Video tutorial

Note that the vehicle in which this video tutorial was made is a Ford Transit, but since the topic concerns various Ford vehicles, including the Ford Mondeo, it is relevant and worth considering. The immobiliser activates when the key is inserted into the ignition barrel to start the engine, but it is not recognised, preventing the engine from starting.

As the protagonist of the aforementioned video explains and demonstrates, in most cases, this is due to a broken key or a flat battery, or the outer ring of the barrel, which, when broken, no longer reads the code. We will see step by step how to remove and replace it in the images.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
