I'm betting you bought a bad battery. It happens occasionally. Remove the battery and try the glovebox again with no battery in the FOB shorting it out.
A new expression is coined........"I farkeled my fob".....

"I farkeled my fob"
Can you say that on the Forum?

Your car may very well have trouble getting into the program mode...but that has nothing to do with this problem. Keep messing with the fob battery and connections. It is also possible that you got a bad battery.

And what we are trying to tell you is that you have 2 problems. Your FOB(s) are not working AND you are having trouble with the key switch. Getting it into programming mode will do no good as long as the FOB is dead. Solve the FOB problem(s) first and at least you will be back to where you wanted to be by just changing a weak battery. You will have a drivable car. THEN you can worry about why it won't go into programming mode which most people will never have to do in the life of the car.

There are 3 parts to the FOB system - 2 FOBs and 1 car receiver/transmitter. If only one FOB doesn't work, that FOB has a problem. If neither FOB works then the car has the problem.

Ok well I have 1 good FOB and 1 FOB with a fresh battery that will not work...it was fine until the battery got weak now its worthless as I cannot get the car into programming mode. If my 2nd FOB went dead I would be f**ked. This is a ridiculous system.

As FortMorgan said above, they are separate problems. You are not in trouble because "now its worthless as I cannot get the car into programming mode", because programming mode will not help you with this fob. Because of the battery change, it is not working and even if you were successful in getting the car into the programming mode, that would not change the fact that this fob is not working right now. If you did get the car into the program mode, it is possible that something could go wrong and then neither fob would work...right now you are still OK with one good fob. Check the fob battery voltage while it is in the fob, make sure the contacts are touching correctly and also try this fob in the glovebox slot with the buttons to the right.

Battery is good..checked and double checked, inserted correctly and zero response in the glovebox slot.

So explain to me what would happen if I bought a new FOB never been used and I couldn't get the car in programming mode?

That's the real issue..lets say for the sake of arguement this FOB is toast and I bought a brand new one...how would I program it?

I can't with the current system.

Basically this is going to require a trip to the dealer.

I think what everyone is trying to say is, you should not be trying to get into programing mode. You have one good fob. The other fob does not work. Putting a new battery in does not require re programing. There is something else wrong with your fob and it's failure to work. Programing is not the answer. Have someone else look at your fob tha has a clue.

Sounds like the slot in the glove box should also be checked while it's at the dealer's.

There are many pages in that thread of tips from others for getting the car into the program mode but ultimately, if they don't work, then the dealer is the last resort. If you end up taking it there, you have a choice. They can either force program the newly purchased fob with a TECH II tool without touching the metal key, or they can repair the system so that it can be put into the program mode by turning the metal key in the trunk lock. Make sure that you understand which one they are going to do...as it would be bad to want to use the program mode a year or two down the road and find that it can't be done yourself. I know it's alot of reading, but there are many many tips that have worked for others there...patience required.

I can't with the current system.

Spend some time tomorrow inspecting the FOB where the battery is placed to make sure that all of the contacts are clean and connected to the circuit board. I have seen FOBs that worked fine until a new battery was installed and upon inspection I found the solder joints for the contact the battery sits on were loose so it was just like there wasn't any battery in the FOB. Dealer will sell you a new FOB and charge you for diagnostics but you might just be able to avoid that if you check to see if everything in the FOB is in good shape. If it isn't, it might only take a few seconds with a low wattage soldering iron to fix it.

Find and fix the problem component and life will be good again. Programming isn't the issue, a failed component is.

I assume the other FOB works? If so, try swapping the batteries between them. New batteries being bad is not at all unknown.

Could the connection tab/terminal been damaged during the battery change? One of the techs at my dealer advised me that is possible to do, hosing the FOB in the process.

I hope that's not it, but may be.

battery is good, It appears if a new FOB is obtained, then it will not be able to be programmed as the program mode on the car will not work

Correct that you or Robert can't program it, but for some scratch, a Chevy dealer can.
