I have a 99 chevy blazer that just turned 200,000 (proud of her) I have had some goofy problems with my ignition. The security sensor activates itself sometimes when I start up my car which disables the injectors so my car shuts right back off. I have to go through the ordinary ten minute wait until it resets. Sometimes this takes 3 periods to finally reset and fire up normally. A friend had the same problem and he went ahead and replaced the tumbler and also the security sensor down on the colum. But with mine when I go to start it sometimes it takes a little playing with the key because i cant get ithe key to turn over in the tumbler. But after messing with it I can get it to turn over after a few seconds. Should I go ahead and replaced lock and tumber and also go ahead and do the security sensor or do you think it may only be the lock and tumbler? Any tips on doing this? Please help I appreciate it.

Sounds like the key is pretty worn from years of use. This could be the cause of all of your troubles. The passlock system reads the key as it is inserted across the tumblers. If the key is excessively worn, it is likely that the passlock system would see it as an invalid key.
Do you have another key that has seen less use? If so, do you have the same problems with this key as well? The dealership should be able to cut you a new key based off of your VIN. I do not think it is exactly cheap, but its an option.
Just a note, if you change out the ignition cylinder, the key for the door will be different than the key for the ignition.

The security light coming on and setting the Passlock system off usually indicates a failing ignition switch, which runs about $60. Fixes the problem.
You however, since you say you sometimes have to finagle the key in the cylinder...I would think that you might actually have a perfectly fine ignition switch, and that either your key, or your ignition cylinder (tumbler) is bad. Both the ign. switch and the ign. cylinder run about $60. You should get a new key with the cylinder though...if so, that would be optimal, as I''m sure 200k miles of starts can result in a pretty well worn key!
