For the OP, as others have noted virtually all older RV's used the venerable CH751 and many still do. I have at least half a dozen CH-751s sitting around from when I worked in the RV industry and from my old Coachmen Class-C. Chicago 1101X used to also be common on older Thor (Establishment) and Airstream products as well as the entry doors on Coleman tent trailers (I have no idea if they still are).
Since Georgie Boy used to be a subsidiary of Coachmen, and my former 2005 Coachmen Class-C used CH751's on the compartments, I would have almost bet yours does too. Looking at new Pursuit models on the Coachmen site it also appeared that it uses the same simple latch mechanism, two to a door, that my Class-C did. However, I downloaded the 2005 Georgie Boy Pursuit owners manual from the Coachmen site and it appears it uses the same type of Tri-Mark single lock/double latch mechanism that my Winnebago has. Images of 2005 Georgie Boy RV's online also showed this type of mechanism. IMHO, this is a heavier duty arrangement. If so, you might want to try your entry door keys to see if they fit the compartment locks. BTW, if you didn't get one, a pdf file of the Owner's Manual can be found here.
http://www.coachmenrv.com/OwnersManuals/14218574.pdf My Winnebago's basement compartments use the same Tri-Mark key as my entry lock with the exception of my utility compartment (Water, electric, dump, cable) which shares a Tri-Mark key with the water fill hatch.
I love having more secure and less commonly keyed locks on my compartments but, lets face it, it's not gonna stop anyone with enough time and who really wants to get in. It also didn't stop the low-life who stole our spare tire out from under the rig at an RV resort in Tualatin, OR last summer.
