How to renew certificate inside .sis file?

good morning to everyone,

Currently, i working on Symbian s60 3rd edition theme file. And i had found a problem, when i create a s60 3rd ed theme file with certificate included (using Carbide.ui), i notice that the theme file will only works within a period (1 year), after expiration, the theme is no longer usable.

So, is there any way for me, to renew the certificates, so that i would not have to create all the themes that i have, all over again? I may want to do it in batch manner, any suggestion or help are all welcome.

My idea is : get all the sis files, extract out the certificates, put in new certificates, that all. But i has no idea on how to do this.

Still confusing,

Yes, signsis -u.
