Land Rover defender hooked internal door lock button.

These are ideal for reaching the button from the top if aftermarket seats or rail extensions are fitted. The top of the button protrudes from the top of the door card and has a groove to provide grip. The interface with the control rod remains the same.

There are more variations on the way, as I develop the design further. If you have any improvements, please leave a comment or remix this model. A STEP file is attached.

Update

This is another iteration of the internal door lock button upgrade. To fit these, the door card will need to be fitted over the hook perpendicular to the door, but will fit with relative ease. You may want to check this before you commit to fitting these if you have old, aftermarket or upgraded door cards.
