I am changing a full ecu kit but looking for advice on removing the ignition barrel as it looks like it’s riveted on has anyone changed over before thanks 

There is no reason to remove or change the physical ignition barrel unless you are planning on changing the mechanical key blade that you use. If so you will also need to change all the door locks, and the tailgate lock.

The barrel is secured to the steering column by two snap head bolts (not rivets). When the bolts are originally fitted they have a normal head, but it snaps off when the bolts are tightened and reach a certain torque.

I intend on changing the barrel and all the locks how do I get the snap head bolts off is it a case of drilling them out and what do I use to secure the new barrel on with thanks for the help 

You will probably a need cobalt dill bit. Replacement snap head bolts should be available from your local Ford dealers parts department.

The lock cylinder removes from the lock body.

There will be a little hole in it somewhere, put the key in and turn to position 1, then insert the pin in the hole and pull out the barrel.

 

I have had a look for this because I know  that works with the mk1 ka but I couldn’t see anything on the mk2 barrel to just remove the tumbler but will have another look thanks for your help
