Donflem Posted October 16, 2022 Share Posted October 16, 2022 So I’m trying to remove the trailer hitch from my motorhome and I can’t get the lock off. I’m not sure how to get the lock off do I push it in with the key turn it I’m not sure?. I push the key in but it won’t turn left or right so I’m not sure what I’m doing wrong I know it’s a simple lock but it’s kicking my butt. I was wondering if anyone know how these come off ? i’m wondering if there’s something stuck in the lock it’s keeping it from turning. Thanks for any help.

OhReally Posted October 16, 2022 Share Posted October 16, 2022 Probably rusty. Try soaking with wd40 or PB blaster. Lock should pop out to release. Cheers, Jamie. 1 Link to comment Share on other sites More sharing options...
cbr046 Posted October 16, 2022 Share Posted October 16, 2022 Or the wrong key? - b Link to comment Share on other sites More sharing options...
Donflem Posted October 16, 2022 Author Share Posted October 16, 2022 I tried spraying WD-40 in it and it’s the only key for that kind of lock that came with the motorhome. I push the key in but it won’t turn left or right so I’m not sure maybe it is the wrong key lol. Link to comment Share on other sites More sharing options...

Chuck B 2004 Windsor Posted October 16, 2022 Share Posted October 16, 2022 Hold the silver knob on the other side of the hitch when turning the key. Link to comment Share on other sites More sharing options...
JDCrow Posted October 16, 2022 Share Posted October 16, 2022 Took a large Rock Bar and snapped it off. It’s pretty weak at the locking end. Link to comment Share on other sites More sharing options...
Martinvz Posted October 17, 2022 Share Posted October 17, 2022 The key should turn to remove the head. If it is not turning then try one or more of the solutions proposed. Link to comment Share on other sites More sharing options...
Dr4Film Posted October 17, 2022 Share Posted October 17, 2022 I agree, the key should turn to release the lock head from the shaft. 1 Link to comment Share on other sites More sharing options...
Gary 05 AMB DST Posted October 17, 2022 Share Posted October 17, 2022 Is the hitch lock key the same style as the A/C access door? Gary 05 AMB DST Link to comment Share on other sites More sharing options...

If it has large flats for thumb and finger it's for the body side panel for the AC condenser. See pic If it has flats like a normal key it's for a lock. If there wasn't a rubber cover for the lock it probably has all sorts of grit in it. WD-40 is basically kerosene, which isn't much as a lubricant. I'd hit it with some high pressure parts / carb cleaner (be sure to wear eye protection) to clean it out then follow up with a real spray lubricant, maybe even a penetrating lubricant like PB Blaster / Kroil (which neither are as effective as a 50/50 acetone/ATF mix) . Once you start down the path of darkness (rock, big hammer+punch, torch, saw) it's a path that must be followed through. There's no turning back down the road of destruction. - bob Edited October 17, 2022 by cbr046 Link to comment Share on other sites More sharing options...

Guest Ray Davis Posted October 17, 2022 Share Posted October 17, 2022 If that key will open anything else, then more than likely it's not the key for the hitch. IMHO When we bought our coach, I had the same ordeal. Instead of running myself crazy looking for the key I pretty quickly gave up and cut it off.

Donflem Posted October 17, 2022 Author Share Posted October 17, 2022 I’m going to try the parts cleaning trick . Thanks for all the advice. Don 2007 Dynasty Link to comment Share on other sites More sharing options...
cbr046 Posted October 17, 2022 Share Posted October 17, 2022 It almost looks like a number stamped on the cylinder, which should match the number on the key. If not, and that is a number on the lock, a decent locksmith could make you a key. But for less than $15, (the price of a new lock, with keys!), is the question. - bob Link to comment Share on other sites More sharing options...
Donflem Posted October 17, 2022 Author Share Posted October 17, 2022 So I tried the brake cleaner trick still no luck so I’m just going to order a new one. It’s not worth the hassle when they are so cheap. I would like to know what the AC access door is? Thanks again gentlemen Don Link to comment Share on other sites More sharing options...
Ivan K Posted October 17, 2022 Share Posted October 17, 2022 I use a grade 8 long shoulder bolt with a locking nut instead. There's no breaking it off with a hammer and a potential thief would have to have 2 identical big wrenches and spend some time taking it off instead of one good hit with a sledgehammer.

Gary 05 AMB DST Posted October 17, 2022 Share Posted October 17, 2022 Ivan K, I read that grade 8 bolts are more brittle than others. They have a lower shear rate. A protentional weakness. Grade 5 are stronger. Gary 05 AMB DST Link to comment Share on other sites More sharing options...

This bolt has been there for at least 3 years and ~30k miles pulling a Hummer. I plan to replace it but still looking great. I would expect grade 5 to wear in the receiver holes and cause them to elongate with the eventual movement like the previous locking pin has. I may be be totally wrong.

Don 2007 Dynasty When you turn the key, the inner circle should pop out when it unlocks. I use one of these anti rattle devices as well. Not too noticeable on coach, but when I towed my jeep behind my pick up, I could really tell the difference when this was installed. https://www.amazon.com/MaxxHaul-50023-Tightener-Stabilizer-Hitches/dp/B07JDD8L3H/ref=asc_df_B07JDD8L3H/?tag=hyprod-20&linkCode=df0&hvadid=343227722076&hvpos=&hvnetw=g&hvrand=1614327115867578216&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031395&hvtargid=pla-693753947949&psc=1&tag=&ref=&adgrpid=68750937003&hvpone=&hvptwo=&hvadid=343227722076&hvpos=&hvnetw=g&hvrand=1614327115867578216&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031395&hvtargid=pla-693753947949 Link to comment Share on other sites More sharing options...

Use a 4” cutoff blade on a side grinder and cut it off. next….here is a Hitch Tightener that our Van Williams endorsed. Hitch Tightener for 1.25" and 2" Hitches LIBERRWAY 304 Stainless Steel Hitch Tightener Anti-Rattle Stabilizer Rust-Free Heavy Duty Lock Down Easy Installation Quiet https://a.co/d/jezB26x If the link doesn’t work, use some of the description in the Amazon search box. Compare it to the one recommended. I can tell you that BOTH are superior to the round bar stock Roadmaster one. But I own two of them….and they work. This one supposedly is better. i use a standard hitch pin in my MH. I don’t put a lock on it. BUT….IF I were super concerned about theft, I would drill out the hair pin clip and use a good Master Lock. I have a Roadmaster baseplate. It uses two standard hitch pins. I drilled them out and lock the pins in place. i figure that getting off the hitch tightener will be a deterrent….but having a stock hitch pin with a lock is a whole lot less trouble and more reliable than the chincy locking tabs inside the head that grab the grooves. MY OPINION. others will vary. BUT, when I added the Roadmaster hitch tightener, my wife noticed the difference in the ride…and it has been used for 20K. One comment. Keep tightening, but don’t overtorque. It might take a few thousand miles to get everything seated. It did on mine. Link to comment Share on other sites More sharing options...
Ivan K Posted October 20, 2022 Share Posted October 20, 2022 That's right, don't overnighten but it kept stretching and me tightening until this happened to me. But for 10 bucks it did it's job for a good while. Maybe I get an other one and use both of the plates, hmm. Maybe bolts instead of the ubolt.
