i assume you're speaking of a asymetric cryptographic key pair. is this PGP/GPG, SSH?
in general, cryptographic keys expire because of an expiration date stored in the key pair itself. expired keys are still mathmatically valid, but most programs will not honor them. (think "Expired ID" not "Expired milk")

I've got keys at least a year old still working.

To what I refer it is to the final user's of applications password. Is it possible that this password expires?.
I need that every so often it is requested the user the change of password in an automatic way.

Take a look at the 'passwd' command. You can set the maxiumum number of days that a password can remain unchanged, the number of days prior to expiration that the user will be warned about the password, and the minimum number of days between password changes. You can set this from the command line or from SAM.

If you want SSH keys that expire you could consider using Kerberos tickets as your keys. That way an expirey is automatically built in.
