Ignition tumber R&R, DIY job?

[SHYNE]

I just ordered a new tumbler for my ignition.

It is hard to turn the key over when I place it in.

I thought I would get it done now versus have it break later.

I ordered it from my dealer, $154.80 Canuck dollars, is that fair?

If I have the right tools, can I "give 'er a go" myself or should I take it in?

Please advise, much appreciated as always.
