So i have no idea whats going on. I have had two keys made at two different places and they will not start my blazer. But they will unlock my doors. Help?

 

Its highly possible that the lock cylinder is worn. Did this problem exist prior to making the new keys? Or,why did you make new keys? Suggestion to all:keep your keychain weight as light as possible to reduce wear on the cylinder. step66

 

Had exactly the same problem. 2 made Found that one worked, other didnt. Both worked doors fine.
Found the one that didnt work, would if pulled it back slightly and jiggled. Yet the two keys lined up side by side were identical. Worn cylinder usually has troubles with the original.

 

I recently bought it and only had one key that came with it. I'm going to try playing with it today and jiggiling the key around and see what I can do. And I also might possibly try getting another key made, if you have any other ideas let me know. Ill keep you posted

 

ok good news one of the other keys it does work i just need to leave the key out a slight sliver, and a lil jiggle and it will start up thank you !!

 

So the lock cylinder is the culprit-right! Sure seems like it! Let us know! step66

 

Sure seems like it to me, Im not going to tar it apart haha, im going to leave it as it is for now. No probblem with the original key, and i got a spare to work so im going to leave it , if you dont mind poke around and look at my other posts to help
