Lost my Key. Need information about the key and transmitter

[nonickatall]

Hi everyone, I have a problem. I bought the truck with two keys and two remotes. One of the keys was already quite worn, and it sometimes sticks when you turn it in the ignition. I had the good key copied, to have a decent one.

Then my wife lost one of the keys and the remote, and I still had a working key and remote.

Now I've misplaced that key and can't find it.

To get the truck moving at all, I reactivated the old key, which is stuck in the ignition, but with a bit of finesse, it at least works.

So now I need a new keys and new remotes.

About that I have two questions:
Can you order keys pre-cut using the chassis number, or how can you salvage such a key?

Or do you have to order a key blank? Are there different types, or are they all the same for the GMT-800?

And the second question is...

Is it possible to buy the transmitters and program a vehicle without having an old transmitter?

There are no chips in our keys, so any blank can be cut to work.

The fobs/transmitters/remotes can be added to your vehicle without requiring an original as long as the ones you get are the same frequency range as factory. I believe the frequencies change with the electrical system going class ii (2000-2002, 2003-2006).

the key can be cut from the key code, you would need to visit a gm dealer with proof of ownership.
the fob is probably easiest to replace with a dorman kit that comes with a obd plug that only works 3 times, so
be sure the battery is charged and that you follow the directions.

Let us know how you resolved this, when you do.

Supposedly you can remove the key cylinder and the code is printed on there. I will be doing that soon..
There are ebay sellers that will cut you a key from the code, or they sell factory cylinder/locks and key sets for $125.

This is the one I'm thinking about going with, because I'm not confident a new key only would fix my issue..

one thing to be aware of
some replacement lock cylinders cannot be re-keyed
if you replace the lock, then you "might" also have to do a security relearn as the HALL sensor is inside the housing, hence no chip keys on the gmt800's
