This was $55 dollars well spent. “Keyed alike” is a feature you see on more expensive RVs. The standard is to have a different key for every door and your compartment doors to have the same CH751 key that every other RV has. That is both a hassle and not very secure. The process I used is specific to Global Link locks.
I used rvlocksandmore.com to order new global link compatible cam locks for my baggage doors and and two new cylinders for my rear door that matched my front door. I was also able to rent the rekey tool from them. Total cost was $95 before I received $40 back for returning they rekey tool.
Now all my locks are keyed to a single key and my baggage doors don’t use the generic CH751 key that half the campground has.
