Key Security Question

My computer went into the shop a few days ago, and I was unable to take my PGP keys off it before it went in. What are the security risks here? If the repairman chooses to snoop through the files, what would he be able to do with my key pair? Will I need to revoke the key and make a new one, or will I be relatively safe since he doesn't have my passphrase?
