of combinations (IIRC, it was just a hash of the S/N) and they had a master key for the locks. There was no expectation of privacy on public property, even then.
Yes. I don't lock my doors when I drive, but a lot of people do.
I have to take the door apart to add something. Now that you make the same point, maybe I'll look for whatever stops the inside door handle, and if it's not the same thing that stops the outside door handle, I'll defeat it.
The shop manual won't show it, i'm sure.
Just like the phony house key under the mat, I use to keep imitation cocaine in an obvious place in my locker, so when they found that and tested it, I figure they wouldn't look for the well-hidden real cocaine.
Last four or five cars I've had the door lock when you put the shift lever in Drive.
We rent a lot of cars and that is the first setup option we turn off.
My wife's car locks the doors when it starts moving. My truck doesn't auto-lock the doors, at all.
I turn off the infernal seat belt alarm on mine.
Pot? Yeah that is mine. Coke? No! That is not mine. Car keys?..........Yeah, those are mine. Have you seen a remote for the TV?
