Secure Your RV Storage Compartments – Replace CH751 Locks

Did you know that many travel trailers, fifth wheels and other RVs share the same key for their storage compartments? It’s true. Others may be able to open your storage compartments with their key. It is a dirty little secret in the RV industry.

If any of your RV compartments have a CH751 lock, consider replacing them with custom made cam locks that can be opened ONLY BY YOU.

How Do You Know If You Have CH751 Locks?

You’re likely to find CH751 locks on travel trailers, fifth-wheels and some Class C motor homes. You’ll know if you have them by simply looking at the key that opens the storage compartments. It will have “CH751” stamped on it.

Where To Buy CH751 Replacement Locks?

The best option is to work with a locksmith who can customize a full set of replacement locks that are keyed alike.

Take a look at each of your compartment locks. You’ll probably notice some variations in each one. The lock depth will vary based on the thickness of the compartment door. Also, the latch part of the lock (cam) can also have different bends and curves in it.

Ordering Online from Industrial Lock and Hardware?

Industrial Lock and Hardware is your best option. They are a small locksmith located in Palmdale, California that also sells CH751 lock replacement kits for RV owners. Each kit is customized specifically for your RV. It doesn’t matter how many locks you order, you’ll have one key that opens them all.

Note: Ordering CH751 replacement locks like these on Amazon is another option, but I don’t recommend it. Customized options and quantities are very limited.

I ordered my replacement CH751 locks from them a long time ago and have been very pleased with their product and service.

In early 2020, I had a chance to drop in to their store in Palmdale to see how the locks were made. Here’s a video that will tell you more about them.

How to Replace The CH751 Lock

Repeat these steps for each CH751 lock you want to replace. After the first lock or two, the rest should only take a few minutes each.

  • Step 1: Remove the latch (cam)

    Use a screw driver to remove the latch (cam) and adjusting washer from the back of the lock. Take note of the placement of the adjusting washer so you can position the new one correctly.

  • Step 2: Remove the nut

    Use an adjustable wrench to unscrew the thin nut on the back holding the lock in place.

  • Step 3: Remove the old lock

    Slide the lock out from the front of the compartment door.

  • Step 4: Insert the new lock

    Position the new lock in the hole and insert it from the front side of the cabinet door. If your new lock comes with a rubber washer, be sure to place it between the lock and the door to prevent water from leaking in.

    If you ordered a lock cover, then that will need to be installed between the lock and the door as well.

  • Step 5: Screw on the nut

    Thread the new nut on the back of the bolt and finger tighten it to secure the lock.

  • Step 6: Attach the latch and adjusting washer

    Place the adjusting washer and latch on to the end of the lock. Be sure to position each in the same orientation as the one you removed.

  • Step 7: Insert Screw

    Use a screw driver to attach the screw to the end that holds the latch and adjustment washer in place.

  • Step 8: Tighten and test the lock

    Use the key to test the position and motion of the latch to make sure it locks correctly. Make any adjustments to the latch and adjustment washer as needed. Then tighten down the bolt and screw to complete the installation.
