Change door lock barrel

This is the part that comes in the kit, and that's what I want to install. You can do it yourself without pulling anything apart because I've done it before at least twice but that was about 20 years ago. I do remember that once you pulled that tumbler out, the new one pushed straight in.
Anyway, I'm going to have a go at it later today.

 

There's a pin hole on the ignition lock where you push in a small screwdriver to release the tumbler, pretty sure there isn't one on the door lock.

 

Too easy. Just pry off the stainless cover, turn lock fully anti-clockwise (LH door). Pull tumbler out (with a bit of wiggling, it's got to overcome a small leaf spring in the door lock itself). Clean out debris, it will most likely be the tang on the old tumbler. The tang is designed to break before the key breaks. Some CRC, then push in new lock.

 

Update:
Obviously I changed the tumbler in the driver's door as well, but the door handle was worn, so I bought a new one. It's also easier to change the tumbler and barrel with the door handle off. But what's this? Is nothing sacred? Paid the US price as well
