Question edited for clarity and toss in some CAPS.
Question moved to model category.

There is no onboard programming procedure for this vehicle. This vehicle requires special equipment be connected to the vehicle to program the keyless remote. Try a locksmith before the dealership, they are usually 50% the cost.

2012 Hyundai Santa Fe Key Fob Remote Programming ...

behind and below the A/C control

For a 1994 to 2006 Sonata, a 2001 to 2006 Elantra, a 2000 to 2006 XG350 or a 2001 to 2006 Santa Fe, you will need to access alarm system control module. On most of those vehicles it is located on the driver's side fascia panel. But on the Sonata, the facia panel is in the center.

2 Once you have found this module, you will want to ensure that the memory switch is in the OFF position. Then turn the ignition on.

3 Wait 5 seconds and set the memory switch to SET position and then press the remote transmitter lock button to send the code to the alarm system control module.

4 If you would like to program a second remote transmitter then you will need to press second remote transmitter lock button.

5 Next set the memory switch to off, then turn the ignition off. You can confirm your programming by locking and unlocking the vehicle with both of the remotes. good luck my friend

DEALERSHIP WINS THEY HAVE TO REPROGRAM KEYLESS REMOTES.

This is from the factory service manual of your car:
There is no onboard programming procedure for this vehicle. This vehicle requires special equipment be connected to the vehicle to program the keyless remote. Translation you need the dealer to do this.

The procedures you list require the Hyundai Keyless Remote programming module, which you don't have. This module is proprietary - only Hyundai Dealerships have it. There is a 10 pin connector under the dash (next to the DLC - Data Link Connector) which is used to connect the Keyless Remote Programming Module. This module has two switch positions "Ready" and "SAVE". When the switch is place in the 'SAVE" position, that's when the keyless remotes are activated to send their 'codes' to the Electronic Time and Control System (ETACS). The module's switch is then set to "Ready" and the remote is tested to see if it works properly.

This bulletin supersedes TSB# 02-90-001.
DESCRIPTION: The security system keyless adapter cable (SPX/Kent-Moore P/N 09900-21300) is a special service tool (SST) that is used for programming new keyless entry remote transmitters to the factory security systems. The keyless adapter is used in conjunction with the Hi-Scan Pro (with Hi-Scan SOL Pro Software Version 09-29-03
or newer) and Data Link Connector (DLC) Cable. SERVICE INFORMATION: The keyless adapter cable can be used on the following vehicles:

• 2001 - 2004 MY Elantra
• 2001 - 2004 MY Santa Fe
• 2002 - 2004 MY Sonata
• 2001 - 2004 MY XG300/350

NOTE

• The 2003 - 2004 MY Tiburon does not need the Keyless Adapter Cable to add keyless entry remotes to the factory security system. Instead, the Hi-Scan Pro connects to the vehicle using only the DLC cable. See page BE-60 in the 2004 MY Tiburon Shop Manual for the latest instructions.
• The most current Keyless Adapter Cable Instructions are available in the following shop manuals:
