    You should make sure that your system is wired as stated. Please note that the Door locks being Ground don't mean that you can use the Keyless without Relays. Unless it is a unit with Relays already built in. Most times the output for the doorlocks are only like 250mA and your locks need more constant ground. This can be T-Tapped into the lock system.

    May want to make sure your system is using a ground to your locks. If it is tripping the fuse that sounds like your tapped into the wrong wire for the doorlocks.
