Today we are going to review part number LH-003, the tailgate lock from Bully. This particular lock is specific for GMC Sierras and Chevy Silverados, for model years 1999 to 2007. Our replacement tailgate locking system consists of three pieces. We have our black plastic replacement bezel, the inner locking mechanism and then two keys. This system works great in combination with your trucks camper shell or tonneau cover to provide maximum security for your trucks bed. 0:30
Let us go ahead and take a look to see how easy it is to install one of these on our truck. The first thing that we need to do is go ahead and remove the original bezel that is on the vehicle. To do that, we need to release four clips. There are two here at the top and two here at the bottom. We are going to start by releasing the top clips and to do that we just want to take a flat head screwdriver and go ahead and pry in there until you hear them release. And then for the bottom clips, they are actually facing down. So we need to actually lift up on the bezel to get those to release. Next, we want to go ahead and open the tailgate. We need to remove the bottom retaining bolt. And then we can go ahead and close the tailgate again and we are going to go ahead and start installing our locking mechanism. 1:25
What we are going to do is feed it into the opening here. And what we are going to attempt to do is align this hole in the top of the mechanism with the hole from the screw that we had just removed. So what we want to do is go ahead and the key into the locking mechanism and go ahead and rotate it down. Go ahead and align the two holes. And then, with the provided screw and washer, go ahead and it from the inside of the tailgate and thread it into the locking mechanism. And with the locking mechanism installed, you can see that now in the open position the inner workings of the tailgate are allowed to work freely. 2:04
When we rotate it into the lock position, the arm of the locking mechanism comes up into position and prevents the handle from opening. And install our new bezel And again we want to make sure that we place the clips in properly. We want to go ahead and put the bottom clips in first into the holes. We will rotate it up and go ahead and set the other ones into position. You can see we have perfect alignment with the locking mechanism below. And that is all there is to it. In just a couple of minutes we have our new locking handle into position and it has a great OEM look to it. And that will conclude the review and installation of part number LH-003 from Bully.

I recently purchased one of these for my 04 Silverado. I watched the video on instalation and let me tell you, It really is that easy.But like the instructions say "if it's too cold warm the new one before installing. I wound up breaking the two upper tabs on the old one trying to remove it. It was very cold. Today I installed the lock in just 2 minutes.Earlier today it was only 16 degrees so I warmed up the new one by wrapping it in a towel and sticking it by a heat vent in the house for about half an hour. Went outside and popped it right on. A little tip for you. Put a piece of duct tape on the tailgate right at the edge of the old plastic. I then used a small plastic putty knife to slide under the cover and another to find the exact location of the tabs. A great product & I highly recommend it. The service from etrailer is unbeatable.

I searched the NET for tailgate locks, found several. ETRAILER's OEM integrated lock and their installation video stopped me in my tracks and made for an instant sale, instant purchase. This product installed easily and exactly as shown (1,2,3). Believe me, it looks and works as well as any factory or authorized service shop job, for a lot less loot. Thanks R W West 28957

Took about 10 min to install. Instructions were great and the lock looks great on my truck. I was told by the GMC dealer this type of thing doesn't exist. I could not be happier about my purchase and encourage anyone looking for a tailgate lock to give this one a shot. Jeff27093

Device is easy to install, but be careful when doing it. Try not to break original plastic handle cover(you might want to use it again). When installing DON'T TIGHTEN the screw holding the lock in place, especially if you use the security screw. If you do, the lock won't work and tailgate won't close...ask me how I know. Adjust screw with tailgate closed. Lastly, get some 3m double sided adhesive and place on new replacement plastic to keep it attached. My cover didn't snap in place and fell off on the first bump I hit. Thanks to great customer service, etrailer.com got manufacturer to send me a replacement. With better fit and instructions I would have rated this item higher as locking unit and replacement cover were well made...just a little tricky to install easily.25819

Very easy to install. No problems with the supplied hardware. I only wish you could reuse the same bolt that you take out as it is larger and retains factory look and matches if you've got a sprayed in bedliner. The keys supplied are huge, bigger than the factory ignition key. They don't need to be that big. The plastic overmold barely fits on the keyring. The supplied bezel matches the factory look 100%.18146

I installed the lock as per the instructions. It worked great for a while then it started to jam and I thought i would not be able to open my tailgate. I took another look at the installation and it was installed correctly. It works sometimes and other times I have to play with it to make it work. I have sence stopped locking my tail gate.13383
