Video Transcript for RockyMounts Bike Carriers Lock Cores Review

Hi everyone, It's Evangeline. And today we're taking a look at the replacement lock cores for your RockyMounts bike racks or RockyMounts accessories right here at etrailer. So I have a set of two lock cores, which includes two keys. And these lock cores are keyed alike. We can also get them in different quantities. I only need two because there's two lock cores on the RockyMounts GuideRail.

But if you have multiple RockyMounts accessories maybe more than one bike rack, you may wanna check out our larger quantities. So this is a very important part of your biking experience. You have your chain locks to lock up your bike. You also have your locks for your hitch receiver or in the case of the MonoRail here, the same lock or same type of lock that's used for both your bikes and your bike rack. This is made of zinc oxide just to make sure that it's corrosion and rust resistant.

You also have a slight dust cap on the inside. That way, when your keys are not in place, this is covered. And some of your bike racks have a rubber dust cap that goes over it for extra protection. So some of your RockyMounts racks have a plastic core and you just add the metal lock core to it. But other times maybe you broke your lock core or you wanna switch the old one out so that everything is now keyed alike.

So I'm gonna show you how to replace the old lock core and then add in the new one. So the main thing here is you need to access this wafer. So look on your own bike rack or lock core and see if you can find where that wafer is. For example, on your hitch lock. If you take off the dust cap, you can find there's the hole where you can access the wafer underneath.

Or for some bike racks in the case of the GuideRail if you take out two bolts and pop out the end cap, you can then access the wafer from inside the end cap. Make sure your keys are in the unlocked position, twist it so it is still in the unlocked position. And then you can see where you can push in that wafer. So I'm using a bobby pin. You can use a paper clip or really small screwdriver. So with one hand, I'm holding the key in the unlocked position. And with the other hand, I'm pushing on that wafer until it depresses. Now, get your new lock core. And this next step is very important because you wanna make sure you put it in the right way. If you put it in the wrong way, you will lose that lock core. So let's line it up properly. So make sure that wafer is facing the hole where you depress it. If it's facing the other way, that's incorrect. So make sure it's facing the correct way. And then you can just pop your new lock core in. Once it clicks in, you can then remove the key, pop that back in, try it out a couple times, make sure it operates properly and do this exact same process with your other lock cores. But that's how you replace your RockyMounts lock cores..

Thule lock cores are more robust - seem to be better quality , but Rocky Mount cores must be used for Rocky Mount racks.


It was supriseingly easy to replace the tumblers. I only wish the fourth one was keyed the same.

I see you also had ordered part # RKY12006

you will need to find out what the number is that starts with an E on the front of your lock cylinders. Once you know that number you can purchase a single lock cylinder with that key number. I have attached a link of single lock core cylinders.

Ordered a 1/2 dozen parts for our Thule bike rack. processed the order and shipped everything to us very fast. George followed up with me directly to ensure I received everything and was satisfied with my purchase. Great customer experience!


Out of the four keys purchased, only two worked with the rocky mount cargo bars also purchased... the keys themselves function; however, when insert d into the cargo bars, two of them failed to lock tightly and this was evident when they would give way with very little force when trying to unlach the caps. The keys and lock work, but they dont work well with the bars they are supposed to attach to.


Bought this lock system for newly purchased Jetline racks. had the best prices and shipped the products very quickly! Thank you!


Very Fast shipping. The product is extremely well built and heavy. It functions perfectly in my Utilitrak system and I anticipate it will meet my needs for bike transport. The only negative is the mounts are pricey, but the quality matches the price.


Products showed up on time and look great. Quality at a low price. I have purchased several products from etrailer and they always deliver a great value and quality products


They're lock cores. It's not complicat ed.


all good


Easy to install


Great fit
