Photo 69 shows the inserts and the hardened steel plate. Make sure that you do not lose any of these because the lock simply will not work without all three.
With a properly cut key in the lock, we can see in Photo 70 that this lock only has eight out of ten of the wafers. The ignition lock uses cuts 1 – 8, while the door lock uses all ten cuts. Notice that there is a slot milled next to the number one and number two wafers. This slot is there to prevent a brute-force attack. If someone attempted to force-rotate the ignition lock, or to pull the plug out with a dent-puller, the plug would just snap in two between these slots. Reassembling he lock is the reverse of the disassembly.
Please note that the ignition lock that I used in these photos was a new replacement lock and I did not put any grease in it so you could see the parts better. When you service one of these locks, make sure that you use plenty of the supplied grease. This will also help hold the inserts in place as you reassemble the lock. The ignition lock uses the same tumblers as the door lock that is shown in photo 41.

The new Ford Fiesta uses the new high-security side-milled lock system that Ford plans to phase in worldwide. It also has a transponder system that is essentially the same as other Ford products.
All four use the GM Z-Keyway system and the “Circle Plus” transponder system. All can be programmed with the standard GM on-board programming procedure, which takes 30 minutes.
