Asymmetrical keys

[sivlogkart]

Keys for standard house lever locks have symmetrical keys, so the same key can be used from either side. How easy is it to buy locks of this type that have asymmetrical keys, so you need different keys for either side?

Such a lock could be useful to me.

Thats why they invented digital locks etc

Wouldn't you just re-arrange the levers?

[sivlogkart]

That is true, you could do that for the lock, but the locksmiths around here do not seem to want to cut a key from a code, rather than just copy a key.

So in a professional opinion, what is more secure? Lever or pin?

Chubb used to in their detainer range but I suspect the answer is now no.
I know several properties with asymetrical keys but that was me.
Useful why?

Which is the more expensive, lever or pin?

[sivlogkart]

A related question, is if you know the bitting of a key you want made but no key to copy, how many locksmiths would cut it for you?

The answer has to be that if you are in the exact situation of wanting to fit this lever lock to your door, and you have the lock, and for the sake of argument you have rearranged the levers; then if you take the lock and the original key into a locksmith, then the only reason he wouldn't cut keys to code for you would be that he isn't equipped to cut keys to code.

In other situations where you went in with just a piece of paper with the required cuts, then it would be possible to get a refusal on ethical grounds.

Sorry if that's all obvious.

[sivlogkart]

That is good news then. Basically what I was thinking of doing was get two locks and shuffling all the levers between the two locks, but essentially the same situation.
