Key fob stopped working - 2011 Tahoe

[Clive]

2011 Tahoe LT. Two key fobs came with it, worked great for a year. One has now decided to suddenly cease responding to any buttons. New battery you say? Replaced. Fob transmits (confirmed on a 'scope). Other interesting observation is the non-functional keyfob successfully enters Tire Learning Mode by holding Lock&Unlock down for a few seconds... further proving the remote is indeed functioning.

Anyone else had a remote quit like this? I bought 2 new ones (plus keys) and planning on a trip to the dealer to get all 4 reprogrammed (and two keys cut). Any thoughts appreciated !

They do give up the ghost, usually a solder joint breaks that holds the battery on the older ones. Are you not able to program them on the truck without the dealer that year? I can add remotes and keys through the DIC on my 2009.

The dealer will overcharge you try a local radio shop instead or an alarm installer they charge way less

Thats really weird because mine did the same exact thing last weekend. My tahoe is also a '11. Ordered a new one from amazon and going to a locksmith shop to get programed.

Can you reprogram it yourself with an obd scanner? I have a 2011 Avalanche that will need 2 new keys and fobs programmed.

Dealer wants $150 per fob and $125 per key!

So I bought two new keyfobs+keys off Amazon for $32 (www.amazon.com/gp/product/B019E48DOM) for my 2011 Tahoe, and took it to the local GM dealer. They only charged $50 to reprogram all 4 and cut the two new keys. Now I have 4 working keys+keyfobs, one is Driver #1, one is Driver #2 and the other two lock/unlock perfectly without changing the seat positions (Memory Seats/Personalization).

these are keys from a 03, 04, 12 if your key has a (+) symbol on the metal part then it has a chip, the chipped key can be programmed yourself no need to pay to have it programmed.

these are keys from a 03, 04, 12 the groove is slightly deeper on the newer key, none are chipped, GM uses a HAL sensor in the ignition housing at least on these trucks they do.

Well, do you know about programming the fobs? Can it be done with an obd scanner? Apparently the 2010 models can be done yourself, but everywhere I have read so far says you need to take an 11 to a dealership. I was hoping that they just plug it in to a scanner, but I have no clue.

2011+ has to be done by a dealer or locksmith, my understanding is that the security protocol was upgraded so it's not longer something you can do yourself.

I just called a chevy dealership near me and they said they keys have to be programmed...I asked if they had a chip, and she didn't say, but she just said that new keys have to be programmed. BUT, she said it would be $140 for 2 keys and 2 fobs after taxes.

ok if it has a (+) symbol on the metal part then it is chipped, however programming the replacement key can be done yourself, no need to pay anyone for programming the key.

I programmed an Amazon key fob to my 2011 Yukon using a Snap-on OBDII scanner last Friday. 2 minutes and it was up and running. If you have access to relatively new Snap-on scanner you can do it on your own. No locksmith or dealer needed. I plan on making a thread on it with screenshots.

Basic OBDII scanners will not be able to access the Keyless system. It will need to be an advanced scan tool with dealer level functions.

I do not have access to one of those. I will ask around though.
