The photo to the right is from one of our customers. This van was burglarized and several thousand dollars worth of tools were taken.

The thief used a piece of old shelf metal that was laying in the parking lot to pry the handle corner and break it off. Once that piece came off, he was able to use his finger or screwdriver or other tool to reach in and move the lock rods.

A Jimmi' Jammer® would have stopped this burglary.

Now, on to the installation for your rear door.

This would be a good time to get a little tray to hold your screws and other hardware so you don't lose them.

The first photo shows a view of the REAR CARGO door. Some vehicles have the door panel trim all the way around the window, others the door panel stops at the window bottom. Either way, the removal steps are similar.

Start by removing the small plastic cover behind the handle in this photo. Use a screwdriver and gently pry the cover off the door trim. It comes off easily as it is a snap in cover.

Remove the door handle shroud by removing two screws. Use screwdriver or torx head driver, whichever is required on your van.

.The door panel is held in place with snap clips through the door metal. They can be pried away from the door skin and they will pop out of the door skin.

Your clip and/or panel style may vary, but the idea is the same, get all the clips out from the perimeter of the door panel. To get at the first clip, you have to pry the panel away from the door just a little until you can see a clip. They are metal and close to the edge.

If your van has the trim panel surrounding the window, use these steps:

Starting at the top, release the clips holding the trim to the door.

Get the longest narrow blade screwdriver you have, standing on a tall step stool or ladder, looking down at the top of the door, pry the top of the door panel away from the door a little bit so you can see between the door panel and the door. 

There are four clips that hold the top of the door panel in place and they are mounted under the seal of the window.  Slide the screwdriver into the clips and twist to pry the clip over to release the door panel.  When done right, the clips stay in the window seal. 

On this style trim, once these clips are released, the panel will slide up and off the door.

Looking up and in the door cavity. The lock rod goes upward to the latch on this door which is different than on the other doors on the van.

The Jimmi' Jammer® plate will wrap around the lock holder and provide a metal barrier to the lock rod.

On these vans, the handle studs are threaded into the plastic handle. We use a vice grip on the end of the stud, (there are no threads here,) to hold the stud while the nut is loosened.

Put the vice grip on the end of the stud, leaving room to get an open end wrench or adjustable wrench in to loosen the nut.

Once the nut breaks loose, you can release the vice grip and remove the nut from the stud.

Bring the plate marked for the REAR CARGO DOOR into the door cavity. The bend on this plate will go toward the outer door skin, it will only fit one way.

Make sure the plate cutout for the lock assembly goes most of the way around the lock cylinder holder as shown here. There is a small piece of Jimmi Jammer plate above the lock to help prevent breaking of the lock holder by the thief.

Put the nut back on and snug it down. Be careful not to over-tighten.

Use the circular clamp provided with the kit. Open the clamp so that the ends separate. Now you can get the clamp around the lock cylinder plastic holder.

Put the clamp on as shown here. Make sure the head is accessible for tightening.

Position the clamp and tighten it snugly. Make sure the plate is on so that the far edge shown here is BEHIND the lock rod.

Now use your door key to test that the lock still functions properly.

Installing the Lock Stop Screw™

Photo 9

Your kit will have a Lock Stop Screw™ for each swing open style door. (Not used on sliding side doors.)

Use the screw provided for the rear cargo door. The idea here is to align the screw with the back of the lock cylinder to prevent a thief from punching the lock straight into the door cavity. (Another popular method of entry.)

Before drilling, look at the next two photos to see how the screw should align with the lock cylinder.

When satisfied that you can get the screw aligned properly, mark a spot on the door skin and drill a 1/4" hole in the door skin.

The photo to the right, Photo 9, the screw hole location is marked with an arrow.

Photo 10

Photo 10 shows the lock stop screw already affixed to the door skin.

Try to make the hole so the screw will be as straight as possible behind the lock cylinder.

If alignment is correct, drill a 1/4 " hole on your mark.

The provided washer goes against the inside of the door skin, then the lock washer and nut. This screw will prevent smashing the lock straight into the door.

Note that the screw butts right up to the lock, but should not interfere with lock rotation. See the next photo.

Photo 11

This picture shows the Lock Stop Screw™ as it should rest behind the lock cylinder. It is ok if the screw end touches the lock, but it should not interfere. A small spot of grease on the end of the screw will ensure smooth rotation.

11

Once the lock stop screw, circular clamp and plate plate are in place, check that each item has been snugged down, and test the movement of the lock mechanism using the key.

Reverse the order of disassembly to put the door back together.

This completes the installation process. You can now do another door!
