I lost my key to a 1997 Chev blazer

Question edited for clarity and make some sentences.
Question moved to model category.

You are going in a very wide 'around the house' route to fix something very simple and missing some important steps.

You only need another key made based on the VIN Number of the vehicle. They all have a code, and the locksmith if properly registered can cut you a key to fit based on the key code assigned to the VIN.

Then you have to have the anti-theft chip in the key linked to the ECM (engine control module) to allow you to start the vehicle. Get two keys made. You are supposed to have a key cut when you lost key number 2 and were only left with 1 key..

This is not an easy repair due to anit theft requirements. need to chisel off bolts.

Hi,

If you are trying to remove the steering wheel to change the ignition switch, then you may not have to. The switch is on the steering column about 1/2 down towards the floor, and has a rod that runs from the key cylinder & locking part. You dont need to remove the steering wheel, but if you do so, I suggest you to take some help from some Paint and Body shop so that they can direct you to do it properly and safely.

Do let me know if it helped.

I don't think the key and tumbler is your problem at all. The switch is down on your steering column. It's either loose and sliding around when the rod pulls, or it's wrecked. They can cause all kinds of problems. Just drop your steering column and take a look.

If it shifts from 1st to 3rd gear also, then you need to have it rebuilt.
I lost reverse and 2nd gear in mine and I had it rebuilt.
Works great now and for the low price of only $1600,,,LOL

o.k... you broke the key off in the cylinder... right... o.k... can you turn the key? it you can... usually you just put the key in the acc position... and just pulls out... now... some ignitions use a pin to keep the cylinder in... just hope you don't have one... because you'll have to pull off the steering wheel and the turn signal switch... just to get to it... them you'll have to get a small screw driver and remove the pin... not easy... any way... just use a big flat head screw driver... and ever so gently... pry out... when you get a new one... reverse the procedure to install... hope this helps man
