To those of you who asked for a write up on this long ago, I aplogize. I finally got around to taking pics of my creation tonight. You will not have to do any drilling into your RL. You use the stock holes that are already there. Here is how you make it.

First you will need an electric actuator. This is the one I used.

http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=330-010

The price is $4.25.

Now, you will have to go down to Lowes or Home Depot or maybe in your garage and get a set of 3" T brackets.

The price $2.97

You will need to then take one of the T brackets and take off the top leg. I used a pair of pliers and just bent the leg back and forth until it came off. If you want to get fancy, you can use a hacksaw. I didn't.

You then bolt the end that had the predrilled hole to the center hole of the other intact T bracket left in the package. I put 1 little nut in between the 2 bracket parts to make a swivel with enough room to clear the locking mechanism. I then used 2 additional nuts on the end of the bolt that are forced together so that they don't move on the bolt shaft. Here is a pic of the assembled locking mechanism. If you bolt this together correctly, it is EXTREMELY strong.



See the little oddball hole I drilled in the intact bracket on the bottom right side to the upside down T? You will have to drill this as well to line up with the stock hole in the tailgate. You then bolt it down and check for fitment. I didn't line up the holes in the picture very well but you will get the idea when you see it in person. The leg of the intact T bracket has to go under the tailgate locking mechanism as shown in the picture below. Disregard the metal rod in the picture. We havent gotten that far yet.



OK, now you will need brackets to install the lock actuator. I used the metal strip that came with the lock actuator. I used the bend back and forth method to bust it into 2 parts. I then mounted each end to the actuator first and then bent them under as shown in the picture. The screws were included with the actuator.



The trickiest part of the entire install was bending the actuator rod so that it would operate the locking mechanism. This also comes with the actuator. If you look at the last picture, the rod runs under the actuator. I can't really explain it as well as you can see in the picture.

It seems that inflation has hit the $10 tailgate lock. It is now the $11.25 tailgate lock as the price of the actuator has gone up from $4.25 to $5.50.

Sorry for the inconvenience.. :(
I have also recently installed the "poor mans" automatic lock, with the directions provided here. It ended up taking me probably 5-6 hours from start to finish, but was well worth the effort and works great. As DIY projects usually go for me, EVERYTHING took longer than expected, from fishing the wire up from the bottom of the truck, drilling the additional hole in the T-bracket (crapy drill bits), getting the proper width nut/washer between the brackets to allow for proper movement and disassembling/reassembling everything. It was good that I started this project during a few days of vacation and was in no hury. Overall I am very satisfied....THANKS CHRIS!!!
Add another to the list. Spent half a day on this and was not too bad. I had to remake both brackets as the locking arm was just a bit short the first time around, but it seems to work fine now.
My big worry is that someone really puts pressure on the handles to try and open the tailgate...Will something break inside the tailgate? If yes, then the emergency string will be no good. Maybe I need to revisit, to ensure that my failsafe actually works on the door mechanism and not the lock assembly. Again, if the handle linkage breaks, the lock will be the least of your problems it seems.
I believe that with the G2 in place, I could probably manage to release the tonneau in case of emergency, and then disassemble the tailgate, but that is not for certain as I did not think to try it out yesterday.
Thanks for the great How-To.
Big props.

I don't think you can break anything internally that easily. I thought my tailgate was frozen shut last week so I was really wailing on the handle trying to yank the tailgate open. It wasn't frozen, it was locked. I forgot that the tailgate relocks after 30 seconds if one of the doors are not opened in that time frame.

I clicked unlock and the tailgate opened as usual. No damage. :)

PS. Glad to hear you got the lock to work. :)
That is reassuring. I can see myself doing the exact same thing. Now I just need to find a good hiding place for a spare key. My reasoning is that I have an early 06 RL and cannot program the locks as described somewhere on ROC.com
I admit it, I am a copycat. I have installed the lock. I did have a few small things go wrong. The actuator I got was defective, parts express replaced it without hassel. I broke 6 of those little white clips (add 2.35 each). The latch could have been a littke longer, but it works well. I did round off the latch for smoother operation, as it was catching the action of the levers. It has only been a week, but it works like a charm. Thanks guys.
+1, Ive been here for months, about to order a dynalock, and only just found this. Ordering up the parts today. Thanks Chris and everyone else for the pics

No problem. :)
:DThanks Chris and to all the other posters on this thread. I have a Bak Flip cover ordered and on the way, so I installed the lock yesterday for a total cost of $20.12. I tested it about 20 times so far and it seems to be working fine. I priced a Dynalock at $125, for a savings of $104. Thanks again to all who contributed to this great thread.:D
thanks to this tread........mine working fine. :cool:

Just finished my tailgate lock and would like to thank ChrisM for posting and documenting the installation along with everyone else who has contributed to this thread.

I installed the actuator in a different position so I didn't have to bend the rod as much.

I positioned the actuator so it wouldn't interfere w/ the tailgate handle linkage and just put a bend in the rod. I marked the location I wanted and drilled 2 pilot holes and fastened using sheet metal screws. I would have used self-tappers but I didn't have any that long.

I used 2 washers instead of a nut or nylon spacer where the locking arm mounts on the "T" and I used a nylock nut to secure it together.

For the emergency release I used some waxed string I had laying around and routed it thru a couple self adhesive wire tie anchors alongside the wiring down to the corner of the tailgate. Like Chris I put a loop in the string but I extended it down almost even with the bottom of the quarter panel so I can reach under and pull the release. It works well.

Tested everything about 20 times before buttoning it all up. Got 2 actuators on Ebay for $10, so I have a spare if I need one. Everything else I had laying around.

Thanks again for all the great ideas!

Ok, I started out to copy the great idea that ChrisM had done making his own electric tailgate lock but somewhere along the way I got diverted from my original plan. I used some old RC linkages and scrap material I had laying around. The linkages actually ended up working very well. I also mounted the actuator similar to the way jakeman did.

Nice, very neat, clean install. Mine has been working fine since I installed it.
Great thread.

I spent part of the day yesterday installing the $10 Electric Tailgate Lock and it works like a charm.

The hardest part was re-installing the tailgate cap, but after I figured out by turning the white plastic clips 45 degrees to the square holes in the tailgate I could remove clips without breaking and re-install them on the cap, it was an easy job to simply push the tailgate cap straight back on.

Thanks to all who posted their experiences and photos of the mod -- it made it very easy and inexpensive to accomplish.

Is one of those linkages attached to a spring? I can't quite make out why there are two...

No, the other linkage is attached to a cable that is routed out to the corner of the tailgate as a backup release just in case the actuator were to stop functioning. It is hidden out of view so not just anyone will know how to get at it and use it. I think what you see as a spring is just shrink tubing with lettering that I put over the cable crimp.
I just finished the DIY poplock. I did a version of Turkey/Jakeman/Chris M. Used some stanley T plus RC car stuff and motorcycle wheel spoke for actuator arm.
Problem is the electrical hookup. I went on the Dynolock site and use their information on attaching electrical. I hooked up one wire to yellow with grey stripes and one wire to yellow with grey stripes but with black stripe. When I hooked it up my door locks wouldn't go down with key fob, only up. Have I done something wrong?

I was wondering if anyone has considered tying the electronic lock into the trunk lid circuit.

I understand it operates differently -- the trunk has a button that activates a solenoid if the car is unlocked. But what one could do is disconnect the two external handles from the physical lock and connect them to a switch instead and have it operate in a similar way.

eh, now I see some problems with it. The switch has to be 3 way, and turn off once the handle is released. And I suspect there are two mechanisms -- one for each handle.

Maybe someone more mechanically inclined could make it work...
I would like to understand the emergency release looking at Turkey picture the top cable is the emergency release, So when
using the emergency release I am pulling the tee bar from the lock position to the unlock position against the electric actuator. If this is correct how much force is required
