How to Replace RV Storage Locks


When you lock the storage compartments on your RV, you assume the contents are safe, right? Well this may not be entirely true, given that almost 60% of all RVs are outfitted with the same locks and corresponding keys. So if you can unlock your exterior storage compartment to unload your camping supplies, about 2/3rds of all the other campers in your campground can too. RV manufacturers do this on purpose to save money. Universal keys mean fewer lock combinations that need to be made. While it may benefit their bottom line, it does nothing to give you peace of mind. Now, having said that, I don’t want you to be suspicious of every camper who casually walks by your campsite and says hi! Generally, most folks are just out there to relax and take in the peace and tranquility of nature. Not steal your stuff! But if you want to add another layer of protection so you don’t worry about your belongings while off hiking or sightseeing (or even while your RV is in storage!), you can replace your global RV storage locks with ones that have unique keys. This way, only you will have a key that works to open your exterior storage/baggage doors. Replacing the old with the new is easier and faster than I thought it would be!

RV Storage Compartment Lock Replacement


In about 10 minutes per lock, you can remove and replace your global CH751 locks with a more secure locking system. Follow these easy steps for removal of your current lock:

  1. Unlock and open your storage compartment door.
  2. Using a screwdriver, remove the cam. This is the metal piece that turns to open and close the door.
  3. Next, using pliers or a wrench, remove the large lock retention nut.
  4. Remove the old lock.
  5. To install your new cam lock, just repeat these steps in reverse. Make sure you install the cam facing in the right direction (so that it works!). Face the “S” bend AWAY from the door when you attach it to the cylinder.

How to Measure Your Existing Lock

  1. Remove your existing lock.
  2. Measure the length of the tube from the threads to where they meet the nut. Standard tubular sizes are 5/8”, 7/8”, 1 1/8”, and 1 ½”.
  3. Measure the cam/locking arm from the center of the hole to the furthest outside radius. They are manufactured in the following sizes: 5/8”, ¾”, 7/8”, 1”, 1 1/8”, 1 ¼”, 1 3/8”, 1 ½”, 1 5/8”, 1 ¾”, 1 7/8”, 2”, and 2 1/8”.
  4. Determine the measurement of the bend in the cam. Hold it vertically by the center hole and measure in inches how far back the cam bends. Standard measurements are: 1/16”, 1/8”, 3/16”, ¼”, 3/8”, and ½”.
  5. Provide these 3 measurements to the manufacturer when ordering for a perfect fit.
