From Sony's Unlock Your Bootloader FAQ:

If I change my mind later on, is there any way to restore my device?

No. Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys. You can however use the Flash tool for Xperia™ devices to flash a generic Sony ROM, although it will not receive automatic software upgrades.

The unofficial Flashtool software can also relock the bootloader.
