Does anyone know how much Acura dealer would charge? If not how many labor hours?

 

I'm not sure how much the Acura dealership will charge you, but I will say that you can easily change it yourself. You just need the $20 part, and a phillips head screw driver. Takes 10 minutes.

 

Don't know what year you have but I think that there was a recall on some of the early model years....check online if covered.
Several videos YouTube and some step by step here.
I can't imagine dealer charging anything less than $200 (and probably more)

 

Where can I find the part for $20? Most places I've come across want $100+ for it. I have an '05 TL

 

Ignition switch or key cylinder? The ignition switch is not the part where you put the key in.,,,,

 

This is the one I bought for my 2004 TL, literally replaced it two weeks ago. Very easy.
