Did you know...
The most common tool used in vehicle burglary and theft is a screwdriver!
It's fast, easy and doesn't attract as much attention as breaking a window.

The good news is, we can help!

What is the Jimmi' Jammer® ?

A custom formed steel plate that bolts to the backside of your door handle, preventing thieves from prying into the handle seam or punching the lock cylinder into the door.

The photo to the right shows an actual door handle that was jimmied by a thief...>>

In this case, the thief pried under the handle to get at the lock rod inside the door. Others may try to "punch" the lock into the door, breaking the handle plastic, easily and quietly gaining entry.

This can be prevented! Read on...

The Jimmi' Jammer®, outlined in red, protects the lock components.

<< The sketch to the left shows how the Jimmi' Jammer® plate (outlined in red) uses the factory handle mounting stud to attach to the backside of the door handle.

When a thief tries to pry into the seam around the door handle, or punch the lock into the door, the plate is there to strengthen and guard the lock assembly.

We currently have many models available for Chevrolet, GMC, Hummer and Ford vehicles. To see a list of all currently available models, and more detailed information on each model, see our model list.

Another common method of entry is when the thief "Punches" the lock cylinder into the door. This is common on many makes and models of vehicle. In general, vehicles that have plastic door handles suffer the most from this problem. The photo to the right shows the aftermath of an entry of this type. Note that the lock cylinder is missing from this handle! >>>

For vehicles on which this is common, we design our Jimmi' Jammer® to prevent the lock from being forced into the door.

Notice on the sketch below how the Jimmi' Jammer® plate comes up behind the body of the lock and prevents it from being pushed into the door.
