No, not all RV keys are the same, but the compartment keys usually are. One universal key, the CH751, opens the storage compartments on up to 90 percent of RVs. Ignition and entry-door keys are different from rig to rig: RV doors typically use TriMark keys with about 1,000 cut combinations, and ignitions match common US auto cylinders. So your RV storage bays are keyed a like and share a key with thousands of other RVs, but your RV door and ignition do not.
RV compartment keys are universal: the CH751
One key opens the compartments of nearly all RVs, the CH751, a universal precut key. If your bays use it, your compartment locks match other RVs. Estimates put the CH751 at up to 90 percent of RV compartments, and because it can be ordered precut online, anyone can buy access. Some call it the “Everything Key,” it also opens toolboxes, filing cabinets, storage bins, and even toilet-paper dispensers. If you have one, it will be stamped CH751 or 751CH. Replace these locks if security concerns you.
Door and ignition keys are not the same across RVs
Compartment locks match, but the ignition and entry-door locks do not. RV door keys are usually TriMark, one of the most common makers, with about 1,000 unique cut combinations. Each key matches a code stamped on the front or back of the lock. That code goes into a program that gives the exact cuts, so a key can be made even when no copy exists. An RV locksmith can cut these, or you can order RV keys online (RV keys on Amazon) and bring them in for cutting.
Replace lost RV ignition keys from the code
Automotive locksmiths and ACME’s Phoenix RV Keys service cut ignition and door keys when yours are lost. RV ignition cylinders have thousands of combinations and are the same type used in common US vehicles, most often GM-style 10-cut ignitions. Just about any local locksmith can duplicate an RV ignition key.
How to replace CH751 compartment locks for security
Worried about security? Swap the CH751 compartment locks for tubular locks. Tubular locks do not use pin tumblers and give you a key that is not on every other RV. Go out to the rig first and inventory each lock: note the length and how many of each you need, since storage locks vary in length and need the correct cam. Tubular RV compartment locks (on Amazon) sell individually and in keyed-alike sets online, so one new key can still work every compartment.
Where to get RV keys
Phoenix sees a lot of winter visitors and traveling retirees, so we field many CH751 and RV-lock questions. Our lock shops stock RV keys including CH751, TriMark, Bauer, and harder-to-find SouthCo keys. Come in and we will get you squared away. Outside Arizona, many RV keys ship from online sellers precut, and any that arrive uncut can go to a local locksmith for cutting.
Keyless RV locks are an option now
RV lock technology is improving. Keyless RV entry-door locks (keyless RV door locks on Amazon) open by PIN code with a key override for dead batteries, and some use a fob so you skip the code entirely. A few manufacturers now offer this on new rigs. For replacement door and ignition keys, see our automotive locksmith service.
