Where is a reputable place to purchase?

I just found them from Ebay sellers with large sales and high ratings. never had a problem on the FOB's I purchased. I think it will be tough to find a source with lower prices.

Just make sure exactly which FOB you need when ordering.

crolled through 8 pages of irrelevant information on the master key programing topic.
Looked through philosophical debates on morality and discussions on key fobs....

Needless to say i have a 2015 Silverado and this method of self programing does not seem to work for my 2015.
Silverado_2011 may be correct that i had read this and if i cant sort this out by monday will have to get my truck towed back to the dealership looking like a bafoon.

Alright, hate to be a grave digger. But this is a great thread to have people who haven't seen it have the chance to as it seems very helpful.

I do have a question, from what the stealership tells me and what I read online no possible way can you have either the chip key itself or fob programmed by yourself, on a 2011+. But reading this thread it looks like you guys are saying up to at least the 2015's I can program the key myself? I just would hate to go pickup my key at the dealership tomorrow morning and laugh at them when I say no to the programming and then come back a couple days later to have it programmed lol.

EDIT, heard this only works with vehicles manufactured in the USA, mine was shipped from Mexico to Canada. Hoping someone still can prove that wrong?


So here is what i have.
the 10 -10 -10 with a maximum 45 seconds between each cycle and leaving the key in the entire time ( including the 4th (crank)cycle did not work.
this same method was tried with pulling the key out on the crank cycle, to no avail.
this same method was used but pulling the key out between every cycle to no avail.

special notes:
My service security system light would not stay solid while cycling it would flash the entire time.
The service light would not turn off after any of the cycles.
My vin number starts with a 1

Lend me your knowlege/help me out guys,
Been having a pretty god awful week.

Thanks,
Matt

First take the original key that is already programmed and stick it in the ignition. Turn the key to run but do not start the vehicle. Wait until the security light goes off and then remove the key from the ignition.

Now take the new transponder key that is not yet programmed and stick in the ignition and turn it to RUN. Do not start the vehicle. Wait until the security light turns off and remove the key. The new transponder chip key should now be programmed. Test it by inserting the new key into the ignition and start the vehicle. If the vehicle starts, the key was successfully programmed. If it does not, repeat the steps above.

This is on a different GM vehicle, but shows the process and it should be the same for your truck. I know I did two of these keys myself a few years ago, and I believe this is the process I used. I am just not sure if it will work on trucks past 2013.

Only was given one key. Being an idiot i lost it/ never got a second cut.
There is currently no master for my truck; just stuck in my driveway.

Master key program

Postby coldnorthpole [OP] » Jan 21 2014, 1:03am
Hi,
I am posting this because I had a nightmare of a time going through this myself.

I lost the one and only key that I had to my 2010 Silverado. ( I know, I am an idiot)
These are the steps to program a master key that you will need to get from your dealer or other retailer.
My local Chevy dealer told me I had to have my truck towed to them so that they could fix it. After completing a little research, I completed this on my own and saved myself probably $250 in towing fees and a major headache and other fees at the dealer. Rule of thumb, do not always trust what the dealer tells you.


Programming a secondary key is not the method i require.
Programming the master key is my concern.

Thanks.

Oh, OK. Sorry, I didn't read back through the whole post. Yah, I think your only recourse is the dealer. I think years ago, they could just cut a key using your VIN number, but with the chip, I think it complicates things.
But, I think you can still get a new key cut by the dealer (with your VIN) and then program it yourself without having to take (tow) the truck to the dealer. Check out this video: https://www.youtube.com/watch?v=PVrJWz-XZ1Y&t=165s

Yeah this video is showing a model class between 2007 - 2014.
My truck is a 2015- present.

As stated in above post
So here is what i have.
the 10 -10 -10 with a maximum 45 seconds between each cycle and leaving the key in the entire time ( including the 4th (crank)cycle did not work.
this same method was tried with pulling the key out on the crank cycle, to no avail.
this same method was used but pulling the key out between every cycle to no avail.

special notes:
My service security system light would not stay solid while cycling it would flash the entire time.
The service light would not turn off after any of the cycles.
My vin number starts with a 1


I will give things a try tomorrow again and see, but i literally went through this process 4 times today.

Thanks.

Confirmed that my security system indicator light does infact never stop flashing.
Had it in the on position for 30mins 10secs.

Letting the battery charge back up and i will try the 10-10-10 with the key in and no more then 30 secs between cycles shortly.

Performed a 10-10-10. to no avail.
10 minutes and 15 seconds ( 15 seconds off position) 3 times.
Pulled the key out, put the key back in and no change.
Has anyone done this/ gotten this to work an a 2015 +.
is the method different?
If not i would say this is busted for 2015 +/ the method has changed.
Any techs out there?

Thanks
