Note: BOLT locks permanently code to only 1 vehicle. They cannot be re-coded or re-keyed.


Installation

To install this lock simply insert the ball into the coupler's ball socket. Insert the collar into the base plate until it's snug against your trailer latch and the holes align with the holes in the base plate. Insert the lock through the holes in the base plate, and use your vehicle's ignition key to secure it.


When you insert your own key into the cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key. When the key is removed, the cylinder moves into the locked position. When the key is turned again, it will rotate to the unlocked position.

Video Transcript for Bolt Trailer Coupler Locks - Surround Lock - BL7032490 Review

Speaker 1: Today we're going to take a look at the Bolt trailer coupler lock for one and seven-eighths inch, two inch, and two and five-sixteenths inch couplers. This one's for the late model GM key. This will work with most late model Chevrolet and GMC cars and trucks. Now, this is a universal coupler lock that'll protect your trailer from tow away theft by preventing hook-up. The lock cylinder that's used uses bolt technology and it codes to your vehicles ignition key. Basically, what happens is, is when you insert your own key into this cylinder, spring loaded plate tumblers will move up and down until they're matched exactly to that key.The first time the key is rotated in the cylinder, it's uniquely coded to that key.

When that key has been moved to the cylinder, moved into the locked position, and then when the key is turned again in there, it will rotate to the unlocked position. One note on this, the bolt locks do permanently code to only one vehicle and it cannot be recoded or rekeyed. Also, on this cylinder, they use a six-plate tumbler sidebar on the lock to prevent picking or bumping.On the plate in the shackle, it's a hardened steel hardware for extra security. Now, you do use the interchangeable ball on the steel-based plate that you insert into the ball socket on the coupler. Basically, the smaller one that I've installed already on here fits the one and seventh-eights inch and two inch diameter couplers.

A larger one, you'll use if you have a two and five-sixteenths coupler.The steel collar right here, just take the pin out, slide the pin out. The steel collar is a seven position steel collar. This will help restrict the coupler latch movement, so when you put your coupler in here, and put this collar over it, that'll help keep the latch from opening. If you notice on the plate, and the collar, it's a red and black powder coat finish on it to help resist corrosion and they use a red color on the plate because it makes it a visible theft deterrent.Now, this does include everything shown here on the table: the bolt lock cylinder, the base plate with the two interchangeable ball sizes, the steel shackle that'll fit most coupler and latch tiles, the steel pin that goes through that the cylinder attaches to, and nice set of detailed instructions on how it all operates.What I'm going to do now is I got a coupler here I'm going to demonstrate how you would lock it up. I happen to pull a, this is a two inch diameter coupler.

It fits on two inch balls, so that's why we have the smaller ball on the ball plate here. You'll take your shackle off, and then what you'll do is just open your coupler just like that, drop it on to the ball, lock it down into place, and now it's hooked to the ball plate. Then you'll take your shackle and drop that over the top.If you notice on the ball plate, you'll see there's two rows of slots here, so you pick the correct row that this shackle will go through that'll hold this latch down. On this one, the front one won't work because you'll miss the latch, so you'll do it on the back one. You can see it covers the latch.

Once you get it down all the way, you take your steel pin, slide it right through, match the holes up. Once you get it all the through, then you'll take your bolt cylinder that you already keyed to your ignition key and then put that right on there and it locks it into place. The only way you could get this off is to have the ignition key that you have to fit in there.Then you'll see, once it's all locked into place, you can't lift the latch up to remove it and there's no way to hook up to any vehicle to tow it away. Just to remove it, again, your lock will be on there, put your key in there, unlock it, take the cylinder off, slide the pin all the way out, pull the shackle out, and then just open the latch to remove the coupler from your lock. Simple as that.That should do it for the review on the Bolt trailer coupler lock for one and seven-eighths inch, two inch, and two and five-sixteenths couplers, and this is for the late model GM key.
