Electric problems
Help!! I have a few issues going on at the same time. I was receiving the 1214 code, so I have sent my part into the ABSfixer and am waiting for it to come back. I drove the car a little for two days, then on the third, I got in, inserted the key, and nothing, even though I had a good charge. I displayed codes, and among others, got the 2723 and 1040. I couldn't find what the 1040 was, but the 2723 was something to do with ignittion cylinder, so I replaced it yesterday. The car started up, I drove it about 10 miles, then came home. This morning, inserted the key, and nothing again The battery WAS dead, so I am going to take it in and have it checked. Please, any ideas that can keep out of the Chevrolet Service Department.

When you post codes, you need to list the prefix letter ....
I'm assuming you have a B2723 and a U1040 ... have you checked for codes since you had this latest problem ??
The B2723 means that the resistance of the PASS-Key did not match the resistance the BCM expected. Simply cleaning your PASS-Key may have fixed this problem. Take a pencil eraser and carefully burnish both sides of the pellet iin your ignition key. Then clean it with alcohol or electric contact cleaner.
The U1040 can be deleted.
Good luck,

Thanks
I'll remember about the codes. I tried cleaning the key, then actually removed the ignition cylinder, took it to Chevy dealer, and they tested it (bad). Got a new one, put it in, and car started right up. Let it set overnight, tried it this morning and...nothing. I took the battery over to the parts store, and it is good. Tomorrow I'm going to work on cleaning grounds, but I wonder if the problem is in the ignition switch? Any help will be appreciated.

Check the car for codes and list ALL codes that it displays ... that's the best place to start, one of the computers may well be telling you exactly what the problem is ... especially because PASS-Key faults almost always set DTC. Let's go from there.

I was told by the dealer that temperature extremes play havoc with the keys sometimes on a sensitive pellet.
On a hot hot day, put the key in the freeezer for a few minutes, on a cold cold day, put it.......I know what your thinking........but that aint it.......over the toaster on a piece of notepad cardboard or the like, and turn on the toaster for a couple minutes.

Do you live at the South Pole and vacation on the sun? I think you should find the dealer that told you that and slap him..

Another stupid dealer statement!!!! That is NOT true! GM tested the car in very extreme climates and that was never an issue.BC

You take a part to the dealership and ask them if it's good???
I would have actually been shocked if they told it was good and that you shouldn't spend money at their dealership to purchase a replacement part.
