A Landrover ignition switch provides the electrical signal needed to start your engine. When this switch fails, you need to replace it. After you've removed the switch, however, you need to install the new switch. In order to get the proper switch fitment, you need to make sure you have the right switch. This may sound obvious, but Landrover use a transponder inside the ignition key. If you did not purchase your ignition from a Ford dealership (as of 2008, Ford sold its Jaguar division to Tata Motors, who now owns Landrover), then you need to buy a factory-original ignition switch and have your key reprogrammed.
Slide the key into the ignition cylinder and switch assembly and turn the key to the "II" position.
Align the ignition switch and cylinder assembly with the ignition mounting hole on the right side of the steering column.
Slide the switch and cylinder into the hole and orient the switch until the entire switch and cylinder assembly can be pushed all the way into the steering column.
Push the switch into the steering column until it snaps into place.
Turn the ignition key to the "off" position and remove the ignition key.
