Review on Motorcraft SW6389 Ignition Switch Cylinder by Philip Latham

What has made working with my existing key a lot easier is that I have experience recoding apartment locks. Although the mechanisms are different, they have enough similarity to apply to this type of two-way key. It also helps if you have a micrometer to measure the settings on the button so they match the correct toggle switches. Once you've identified the correct tumblers and made sure they're all level after keying in, use the included packet of lube liberally as it will help hold everything together and avoid having to chase the tumbler springs.
