I've got some very large storage doors on the basement of the 5er with the standard-issue CH751 locks. The locks are finicky, and the quart-turn stops are all broken on the latches so they spin around and around, leaving you to guess when the tabs are actually engaged to the frame and holding the door closed.I upgraded to the round 7-pin tumbler locks on the previous TT and they were a little better but don't think I will go that way again. These are typical towable 3/4" thick storage doors, not the heavier Class A doors that use slam latches. Several of the doors are so big that they have 3 latches, 2 thumb turns with a locking latch in the middle.Any suggestions for "upgraded" latches?

Hope there are some good answers to this. Having same issues with my older RVs. Problem now is they have tried to make different keys in sets so everyone with an RV can't open your RV compartments. But then you have some locks with one key number and some with another so you need more keys on your key ring.Trouble is the sets of locks you get in a bag have keys made of some cheap metal that twists with the slightest turning strain, and the ends break off in the locks, and the keys get stuck in the locks so you can't pull the key out. It is all very frustrating.The compartment doors are so thin but not all the same so you have to get the right length to fit. As noted in the OP, the catch to keep it in place is not very good. The screw holding the latch tab won't stay tight either.Needs a dedicated spray can of penetrating oil just to keep all the locks working each trip. Phooey! So I'm with the OP hoping for the correct answer.Here are some, no idea which are any good.https://www.amazon.com/rv-compartment-locks/s?k=rv+compartment+locks

I hope we are talking about the same latches. I find I have to disassemble mine every couple of years, clean and regrease the ball bearing for smooth operation. The stops are solid leading me to believe your entire lock may be rotating. I would check to see that the outer bezel isn't moving.My trailer came with combination locks on some of the hatch doors and I would advise against them. I have to get the readers out to see the numbers and my eyes are pretty good. Plus, they have a large serrated handle perfect for Channellocks.

I have replaced all of mine on my 2006 Tioga with These from RV locks&More,they can all be keyed alike with heavy duty keys so I only have one key for everything. Just pick the size and how many you want. I also like that they have a cover on the key slot that moves when you insert the key,thus keeping all grime out.

Cam locks like this?Just go to your local Home Depot or Lowes and buy standard off the shelf replacement generic cabinet door cam locks.Search through their stock and pick out the locks which have the same key number. Cheap and effective.Unless you are hiding valuables like gold, silver or diamonds there is no need for a higher security round lock.Keep in mind, most of these locks (including the round key) the interior body is nothing more than zinc "IE pot metal" and what isn't pot metal is mild steel so they can be easily defeated with a screw driver or pry bar placed around the hatch..Since the inside body is pot metal, it tends to corrode easily making the pins or the lock barrel stick from weather exposure over time.To combat that, a light spritz of spray oil once and a while will reduce the effects of water intrusion. Typically on outdoor locks one would use a dry lubricant like graphite, I found on pot metal locks dry lubricants do not work. My "go to" is a product called TriFlow which is a oil mixed with Teflon..Spray it right into the key hole and insert key and rotate a few times to spread the oil.Yes, with the initial spray your key will have some oil on it, you simply wipe off the excess oil off the key and after a few times the key will no longer get oily.

The problem is that if they are cam locks. Yes any locksmith or big home improvement or hardwar can likely sell you replacements.If they are things like "Tri-mark" latch systems that might not work well. Oh the CH-751... I was talking to a woman about water issues.. She told me she did NOT have a gravity fill port for her fresh water tank.I took out MY Ch-751.. Opened the door and showed it to her.

The hard locks are the slam latch locks. Would like to replace mine with different keys but I don't think that is possible. Have to lube them every few times we camp to keep them able to lock on the latch side. Use a silcone lube on them to keep them cleaner. Getting to be a real issue.

Silicone lube is the reason you have to relube often.

Silicon lubes once the transport liquid evaporates doesn't leave behind enough silicon to do any world of good..

Have tried it on vehicle door gaskets when the automotive world got rid of the old rain gutters.. The gutterless doors in the middle of a long cold winter snap end up frozen solid to the gaskets.. Spraying with silicon would only help for one or two times and then freeze up solid..

The exact same thing happens in door locks..

That is why I started using the TriFlow I posted, it is oily, it will leave a oily residue behind and it also contains something far slipperier than silicon called Teflon.. There is a reason as to why they don't use Silicon as a non stick coating on skillets..

The oil in Triflow prevents moisture from attacking the pot metal in the lock. This is very important, unprotected pot metal when it is in contact with water or moisture from the air corrodes into a white powder, the powder helps to jam the lock.. Making things worse is as the potmetal corrodes, it swells up, getting larger in size which combined with the powder ruins the lock.

Spray the Triflow in, insert key, rotate a couple of times and pull key out. Wipe oil on the key off and repeat key in and out a couple of times. This removes extra oil from the key slot.. After that, no more oil on key and your lock will not get stuck. I use this on any lock that is outdoors to prevent freezing in cold weather and rusting stuck. I only have to reapply Triflow once every 5 or so yrs on my outdoor locks..

I went with these combination storage locks about 8 years ago.

Combination Locks on Amazon

i've never looked back and haven't had any issues with them spinning.
If your existing locks are spinning, the nut on the back has come loose and you're going to need some sort of washer to stop it from spinning.

The cam locks above don't come with washers - so you're going to need to find them online (e.g. McMaster-Carr)

I went with the dark finished locks as the chrome/polished finished ones are harder to read.
(black with white numbers is easier to read at night)

in the 8 years I've had the combo locks, i've never had a problem with them not working well. I've found that the metal behind the lock has gotten bent when DW doesn't full open the lock and the metal of the lock strikes the lip on the inside... but that's operator error not a defect of the lock itself.
